2 Function

2.1 Disconnector

Electrical isolation of parts of networks High-voltage disconnectors are used for the electrical isolation of electrical high-voltage networks. When switched off, they form a visible isolating distance. High-voltage disconnectors are switched under no-load conditions. Small capacitive or inductive currents, of the kind that occur during the discharge of disconnected overhead-line or cable sections, are controlled.

Outdoor installation and formation of groups Three-column double break disconnector described in these service instructions is a single-pole disconnector for outdoor installation. Three such disconnector can be coupled to form a group for three phase operation.

Standards The type eDB Three-column double break disconnector conforms to the following standards:

IEC 62271-102 and IEC 62271-1

2.2 Earthing Switch

Earthing and short-circuiting In order to earth and short-circuit switched-off parts of plant, it is possible to mount: one or two earthing switches per pole.

2.3 Variants

Selection of variant of client The type eDB Three-column double break disconnector is available in a wide range of variants. These service instructions are valid for all variants. The information on the different variants is structured in such a way that a clear distinction can be made.

5 Mode of Operation

5.1 General

The type eDB three column double break disconnector has separate operating mechanisms for the disconnector and the earthing switch.

Prevention of automatic opening or closing When the equipment is switched on or off, a dead-center position is passed through just before the end positions are reached. This prevents the automatic opening or closing of the disconnector or earthing switch as a result of:

Short-circuit External influences (e.g. storm or earthquake)

5.2 Disconnector

Figure 5 : Mode of operation of type eDB three-column double disconnector (example: 3-pole in parallel arrangement)

Operating mechanism The operating mechanism (75) of the disconnector transfers the operating energy via the operating rod (37) to the rotary pedestal (70). The support insulators (201) transfer the torque to the current-path (5), and these pass through an angle of rotation of 76° during switching.

Current transfer During switching-on the contact fingers (66) glides over the fixed contact (67). This establishes the connection between the two terminals. The current is transferred via fixed contact (67) to the high-voltage terminals (17).

1HDB050013-YN

7

Mechanical coupling inside a disconnector group:-

Via the coupling rods (15), the movement of the operated pole is transferred simultaneously to the other poles of a disconnector group.

5.3 Earthing Switch

Figure 6 : Mode of operation of earthing switch (example: 3-pole parallel arrangement)

Operating mechanism The operating mechanism (77) of the earthing switch transfers the operating energy via the operating rod (71) to the earthing-switch shaft (337). The tubular contact arm (23) swivels up (ON) or down (OFF). During switching-on, the contact fingers (20) glide over the earthing contact (18). In the ON end position, they are in preloaded contact against the stop.

Earthing connection The earthing connection (79) connects the tubular contact arm (23) to the earthed sectional-steel base frame (221) of the disconnector.

5.4 Interlocking

The disconnector and the earthing switch can be interlocked according to the following principle:

Disconnector only ON when earthing switch OFF Earthing switch only ON when disconnector OFF Interlocking is mechanical and/or electrical, depending on the version.

Notice

Mechanical interlocks between disconnector and earthing switch are fitted at the factory

Retrofitting in also possible on site.

8 Shipping and Storage

8.1 Shipping

The equipment is shipped on pallets or in boxes.

Notice

After unpacking, check all supplied equipment immediately for shipping damage. Report shipping damage without delay to the forwarding agency.

8.2 Storage

Caution

In the case of inappropriate storage of the individual components, there is the risk of ingress of water. For this reason, disconnector parts and operating mechanisms must always be stored in the mounting position.

It is advisable to leave all assemblies in the shipping packing until the start of mounting in order to protect against contamination and damage.

Special notice: operating mechanisms Operating mechanisms are supplied in special packing. This protects the operating mechanisms against corrosion within a limited time and in a dry atmosphere. It is advisable not to open this packing until just before the start of mounting.

In the case of lengthy storage and/or a damp atmosphere, there may be unde-sired formation of condensation in the operating mechanism. If the shipping time and storage time together amount to more than 6 months or if operating mechanism are stored in a damp atmosphere, the special packing must be removed immediately and the electrical heating of the operating mechanisms must be started. Before doing this, remove bags with desiccants from the op-erating mechanisms.

