Abstract

The invention relates to a safe cabinet-split type switch cabinet and a using method thereof. The safe cabinet-split type switch cabinet comprises a cabinet body. The cabinet body is internally provided with a plurality of independent drawer units. Each drawer unit is provided with a plurality of wiring interfaces. Grooves for wires to be installed are formed in the side wall of the cabinet body. A plurality of fans are arranged on the side wall of the cabinet body. A fire extinguisher is arranged outside the side wall of the cabinet body. The spraying port of the fire extinguisher is communicated with the top of the cabinet body. An electromagnetic attraction mechanism controlling opening and closing of a safety pin of the fire extinguisher is arranged in the outlet of the fire extinguisher. The cabinet body is internally provided with a smoke detector, a temperature sensor and a heating device. A control device and an alarm device are arranged on the top of the cabinet body. The control device receives signals of the smoke detector and signals of the temperature sensor and controls operation of the fans, the heating device, the electromagnetic attraction mechanism and the alarm device. The safe cabinet-split type switch cabinet is installed and maintained conveniently, the temperature inside the switch cabinet can be effectively controlled, an alarm can be given when open fire occurs in the switch cabinet, and the open fire in the switch cabinet can be put out.

Description

technical field [0001] The invention relates to a safety sub-cabinet type switch cabinet and a using method thereof. Background technique [0002] The existing switchgear is an important control unit of the power system, and its safety performance has always been the focus of the power industry. Especially for some important equipment and occasions, the safety of electricity use is very important, so higher requirements are put forward for the switchgear. , At the same time, once one of the instruments in the switchgear fails, it is usually necessary to cut off the power of the entire switchgear for maintenance, affecting normal work. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a safe sub-cabinet type switchgear and its use method, which are not only convenient for installation and maintenance, but als...
