The high-voltage switchgear is used in Shanghai Eaton general equipment network cabinet (HXGN type) and so on.

[0003] When the existing high-voltage switchgear is in use, there is no mechanism to monitor the burning fire. Therefore, once a fire occurs, personnel cannot rush to extinguish the fire immediately, and there is no mechanism to extinguish the fire immediately. This will cause the high-voltage switchgear and surrounding objects to be burned and damaged to a great extent.

[0004] The existing Chinese patent with announcement number CN220570093U discloses a combined high-voltage switch cabinet, which relates to the technical field of high-voltage switch cabinets, including a cabinet, a base is provided on the inner bottom surface of the cabinet, a carbon dioxide storage tank is provided on the top of the base, a connecting pipe is provided on one side of the carbon dioxide storage tank, and a discharge pipe is provided at one end of the connecting pipe. The utility model can detect the internal temperature and gas smoke of the device by using a temperature detector and a smoke detector. In case of fire, the controller can alarm the personnel's mobile phone terminal, open the electromagnetic valve, and let the carbon dioxide inside the carbon dioxide storage tank be discharged through the connecting pipe, the discharge pipe and the nozzle, so that the internal part of the device can be extinguished, so that the personnel can quickly know the fire situation, and can also quickly extinguish the fire to reduce the degree of combustion damage.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the carbon dioxide storage tank of the device is installed inside the high-voltage switch cabinet, which occupies a relatively large installation space of the high-voltage switch cabinet, and the position of the nozzle is fixed, so that the carbon dioxide spraying range is fixed, and fire extinguishing cannot be carried out relatively comprehensively, and improvement is needed; therefore, a high-voltage switch cabinet is proposed to address the above problems.
