The invention relates to a low-voltage distribution cabinet with a pre-alarm device. The low-voltage distribution cabinet with the pre-alarm device comprises a cabinet body and a cabinet door connected with the cabinet body, wherein the cabinet body comprises a breaker chamber, a bus chamber, a cable chamber and a relay chamber which are separated from one another by steel plates; and the relay chamber is also provided with the pre-alarm device. By the adoption of the low-voltage distribution cabinet with the pre-alarm device, not only a fire alarm for an electric arc can be provided, but also the pre-alarm of a flammable and explosive gas can be provided, so that the application range of the device is enlarged. After a control unit of the pre-alarm device is started, the operation of all electric equipment of the distribution cabinet can be frozen, so that the consequence of disasters caused in the situations of unknowing or misoperation can be prevented.
Description
technical field [0001] The invention belongs to the field of electric power equipment, in particular to a low-voltage power distribution cabinet with a pre-alarm device for electrical fires that may be caused by electric arcs or explosive gases in the environment. Background technique [0002] At present, low-voltage power distribution cabinets are equipped with certain protection functions, but basically they are protection functions against overload, short circuit, leakage, etc., and there is no pre-alarm function for electrical fires and flammable and explosive gases in the environment. [0003] Through the analysis of the electrical fires that have occurred, it will be found that the fires originate from the electrical rarely, and basically originate from the distribution cabinet. This is mainly because most of the fires are first caused by various electrical reasons such as overload, short circuit or leakage. This phenomenon is first reflected on the power distribution ...
