BKV3(VS1)-12KV vacuum circuit breaker

BKV3(VS1)-12KV vacuum circuit breaker
Product Description
BKV3-12 indoor H.V. vacuum circuit breaker is an indoor switchgear with three-
phase, rated voltage of 12kV, control and protection for industrial and mining
enterprises, power plants and substations, electrical facilities, and for
frequent operation place adopting VET operating mechanism and circuit breaker
integrated design can be used as a fixed installation unit can also be equipped
with special advance mechanism, the composition of handcart unit used some of
the main circuit can use the whole solid seal post with high reliability,
maintenance-free, in order to achieve smaller circuit breakers, can be equipped
with KYN28A 12 and other handcart switch cabinet. In the home it can also be
used with fixed XGN switchgear.
VS1-Series circuit breaker features high stability and high reliability
In terms of mechanisms, VS1-Series vacuum circuit breakers are given special
optimization to transmission parts. Modular spring mechanisms have such
advantages as convenient maintenance, short power-off maintenance, high
versatility of parts, and boast better compatibility with vacuum interrupters
which greatly improves the technical parameters and delivers more excellent
performance.
Applicable standards

current circuit-breakers
Secondary circuit
VS1-Series vacuum circuit breakers adopt modular design for their secondary
control circuit boards. The electric connection of the mechanisms employs high-
grade self-fastener plugs, which both facilitates replacement and ensures
reliable electrical connection High-performance oil buffer
