Description
Technical field
The utility model relates to a kind of GIS combined electrical apparatus technical field, and specifically one is applied to the horizontal combined electrical apparatus of 252kV.
Background technology
Combined electrical apparatus, claim again Cubicle Gas-Insulated Switchgear, it is to be directly linked to together by elements such as circuit breaker, isolating switch, earthed switch, main bus bars, and is all enclosed in the metal shell of ground connection, fills using the SF6 gas of certain pressure as insulation and arc-extinguishing medium in shell.Earthed switch in the horizontal combined electrical apparatus of 252kV at present, normally, with being combined into one of isolating switch structure, another is the one group of closure of connecting on bus, and earthed switch is arranged separately.Earthed switch in above two kinds of structures and the housing of circuit breaker be not in same air chamber, be that earthed switch and circuit breaker need not same housings, the parts that said structure uses are more, take up room larger, the cost of civil engineering aspect, power station increases, and has increased the workload of parts maintenance simultaneously.Therefore, in the today of being becoming tight soil space resource day, how to provide a kind of installation site rational earthed switch, make combined electrical apparatus connection and reasonable arrangement, make full use of component space, reduced volume, becomes the current technical issues that need to address.
Summary of the invention
The utility model provides a kind of reasonable structural arrangement in order to overcome above-mentioned defect, and the horizontal combined electrical apparatus of little 252kV takes up room.
The technical solution adopted in the utility model is: the horizontal combined electrical apparatus of a kind of 252kV, comprise circuit breaker, arc control device, earthed switch and operating mechanism, the housing of circuit breaker is horizontally set, arc control device are horizontally installed on enclosure interior, earthed switch is connected with operating mechanism, it is characterized in that: in the bottom of housing, be provided with and pull out mouth near leftward position, pull out and on mouth, be provided with abutted flange, earthed switch is connected to the bottom of this abutted flange, operating mechanism is arranged on the left side of earthed switch, moving contact on earthed switch extend into enclosure interior through abutted flange, the fixed contact of earthed switch is arranged on the bottom of arc control device and corresponding to moving contact top.
The utility model has been installed to traditional earthed switch being arranged on isolating switch the bottom of Shell of circuit breaker, and the moving contact on earthed switch is extend into enclosure interior, simultaneously, the fixed contact of earthed switch is arranged on to arc control device bottom the top corresponding to moving contact, under the effect of operating mechanism, drive the moving contact of earthed switch to move up and down, thereby be grounded separating brake and the combined floodgate of switch, the installation site of this earthed switch effectively utilizes lower housing portion space, make layout more reasonable, reduce the volume of isolating switch part branch, thereby reduce the volume of whole combined electrical apparatus, and realize earthed switch and circuit breaker and shared a housing, share an air chamber, reduce amount of parts, be convenient to the maintenance arranging.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise circuit breaker 1, arc control device 2, earthed switch 4 and operating mechanism 7 etc., the housing 3 of circuit breaker 1 is horizontally set, arc control device 2 are horizontally installed on housing 3 inside, housing 3 is arranged on underframe conventionally, and earthed switch 4 is connected with operating mechanism 7.Be provided with and pull out mouth in the bottom of housing 3, close leftward position, pull out mouth and claim again flanged pipe, the circular body arranging downwards in housing 3 bottoms, pulls out and on mouth, is provided with abutted flange, abutted flange i.e. the ring flange for connecting, and this ring flange is arranged on the bottom of pulling out mouth.Earthed switch 4 is connected to the bottom of abutted flange, and operating mechanism 7 is arranged on the left side of earthed switch 4.Moving contact 5 on earthed switch 4 extend into housing 3 inside through abutted flange, earthed switch 4 and this abutted flange are for being tightly connected, earthed switch 4 and abutted flange, pull out mouthful and housing 3 forms a sealed air chamber, the fixed contact 6 of earthed switch 4 is arranged on the bottom of arc control device 2 and corresponding to moving contact 5 tops.The installation site of fixed contact 6 has effectively utilized the idle space of housing 3 inside, and earthed switch 4 is arranged on to bottom at the bottom of shell, makes layout more reasonable.
When the utility model uses, circuit breaker 1 operating mechanism 7 drives circuit breaker 1 moving contact 5 and moving arcing contact to do the motion of horizontal direction, realize the divide-shut brake of combined electrical apparatus, while needing ground state, the operating mechanism 7 of earthed switch 4 drives the moving contact 5 in earthed switch 4 to do vertical direction motion, make moving contact 5 contact or disconnect with the fixed contact 6 of its top, thereby be grounded combined floodgate or the separating brake of switch 4.
Because the utility model has been installed to earthed switch 4 bottom of circuit breaker 1 housing 3, and make the moving contact 5 on earthed switch 4 extend into housing 3 inside, simultaneously, the fixed contact of earthed switch 46 is arranged on to arc control device 2 bottoms the top corresponding to moving contact 5, under the effect of operating mechanism 7, drive the moving contact 5 of earthed switch 4 to move up and down, thereby be grounded separating brake and the combined floodgate of switch 4, the installation site of this earthed switch 4 effectively utilizes housing 3 lower space, make layout more reasonable, reduce the volume of isolating switch part branch, thereby reduce the volume of whole combined electrical apparatus, and the fixed contact 6 of earthed switch 4 is installed on the bottom of arc control device 2, realize earthed switch 4 and shared a housing 3 with circuit breaker 1, share an air chamber, reduce amount of parts, be convenient to the maintenance arranging.
The utlity model has reasonable structural arrangement, little feature takes up room.
