Abstract
The utility model provides a solid-sealed polar pole used for vacuum circuit breaker including an epoxy resin insulator, an upper wire outlet base, a vacuum arc extinguish chamber, a lower wire outlet base and an installation insert. A piece of insulation clapboard is arranged on an outer wall of the epoxy resin insulator on the back of the upper wire outlet base and the lower wire outlet base. The insulation clapboard equals to an additional epoxy resin insulator added between the solid-sealed polar pole and a face plate of the circuit breaker. The insulation clapboard separates the solid-sealed polar pole and the circuit breaker, thereby solving a problem that the upper and lower wire outlet base of the solid-sealed polar pole discharge to a metal plate of the circuit breaker and improving the integral strength of the solid-sealed polar pole as well. Moreover, by adding an inner insulation sleeve, the electric discharge phenomenon that an inner insulation pull rod discharges to the metal installation plate of the circuit breaker is eliminated and the creep distance in the solid-sealed polar pole in increased. What is more, by designing cross sections of the upper and the lower wire outlet base in a transversely concave structure, an interpolar creep distance between the upper and the lower wire outlet base and a creep distance between the lower wire outlet base and the ground are increased. The solid-sealed polar pole used for the vacuum circuit breaker in the utility model has advantages of high safety performance and is suitable for using in high altitude regions.
Description
[technical field]
The utility model belongs to a kind of electic protection control device, relates in particular to a kind of vacuum circuit-breaker and uses pole.
[background technology]
Existing vacuum circuit-breaker is with the structure of pole; Mainly by epoxyresin insulator; And be arranged on last outlet seat, vacuum interrupter, the following outlet seat on this epoxyresin insulator and the inserts formation is installed; Its problem that in practical application, exists is: between upper and lower outlet seat and the circuit breaker metallic plate, and have electric discharge phenomena between interior insulated tension pole and the circuit breaker metallic plate; Moreover, because the end face interpolar creepage distance of upper and lower outlet seat is short, so that there is poor safety performance in product, is difficult to the problem that use the high altitude localities more than 4000m.
[summary of the invention]
For solving the problems referred to above that prior art exists; The utility model aims to provide a kind of vacuum circuit-breaker and uses pole; This pole has solved the electric discharge phenomena that exist between upper and lower outlet seat and the circuit breaker metallic plate well; It is good to have security performance, is adapted at the above high altitude localities of 4000m advantages of application.
Realize that the above-mentioned purpose technical scheme is following; This vacuum circuit-breaker is with the structure of pole; Comprise epoxyresin insulator, last outlet seat, vacuum interrupter, following outlet seat and inserts is installed; Said installation inserts is positioned on the baseplane of said epoxyresin insulator, it is characterized in that: be positioned at said on the outer wall of epoxyresin insulator at outlet seat and the following outlet seat back side, be provided with an insulating barrier.
During practical implementation; Described insulating barrier and said epoxyresin insulator are single piece; The cavity that has a upper and lower opening between the outer wall of this epoxyresin insulator and the inwall of this insulating barrier, the lowest part of this cavity are positioned at the horizontal extended line below of said outlet seat extreme lower position down.
During practical implementation, on the baseplane of said epoxyresin insulator, have an interior insulating case, form behind the bottom outlet evagination that this interior insulating case is said epoxyresin insulator.
During practical implementation, said cross section of going up outlet seat, following outlet seat end face is horizontal concave structure.
Beneficial effect: compared with prior art; The utility model is on the outer wall of the epoxyresin insulator at the last outlet seat and the following outlet seat back side; After insulating barrier is set, be equivalent between pole and circuit breaker panel, add one deck epoxy insulating board, both are isolated each other; Thereby having solved for a long time, the upper and lower outlet seat of pole has also increased the product bulk strength simultaneously to the electric discharge phenomena of circuit breaker metallic plate.In addition; Set up interior insulating case, with will go up the outlet seat, after down the Cross section Design of outlet seat end face becomes horizontal concave structure, the former; Be equivalent in pole, add one deck epoxy insulating board between the insulated tension pole and the perforate of circuit breaker metal mounting panel; Both are isolated each other, solved for a long time in the pole insulated tension pole to the electric discharge phenomena between the perforate of circuit breaker metal mounting panel, and strengthened the inner creepage distance of product; The latter, the interpolar creepage distance that has strengthened between the upper and lower outlet seat reaches outlet seat creepage distance over the ground down.
[description of drawings]
Fig. 1 is the vertical profile structural representation of an embodiment of the utility model.
Fig. 2 looks up the sectional structure sketch map for Fig. 1's.
Among the figure: go up outlet seat 1, vacuum interrupter 2, following outlet seat 3, epoxyresin insulator 4 is installed inserts 5, insulating barrier 6, cavity 61, interior insulating case 7, concave structure 8.
[embodiment]
Referring to Fig. 1, Fig. 2.Present embodiment comprises outlet seat 1, vacuum interrupter 2, following outlet seat 3; Epoxyresin insulator 4; Inserts 5 is installed, and insulating barrier 6, vacuum interrupter 2 are inlaid in the epoxyresin insulator 4; Following outlet seat 3 is connected with the moved end of vacuum interrupter 2, and last outlet seat 1 is connected with the quiet end of vacuum interrupter 2.Be positioned at said on the outer wall of epoxyresin insulator 4 at outlet seat 1 and following outlet seat 3 back sides, insulating barrier 6 is set.Insulating barrier 6 is a single piece with epoxyresin insulator 4; The cavity 61 that has a upper and lower opening between the inwall of the outer wall of epoxyresin insulator 4 and insulating barrier 6; The lowest part of this cavity 61 is positioned at the horizontal extended line below of outlet seat 3 extreme lower positions down; That is to say that cavity 61 has axially covered the pole zone between last outlet seat 1 and the following outlet seat 3, thus the electric discharge phenomena that solved last outlet seat 1 well, existed between outlet seat 3 and the circuit breaker metallic plate down.
During practical implementation, on the baseplane of said epoxyresin insulator 4, have an interior insulating case 7, form behind the bottom outlet evagination that this interior insulating case 7 is said epoxyresin insulator 4.In addition, the cross section of last outlet seat 1 and following outlet seat 3 end faces is horizontal concave structure 8, thereby has strengthened last outlet seat 1, interpolar creepage distance between the outlet seat 3 and following outlet seat 3 creepage distance over the ground down.
The foregoing description only is to explain the invention thinking of the utility model, everyly makes simple change and the structure of coming all should receive the protection of this patent according to the utility model design concept.
