Description
Technical field
The present invention relates to be a kind of distribution line and distribution transformer primary side as protection with carry out equipment throwing, cut the outdoor all insulation expulsion fuse of the use of operation, belong to the protective switch of the short circuit technical field of distribution line and distribution transformer.
Background technology
In power distribution network, more than 98% user uses fuse switch at present.The type fuse exists insufficiency, and protective value is poor, temperature rise, and break performance is low, electric and Mechanical Contact face is little, antifouling, antitheft, and anti-fault-free comes off, and anti-operation is dangerous, combined floodgate success rate, circuit operation ratio, the problem of the aspects such as arc extinguishing.Even selecting of fuse, also often there is substandard product; certain customers even replace fuse with copper wire, aluminum steel; in addition the own inherent characteristic of fuse; fuse can not normally be protected and coordinate with prime switchgear; while often occurring because of user side fault, expand the accident of power failure range, meanwhile, during a line failure; investigation fail operation is also very difficult, is unfavorable for the operational management of power distribution network.Although can select automatic circuit to substitute the security reliability that fuse switch improves power supply to power consumption is large with the important user of load, most of user is difficult to accept this scheme because automatic circuit is expensive.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists; and provide a kind of easy to operate, can be suitable for various severe environmental conditions, stable performance, be mainly used in 10KV supply line and electric equipment gamut, comprise the outdoor all insulation expulsion fuse of overload and short trouble protection.
The object of the invention is to complete by following technical solution, it includes an insulator, the cartridge fuse that upper and lower side is connected with respectively electrode is installed in insulator, upper end electrode is connected to the upper outlet lead-in wire being connected on distribution line, and lower end electrode is connected to the lower outlet lead-in wire that is connected to transformer side; The bottom of insulator disposes a dustproof seal cover.
One-body molded in lead outlet on the upper end of described insulator have a rubber seal on, and described upper outlet lead-in wire picks out from the centre of upper rubber seal; On the lower sides of described insulator, be horizontally arranged with lower lead outlet, and one-body moldedly in this lower lead outlet have a rubber seal, described lower outlet lead-in wire centre of rubber seal from this picks out.
Described insulator stage casing is horizontally arranged with one for fuse being installed to the installation anchor ear on gold utensil.
That the present invention has is easy to operate, can be suitable for the features such as various severe environmental conditions, stable performance, is mainly used in 10KV supply line and electric equipment gamut, comprises overload and short trouble protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, outdoor all insulation expulsion fuse of the present invention, it includes an insulator 1, the cartridge fuse 2 that upper and lower side is connected with respectively electrode is installed in insulator 1, upper end electrode 3 is connected to the upper outlet lead-in wire 4 being connected on distribution line, and lower end electrode 5 is connected to the lower outlet lead-in wire 6 that is connected to transformer side; The bottom of insulator 1 disposes a dustproof seal cover 7.
In order to form a good insulation and sealed environment, the present invention is one-body molded in lead outlet on the upper end of described insulator 1 rubber seal 8 on, and described upper outlet lead-in wire 4 picks out from the centre of upper rubber seal 8; On the lower sides of described insulator 1, be horizontally arranged with lower lead outlet, and one-body moldedly in this lower lead outlet have a rubber seal 9, described lower outlet lead-in wire 6 centre of rubber seal 9 from this picks out.
Insulator of the present invention 1 stage casing is horizontally arranged with one for fuse being installed to the installation anchor ear 10 on gold utensil.
All insulation expulsion fuse of the present invention, it has following technical advantage:
1), body adopts integrated structure, outside charging position is not exposed to, compares fuse switch, can greatly improve insulation property, also can relative decrease installing insulating distance, be conducive to install and use in the position of limited space;
2) cartridge fuse and charged position are accomplished completely built-inly, and charged like this position is just difficult for occurring filthy, can prevent that the insulation resistance causing due to filth from declining;
3) charging position is built-in, and electrode is difficult for getting rusty, and there will not be traditional fuse switch because the environmental factor such as rain, make moist causes electrode rust extremely, causes and the adverse consequences such as can not cut-off;
4) structural shape possesses acid rain preventing, and anti-salt dirt waits the corrosion of mal-condition to electrode, possesses extremely strong weatherability, can be applied in steadily in the long term in the environmental condition rugged environments such as coastal and industrial area;
5) can reliably protecting on all-sealed fuse structure fuse, prevent be similar to traditional fuse switch cartridge fuse because drenching with rain, make moist, may expand the fuse causing after sunshine by force in addition and be pulled off, cause the accident of during accidental power failure.
6) fuse outlet adopts the integrally formed structure of rubber, can effectively prevent dust pollution, salt dirt etc. like this, and reinforced insulation fail safe, guarantees long-term stability;
7) protected cut-out, after fuse failure, can be washed lower seal lid its part is stretched out outside insulator open, with indication fuse, fuses;
8) protected cut-out top and the bottom electrode adopts advanced configuration technique, stable closes, good arc extinction performance high-quality security performance.Can adopt petal type contact, advanced person's slit arc quenching method, in the time of can guaranteeing that the slit of electric arc between arc-extinguishing stick and expulsion tube extends, arc-extinguishing stick and expulsion tube can produce arc extinguishing gas, blow out electric arc, and security performance is high;
9) adopt the fuse (import fuse is better) with good fusing curve, can guarantee fuse performance, prevent that the fuse performance causing due to fuse quality is inferior;
10) easy and safe to operate reliable, be easy to safeguard.
Based on above-mentioned technical advantage, all insulation expulsion fuse comes off in antifouling, anti-fault-free, anti-operation is uneasy should have very large improvement by more traditional drop type aspect congruent, possessing that good antifouling, anti-fault-free comes off, anti-operation is unsafe also has that combined floodgate success rate is high, circuit operation ratio advantages of higher simultaneously, market prospects are extensive, are the renewal products of traditional fuse switch.
