3 Product description


Product descriptionThis chapter contains an overview of the design and function of the product.

Function descriptionThe protective relay is used to protect the on-load tap-changer and thetransformer when a malfunction occurs in the diverter switch oil compartmentor selector switch oil compartment. It is tripped when the specified speed ofoil flow from the on-load tap-changer head to the oil conservator is exceededdue to a fault. The flowing oil actuates the flap valve which tips over into po-sition OFF. The contact in the dry-reed magnetic switch is thereby actuated,the circuit breakers are tripped and the transformer is deenergized.

The protective relay is part of an oil on-load tap-changer and its propertiesconform to IEC publication 60214-1 in the applicable version or a future sub-sequent standard. Therefore, it is part of the scope of our delivery.

Diverter switch operations at rated switching capacity or at permissible over-load will not cause the protective relay to trip.

The protective relay responds to oil flow, not to gas accumulated in the pro-tective relay. It is not necessary to bleed the protective relay when filling thetransformer with oil. Gas accumulation in the protective relay is normal.

Performance featuresThe product is particularly characterized by the following properties:▪ Vacuum resistance▪ High temperature range▪ Main switching contacts with large electrical switching capacity range▪ High insulation strength▪ High dielectric strength to ground

Scope of deliveryThe product is packaged with protection against moisture and is delivered asfollows:▪ Protective relay▪ Operating instructions▪ Supplements▪ Dimensional drawing

4 Packaging, transport and storage


Packaging, transport and storage

Packaging

Purpose

The packaging is designed to protect the packaged goods during transport,loading and unloading as well as periods of storage in such a way that no(detrimental) changes occur. The packaging must protect the goods againstpermitted transport stresses such as vibration, knocks and moisture (rain,snow, condensation).

The packaging also prevents the packaged goods from moving impermissi-bly within the packaging. The packaged goods must be prepared for ship-ment before actually being packed so that the goods can be transportedsafely, economically and in accordance with regulations.

Suitability

The packaging is suitable for▪ all common types of transportation▪ stackability - 1000 kg/m2 top surface

The packaged goods are packed in a stable wooden crate. This crate en-sures that the shipment is secure when in the intended transportation posi-tion and that none of its parts touch the loading surface of the means oftransport or touch the ground after unloading.

The packaged goods are stabilized inside the crate to prevent impermissiblechanges in position.

Markings

The packaging bears a signature with symbols with instructions for safetransport and correct storage. The following symbols apply to the shipment(of non-hazardous goods). Adherence to these symbols is mandatory.

Transportation, receipt and handling of shipments

WARNINGDanger of death or severe injury!Danger due to tipping or falling load!► Only trained and appointed persons may select the sling gear and se-

cure the load.► Do not walk under the hanging load.► Use means of transport and lifting gear with a carrying capacity of >

500 kg.

NOTE

Damage to packaged goods!Damage due to tipping or falling load!► Only trained and appointed persons may select the sling gear and se-

cure the load.► Use means of transport and lifting gear with a carrying capacity of >

500 kg.

In addition to oscillation stress and shock stress, jolts must also be expectedduring transportation. In order to prevent possible damage, avoid dropping,tipping, knocking over and colliding with the product.

If a box falls from a certain height (e.g. when slings tear) or experiences anunbroken fall, damage must be expected regardless of the weight.

Every delivered shipment must be checked for the following by the recipientbefore acceptance (acknowledgment of receipt):▪ Completeness based on the delivery slip▪ External damage of any type.

The checks must take place after unloading when the crate or transport con-tainer can be accessed from all sides.

If external transport damage is detected on receipt of the shipment, proceedas follows:▪ Immediately record the transport damage found in the shipping docu-

ments and have this countersigned by the carrier.▪ In the event of severe damage, total loss or high damage costs, immedi-

ately notify the sales department at Maschinenfabrik Reinhausen andthe relevant insurance company.

▪ After identifying damage, do not modify the condition of the shipmentfurther and retain the packaging material until an inspection decisionhas been made by the transport company or the insurance company.

▪ Record the details of the damage immediately together with the carrierinvolved. This is essential for any claim for damages!

4.2

Visible damage



▪ If possible, photograph damage to packaging and packaged goods. Thisalso applies to signs of corrosion on the packaged goods due to mois-ture inside the packaging (rain, snow, condensation).

▪ Name the damaged parts.

When damages are not determined until unpacking after receipt of the ship-ment (hidden damage), proceed as follows:▪ Make the party responsible for the damage liable as soon as possible by

telephone and in writing, and prepare a damage report.▪ Observe the time periods applicable to such actions in the respective

country. Inquire about these in good time.

With hidden damage, it is very hard to make the transportation company (orother responsible party) liable. Any insurance claims for such damages canonly be successful if relevant provisions are expressly included in the insur-ance terms and conditions.

Storage of shipmentsPackaged goods can be stored outdoors when the following conditions arecomplied with.

Selection and arrangement of the storage location should meet the followingrequirements:▪ Stored goods are protected against moisture (flooding, water from melt-

ing snow and ice), dirt, pests such as rats, mice, termites and so on, andagainst unauthorized access.

▪ Store the crates on timber beams and planks as a protection against ris-ing damp and for better ventilation.

▪ Carrying capacity of the substrate under the goods is sufficient.▪ Entrance and exit paths are kept free.

Check stored goods at regular intervals. Also take appropriate action afterstorms, heavy rain or snow and so on.

Unpacking shipments and checking for transportationdamages▪ Wherever possible keep the crate packaged for transport to the place

where installation will take place.▪ When unpacking, check the condition of the packaged goods.▪ Check completeness based on the delivery slip.

Tripping of the protective relay and re-commis-sioning the transformer

WARNINGDanger of death or severe injury!Danger of death or severe injury if on-load tap-changer and transformer areinsufficiently tested!► Be sure to check on-load tap-changer and transformer after the protec-

tive relay has been tripped. The diverter switch insert or selector switchinsert must be removed in order to do this.

► Only use the equipment again when you are sure there is no damage tothe on-load tap-changer or transformer.

When the circuit breakers have been tripped by the protective relay, proceedas follows:1. Establish time of tripping.2. Determine operating position of on-load tap-changer.3. As a precaution, block the motor-drive unit by tripping the motor protec-

tive switch to prevent the on-load tap-changer being actuated by remotecontrol.

4. Check on-load tap-changer head cover. If oil is leaking, shut the oil con-servator stop valve immediately.

5. Check whether the flap valve of the protective relay is in the OFF or INSERVICE position.

Flap valve in IN SERVICE positionIf the flap valve is in the IN SERVICE position, there may be a fault in thetripping circuit. Check the tripping circuit. If the reason for the protective relaytripping cannot be found, the diverter switch insert or selector switch insertmust be removed in accordance with the on-load tap-changer's operating in-structions and checked [► 33].

Flap valve in OFF position

Note that protective relay RS 2004 features an automatic reset mechanismwhich means that the flap valve does not remain in the OFF position aftertripping. If the protective relay RS 2004 has not tripped due to an error inthe tripping circuit, proceed as described below for RS 2004 too.

If the flap valve is in the OFF position, proceed as follows:1. Ensure that the transformer is not started up under any circumstances.2. Remove and inspect diverter switch insert in accordance with corre-

sponding on-load tap-changer operating instructions.3. Contact Maschinenfabrik Reinhausen and inform them of the following:
