Abstract
The utility model provides a sealed pole column. One side of a barrel-shaped insulating body is provided with an upper wire outlet and a lower wire outlet, wherein the upper wire outlet and the lower wire outlet are respectively embedded with an upper wire discharging seat and a lower wire discharging seat. The sealed pole column has the key point that the shape of the back of the insulating body is concave arc, and an excircle surface of the upper wire discharging seat and the upper end of the insulating body are provided with a plurality of reinforcing ribs. After the shape of the back of the insulating body is changed to be concave arc, the sealed pole column can extend the distance between the back part of the lower wire discharging seat and a metal plate of a circuit breaker under no change of the installing condition, thereby being capable of effectively avoiding the phenomenon of electric discharge, and improving the reliability of the whole circuit breaker; after the reinforcing ribs are additionally arranged on the excircle surface of the upper wire discharging seat and the upper end of the insulating body, the sealed pole column not only can improve the heat-dissipating capability and the creep resistance, but also is hard to crack; and after barrel arms of the upper wire outlet and the lower wire outlet are changed to be long barrel arms, the sealed pole column leads an electricity-conducting surface to be positioned at the inner parts of the upper wire outlet and the lower wire outlet, thereby effectively extending creep distance.
Description
[technical field]
The utility model relates to a kind of pole, particularly a kind of vacuum circuit-breaker pole.
[background technology]
The structure of existing pole comprises outlet seat up and down, vacuum interrupter, epoxyresin insulator and installation inserts etc., and the outlet seat is embedded in line outlet up and down up and down, and the inside and outside wall of insulator bottom is provided with interior outer skirt.There are the following problems in actual applications for the pole of this structure: 1, under the certain situation in mounting distance and space, because the pole of existing structure is placed restrictions on by the insulator shape, in running, easily produce electric discharge phenomena owing to the hypotelorism between the outlet seat back side and the circuit breaker metallic plate, reduced whole circuit breaker reliability of operation.2, the upper end of insulator exists heat-sinking capability difference and problem easy to crack owing to be subjected to contact, product structure factor affecting in the practical application.
[summary of the invention]
For overcoming the above-mentioned deficiency of prior art, the utility model aims to provide a kind of pole, this pole is under the constant situation of mounting condition, not only can effectively eliminate the electric discharge phenomena between the outlet seat back side and the circuit breaker metallic plate, thereby help improving the complete machine insulation level of fixed sealing type circuit breaker, and can also improve product the be in operation heat radiation and the ability of cracking resistance.
Realize that the above-mentioned purpose technical scheme is as follows, this pole comprises the insulator of tubular, one side of insulator is provided with line outlet, following line outlet, be respectively equipped with outlet seat and following outlet seat in last line outlet and the following line outlet, it is characterized in that: be concave arc shape with the described shape that goes up line outlet, line outlet is relative down insulator back, have many shaft orientation reinforcing ribs on the described periphery of going up the outlet seat.
During concrete enforcement, be the heat-sinking capability of raising product in running, and the creep-resistant property of insulator, many reinforcements be provided with in the periphery of described insulator upper end.
During concrete enforcement, the reinforcement of described insulator periphery has three types, is respectively throat's reinforcement, rear portion reinforcement and top reinforcement.
During concrete enforcement, the shaft orientation reinforcing rib that have more than 6 on the periphery of described upward outlet seat, the cross section is semicircle shape.
Beneficial effect: compare with known technology, the utility model mainly contains the innovation of following several respects: the one, with described and last line outlet, after down the relative insulator back shape of line outlet makes concave arc shape into, under the constant situation of mounting condition, can increase the distance between the outlet seat back side and the circuit breaker metallic plate, thereby can effectively avoid electric discharge phenomena, the reliability of whole circuit breaker is improved.The 2nd, after setting up shaft orientation reinforcing rib on the last outlet seat, both helped when producing, improving the binding ability of outlet seat and epoxy, help when operation, improving the heat-sinking capability of outlet seat again.The 3rd, after top reinforcement, rear portion reinforcement and throat's reinforcement are set up in the upper end of insulator, help improving the integral heat sink ability of product in running, both solve existing product weak heat-dissipating, the easy problem that ftractures, improved the creep-resistant property of insulator again.In addition, after the tube arm that will hold outlet seat and following outlet seat makes a lengthening arm into, increased creepage distance effectively, made product reliability higher.

[embodiment]
Referring to Fig. 1, and in conjunction with Fig. 2-Fig. 5.Insulator 1 global shape that epoxide resin material is made, inner connecting structure are basic consistent with prior art, difference is that the described shape that goes up line outlet 11, line outlet 12 is relative down insulator back 18 (referring to Fig. 5) is concave arc shape, and its circular arc size can depend on the circumstances.In addition, throat's reinforcement 13 is set respectively in the upper end of insulator 1, rear portion reinforcement 14 and top reinforcement 15, the quantity of reinforcement can be decided as required.The described tube arm of going up line outlet 11 and following line outlet 12 is a lengthening tube arm 111, makes the conducting surface 21 of outlet seat 2 and following outlet seat 3 be positioned at the inside of an arm 111 that extends, and can increase creepage distance like this.
Referring to Fig. 6.During concrete enforcement, the shaft orientation reinforcing rib 24 that have more than 6 on the periphery 23 of last outlet seat 2, the cross section is semicircle shape, effect is better.
