Description

Fireproof electrical cabinet for civil buildings

Technical Field

The utility model relates to an electrical cabinet technical field, especially a civil architecture fire prevention regulator cubicle.

Background

The electrical cabinet is a cabinet which is processed by steel materials and used for protecting components from working normally. The electrical cabinet manufacturing materials are generally divided into hot rolled steel plates and cold rolled steel plates. The cause of fire may be: the conductor is overheated and it is normal that the conductor generates heat due to the flow of current. The electrical equipment which is correctly designed, installed, debugged and normally maintained and overhauled has the maximum temperature and temperature rise which cannot exceed the allowable range, and is determined by the insulation grade and the heat dissipation and ventilation conditions or the climate conditions. However, when any of these conditions is not met, the heat generated by the conductor increases, the temperature rises, and the heat cannot be dissipated, so that the insulation of the equipment is burned out, and a fire or explosion occurs. Spark arc, the breaking or closing of a switch element, the spark or arc generated by the friction contact of a brush, the plugging and unplugging of a plug pin and the like are normal and allowed under normal environmental conditions, but in a dangerous environment where fire and explosion can happen, an explosion-proof electric appliance is required to be adopted to isolate the spark arc from the external dangerous environment without fire or explosion. However, spark arcs occurring when electrical equipment or lines are short-circuited or grounded, flashovers occurring when insulation is damaged, sparks generated by loosening of connection portions of lead buses, arc light generated by fusing of fuses, sparks generated by collision of a motor stator and a rotor sweeping chamber or sparks generated by mutual friction collision of other electrical transmission components, and the like are abnormal and are not allowed in any environment, and appropriate protection measures must be taken to eliminate the abnormal arcs or sparks, otherwise, the abnormal arcs or sparks are dangerous and may cause fire or explosion.

The existing fireproof electrical cabinet for civil buildings has the following defects: the existing electric cabinet is easy to explode when a fire hazard occurs, and has poor separation effect on the spread of the fire outside the electric cabinet.
