Product Description

ZW20-12PT/630-20 outdoor HV automatic recloser  circuit breaker
Summary
 
ZW20HW - 12 power hanwang is ZW20-12 column on vacuum circuit breaker, FZW28F - 12 outdoor boundary vacuum load switch two products improved advanced product, with functions of manual and electric operation. Switch ontology introduced from Japan's Toshiba VSP5-12 type free maintenance load switch, mature stainless steel bellows seal structure, good sealing performance, make it not influenced by the external environment, is a maintenance free product. This product adopts vacuum arcing, SF6 gas insulated medium. Circuit breaker can be combination of circuit breaker and isolating switch, intelligent controller can be configured, self-provided PT as power, voltage, current signal output and can be controlled by intelligent circuit breaker, is smoked in the column on the circuit breaker.
 
 
Product feature

1. City, the ideal equipment of the rural electric reform: Can be matched with the controller to realize remote control, telemetry and remote setting, and realize the four remote functions.
2. Flexible operation, convenient: This product is a east electric energy storage, electric points, both hand machine, manual and combination, and be able to close or long-distance remote control operation.
3. Open circuit superior performance: The breaking short circuit current 20 ka for 30 times.
4. Operating power is small, high reliability: New design of small electric spring mechanism, part number and operation work around (about 30 w) is reduced to the lowest level.
5. Maintenance-free characteristics: The main loop of the circuit breaker and secondary components, operating mechanism are sealed in the SF6 gas gauge pressure (zero), is not affected by the external environment.
6. Sealing reliable performance: Adopts the technology of the mature sealing structure, reliable sealing performance..
7. Outlet and inlet line of unique way: Adopt silicon rubber casing, make the insulation distance between terminals, the insulation is fine.
8. Use security: Explosion-proof devices are installed on the top of the box body, even if the accident of the internal fault, also won't have high temperature gas leaked or splash.

 
Functions:
 
1, automatic removal of the user in single-phase ground fault
2, automatic removal of the user double phase ground fault in the area
3, quick positioning point of failure
4, monitor user load
