Technical field
The utility model relates to a kind of power system device, particularly relates to the load type insulating support in a kind of vacuum load switch Central Shanxi Plain.
Background technology
Present vacuum load switch divides three parts usually, comprises isolating switch part, vacuum lumen part and fuse and earthed switch part.As a kind of indoor AC vacuum on-load switch, be applicable to ring network power supply or terminal powered switch element in the distribution systems such as industrial and mineral, enterprise, residential quarters, school with high and low breaking capacity.
But traditional vacuum load switch its close/that brake separating mechanism and major loop leading-out terminal connect copper bar is too complicated, causes volume still bigger, the user designs power distribution cabinet and takes up room greatly sometimes, causes complete set of equipments cost excess waste.Its insulated leg also is only to have installed isolating switch and vacuum switch concentratedly, in the whole main conductive circuit, moistureproof, dustproof, insulation property, cut down the consumption of energy and aspects such as electric power that Short Circuit withstand causes all not good enough.Its switching-on mechanism particularly is not enough in the close a floodgate surge force intensity of anti-dynamic and thermal stability electric current in service of switch; Separating brake dropout parts connecting link is too various, and the fuse combined electric apparatus switch divides the time long admittedly, causes factors such as switch interrupting performance instability, causes more apparatus failure, increases the electric equipment maintenance cost.
Stationary contact head on the insulated leg in the past dress and copper mold insert etc. all be portion's piece installing of exposing on insulating support, owing to it can not effectively insulate, thus in use can be owing to the influence of electric arc etc., and shorten useful life of insulating support greatly.
Summary of the invention
For addressing the above problem, the utility model provides a kind of insulating support that makes that stationary contact head dress and copper mold insert can effectively insulate.
The utility model solves the technical scheme that its technical problem adopted:
A kind of load type insulating support; Comprise rack body; Rack body is provided with the top that is used to install isolation knife, is used to install the middle part of vacuum interrupter and the bottom of rack body; Be provided with stationary contact head dress on the top of rack body, the middle part of rack body is provided with inner chamber, and the top, the outside of inner chamber is provided with the copper mold insert; The stationary contact head is loaded onto and is provided with the buffered silica gel of fitting with stationary contact head dress, and around the last copper mold insert and top is respectively equipped with the silicon rubber cup that is used to protect the silica gel plug of copper mold insert and is covered on silica gel plug top.
Further as the improvement of the utility model technical scheme, the outside of inner chamber is provided with and is used for closed cavity and protective cover that can be for convenience detach, and protective cover is a translucent cover.
Further as the improvement of the utility model technical scheme, be provided with vacuum interrupter in the inner chamber, the bottom outside of inner chamber connects and is provided with fuse clips portion dress, and the bottom of the inherent vacuum interrupter of inner chamber also is provided with last fuse device folder portion and adorns being flexible coupling of connecting.
Further as the improvement of the utility model technical scheme, the bottom of rack body is provided with insulated support, and through being fixed with insulated support and the joining conducting copper mold insert down that is flexible coupling, following conducting copper mold insert is enclosed in the bottom of rack body admittedly.
The beneficial effect of the utility model: this load type insulating support is being arranged at can the fit buffered silica gel of stationary contact head dress of stationary contact head dress arranged outside on the rack body; And around last copper mold insert, reach the top and be respectively equipped with silica gel plug that is used to protect the copper mold insert and the silicon rubber cup that is covered on silica gel plug top; Can make stationary contact head dress and last copper mold insert effectively insulate to external world, thereby effectively prolong the useful life of insulating support.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model embodiment overall structure sketch map;
Fig. 2 is the utility model embodiment overall structure front schematic view.
Embodiment
With reference to Fig. 1, Fig. 2; The utility model is a kind of load type insulating support; Comprise rack body 1, rack body 1 is provided with the top that is used to install isolation knife, is used to install the middle part of vacuum interrupter and the bottom of rack body 1, is provided with the stationary contact head on the top of rack body 1 and adorns 2; The middle part of rack body 1 is provided with inner chamber 3; The top, the outside of said inner chamber 3 is provided with copper mold insert 4, and the stationary contact head is adorned 2 and is provided with the buffered silica gel 5 of adorning 2 applyings with the stationary contact head, and around the last copper mold insert 4 and top is respectively equipped with the silicon rubber cup 61 that is used to protect the silica gel plug 6 of copper mold insert 4 and is covered on silica gel plug 6 tops.
This load type insulating support is adorned can the fit buffered silica gel 5 of stationary contact head dress of 2 arranged outside being arranged at stationary contact head on the rack body; Around the last copper mold insert 4 and top is respectively equipped with the silicon rubber cup 61 that is used to protect the silica gel plug 6 of copper mold insert 4 and is covered on silica gel plug 6 tops; Can make the stationary contact head adorn 2 with the effectively insulation to external world of last copper mold insert 4, thereby effectively prolong useful life of insulating support.
As the utility model preferred embodiment, the outside of inner chamber 3 is provided with and is used for closed cavity 3 and protective cover 7 that can be for convenience detach, and protective cover 7 is a translucent cover.
