Description
Technical field
The utility model relates to the switch electricity cabinet of electric power, especially a kind of loading switch cabinet.
Background technology
On-load switch closes under the overload condition that can specify at normal galvanic circle conditioned disjunction, carries and drop-out current, also can press the switchgear of official hour loaded current under the galvanic circle condition (such as short circuit) of exception.
The insulating properties of existing its housing of on-load switch and anti-pollution performance need to be improved further, and when the inside arcing fault produced, likely can cause case fragmentation, easily be damaged to operator or destroy other parts; And the effect of clutch structure of interlocking in middle on-load switch is exactly open a sluice gate at operation switching action bars or close a floodgate, on-load switch action bars is in and engages or disconnect, thus ensureing under "on" position, operating personnel cannot make operation to on-load switch action bars, ensure safety.But current vacuum load switch, interlocking clutch structure more complicated wherein, unreasonable structure, does not reach good clutch effect.
Therefore, the utility model proposes a kind of a kind of loading switch cabinet of improvement at this.
Utility model content
For the defect existed in prior art, the purpose of this utility model is just to provide a kind of loading switch cabinet, and it prevents electric arc from damaging, and can ensure a kind of loading switch cabinet of operator safety under "on" position.
The utility model solves the technical scheme that its technical problem adopts: a kind of loading switch cabinet, comprise cabinet, described cabinet is become with the low-pressure chamber group being positioned at main cabinet top by main cabinet, it is characterized in that: in described main cabinet, be provided with contact body and transducer, described transducer is positioned at the below of contact body, it is connected with described contact body by wire, described contact body is the insulation shell of vacuum, shell is filled with the nitrogen gas of insulation, and the coiling end at contact body top scribbles the thick anti-electric segment of 0.2-0.5mm; Be provided with on-load switch mechanism and central interlock mechanism in described low-pressure chamber cabinet, described on-load switch mechanism one end is connected with described contact body, and the other end is connected with described central interlock mechanism; Described on-load switch mechanism is primarily of fork, drive link, contact block composition, fork is fixedly installed on low-pressure chamber cashier's office in a shop, contact block is arranged on low-pressure chamber cashier's office in a shop rotationally by drive link, the two ends of fork are flexibly connected with drive link and contact block respectively, and under the promotion of fork, make contact block be separated with section before and after contact body; Described central interlock mechanism is connected with on-load switch mechanism by longitudinal slide member.
Adopting above technical scheme, the anti-electric segment of the utility model by establishing 0.2-0.5mm thick, when the inside arcing fault produced, being unlikely to be damaged to operator or to destroy other parts; And central interlock mechanism is connected with on-load switch mechanism by longitudinal slide member, the fork of on-load switch mechanism is fixedly installed on low-pressure chamber cashier's office in a shop, contact block is arranged on low-pressure chamber cashier's office in a shop rotationally by drive link, the two ends of fork are flexibly connected with drive link and contact block respectively, and under the promotion of fork, make contact block be separated with section before and after contact body, operator safety under "on" position can better be ensure that, and simple to operate and very, reliable and stable.
Described main cabinet is fabricated structure, and it is threaded connection by left plate, right plate, front side board, back side panel, upper sealing plate and cover plate and forms.
Adopt above technical scheme, cabinet body structure of the present utility model is more simple, changes and repairs conveniently.
