factory pre-assembled american type substation combined transformer

Product Description

ZBW(YB)17-10 Series     HV/LV Prefabricated (American type)Substation

Applications

The combined American box change is a transformer body, high voltage load switch, fuse and other components.
It is placed in the transformer oil tank. Because it is immersed in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance free. Widely used in residential quarters, high-tech centers, factories and mines, airports, stations, schools.

General requirements:

1.Simple lighting,public power distribution,the case into the high-voltage wiring scheme does not need to set high-pressure measurement,only low-pressure measurement or no measurement,no compensation.Feeding circuit 4-6 back,the use of plastic circuit breaker control and protection.
2.Power lighting,public power distribution,the box transformer with a change in the circuit has increased to 8 to 12 back,in addition,there should be reactive power compensation.
3.Box-type transformer substation covers small footprints,General box-type transformer substation covers an area of only 5 to 6 square meters,or even reduce the 3 to 5 square meters.Suitable for general load-inensive industrial and mining enterprises,ports and residential quarters and other places,can be extended.

Normal conditions of use

Product Features

Overload capacity strong,allowing overload 2 times 2hours,overload 1.6 times 7 hours without affecting the life of the box change.

Adopt elbow plug connector,high-voltage cable can be very convenient joint into the connection,and in emergency situations as a load switch to use,can live plug.

Double-fuse protection,plug-in fuse(BAY-o-net) for the double-sensitive fuse temperature,current) protectionbox secondary side of the short-circuit failure occurred.

The back-up current limiting fuse(ELSP) protects the cabinet from internal faults and protects the high-voltageside.
