[0043] The beneficial technical effects of the fire-fighting electrical control cabinet of the embodiments of the present application are as follows:

[0044] The device adds the fire extinguishing assembly 6 and the fire spread prevention assembly 5. When the temperature in the cabinet abnormally rises, the temperature sensor 51 triggers the electric telescopic rod 52, which quickly closes the cabinet door through the push rod 53, sliding block and connecting rod 57 mechanism, reduces the oxygen entering, suppresses the spread of fire, avoids manual intervention delay, and realizes rapid response. In addition, through the direct connection pipe 62, PVC telescopic pipe 66 and hollow support 63, the carbon dioxide gas is transported to different heights in the cabinet, realizing full coverage fire extinguishing. The design of the multi-layer elements in the cabinet has higher fire extinguishing efficiency than the traditional manual spraying. In addition, the exhaust fan 2 can exhaust the high-temperature smoke or residual flammable gas in the cabinet, reducing the risk of reignition.

[0045] The above is only a preferred embodiment of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the application shall be included in the protection scope of the present application.
