Abstract
The utility model discloses an embedded pole for an indoor vacuum breaker, which comprises an insulating casing. An upper conductor and a lower conductor are arranged on the insulating casing; a vacuum arc extinguish chamber is connected with the upper conductor; an insulating pulling lever and a flexible connecting rod are arranged at the lower part of the vacuum arc extinguish chamber; the flexible connecting rod is arranged between the vacuum arc extinguish chamber and the insulating pulling lever; and the other end of the flexible connecting rod is fixedly installed on the lower conductor. The embedded pole has the advantages that the flexible connecting rod is arranged between the insulating pulling lever and the vacuum arc extinguish chamber, the flexible connecting rod is directly pressed on the vacuum arc extinguish chamber through the insulating pulling lever, and other auxiliary parts are not required, so that the quantity of motion among flexible connection can be effectively reduced in a whole operating circuit, and the embedded pole is applied to the field of breaker poles in the electric industry.
Description
Technical field
The utility model relates to a kind of electric utility circuit breaker polar, particularly relates to a kind of indoor vacuum circuit-breaker pole.
Background technology
The inner dust of piling up easily of the major loop insulating part of assembly type vacuum circuit breaker polar, under severe environmental conditions, can produce condensation, these 2 the built-in electrical insulation performances that can have a strong impact on switch, and the major loop dielectric strength of assembly type vacuum circuit-breaker is low, that circuit breaker must be done could satisfy instructions for use very greatly, causes the assembly type circuit breaker can't satisfy product miniaturization requirement like this.
The conductive pieces that vacuum interrupter is relevant with circuit breaker is embedded into simultaneously in the easy cured solid insulating material of this class of epoxy resin and forms pole, make whole circuit breaker polar become as a whole parts, this pole is called pole, its dielectric strength height of the major loop of this pole, be connected by conductive clip with vacuum interrupter but in circuit breaker polar in the past, be flexible coupling, be located at the side of vacuum interrupter, cause its amount of exercise big, and require the power output height of operating mechanism.
The utility model content
For addressing the above problem, the utility model provide a kind of can effectively reduce be flexible coupling between momental indoor vacuum circuit-breaker pole.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of indoor vacuum circuit-breaker pole, comprise insulation crust, insulation crust is provided with upper conductor and lower conductor, connect with upper conductor and to be provided with vacuum interrupter, the bottom of vacuum interrupter is provided with insulated tension pole, also be provided with the bar that is flexible coupling, the bar that is flexible coupling is arranged between vacuum interrupter and the insulated tension pole, and the other end of the bar that is flexible coupling is fixedly installed on the lower conductor.
Be further used as the improvement of technical solutions of the utility model, upper conductor, lower conductor and vacuum interrupter and insulation crust are solidified as a whole.
Be further used as the improvement of technical solutions of the utility model, be provided with the silica gel transition zone between insulation crust and vacuum interrupter.
The beneficial effects of the utility model: this indoor vacuum circuit-breaker is located between insulated tension pole and the vacuum interrupter with the pole bar that will be flexible coupling, directly be pressed on the vacuum interrupter by the insulated tension pole bar that will be flexible coupling, do not need other any auxiliary components, thereby in the whole operation loop, can effectively reduce the amount of exercise between being flexible coupling.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model embodiment internal structure schematic diagram.
Embodiment
With reference to Fig. 1, the utility model is a kind of indoor vacuum circuit-breaker pole, comprise insulation crust 1, insulation crust 1 is provided with upper conductor 4 and lower conductor 5, connect with upper conductor 4 and to be provided with vacuum interrupter 3, the bottom of vacuum interrupter 3 is provided with insulated tension pole 7, also is provided with the bar 6 that is flexible coupling, the bar 6 that is flexible coupling is arranged between vacuum interrupter 3 and the insulated tension pole 7, and the other end of the bar 6 that is flexible coupling is fixedly installed on the lower conductor 5.
This indoor vacuum circuit-breaker is located between insulated tension pole 7 and the vacuum interrupter 3 with the pole bar 6 that will be flexible coupling, directly be pressed on the vacuum interrupter 3 by insulated tension pole 7 bar 6 that will be flexible coupling, do not need other any auxiliary components, thereby in the whole operation loop, can effectively reduce the amount of exercise between being flexible coupling.
As the utility model preferred embodiment, upper conductor 4, lower conductor 5 and vacuum interrupter 3 are solidified as a whole with insulation crust 1.
As the utility model preferred embodiment, 2 of insulation crust 1 and vacuum interrupters are provided with silica gel transition zone 2.
Silica gel transition zone 2 can reduce the surface stress of vacuum interrupter 3, and whole pole built-in electrical insulation will not be subjected to the influence of environment, reach better insulation effect, and the mechanical strength of pole also can better meet the demands.
Certainly, the invention is not limited to above-mentioned execution mode, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
