Description
Technical field
The utility model relates to a kind of parts of gas insulated metal enclosed swit chgear equipment, specifically the novel elastic quiet arc contact of isolating switch in the combined electrical apparatus.
Background technology
In China's immediate plan, electricity market is also with sustainable development, and the scale of electricity needs and power station power grid construction also enlarges day by day.In China, because the restriction of State owned land resource, the layout in traditional open type power station is fewer and feweri, and the more and more concentrated construction in incompatibility power station, and gas insulated metal enclosed swit chgear then adapts to the concentrated construction in power station, can effectively save the soil.Therefore, in recent years, gas insulated metal enclosed swit chgear was developed on a large scale in China.In the gas insulated metal enclosed swit chgear, mainly comprise circuit breaker and isolation earthing switch etc.Wherein, isolating switch mainly plays maintenance and isolates, switches bus, deciliter idler circuit with segmentation in the line, and automatic isolation fast waits effect, and its importance is very big.When doing the transmitting current of isolation switch switching bus bar test, because current ratio is bigger, can cause electric arc, therefore the scaling loss contact, during design, needs to increase quiet arc contact part easily.The design of quiet arc contact in the past generally all is positioned at the end of conductive contact blade, its position can not change, and the outside need add radome and come uniform electric field to distribute, for fear of electrical arc erosion radome opening, meeting is bigger with this open design, and electric field just is difficult to accomplish even distribution; In addition, when doing the test of folding bus switching current,, often also can cause the scaling loss of radome, influence the Electric Field Distribution between fracture, and then cause that the insulating capacity between fracture descends owing to reasons such as arcings.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of rational in infrastructure that the utility model provides, and Electric Field Distribution is even, and is safe, reliable, can prevent folding bus switching current when test novel elastic quiet arc contact to the radome scaling loss.
The technical solution adopted in the utility model is: a kind of novel elastic quiet arc contact, comprise arcing contact, also comprise conductive sleeve and elastic device, described arcing contact is arranged on the opening part of radome and is connected with telescopic conductive sleeve, the rear portion of conductive sleeve is provided with elastic device, and the rear portion of conductive sleeve is connected with housing by fixed mount.
Described elastic device is a spiral compression spring.
Because the utility model is arranged on arcing contact on the telescopic conductive sleeve, the rear portion of conductive sleeve is provided with elastic device again, moving contact moves to the fixed contact direction, behind the zone in moving contact enters radome, moving contact promotes arcing contact and moves together, under the effect of elastic device, moving contact contacts all the time with arcing contact, discharge is carried out between moving contact and arcing contact fully, can not have influence on radome, avoid radome by scaling loss, uniform electric field distributes, improve insulation level, thereby improved the overall performance of gas insulated metal enclosed swit chgear.

Fig. 1 is a schematic diagram of the present utility model
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, the technical solution adopted in the utility model is: a kind of novel elastic quiet arc contact, comprise arcing contact 1, conductive sleeve 2 and elastic device 3, described arcing contact 1 is arranged on the opening part of radome 4 and is connected with telescopic conductive sleeve 2, fixed contact 6 is arranged on the outside of conductive sleeve 2, conductive sleeve 2 can drive arcing contact 1 and move horizontally in fixed contact 6, the rear portion of conductive sleeve 2 is provided with elastic device 3, and the rear portion of conductive sleeve 2 is connected with housing by fixed mount 5.Elastic device 3 in the present embodiment is a spiral compression spring.
When isolating switch closed a floodgate, moving contact travelled forward, and promptly moved to fixed contact 6 directions, when being close to certain distance, discharge between the moving arcing contact of moving contact front end and the arcing contact 1, this moment, electric arc occurred on moving arcing contact and the arcing contact 1, can scaling loss radome 4.Moving arcing contact is with after arcing contact 1 contacts, and moving contact promotes arcing contact 1 to be continued to move forward together, and the spring of conductive sleeve 2 inside begins compression, and after isolating switch was incorporated into the position fully, moving contact began to contact conduction with fixed contact 6, finishes the through-flow of big electric current.When the isolating switch separating brake; moving contact moves backward; promptly to direction motion away from fixed contact 6; conductive sleeve 2 drives arcing contact 1 and follows moving contact and move together under the effect of elastic device 3; arcing contact 1 keeps in touch with the moving arcing contact of moving contact end all the time; leave radome 4 fully up to moving arcing contact; discharge is carried out between moving arcing contact and arcing contact 1 fully; can not have influence on radome 4; protected radome 4 not by electrical arc erosion; guaranteed that electric field evenly distributes, improved insulation level, thereby improved the overall performance of gas insulated metal enclosed swit chgear.
This shows, when the utility model can prevent the opening-closing bus switching current to the radome scaling loss, Have rational in infrastructure, the characteristics such as Electric Field Distribution is even, and is safe, reliable.
