A kind of secret switch cabinet

Technical field

It is to be related to a kind of secret switch cabinet, more particularly to one specifically the present invention relates to a kind of power distribution cabinet Sealed high-tension switch cabinet is planted, belongs to technical field of electric equipment.

Background technology

High-tension switch cabinet is to be used to realize in power system generating, transmission of electricity, distribution, electric energy conversion and consumption to play break-make, control The electric equipment products of the effect such as system or protection.High-voltage switch gear manufacturing industry is the manufacturing important component of power transmission and transforming equipment, whole Occupy very important status in individual power industry.

Current domestic and international 6~40.5KV high-tension switch cabinet (circuit breaker switch cabinet) mainly has fixed switching cabinet (fixed Cabinet), middle or withdraw-type switch cabinet (hands injured), inflatable cabinet (gas-filling cabinet) and solid insulation switch cabinet, above-mentioned various height The cabinet that compresses switch respectively has advantage and disadvantage.

Fixation cabinet is first generation high-tension switch cabinet product, and its cabinet is that internal part use is fixedly connected, simple in construction, Element is few, good heat dissipation, and busbar connection is reliable, and stability is higher, and cabinet size is smaller and floor space is small；But generation event Barrier needs Measuring error, because its mode being fixedly connected causes to need whole circuit to need power-off, and dismounting trouble, makes the inspection for fixing cabinet Repair time length and from causing power off time long, great inconvenience is brought to transmission of electricity electricity consumption.

In order to improve the problem of fixed cabinet is present, handcart switch cabinet have adjusted position of the breaker in cabinet, will be disconnected Road device and a car body are integrated into a moveable handcart circuit breaker, and breaker portion can be extracted out to cabinet during maintenance, change convenient； But due to the requirement of clear distance between electric conductor so that the size of hands injured is big compared with fixed cabinet and ancillary insulator is more.According to breaker Position in cabinet can be divided into middle-placed switch cabinet and remove cabinet；The positioning of circuit breaker cart and locking device are all provided with these switch cubicles 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 torque.Because when switch cubicle short circuit current flow reaches 50kA and the above, the electric power of generation is very big, And the electric power produces the junction in handcart moving contact and switch cabinet static contact.Due to electrodynamic action point away from handcart bottom away from From larger, therefore opposing floor portion handcart positioner easily produces larger torque, and then easily occurs handcart loose shift, causes Dynamic and static contact is disengaged.Middle truck cabinet, because a plug is slidably connected unreliable, causes 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 that satisfaction is opened Close cabinet high current, the high requirement cut-off.In order to lift stability of the handcart switch cabinet in combined floodgate closed-circuit working, prior art has The largely improvement on handcart fixed form and device, such as Chinese patent application CN 102983524 discloses a kind of switch cubicle and broken Road device handcart, including car body, car body head are provided with moving contact, and car body both sides are respectively equipped with location-plate；Location-plate is provided with and hand The directive wheel that the orbital groove of car positioner is adapted, and experiment position lockhole and working position lockhole with handcart positioner The elastic locking bar being adapted.Breaker handcart of switch cabinet obtained by positioner disclosed in this application and its application can realize hand 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 of generation, and then larger electric power can be overcome；But still the stability same or like with fixed cabinet can not be realized Energy；In addition the cabinet inner breaker of middle-placed switch cabinet typically uses VS1 or VD4 vacuum circuit breakers, and whether accurate dynamic/static contact contraposition is can not Monitoring, the structure of contact box to be unfavorable for contact radiating, the easy aging of insulation assembly, generation insulation breakdown discharge accident.
