Description
Technical field
The utility model relates to a kind of isolating switch.
Background technology
Current power distribution system equipment is generally made up of isolating switch, vacuum interrupter, earthed switch etc., with bus, these autonomous devices are connected to form electric power system, its isolating switch, earthed switch be generally adopt guillotine type or rotary come circuit and connection and cut-off, dielectric can be divided into air, oil, SF6 sulfur hexafluoride gas etc.Best with SF6 sulphur hexafluoride performance, but SF6 sulfur hexafluoride gas is also one of six kinds of greenhouse gases of generally acknowledging in the world, and also can produce toxic gas when electric current cut-offs, manufacturing and in maintenance process, even also endangering that it arrives the life of people.With the apparatus insulated poor-performing of air as insulated switch, the equipment volume therefore produced is comparatively large, and floor space is large, and by the impact of environment for use, the factors of instability are more, and are not suitable for for outdoor environment.Ring main unit and switch cubicle are the primary power source power supply units using this this equipment combination, and primary power source to this equipment, is transported to user through isolating switch, vacuum interrupter or combined electrical apparatus through cable transmission.Earthed switch side ensures personal safety use for during maintenance, isolating switch also have upper isolation and lower isolation point, be equally all safeguard protection effect.Because this several switch has respective volume, total volume that combines is comparatively large, and the volume of whole equipment is increased, and manufacturing cost improves.Because equipment separate connection loop increases, total loop resistance is increased, and the electric energy that system consumes on the device is also without many.Isolating switch, the fracture of earthed switch in these dielectrics are apart from relatively large in addition, make the size of whole switch also become large.
Ring main unit is widely used in recent years, is because ring main unit structure is simple, reliable and safety, and maintenance capacity is very little, and operating cost is low.The ring main unit of current manufacture mainly contains gas-insulated, and based on SF6 sulfur hexafluoride gas, some is the gas of SF6 sulphur hexafluoride and other gas and vapor permeation.The research and development of solid insulation ring main unit in recent years and application are obtaining the attention of each side, also have made some progress, be generally by coated for the rear solid dielectric insulations of combination such as vacuum interrupter, isolating switch, earthed switch, the main bus bar one that is packaged into, but the insulation of the fracture of isolating switch, earthed switch is still use air insulation.The length simultaneously operating the insulated tension pole of vacuum interrupter also has influence on the size of this product, makes physical dimension still larger like this.Therefore designed ring main unit size is comparatively large, particularly in the impact of short transverse.Ring main unit is generally used for avenue, residential quarter, and large size floor space is large, and particularly tall and big size becomes a kind of visual pollution, makes troubles to the trip of people.Fewer and feweri in spendable soil, the environmental consciousness of people is more and more stronger, so more needs us to provide the equipment for power transmission and distribution that a kind of volume is less.
The defect that existing isolating switch exists: complex structure, to take submission larger.
Summary of the invention
