Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to an air-insulated ring network switch device. Background Art

[0002] Ring main unit is a set of electrical equipment with high voltage switchgear installed in a steel plate metal cabinet or made into an assembled interval ring main unit.

It is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers.

[0003] Among them, air-insulated ring main switchgear is a type of ring main cabinet. Since a large number of electrical components are installed inside the air-insulated ring main switchgear, a large amount of heat will be generated during operation, so there is a hidden danger of fire. Therefore, it is necessary to install a fire monitoring and extinguishing device to extinguish the initial fire in time to avoid the expansion of losses.

[0004] The Chinese utility model patent with patent application number 202121040390.7 records an AC metal normal pressure sealed air insulated ring network switchgear, which monitors the fire through a smoke alarm. When a fire occurs, the insulating fire extinguishing agent in the fire extinguisher tank is sprayed out through the nozzle to extinguish the fire and suppress the spread of the fire. However, the nozzle in the above-mentioned equipment is located at the top of the cabinet cavity, and there are many kinds of components in the cabinet. The components on the upper side may block the components on the lower side. At this time, if the components on the lower side catch fire, the insulating fire extinguishing agent may not be able to fall on the fire point in time and effectively due to obstruction, resulting in the fire cannot be controlled and extinguished in time, and there is a safety hazard of fire expansion.
