Zw32-12 12kv 11kv High Voltage Spring Mechanism Outdoor Vacuum Circuit Breaker For Substation
ZW32-12/T630-25 Type Outdoor high voltage vacuum circuit breaker is a outdoor distribution equipment with AC 50HZ,rated voltage 12KV and three-phase ac. It is mainly used for open circuit power distribution network and close the load current, overload current, short circuit current in power system.It is suitable for the transformer substation and factory power distribution system for protection and control use. Especially suitable for urban power grid and rural power grids.
Structural Features
Town, country reform ideal equipment: It can be set with control mechanism to remote control, remote measure and adjustment.
Flexible operation, convenient: This product has performance of electric energy storage, electric close-open and hand energy storage, hand close-open, it also can be operated close or far remote.
Superior performance of open-shut: 30 times of open-shut short current at 20kA.
Small capacity of operation and high reliability: New designed small electric spring structure, parts numbers and operate capacity(about 30W) can be reduced to *** level.
Maintenance-free performance: Main breaker circuit and bivariate device, operate structure were all sealed in air of SF6(zero pressure)and not affected by outside.
Reliable sealability: It was used of mature seal structure technology and reliable capacity.
Special in-out line method: It was used silicon rubber pipe and make terminals distance sufficient, good insulator outside.
Safety in use: There was explosion proof equipment set on the top of box, even if breakdown inner, high temperature air or splash will not out.
Service conditions:
1. Ambient Temperature: -40℃~+65℃,daily temperature≤25℃;
2. Altitude: ≤2000m
3. Wind speed: ≤35m/s
4. Earthquake intensity: ≤8
5. Anti-fouling property: IV level
6. Installation site: Not putting inflammable, explosive, chemical corrosion.
