Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electrical appliances, in particular to a novel safe and reliable high-voltage switch cabinet. Background Art

[0002] As the name implies, high-voltage switchgear is equipment for connecting high-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers to low-voltage cabinets, and then to distribution boxes for various electricity users. Inside, there are nothing more than some protective devices such as switches and circuit breakers assembled into one electrical device. In the hot and humid summer weather, when the equipment in the switchgear is running, a lot of heat will be generated inside, and the air outside the cabinet will enter the cabinet. Due to the high water content of the air entering the cabinet, the humid gas in the air will enter the interior of the high-voltage switchgear through the heat dissipation port, which can easily reduce the service life of the components in the cabinet, causing great inconvenience to the users.

[0003] After searching, the Chinese patent announcement number: CN214478511U discloses a new type of safe and reliable high-voltage switch cabinet including a cabinet, a fire extinguishing mechanism and a heat dissipation mechanism, wherein the fire extinguishing mechanism is arranged on the cabinet, and the heat dissipation mechanism is arranged on the cabinet. The fire extinguishing mechanism includes a dry powder fire extinguishing storage box, a fire detector and an alarm, and the dry powder fire extinguishing storage box is installed on the top of the cabinet. Suction pumps are installed on the left and right sides of the top of the inner wall of the cabinet.
