The switch cabinet is an electrical device, is used for providing installation and fixation for various electrical appliances, and is mainly used for opening and closing, controlling and protecting the electrical device in the power generation, power transmission, power distribution and electric energy conversion processes in an electric power system. After the switch cabinet operates for a long time, the electronic elements inside the switch cabinet lead to the increase of the contact resistance of the diversion position due to aging, oxidation or operation vibration, a large amount of heat is generated, if the heat can not be dissipated through the radiating holes of the switch cabinet, the contact resistance can be aggravated along with the accumulation of time, vicious circle is formed, disasters such as electric arcs or combustion occur, and huge potential safety hazards and economic loss are brought. Therefore, safety protection of the switchgear is of great importance in the operation of electric power. The safety protection of the switch cabinet mainly prevents high temperature and combustion, ensures normal operation of the switch, or avoids other equipment from being damaged when partial equipment breaks down. However, because the electrical components in the switch cabinet are special, mainly wires and cables, if the switch cabinet is ignited and then is used for extinguishing fire, the insulation performance of electrical equipment can be reduced, and nearby fire fighting personnel can be endangered. Meanwhile, the distance between the switch cabinets is small, and after any cabinet body is on fire, the high temperature of the switch cabinet can be rapidly transmitted to the adjacent cabinet bodies, so that the adjacent cabinet bodies are on fire.
the medium pipe network type fire extinguishing system and the suspension type fire extinguishing system of the high-voltage transformer substation are difficult to deploy, and the full-flooding cabinet type fire extinguishing system is usually used as a fire safety protection measure, but the fixed-point fire extinguishing aiming at the switch cabinet cannot be realized, so that the fire extinguishing and cooling efficiency is low.
in summary, the prior art lacks a targeted fire extinguishing method suitable for high-voltage switch cabinets.

Wherein the manual start is: the serial number and the temperature state of the switch cabinet are transmitted to a monitoring terminal through an Internet of things module, and a worker can control a clean gas fire extinguishing and spraying device of any switch cabinet body in a remote control mode to realize fire extinguishing and cooling at any fixed point;
wherein the automatic start is: after the alarm is triggered, the preset clean gas fire extinguishing spraying device is directly started to extinguish fire according to the position information of the cabinet body.
the further technical scheme is that the alarm is an acousto-optic alarm.
the further technical scheme is that the three clean gas fire extinguishing and spraying devices in the step S20 are respectively placed in the high-voltage switch cabinet area, the cable channel area at the bottom of the adjacent cabinet body and the underground cable area, and are used for extinguishing fire in the cabinet, spraying the cable, and extinguishing fire for the cable channel at the bottom of the adjacent cabinet body at the same time.
the invention has the following advantages:
(1) The subareas are characterized by fire disasters of the high-pressure chamber, and the fire ignition point is mainly in the cabinet body, so that a fire extinguishing area in the cabinet body is arranged to extinguish a fire source from the source;
(2) numbering the high-voltage indoor cabinet body, recording position and adjacent information, realizing network structured fire extinguishing and cooling implementation, and controlling fire behavior;
(3) The air storage tank of the fire extinguishing sprinkler is arranged in the square cable channel and is easy to replace and overhaul;
(4) the spray head is small in size, the normal mechanical linkage device action in the cabinet body cannot be influenced, meanwhile, clean gas can quickly fill the cabinet body, open fire can be extinguished, the temperature is reduced, and quick repair of maintainers is facilitated;
(5) Two-stage fire extinguishing mode, warning is realized and whether need put out a fire is judged by staff in the one-stage, can realize the fixed point simultaneously and put out a fire, realizes the rational distribution resources of putting out a fire. The secondary automatic fire extinguishing can quickly and effectively control the fire;
(6) the starting is rapid, and the fire extinguishing time is short;
(7) The clean gas fire extinguishing agent used by the invention is a green environment-friendly fire extinguishing agent such as perfluorohexanone, bromotrifluoropropenyl and the like, and has the advantages of excellent environment-friendly performance, high fire extinguishing efficiency, large safety margin, no electricity conduction, no damage to equipment and the like.
