Abstract

The invention provides a pressure relief device of a switch cabinet and the switch cabinet, and relates to the technical field of electrical equipment. The pressure relief device of the switch cabinetcomprises a cabinet top plate, a pressure relief plate and a plurality of arcing baffles, wherein bent edges are arranged on two opposite sides of each arcing baffle to form a buffer cavity; a pressure relief chamber is formed in the cabinet top plate and penetrates the cabinet top plate, the plurality of arcing baffles are all arranged in the pressure relief chamber, arc relief gaps are left between adjacent arcing baffles, and the bent edges of the arcing baffles are opposite to the buffer cavities of the adjacent arcing baffles; the pressure relief plate covers the pressure relief chamber,the first side edge of the pressure relief plate is fixedly connected with the cabinet top plate, the second side edge of the pressure relief plate is detachably connected with the cabinet top plate,and the first side edge is opposite to the second side edge. The technical problem of potential safety hazards in pressure relief of switch cabinets in related technologies is solved by the pressurerelief device of the switch cabinet.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a switch cabinet pressure relief device and a switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. During the operation of the switchgear, due to various reasons (such as short circuit, insulation aging and human error, etc.), a circuit short circuit fault occurs. Under the short circuit current of tens of thousands of amperes, high temperature and high pressure gas is generated instantly. If the high temperature and high pressure gas is in a na...
