Outdoor HV Vacuum Circuit Breaker

Summarization: ZW32-12/T630-20 high voltage pole mounted vacuum breaker ( breaker for short ) is a outdoor AC equipment with rated voltage 12kV, current 630A and frequency 50Hz. The breaker is applied to interrupt the load, overcurrent and short circuit current and suitable for operating often in rural,urban and industrial power supply system. ZW32-12(D)/T630 12kV outdoor breaker combined with the isolating switch presents, in addition to the superior performances of ZW32-12/T630-20, the advantages such as visual breaking points available for checking and maintaining. The interlocking device added between breaker and isolating switch can ensure the safe operation for maintaining. Performances: 1.Principle of vacuum - arcing, reliable and stabile interrupting performance, explosion andmaintenance free 2.Integrate three phases post insulators, accord with the requirement of phase distance, usethe conductive copper staff instead of alumi num flange to prevent oxidation 3.Equipped with a small operating spring mechanism, low energy consumption foe switchingon/off, seal the operating mechanism in a box to protect from the rusting 4.Equipped with two phases or three phases CT, use the special transformers with light weight and high strength which provide the current for auto matic tripping and intellectualized controller 5.Use the imported epoxy resin as the insulating sleeves of insulators and transformers which present the advantages such as temperature resistance, UV resistance and aging resistance 6.Can realize the manual, electrical or remote operation to switch on/off the breaker, can be equipped with controller forautomatization, can be combined with controller to function as recloser 7.Realize flexible combination with isolating switches equipped with electrical and mechanical interlock to connect thebreaker and switch which provide equipment with safe operation 8.Small volume, light weight, maintenance free, long period for operation Breaker Parameter: NOItemUnitParameter1Rated voltagekV122Rated frequencyHz503Rated currentA6304Rated insulatinglevelAC voltagewithstanddrykV42wet to earth34lightning impulse voltage withstand755Rated short circuit interrupting currentkA206Rated short circuit interrupting times307Rated operating programO-0.3s-CO-180s-O8Rated short circuit switching on/off current (peak)kA509Rated short time currentkA2010Rated short time current (peak)kA5011Rated short circuit continuous timeS412Mechanical life1000013Allowed weaning thickness of stationary contactMm3
