Adjustable conductive arm of isolating switch and double-arm isolating switch

Abstract

The invention relates to the field of double-arm vertical telescopic disconnecting switches, in particular to an adjustable conductive arm of a disconnecting switch, which comprises a conductive seat, a conductive hoop and a flexible connector, and is characterized in that the conductive seat is fixedly connected with a conductive box, the conductive hoop is rotatably connected with the conductive box, the conductive seat and the conductive hoop are coaxially arranged, and the flexible connector is connected with the conductive seat. The conductive seat is arranged in the conductive hoop; the flexible connector is arranged around the outer wall of the conductive seat, one end of the flexible connector is connected with the conductive seat, and the other end of the flexible connector is connected with the conductive hoop; during closing, the flexible connection is in a contraction state; and the conductive hoop is connected with the conductive knife switch. According to the invention, the flexible connection is installed outside the conductive box, and only the transmission crank arm, the pull rod and other structures are reserved in the conductive box, so that the structure of the conductive box is not affected after the capacity of a product is increased or the structure of the flexible connection is changed, and the influence of the change of the structure of the flexible connection on the size of the double-arm vertical telescopic disconnecting switch conductive box is avoided.

Description

Technical field [0001] The present invention relates to the field of a two-arm vertical telescopic isolation switch, specifically an adjustable conductive arm of an isolation switch and a two-arm isolation switch. Background [0002] Due to its sealed conductive box structure, the double-arm vertical telescopic disconnect switch can protect the transmission components and soft connections, and is widely used in environments such as high winds and snow in northern China. [0003] In order to meet the needs of users on the market to increase the current capacity, when the product is improved, it is not only necessary to increase the through-current section of the conductive pipe, but also to increase the number, thickness and width of the soft connection, so that the volume of the conductive box will increase accordingly. [0004] The soft connection of the existing double-arm vertical telescopic disconnect switch is placed in the conductive box and outside the box, which will affe...

AI Technical Summary

Problems solved by technology

[0004] The soft connection of the existing double-arm vertical telescopic isolating switch is placed in the conductive box or outside the box. If placed in the box, the volume of the conductive box will be affected by the change of the current capacity, and it is not conducive to the transmission system. layout

[0005] The structure currently placed outside the box lacks protective measures, and after long-term operation, the soft connection will be damaged by strong winds

[0006] The adjustment of the opening and closing positions of the existing double-arm vertical telescopic isolating switch depends on the small adjustment of the transmission rod in the conductive box and the adjustment of the position of the transmission arm with the drill, the accuracy is poor, and stepless adjustment cannot be realized
