ZW8 - 12/630 series outdoor high voltage vacuum circuit breaker (hereinafter referred to as breaker) for rated voltage 12kV, three-phase AC 50Hz three-phase power system, the main to breaking closing rural network, City and small power system load current, overload current, short-circuit current. The overall structure of the product box for three-phase, three-phase vacuum interrupter in a metal box, use SMC insulation roll of paper skyrim and white insulation and ground insulation, reliable performance, high dielectric strength. Circuit breaker can be equipped roll of paper skyrim according to user needs isolation switch or anti surge protection, and other delays. Breaker spring mechanism can be used manually or motorized spring mechanism, the electric spring mechanism can install a wireless remote control. Breaker roll of paper skyrim according roll of paper skyrim to user requirements, and the corresponding controller with the composition of automatic reclosers, roll of paper skyrim segmentation, etc., to achieve distribution automation.
Use of environmental roll of paper skyrim conditions: 1, ambient air temperature: up to +40 degrees, the lower limit of - 40 degrees; 2, altitude: 2000m (if the altitude increases, the rated insulation level corresponding increase); 3, air pressure: less than 700Pa (equivalent to wind speed 34m / s); 4, the earthquake intensity: no more than 8 degrees; 5, contamination level: ; 6, maximum daily temperature: less than 25 degrees; 7, relative humidity: daily average of not more than 95%, the monthly average of less greater than 90% 8, non-flammable, explosion, chemical corrosion and severe vibration of the structure and characteristics of the place by the actuator breaker, conductive circuits, insulation systems, seals and housing components. The overall structure of a three-phase total box. Actuator can be equipped with manual or electric actuator spring; fracture in interrupter, long life, breaking capacity; built-in multi-tap current transformer circuit breakers for overcurrent protection. roll of paper skyrim Breaker for external insulation composite insulation, dry air inside the box, with a small size, light weight, appearance, operation and maintenance is simple and convenient, with no risk of fire and explosion, and no oil leakage leakage risks, is a species performance, practical, strong new products. The product can be installed flexible isolation switch.
