Background technology

High-tension switch cabinet is for realizing power system generating, transmission of electricity, distribution, electric energy conversion and playing break-make, control in consuming The electric equipment products of the effect such as system or protection.High-voltage switch gear manufacturing industry is the manufacturing important component part of power transmission and transforming equipment, whole Very important status is occupied in individual power industry.But chopper is whole switch cubicle key component, and the classification of switch cubicle Also the position in switch cubicle is relevant with chopper.

The high-tension switch cabinet (circuit breaker switch cabinet) of domestic and international 6～40.5KV mainly has fixed switching cabinet (fixing at present Cabinet), middle or withdraw-type switch cabinet (hands injured), inflated type cabinet (gas-filling cabinet) and solid insulation switch cabinet, above-mentioned various height The cabinet that compresses switch respectively has pluses and minuses.

Fixing cabinet is first generation high-tension switch cabinet product, its cabinet be internal part all using being fixedly connected, structure is simple, Element is few, good heat dissipation, and busbar connects reliability, and stability is higher, and cabinet size is less and floor space is little；But there is event Barrier needs Measuring error, because the mode that it is fixedly connected leads to need whole circuit to need power-off, and dismantles trouble, makes the inspection of fixing cabinet Repair time length and long from the time of causing power failure, bring great inconvenience to transmission of electricity electricity consumption.

In order to improve the problem that fixing cabinet exists, handcart switch cabinet have adjusted position in cabinet for the chopper, will break Road device and a car body are integrated into a moveable handcart circuit breaker, can extract breaker portion out cabinet during maintenance, and it is convenient to change； But the requirement of clear distance is so that the size of hands injured is big compared with fixing cabinet and ancillary insulator is many between due to electric conductor.According to chopper Position in cabinet can be divided into middle-placed switch cabinet and remove cabinet；In these switch cubicles, the positioning of circuit breaker cart and locking device are all provided with In the bottom of handcart, limited by its own structure, this kind of positioning and locking device apply in general to low current switch cabinet it is impossible to Resist larger electric power moment.Because when switch cubicle short circuit current reach 50kA and above when, the electric power of generation is very big, And this electric power produces in the junction of handcart moving contact and switch cabinet static contact.Due to electrodynamic action point away from handcart bottom away from From larger, the therefore opposing floor portion handcart positioner easily larger moment of generation, and then easy generation handcart loose shift, lead to Dynamic and static contact disengages.Middle truck cabinet, because plug is slidably connected unreliable, leads to contact heating, and its structure Poor radiation, often because of accidents such as excessively thermally-induced insulation ag(e)ing, blasts.So existing handcart positioning, locking mode are difficult to satisfaction and open Close cabinet high current, the high requirement cut-off.In order to lift stability in combined floodgate closed-circuit working for the handcart switch cabinet, prior art has A large amount of improvement with regard to handcart fixed form and device, such as Chinese patent application CN 102983524 disclose a kind of switch cubicle and break Road device handcart, including car body, car body head is provided with moving contact, and car body is respectively provided on two sides with location-plate；Location-plate is provided with and handss The directive wheel that the orbital groove of car positioner is adapted, and the test position lockhole with handcart positioner and working position lockhole The elastic locking bar being adapted.Positioner disclosed in this application and its breaker handcart of switch cabinet obtained by application are capable of handss The accurate guiding of car and left and right are spacing, and can meet the strong fix of handcart under diverse location state, can effectively reduce electric power The opplied moment producing, and then larger electric power can be overcome；But still the stability same or like with fixing cabinet cannot be realized Energy；In addition the cabinet inner breaker of middle-placed switch cabinet typically adopts VS1 or VD4 vacuum circuit breaker, and dynamic/static contact para-position accurately whether cannot Monitoring, the structure of contact box makes to be unfavorable for that contact radiates, insulation assembly is easily aging, and insulation breakdown discharge accident occurs.
