5.2 Windings

All the low and high voltage windings aremade up of copper bands (foils) or aluminium

wire (foils) .Voltagebetween layers is low , while

layer capacity is great . Its lighting

impulsewithstand capacity is high . The reactance

of high and low voltage is the same . There is nohelical angle . For ampere turns of the high and

low voltage windings are best leveled, the

windings are capable of withstanding short

circuit . Therefore, they have high operating

reliability.

Molded with epoxy resin at high vacuum ,the high and low voltage windings have well

electrical and mechnical performance . Partial

discharge of them is less than 5pc.

High and low voltage windings can beequipped with ventilating air passages according

to requirements for heat dissipation. The isolating

resin on the surface is 2.0-2.5mm thick in average

, ensuring the temperature increase and strength

of the windings and securing the 30 years service

life .

Because of quartz powder on the epoxyresin and the glass-fiber net banded inside and

outside the windings , they have high heat-

dissipating ability , humidity-resistance and flame

resistance . There is no need to worry aboutcracking . They can work normally under the

humidity of 100% . Their flame-resistant

performance accords with the Britain BS7806F2.

7.1. General information

Due to the absence of any liquid dielectric and

the excellent fire behaviour of transformers, no

anti-fire precautions are necessary providing

the following guidlines are followed:

The transformer should not be installed in a

flood hazard area.The altitude should not be above 1000 meters

unless a higher altitude is specified at the time

of inquiry

The ambient temperature for the transformer

to be within the following limits:

- Minimum: 250C

- Maximum: +400C

Standard transformers are designed in

accordance with IEC726 for an ambient

temperature of:

- Maximum: 400C

- Daily average: 300C

Yearly average: 200C

The local ventilation should allow the

dissipation of the transformer total losses.

In highly polluted atmospheres (metal

machining oil, conductive dust), the air coming

into contact with the device should if possible be

cleaned (filtering, inlet of outside air via aducting)

The transformer even with IP21 metal

enclosure is designed for an indoor installation.

Provision should be made for access to

connectors and tapping links.

Without enclosure (IP00) (figure 1)

In this configuration, the transformer must be

protected against direct contact.

In addition:Care must also be taken to eliminate risks of

water drops on the transformer (example:

condensation from overhead pipings).

Maintain minimum clearance to the walls

according to the following table:

7.2. Ventilation

Determination of the height and area of

ventilation grills

In the general case of natural cooling (AN)

the ventilation of the substation or of the

enclosure must ensure by natural convection

the dissipation of the heat produced by the

transformers total losses.

In case of a no sufficiently ventilation

substation, appropriate ventilation will consist

of a fresh air intake opening of S section at the

bottom of the local and an air outgoing

opening S located above on the opposite wall

at height H meters above the intake opening

(figure 1 and 2).

To ensure efficient cooling of the

transformer and sufficient air circulation, it is

essential to maintain a minimum height of 150

mm under the live section, by installing castors

or an equivalent booster

It must be noted that restricted air

circulation reduces the transformers

continuous and short- term overload capacity.

Formula for ventilation (figure 1):

and S=1.10xS

P = sum of the transformers no-load and load

losses expressed in kW at 120C.

S = area of the lower air intake opening (allow

for mesh factor) expressed in m2.

S = area of the air outlet opening (allow for

mesh factor) expressed in m2.

H = height difference between the twoopenings expressed in metre.

This formula is valid for an average ambient

temperature of 200C and an altitude of 1000m

Example:

- one single transformer 1000kVA

- P0=1780W, Pccat 1200C =9140W,

i.e. P=10.9kW

If the distance between the grills=2m, then

S=1.4m2

Forced ventilation (figure 2):

Forced ventilation of the substation is

necessary for ambient temperatures above

200C or small or badly ventilated rooms for

applications with frequent overloads.

The fan can be controlled by a thermostat

7.3. Connections

The incoming HV and LV connections can be

made from the top or the bottom.

MV side connections are made by cables

LV side connections are made conventionally by

cables, but can also be made using the very

safe alternative using Prefabricated Busbar

Trunking (PBT).

In all cases shown the cables or busbars must besupported to avoid mechanical stress on the HV

or LV terminals or HV plug in connectors.

The HV connections should be made to the top of

part of the delta connection bars. The LV

connections are made at the top of the

transformer.

Warning:

- The distance between HV cables or busbarsand the surface of the winding should be at

least 120 mm except on the flat face of the HVside where the minimum clearance will be set

by the HV terminal.

- The clearance to the outer HV delta bar shouldalso be a minimum of 120 mm.

- The resin coating, or the use of plug inconnectors does not give protection against

direct contact and the transformer must not be

touched when it is energized.

Without metal enclosure (IP00)

Standard HV and LV connections- The outgoing (or incoming) LV conductors can

be made from above or below (figures 1 and

2).

- The outgoing (or incoming) HV conductors canbe made from above or below (figures 1 and 2)

In case of an outgoing (or incoming) conductors

from below it is necessary to put a spacer

HV connections with plug in connectors (figure3)

LV connections using prefapricated electricalducting (figure 4)

On site installation is simplified as far as

possible, with very easy fitting, assembly and

dismantling:

- The transformer is delivered pre-equipped withthe PBT connection interface

- The possibility of adjusting on site by 15mm inall directions

- Connection and disconnection is achievedwithin an hour at most proving optimum

continuity of service.

Lifting with slings (figure 1)

Lifting is carried out using the 4 lifting holes

for a transformer without an enclosure and by

2 lifting lugs in the case of a transformer withan enclosure. The slings should not form an

inside angle greater than 600.

Lifting with a fork lift truck (figure 1&2)

The lifting capacity of the fork lift truck should

first be checked. If suitable, the forks should be

inserted inside the base channels after

removing the rollers.

Towing

Towing the transformer with or without

enclosure should be done from the underbase.For this purpose hole of 27 mm. Diameter are

provided on every side of the

underbase.Towing can be done in two

directions: in the axis of the underbase and

perpendicular to that axis.

Fitting the rollers

Either by lifting with slings (figure 1)

or by lifting with a fork lift truck (figures1 and 2)

In this case position the lifting forks in theunderbase channels.

- Place timbers of greater height than therollers under the channels and lower the

transformer on to them.

- Position jacks and remove the timbers.- Attach the rollers in the desired position

(bidirectional rollers).

- Lower and remove allowing the transfomerto rest on its rollers.

Check points when installing a castresin transformer

Installing conditions : installing place must be

clean and free from care of submersion under

water, especially not exposed water drops from

a ceiling of it. There must be a ventilation

means for getting rid of the heat generated

from a transformer.

Check of a transformer being taken custody for

long term : When dusts are deposited on a

transformer according to long term custody,

eliminate dusts by a vacuum cleaner or blow

away dusts by compressor, and wipe it by a dry

duster.

A vinyl package for preventing from inserting

of dusts, screws, nuts, washers and etc, must be

maintained until power is on after installation.

(when connection of 1st and 2nd terminals,

tear off partly)

Check points before receiving power

Get rid of a vinyl package, and check

connection status, insulating separation,

distance, whether alien substances remain,

whether a component is damaged, and bolt

torque.

Check whether tap connections accord with

that of a label.

When measuring values are below than above

values, check humidity, and if it is, get rid of

humidity by dryer, and measure an insulation

resistance again. Nevertheless if a measured

insulation resistance is below than the limit

value, contact with the A/S (after-sale service)

department.
