Abstract
The utility model relates to a high-voltage vacuum circuit breaker, and specifically relates to a solid-sealed polar pole of an indoor high-voltage vacuum circuit breaker. The solid-sealed polar pole of the indoor high-voltage vacuum circuit breaker comprises a vacuum explosion chamber, an upper wiring terminal and a lower wiring terminal arranged on an upper side and a lower side of the vacuum explosion chamber, a heat dissipation cover arranged on an upper side of the upper wiring terminal, a resin layer is arranged on an inner side face of the vacuum explosion chamber, and a sealing cover is arranged between the resin layer and the lower wiring terminal. According to the utility model, resin layers are arranged at the joints of the vacuum explosion chamber and the upper wiring terminal, the lower wiring terminal and the heat dissipation cover so as to prevented the conductor of the breaker polar pole from being influenced by external environment, thereby improving the anti-pollution capability of the surface of the polar pole, and improving the electrical insulation performance and adaptive performance of the breaker polar pole.
Description
Technical field
The utility model relates to indoor high-voltage vacuum circuit breaker, specifically the pole of high-pressure vacuum breaker.
Background technology
At present, solid sealing type vacuum circuit breaker generally adopts the insulated barrel-type mounting structure, it is installed in vacuum interrupter in the insulating cylinder, although can avoid some slight bumps, but owing to still adopting air insulation, the junction of heat dissipating housing and upper terminals etc. exposes in air, is subject to the impact of airborne filth, dust etc., thereby so that the charged body insulation against ground of circuit breaker is subjected to external interference, reduced the ability that pole conforms.
The utility model content
For above-mentioned technical problem, the utility model provides the pole of the stronger indoor high-voltage vacuum circuit breaker of better, the applicable ability of a kind of insulation property.
The technical scheme in the invention for solving the above technical problem is: the pole of indoor high-voltage vacuum circuit breaker, comprise vacuum interrupter, be positioned at upper terminals and the lower terminals of this vacuum interrupter upper and lower sides, described upper terminals upside is provided with heat dissipating housing, described vacuum interrupter medial surface is provided with resin bed, is provided with seal closure between this resin bed and lower terminals.
Further, be provided with described resin bed between described upper terminals and the heat dissipating housing.
As can be known from the above technical solutions, the utility model is by arranging resin bed in the junction of vacuum interrupter and terminals up and down and heat dissipating housing etc., avoided the circuit breaker polar electric conductor to be subject to the impact of external environment, not only improve pole surface anti-pollution ability, and improved electric insulation property and the conformability of circuit breaker polar.
Description of drawings
Fig. 1 is the structure cutaway view of a kind of optimal way of the utility model.
Embodiment
Below in conjunction with Fig. 1 the utility model is described in further detail:
The pole of this circuit breaker comprises vacuum interrupter 1, is positioned at upper terminals 2 and the lower terminals 3 of this vacuum interrupter upper and lower sides, and described upper terminals 2 upsides are provided with heat dissipating housing 4, improves heat dispersion; Described vacuum interrupter 1 medial surface is provided with resin bed 11, in order to improve sealing property, is provided with seal closure 5 between this resin bed and lower terminals; Be provided with described resin bed 11 between described upper terminals and the heat dissipating housing.The utility model has avoided the circuit breaker polar electric conductor to be subject to the impact of external environment by resin bed is set, and has not only improved pole surface anti-pollution ability, and has improved electric insulation property and the conformability of circuit breaker polar.
Above-mentioned execution mode is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that do not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present utility model.