Caution

1HDB050013-YN

9.2 Treatment of Contact Surfaces and Intersection Surfaces

Bolted or sliding contact surfaces that conduct current have an effect on the electrical resistance of the current path. Dirty or oxidized contact surfaces increase the electrical resistance. This may result in irreparable damage to equipment.

The following regulations must be observed:

Bolted contact surfaces

Aluminum (bolted) 1. Grease lightly 2. Using a steel-wire brush, remove oxide film until surface is mat gray in appearance (do not

use emery paper) 3. Wipe off contaminated grease immediately using a lint-free cloth 4. Grease immediately (approx. 1 mm) 5. Bolt together treated surfaces and grease joints

Silver-faced contact surfaces (bolted) 1. Clean with cold cleaning agent (do not destroy silver surface) 2. Grease (approx. 1 mm) 3. Bolt together treated surfaces and grease joints

Galvanized contact surfaces (bolted) 1. Clean using steel-wire brush 2. Grease immediately (approx. 1 mm) 3. Bolt together treated surfaces and grease joints

Copper (bolted) 1. Clean using brass-wire brush 2. Grease immediately (approx. 1 mm) 3. Bolt together treated surfaces and grease joints 4. (If copper is bolted to aluminum, place copper-plated aluminum sheet between the surfaces,

ensuring that the sheet is the following way round: Cu-Cu, AI-AI)

Sliding contact surfaces

Silver faced contact surfaces (sliding) 1. Clean using cleaning agent (do not destroy silver surface) 2. Grease (approx. 1 mm) Copper (sliding)

1. Clean using brass wire brush 2. Grease immediately (approx. 1 mm)

Intersection surfaces

Steel parts 1. Coat with cold zinc 2. (If part was previously painted, allow cold zinc to dry and recoat using appropriate paint,

observing the following mixing ratio: Paint: Hardener= 12 : 1)

10 Mounting of Disconnector

If you suspect shipping damage, check the spacing dimensions of the contact fingers (66) Figure -67

The disconnector pole can be mounted either on the supporting structure or in front of the supporting structure. If mounting in front of the supporting structure, first lift the completely mounted disconnector pole onto the supporting structure and then align and tighten it there.

Remember that the materials for fixing the disconnector bases (2) on the supporting structure are not included in the scope of supply.

The transportation angles (328) Figure 13 must be mounted in place and may under no circumstances be removed during this mounting phase.

Mounting steps:

1. Unpack components.

2. If mounting on the supporting structure: Using lifting tackle, place disconnector base (2) on the supporting structure Figure 12.

3. If mounting on the supporting structure: Align and tighten disconnector base on the supporting structure.

4. Mount support insulators (201) on the rotary pedestal (70) and side stools of the structure. Adjust distance B between two insulators to 2000mm. This can be done by adjusting the jack bolts(13) on side insulators figure14

5. Mount the fixed contacts (6) on the side insulators. figure14

6. Mount the current path (5) on the center insulator such that the current path is in open position. Adjust the jacking bolts below the rotary pedestal(70) such that the current path is horizontal to the disconnector base(2).

7. Close the current path until it touches the blade on the fixed contact (6). Adjust any vertical misalignment by means of jack bolts(13) at the bottom of the side insulators

8. Any rotary misalignment of the fingers on the fixed contacts can be adjusted as follows; Loosen the bolts of the finger holder and then tap the finger holder a few times with a plastic mallet. This will allow the fingers to align with the contact blade on the fixed contact. Now tighten the bolts of the finger holder again.

11 Mounting of Operating Mechanism for Disconnector

The mounting side of the operating mechanism is apparent from the position of the disconnector operating lever (69) Figure 18. The pole on which the operating mechanism is mounted can be freely selected. In the case of mechanical interlocking, however, the operating mechanism must always be mounted on the pole with the interlocking segments.

Make sure that the operating mechanism is in the ON position (as-delivered state). If the operating mechanism is in the OFF position, set it to the ON position using the emergency hand crank (39)

In the case of a motor-operated mechanism, test operations may only be carried out using the emergency hand crank (39). Do not use a drill.

11.1 Direct Mounting

Make sure that the disconnector pole is in the ON position before mounting operating mechanism.

