VD4series vacuum circuit breaker is used in indoor high voltage switchgear systems. The overal l structure of it is composed of switch main body and operating mechanism. The operating mechanism is spring loaded type, you can choose electrical operation or manual operation.
It uses composite insulated material, so it does not have pollution and explosion problems.
With particular advantages, it is suitable for some network where there is high switch frequency in the working current range or where repeatedly short circuit breaking operations happen.
VD4 type vacuum circuit breaker can be used as individual units for switchgear type KYN28, AMS, GZS1, ZS1,Unigear and so on.
Applied standards
-GB1984 high voltage AC breaker
-GBT/11022 common technical specifications for high voltage switchgear and control gear standards
-DL/T403 12KV-40.5KV high voltage vacuum circuit breaker ordering technical specifications
-IEC62271-100 high voltage switchgear and control gear part 1: AC breaker
-IEC56 and similar standards in other main industrialized countries
Advantages and features
The rated voltage of VTL4 vacuum circuit breaker is 24KV, the rated current is up to 2500A and the rated short circuit breaking current is up to 31.5KA.
The VTL4 is equipped with a new type modularized single spring operating mechanism. It is convenient to maintain, easy to replace and is more reliable.
VTL4 have two installation type: fixed type and withdrawable type. Both types can realize reliable mechanical interlocking. It can be installed directly in kinds of fixed switchgears and also on the handcart of the withdrawable switchgears.
