Abstract

The invention belongs to the field of switch equipment, and particularly discloses a switch cabinet suitable for preventing burning explosion. The switch cabinet comprises a cabinet body, a thermal control chamber and a thermal control system; the cabinet body is of a closed structure formed by a cabinet door, a left side plate and a right side plate; the thermal control system comprises a circulating pump arranged in the thermal control chamber, a first heat exchanger arranged in the bus compartment and suitable for heat absorption, a second heat exchanger arranged in the cable compartment and suitable for heat absorption, a third heat exchanger arranged in the circuit breaker compartment and suitable for heat absorption, and a fourth heat exchanger arranged outside the cabinet body and suitable for heat dissipation. The thermal control system is suitable for timely discharging the heat generated in the cabinet body out of the cabinet, reducing the temperature in the cabinet and ensuring the normal operation of the switch cabinet. The internal space and the external space of the switch cabinet are isolated by the closed cabinet body, so the open fire generated in the cabinet is limited in the cabinet body and cannot influence the outside of the cabinet, the switch cabinet is suitable for places containing combustible gas and combustible dust, burning explosion accidents are avoided, and orderly production is facilitated.

Description

technical field [0001] The invention relates to a switchgear, in particular to a switchgear suitable for explosion prevention, and belongs to the field of switchgear. Background technique [0002] There are a large number of fine flour particles suspended in the air in the flour workshop. When the concentration of flour particles in the air reaches the critical concentration of explosion, it is very dangerous. The air in the workshop will explode when it encounters fire, causing safety production accidents and causing personnel accidents. The wounded, the production could not continue, and the loss was heavy. A large number of fine cotton chips are suspended in the air in the cotton spinning workshop. When the concentration of cotton chips in the air reaches the critical concentration of explosion, the air in the workshop will explode when it encounters fire, causing casualties and unsustainable production. There may be combustible gas in the mine, such as gas. When the gas...
