Introduction

High voltage disconnector is an important switch in the electrical system of power plant and substation, which needs to be used together with high voltage circuit breaker.

The disconnector is suitable for indoor devices with three-phase AC 50Hz and rated voltage of 12kV. It is used for connecting, cutting off or switching lines of high-voltage equipment under the condition of voltage and negative load.

 Feature

The main functions are: to ensure the safety of high-voltage electrical appliances and devices in the maintenance work, to play the role of isolation voltage, not to use and cut off, put in load current and cut off short-circuit current, only to be used for some switching operations without strong arc, that is to say, it does not have arc extinguishing function;

According to different installation locations, it can be divided into indoor type and outdoor type. According to the number of insulated pillars, it can be divided into single pillar type, double pillar type and three pillar type. Optional equipment is available for each voltage level.
