ZW32-12 outdoor high voltage vacuum circuit breaker vacuum interrupter, air insulated, with manual or electric spring operating mechanism, making a strong product interrupter ability, the number of high short-circuit breaking, no fire and explosion hazard, easy to operate, is performance, practicality strong product. ZW32-12 outdoor high-voltage vacuum circuit breaker overall structure using solid letters column; overcurrent protection with a straight-through outdoor current transformer is placed on the line side ZW32 vacuum breaker that protects the current ratio can now set according to the user needs as: 20-1200 / 5A, 10P-level accuracy for conventional, also according to user needs with output 0.5, 0.2 or 0.2S level measurement or ratio level of measurement. ZW32 electric voltage vacuum circuit breaker spring mechanism arranged inside the box, it can be used under relatively harsh environmental conditions. Vacuum interrupter ZW32 vacuum breaker ceramic shell, goblet longitudinal magnetic field structure contacts, copper chromium contact material with excellent breaking and closing short-circuit current capability. The product is small, light weight, good looks vacuum interrupter and insulation support sleeve compact design, the outer pole qualifying conductive silicone rubber injection, can adapt to harsh weather conditions and dirty environments ZW32 vacuum breaker purposes:. ZW32-12 / 630-20 outdoor high voltage vacuum circuit breaker system 50Hz three-phase AC power system, mainly for breaking, closing urban areas 10KV grid load current, load current and short-circuit current, but also for the rural power grid division switches and small power system, more suitable for frequent operation The place is more suitable for harsh operating conditions of the environment, supporting intelligent switch controller, consisting of coincidence, a slicer, to meet the requirements of distribution automation, is the urban and rural power oil-free replacement products.