Mounting Steps

1. Unpack operating mechanism(75)

2. Tighten operating mechanism, on the envisaged mounting side, to the disconnector base (2) Figure 18

3. Mount operating lever (74) on the shaft end of the operating mechanism according to the mounting side Figure 19.

4. Next step: Chapter 12: Mounting of coupling of disconnectors.

11.2 Separate Mounting

In case of separate mounting of the operating mechanism for the disconnector, the mounting steps are dependent on measurement m3 of operating shaft (43) Figure 22, Figure and on a possible lateral offset of operating mechanism and disconnector Figure 25:

Separate mounting if measurement m3 < 6 m Separate mounting if measurement m3 = 6 ... 12 m Separate mounting laterally offset with measurement m1 (max. 4 m) Make sure that the operating mechanism is in the ON position (as-delivered state). If

the operating mechanism is in the OFF position, set it to the ON position using the emergency hand crank (39). The disconnector pole must be in the ON position.

If a manual operating mechanism is envisaged for the disconnector, ensure when

mounting that there is sufficient clearance for the operating lever (367) of the operat-ing mechanism Figure 21.

Mounting steps:

1. Unpack operating mechanism (75).

2. Mount pivot bearing (42) on the disconnector base (2) Figure 21

5. Insert operating shaft (43) through the pivot bearing Figure 21

6. If measurement m3= 6... 12 m: Insert individual parts of the operating shaft (43) through the pivot bearings

7. Vertically align operating mechanism by operating shaft (43) and mount

8. Calculate required length of operating shaft Figure 22, Figure 23

9. Remove operating shaft again and suitably shorten

10. After shortening, coat intersection surface with the paint supplied

11. Grease thrust bearing (330), inside, and collared bush (331), outside, with Long-term 2 plus grease Figure 21

12. Repeat mounting steps 5. and 6., threading thrust bearing (330) and collared bush (331) in the correct sequence onto the operating shaft Figure 21

13. If measurement m3= 6... 12 m: Connect individual parts of operating shaft to coupling parts (334, 335) Figure 21

14. Tighten operating mechanism and all pivot bearings

15. Connect shaft end of operating mechanism and operating shaft to coupling, parts (334, 335) Figure 21

16. Operating lever (74) on the upper end of operating shaft (43) Figure 26.

15 Mounting of Mechanical Interlocking

The interlocking segments the operating mechanism for the disconnector and the operating mechanism for the earthing switch must be mounted together on one pole.

Mechanical interlocks between disconnector and earthing switch are mounted at the factory. Notice: Retrofitting is not possible.

Make sure that the disconnector is in the ON position before mounting the mechanical interlock and that the earthing switch is in the OFF position.

Mounting steps :

1. Mount interlocking segment-1(252) on earthing- switch shaft (337 or 73) in case of parallel arrangement or series arrangement of the disconnector poles. Mount the interlocking shaft (254) along with the interlocking segment 2 (251) on the earth switch link 336. Figure 65

2. The interlocking lever (253) is connected on the interlocking shaft. This link is connected to the center insulator through a link. For the link position when mounted on the same side as main blade drive refer Figure 65b. For the link position when mounted on the opposite side of the main blade drive refer Figure 65c.

3. The interlocking segment-1 defines the position of the earth switch. While the interlocking segment-2 defines the position of the main blade (through the interlocking lever)

Fig 66 4. With the disconnector in OFF position and the earth switch in OFF position the interlocking

segments are in position shown by figure a. Both are free to move. This means either we can close the disconnector or the earth switch. Fig 66a

5. Now bring the earthing switch to ON position. Now the interlocking segments are in position shown by figure b. Now try to manually close the disconnector. The disconnector should not close as the interlocking segment-2 will try to rotate. clockwise. In this position ensure that the two segments are not touching each other and at the same time the gap between them is not more than 5 mm. Fig 66b

6. With the disconnector in the ON position and the earthing switch in the OFF position, the interlocking segment look like in figure c. Try to set the earthing switch manually to the ON position. The disconnector should not close as the interlocking segment-1 will try to rotate clockwise. In this position ensure that the two segments are not touching each other and at the same time the gap between them is not more than 5 mm. Fig 66c
