Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology, the invention proposes a high-voltage explosion-proof power distribution cabinet that can be remotely monitored. When the arc generated by the middle contact electrical appliances is in contact, the power distribution cabinet is prone to explosion when it is in use; at the same time, it reduces the explosive impact force generated by the components inside the power distribution cabinet when they accidentally explode, which causes the power distribution cabinet to explode question

The invention belongs to the technical field of power equipment, and particularly relates to a high-voltage explosion-proof power distribution cabinet capable of being remotely monitored. The cabinetcomprises an electric cabinet body, and the electric cabinet body is composed of an outer box body and a rubber explosion-proof layer, wherein an explosion-proof cavity is formed between the outer boxbody and the rubber explosion-proof layer. A ventilation cylinder is inserted into a ventilation hole, and a rotating motor is arranged in the ventilation cylinder through a fixing hole disc; the output end of the rotating motor is connected with a rotating fan through a rotating column, and the top end of the rotating column is rotationally arranged in the ventilation hole through a rotating sleeve; an elastic filter screen is slidably arranged at the end of the ventilation cylinder, and an electric telescopic rod is arranged on the side wall of the ventilation cylinder. An elastic sealing plate is connected to the side wall of the top end of the electric telescopic rod through a fixing column, and the top end of the elastic sealing plate is connected to the bottom end of the elastic filter screen; dust particles contained in external air can be effectively prevented from entering the power distribution cabinet and making contact with electric arcs generated by electronic elements, thereby avoiding the explosion phenomenon that is likely to happen.
Description
technical field [0001] The invention belongs to the technical field of electric equipment, in particular to a high-voltage explosion-proof power distribution cabinet capable of remote monitoring. Background technique [0002] Most of the power distribution cabinets are equipped with electronic components and equipment. In petroleum and petrochemical, coal mines, iron ore and other mining industries, fires or explosions are prone to occur. Once danger occurs, it is easy to cause damage to electronic equipment. [0003] In the field of power distribution cabinets, explosion-proof power distribution cabinets are more and more widely used, such as: central substations of coal mines, iron mines, and copper mines, used to control and protect cable lines in mining areas, and control transformers or high-voltage motors; Power conversion, distribution, control functions. [0004] When the existing power distribution cabinets are in use, most of them have the function of ventilation ...
