Abstract

The invention relates to the technical field of direct current switch cabinets, and discloses a direct current switch cabinet used for rail traffic. The direct current switch cabinet comprises a direct current switch cabinet body. The direct current switch cabinet solves the problem that most pressure relief equipment are arranged on the front face of the switch cabinet to cause the injury of personnel when pressure is relived, the left wall of a hollow cylinder is connected to a first placing box, a second placing box and a third placing box, a ventilation effect is achieved, elongated equipment placing grooves are formed in the left walls of the first placing box, the second placing box and the third placing box in a connecting manner transparently, secondly, a closing plate is connectedonto the left wall of the hollow cylinder, ventilation holes are formed in the outer wall of the closing plate for discharging gas, air pressure is relieved through a hollow block connected with thepressure relief equipment connected to the top of the hollow cylinder, and a ventilation pipe connected to the bottom of the hollow block is used for discharging air pressure.

Description

technical field [0001] The invention relates to the technical field of DC switch cabinets, in particular to a DC switch cabinet for rail transit. Background technique [0002] When the DC circuit breaker used in the DC switchgear has short-circuit, arcing and other faults, the temperature and air pressure in the high-voltage chamber of the DC switchgear will rise rapidly. pressure channel. In the existing pressure relief methods, different types of holes are mainly opened on the top of the cabinet, which are covered with simple cover plates or composite material plates to realize automatic or manual pressure relief. The pressure relief cover completely blocks the pressure relief port; when the DC switchgear is in normal operation, the electrical components in the cabinet heat up, which increases the temperature and humidity in the DC switchgear, and the air permeability of the existing pressure relief device is poor. The heat and moisture in the switchgear cannot be discha...
