Description
Technical field
The utility model relates to a kind of killer switch cabinet, particularly a kind of air-insulated compact circuit breaker switch cubicle of employing for exchanging the distribution network.
Background technology
Economic development along with society, the continuous acceleration of urbanization process, distribution network construction has been proposed more requirement, a large amount of newly-built or suffered construction area restrictions of enlarging urban distribution network power transformation, require the floor space of power distribution network electric device further to reduce, intensive utilization land resource, raising soil utilize intensity.In order to adapt to distribution substation to the compact requirement of electric device, the cabinet of various compacts continues to bring out.And its great technological break-through has been adopted sulphur hexafluoride SF before being mainly derived from 20 years
6The application of gas insulation technology on middle voltage distribution networks compact equipment.SF
6As a kind of insulating gas, remarkable insulation property are arranged, excellent cooling electric arc property.In the application of electric equipment, can significantly reduce the size of equipment, improve apparatus insulated reliability, so SF
6The insulated switch cabinet is the extensive use electricity market once.
Chinese patent literature CN2766426Y discloses a kind of box-type sulfur hexafluoride switch cabinet on 03 22nd, 2006, by cabinet, major loop switch and charged annex chamber, four parts in operating mechanism chamber and cable vault form, major loop switch and charged annex chamber are seal cases, have been full of SF in the seal case
6Insulating gas.
