HXGT8-12箱型固定式交流金属封闭环网开关设备

产品概述 Product Features

HXGT8系列环网柜是本公司为了满足域网、农网建设和改造需要,借鉴其他环网柜的长处,弥补其不足设计而成的新产品,其中配FT8-12真空负荷开关或FT8-12(FR)真空负荷开关+熔断器组合电器的环网柜的母线室与负荷开关室间通过一接地的金属隔板隔开,省去其他环网柜需要绝缘插板及其相应的连锁装置;而配VT2A型真空断路器的固定柜可做为线路保护之用,是环网柜一次接线方案的补充。

HXGT8 Series RMU is R&D for satisfying the local power grid and the rural grid construction and innovation requirements, we introduce the other RMU advantage to offset the new one products’defects, especially FT8-12 vacuum load circuit breaker or FT8-12 (FR) vacuum load circuit breaker+fuse combination appliance, its RMU bus cabinet and load circuit cabinet are divided by earthing metal panel. The equipped fixed cabinet of VT2A vacuum circuit breaker is used to protect the circuit.

适用范围  Application Range

HXGT8系列环网柜适用于额定电压为12kV,额定频率为50Hz的三相交流系统中户内配电系统,作为接受和分配电能之用。

HXGT 8 series RMU is suitable for the rated voltage 12kV, rated frequency 50Hz indoor distribution system in the three-phase AC system, for distribution and control of electric energy.
