Abstract

The invention belongs to the technical field of electrical cabinets, and particularly relates to a power electrical cabinet. The cabinet comprises a cabinet body and a cabinet door; the cabinet door is mounted on the cabinet body, and a handle is arranged on the cabinet door; a mounting cavity is formed in the cabinet body; a plurality of placing plates are fixedly mounted in the mounting cavity;an electrical element is fixedly mounted on the placing plate; a heat dissipation pipe is fixedly installed on the upper surface of the cabinet body; a storage cavity is formed in the cabinet body; the storage cavity is located above the mounting cavity; a heptafluoropropane fire extinguishing agent is compressed and stored in the storage cavity; the storage cavity is communicated with the mounting cavity through a switch module; after the temperature borne by the switch module exceeds a certain limit, the switch module is automatically started to communicate the mounting cavity with the storage cavity. The cabinet is simple in structure, dust can be effectively prevented from entering the cabinet body, meanwhile, when a fire occurs in the cabinet body, a channel for outside air to enter the cabinet body can be blocked, and oxygen supply of an ignition point in the cabinet body is blocked.

Description

technical field [0001] The invention belongs to the technical field of electrical cabinets, in particular to a power electrical cabinet. Background technique [0002] The electrical cabinet is made of steel to protect the normal operation of the components. The materials for the electrical cabinet are generally divided into two types: hot-rolled steel plate and cold-rolled steel plate. Compared with hot-rolled steel plate, cold-rolled steel plate is softer and more suitable for electrical appliances. The production of cabinets, electrical cabinets are mainly used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring and transportation industry, etc. At the same time, electrical cabinets are now widely used, and electrical cabinets are in use A large amount of heat will be emitted during the process, so the electrical cabinet itself needs to have cooling holes for heat dissipation....
