Abstract

The present disclosure relates to an arc ventilation system of a distributing board, and more particularly, to an arc ventilation system of a distributing board to minimize an arc flowing forward to prevent damage. In the arc ventilation system of a distributing board in which a plurality of compartments are provided, a first compartment accommodating an electric power device which can be drawn inor out, among the plurality of compartments, comprises an arc blocking part blocking a space between the electric power device and the first compartment at an operation position of the electric powerdevice.

Description

technical field [0001] The present invention relates to arc evacuation systems for electrical distribution boxes, and more particularly, to arc evacuation systems for electrical distribution boxes that prevent damage by minimizing forward arc flow. Background technique [0002] Generally, a distribution box is a device used to monitor, control, and protect the power system. Electrical equipment such as circuit breakers and current transformers are stored in the distribution box and used for the operation or control of power plants and substations. , the operation of the motor, etc. [0003] When an arc (Arc) is generated inside such a distribution box due to a short circuit or ground current, insulation damage, etc., high temperature and high pressure arc gas will be generated inside the distribution box. The distribution box needs to quickly discharge the high-temperature, high-pressure arc gas caused by this accident to the outside, so as to protect the electrical equipme...
