Abstract
A sealing pole for a 12 kV high-insulativity vacuum circuit breaker comprises a vacuum switch pipe, an upper outlet seat, a lower outlet seat and an insulating sleeve, wherein, the vacuum switch pipe is positioned inside the insulating sleeve, the vacuum switch pipe is sealed with a layer of silica gel sleeve, the upper outlet seat is fixed at the static end of the vacuum switch pipe, the upper outlet seat, the lower outlet seat and the insulating sleeve are combined into a whole with epoxy resin through injection molding, and the outer surfaces of the upper and the lower outlet seats are plated with a layer of sliver. By combining the vacuum switch pipe with the upper and the lower outlet seats through injection molding, the sealing pole can effectively fix the vacuum switch pipe, thereby simplifying the assembly of the vacuum circuit breaker. Moreover, the injection molding of epoxy resin on the outer side of the vacuum switch pipe can prevent outside pollutants from entry, thereby greatly improving the pressure resistance of the product.
Description
Technical field
The utility model relates to vacuum circuit-breaker, specifically is a kind of 12KV high-insulativity vacuum circuit-breaker pole.
Background technology
Existing 12KV vacuum circuit-breaker mainly is that vacuum switch tube, last outlet seat, following outlet seat are encased in the epoxy resins insulation tube successively, conductive clip, insulated tension pole is installed then, and is coupled together by insulated tension pole and operating mechanism.In the actual installation process, need to guarantee the position of vacuum switch tube in insulating cylinder very modestly, and must be very careful fixedly the time, the installation difficulty of existing vacuum circuit-breaker is bigger, installs more complicated; Because vacuum switch tube and peripheral components do not form the structure of an integral body, damage easily when being subjected to clashing into; In addition, owing to have the gap between vacuum switch tube and the insulating cylinder, the outer surface of vacuum switch tube adsorbs dust easily and is subjected to the influence of surrounding environment like this, causes the dielectric strength reduction of vacuum switch tube.
Summary of the invention
The utility model provides a kind of 12KV high-insulativity vacuum circuit-breaker pole, can simplify the assembling of vacuum circuit-breaker, blocks the approach of external contamination, greatly improves the withstand voltage properties of product.
A kind of 12KV high-insulativity vacuum circuit-breaker pole, comprise vacuum switch tube, last outlet seat, following outlet seat and insulating sleeve, vacuum switch tube is positioned at insulating sleeve, at vacuum switch tube outer envelope one deck silica gel sheath, outlet seat on the quiet end of vacuum switch tube is fixing, last outlet seat, following outlet seat and insulating sleeve are injection molded into one by epoxy resin, the silver-plated formation silver coating of outer surface of last outlet seat, following outlet seat.
The utility model 12KV vacuum circuit-breaker has following advantage with pole: by vacuum switch tube and last outlet seat, following outlet seat are injection molded into an integral body, on the one hand can be effectively fixing vacuum switch tube, simplify the assembling of vacuum circuit-breaker, on the other hand, by the epoxy resin injection moulding is carried out in the vacuum switch tube outside, block the approach of external contamination, greatly improved the withstand voltage properties of product; The silica gel sheath of vacuum switch tube outer envelope can effectively be protected vacuum switch tube, prevents in transportation or installation process owing to bump causes damage; Last outlet seat, the following silver-plated good electrical conductivity that guarantees of outlet seat.
Description of drawings
Fig. 1 is the structural representation of the utility model 12KV high-insulativity vacuum circuit-breaker with pole.
Among the figure: 1-vacuum switch tube, 2-silica gel sheath, the last outlet seat of 3-, outlet seat under the 4-, 5-insulating sleeve.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the structural representation of the utility model 12KV high-insulativity vacuum circuit-breaker with pole, described 12KV high-insulativity vacuum circuit-breaker comprises vacuum switch tube 1, last outlet seat 3, following outlet seat 4 and insulating sleeve 5 with pole, vacuum switch tube 1 is positioned at insulating sleeve 5, at vacuum switch tube 1 outer envelope one deck silica gel sheath 2, outlet seat 3 on the quiet end of vacuum switch tube 1 is fixing, concrete, the quiet end of vacuum switch tube 1 and last outlet seat 3 are fixed by screw.Last outlet seat 3, following outlet seat 4 and insulating sleeve 5 are injection molded into one by epoxy resin, and wherein insulating sleeve 5 is to be made by epoxide resin material.Epoxy resin is a kind of good insulating material, can hinder dirty and the raising insulation level, and certain rigidity is arranged, and can to a certain degree resist mechanical shock.
In technique scheme, the silver-plated formation silver coating of outer surface of last outlet seat 3, following outlet seat 4 is to guarantee good electrical conductivity.
The utility model 12KV vacuum circuit-breaker has following advantage with pole: by vacuum switch tube 1 and last outlet seat 3, following outlet seat 4 are injection molded into an integral body, on the one hand can be effectively fixing vacuum switch tube 1, simplify the assembling of vacuum circuit-breaker, on the other hand, by the epoxy resin injection moulding is carried out in vacuum switch tube 1 outside, block the approach of external contamination, greatly improved the withstand voltage properties of product; The silica gel sheath 2 of vacuum switch tube 1 outer envelope can effectively be protected vacuum switch tube 1, prevents in transportation or installation process owing to bump causes damage; Last outlet seat 3, the following outlet seat 4 silver-plated good electrical conductivity that guarantee.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
