General description:
VS1 vacuum circuit breaker is developed by ourselves. It embodies our ideas: compact, intelligent,
environmental-friendly, energy-efficient and maitenance-free.
It adopts integral design. Its spring operating mechanism is very mature, simple, reliable. The vacuum
circuit breaker box is divided into several function units, which brings easy maintenance.
It is widely used in power distribution and transforming systems of power stations, power generators,
mines, industries, airport, subways, and residential area.
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
Test:
Our VS1 series vacuum circuit breakers have passed the following routine tests before delivery from our
factory: mechanical performance test, main circuit power frequency withstand voltage tests, dielectric tests
on auxiliary and control circuits, main circuit resistance test, interlock operation tests, mechanical operation
tests, electric operation tests,ect.
Operating mechanism:
The VS1 is equipped with a new type modularized integral double spring operating mechanism. It has simple structure. It is convenient to maintain, easy to replace and more reliable.
