Vacuum Circuit Breaker Ve7 - China

VE7-12 medium voltage solid-sealed type vacuum circuit breaker (hereinafter referred to as circuit

breaker), a new generation of domestically leading 12kV vacuum circuit breaker in China, is independently

researched and developed by our company.

Its main feature is leading electric three-phase vertical layout, using solid seal a column or composite

insulation form, which avoid the vacuum arcing outdoor surface pollution, improving the circuit breaker

insulating ability, while improving the circuit breaker mechanical stability and service life.

Optimization design and modular spring operating mechanism are applied.

The whole body has the width

dimension of the small and compact structure, is fixed installation.

Product is adapted in compact

substations, ring net switch cabinets and all kinds of stationary, in 12 KV power system, as a grid

equipment, industrial and mining enterprise power equipment protection and control unit.

The design of

vacuum circuit breaker meet the following standards such as IEC62271-100 (high-voltage AC circuit

breaker) and GB 1984 (high-voltage AC circuit breaker).

Product Structure:

1 It has modular operation structure, three-phase longitudinal decorate, compact structure, simplicity,

the width of small size, high stability.

2 The energy storage, keeping, and institutions such as tripping important parts of the mechanism are

used strengthen treatment and surface nickel plating phosphorus processing, making the operation

system overall service life more durable, corrosion resistant, stable and reliable.

3 Trouble-free operation, maintenance or less maintenance free, no explosion danger, no pollution,

running low noise.

4 Flexible design and manufacturing solutions can meet user's specific needs, especially suitable for the

side with fixed switchgear.

5 Enhance the creep distance and maintenance free: the main circuit of the insulation strengthen,

improving the circuit breaker a loop of the insulation level and the unclean ability and achieving a loop

free maintenance, and creating the conditions for the free maintenance.
