A low-voltage switch cabinet capable of automatically eliminating a fire risk comprises a cabinet body and a cabinet door, wherein the cabinet body is connected with the cabinet door. A compressed carbon dioxide bottle is fixedly arranged in the cabinet body. An electromagnetic valve is arranged on an outlet of the compressed carbon dioxide bottle. The electromagnetic valve comprises a control end. A controller is arranged in the cabinet body and comprises a single-chip microcomputer and a power supply. The single-chip microcomputer comprises an input and output terminal. The control end of the electromagnetic valve is connected with the power supply through a relay. The input and output terminal of the single-chip microcomputer is connected with the relay and connected with at least one photoelectric sensor. When faults happen to a power supply circuit and sparks are generated on a low-voltage switch, the photoelectric sensor can detect the flash, the single-chip microcomputer and the relay can control the electromagnetic valve to run, carbon dioxide can be released in time, and therefore flames are eliminated. Meanwhile, action signals of the single-chip microcomputer can be sent to a control center having access to a network through the network by means of a serial port to Ethernet circuit module, and therefore control personnel are informed of the spark accident.
Description
Technical field: [0001] The invention relates to the electrical field, in particular to electrical components, in particular to a low-voltage switchgear that can automatically eliminate fire hazards. Background technique: [0002] Low-voltage switchgear is widely used in the field of industrial control. The low-voltage switchgear includes a cabinet body and a cabinet door. The low-voltage power distribution switch is set in the cabinet body and connected to the power supply equipment and load equipment by wires passing through the cabinet body. When the power supply line fails, some low-voltage switches will generate sparks and ignite the combustible parts in adjacent components, thereby expanding the fault. Invention content: [0003] The technical problem to be solved by the present invention is to provide a low-voltage switchgear that can automatically eliminate fire hazards. The low-voltage switchgear that can automatically eliminate fire hazards needs to solve the pr...
