Background technology
High-tension switch cabinet is for realizing electric power system generating, transmission of electricity, distribution, electric energy conversion and having consumed the electric equipment products that break-make, control or protection etc. act on.High-voltage switch gear manufacturing industry is the manufacturing important component part of power transmission and transforming equipment, occupies very important status in whole power industry.
The high-tension switch cabinet (killer switch cabinet) of domestic and international 6～40.5KV mainly contains fixed switching cabinet (fixing cabinet), middle or withdraw-type switch cabinet (handcart cabinet), gas-filled type cabinet (gas-filling cabinet) and solid insulation switch cabinet at present, and above-mentioned various high-tension switch cabinets respectively have pluses and minuses.
Fixing cabinet is first generation high-tension switch cabinet product, and its cabinet is that internal part all adopts and is fixedly connected with, and simple in structure, element is few, good heat dissipation, and busbar connects reliable, and stability is higher, and cabinet size is less and floor space is little; Need to detect maintenance but break down, need power-off because its mode being fixedly connected with causes needing whole circuit, and dismounting trouble, make the repair time of fixing cabinet long and long from the time of causing power failure, bring great inconvenience to transmission of electricity electricity consumption.
The problem existing in order to improve fixing cabinet, handcart switch cabinet has been adjusted the position of circuit breaker in cabinet, and circuit breaker and a car body are integrated into a handcart circuit breaker movably, when maintenance, can extract breaker portion out cabinet, changes and facilitates; But due to the requirement of clear distance between electric conductor, cabinet is large and supplementary insulation body is many compared with fixing for the size that makes handcart cabinet.Position according to circuit breaker in cabinet can be divided into middle-placed switch cabinet and remove cabinet; In these switch cubicles, the location of circuit breaker cart and locking device are all located at the bottom of handcart, are subject to the restriction of himself structure, and this class location and locking device are generally applicable to little current switch cabinet, can not resist larger electric power moment.Because when switch cubicle short circuit current reaches 50kA and when above, the electric power of generation is very large, and this electric power is created in the junction of handcart moving contact and switch cubicle fixed contact.Because electrodynamic action point is larger apart from handcart distance from bottom, therefore bottom handcart positioner easily produces larger moment relatively, and then handcart loose shift easily occurs, and causes dynamic and static contact to be thrown off.Middle truck cabinet, because plug is slidably connected unreliablely, causes contact heating, and its structure poor radiation, often because of the overheated accident such as ageing of insulation, blast that causes.So existing handcart location, locking mode are difficult to meet the requirement that the large electric current of switch cubicle, height cut-off.In order to promote the stability of handcart switch cabinet in combined floodgate closed-circuit working, prior art has the improvement about handcart fixed form and device in a large number, as Chinese patent application CN102983524 discloses a kind of breaker handcart of switch cabinet, comprise car body, car body head is provided with moving contact, and car body both sides are respectively equipped with location-plate; Location-plate is provided with the directive wheel suitable with the orbital groove of handcart positioner, and with the test position lockhole of handcart positioner and the suitable elasticity locking bar of working position lockhole.The disclosed positioner of this application and application thereof and breaker handcart of switch cabinet can to realize accurate guiding and the left and right of handcart spacing, and can meet the strong fix of handcart under diverse location state, the opplied moment that electric power produces can be effectively reduced, and then larger electric power can be overcome; But still cannot realize the stability identical or close with fixing cabinet; In addition the cabinet inner breaker of middle-placed switch cabinet generally adopts VS1 or VD4 vacuum circuit-breaker, and whether dynamic/static contact contraposition accurately cannot monitor, and the structure of contact box makes to be unfavorable for contact heat radiation, and insulation assembly is easily aging, and insulation breakdown discharge accident occurs.
