Description

Full clad type three station isolation circuit breakers
Technical field
The utility model relates to the technical field of switch cubicle, particularly relates to one and to be arranged in switch cubicle and to be mainly applicable to 40.5KV(international standard) following full clad type three station isolation circuit breakers.
Background technology
Three station isolation circuit breakers comprise tri-station isolating switch, vacuum circuit-breaker and cable terminal.
Three-station, English is called for short 3PS, i.e. 3positionswitchgear.Three-station is usually used in fully closed combined electric unit (GIS) or compound electric apparatus (PASS), is not an independent product.Be usually used in XGN ring main unit.So-called three stations refer to three service positions: 1 is the closing position that isolated switch main fracture is connected, and 2 is isolated locations that main fracture separates, and 3 is earthing positions of ground side.Three-station is exactly the function incorporating isolating switch and earthed switch in fact, and come by a cutter, so just mechanical latching can be realized, prevent major loop charged conjunction ground cutter, because one a position, and can only not resemble traditional isolating switch cutter, operator is operator, ground cutter is ground cutter, just may go out misoperation between two cuttves.And tri-station isolating switch is a cutter, one is at a time unique the service position of cutter, and not being at main switch closing position, is exactly at isolated location or earthing position.In traditional GIS, isolating switch and earthed switch are two functional units, and use electrical interlock to control, present recent design uses tri-station isolating switch exactly, avoids the possibility of misoperation.
Vacuum circuit-breaker is gained the name because the dielectric of contact gap after its arc-extinguishing medium and arc extinguishing is all high vacuum; It has volume little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, apply comparatively universal in power distribution network.
Cable terminal is used to connection external cable, thus realizes conveying electricity.
Existing three station isolation circuit breakers can not realize entirely coated, and withstand voltage properties is poor, and electric equipment volume is comparatively large, and troublesome poeration, cannot meet the requirement of miniaturized all insulation, poor safety performance, more can not meet multiple occasion and use.
Usually sulphur hexafluoride (SF will be filled in existing three station isolation circuit breakers 6) gas, particularly to fill sulphur hexafluoride (SF in vacuum circuit-breaker 6) gas, sulphur hexafluoride (SF 6) there is good insulation property and arc extinction performance, be filled in vacuum circuit-breaker and can be played better insulation property and withstand voltage properties, operation of keeping the safety in production can be ensured, but sulphur hexafluoride (SF 6) gas chemistry is stablized, not easily decomposed in atmospheric environment, and sulphur hexafluoride (SF 6) gas can work the mischief to environment, causes greenhouse effect, existing sulphur hexafluoride (SF 6) gas mixes poisonous low sulfur fluoride usually, hydrogen fluoride, ten fluoridizes two sulphur gases, easily human body is damaged.
Tri-station isolating switch structure all relative complex on market, the three-station used in current electrical network is mainly assembled by imported equipments and parts, its complex structure, and volume is large, and cost is high, the poor accuracy of switch motion, poor reliability.
Existing tri-station isolating switch is connected with bus usually, and current bus is all outside exposed substantially, can not meet the requirement of all insulation, there is larger potential safety hazard, more can not meet multiple occasion and use.
Existing cable terminal vertically arranges output port usually, needs to bend, increase task difficulty, and affect the useful life of cable when causing cable to access.
