Insulated holding pole device for replacing drop-out fuse

Abstract

The invention discloses an insulated holding pole device for replacing a drop-out fuse and belongs to the field of auxiliary equipment of power construction. The insulated holding pole device comprises a holding pole. The holding pole comprises an upper pole body and a lower pole body, which are connected through a connecting piece. The top end of the upper pole body and the bottom end of the lower pole body are respectively provided with a wire clamper. The bottom end of the upper pole body is provided with an upper clamping piece; and the top end of the lower pole body is provided with a lower clamping piece. The connecting piece comprises an upper connector arranged at the bottom end of the upper pole body and a lower connector arranged at the top end of the lower pole body. The upper clamping piece is connected to the upper connector; the lower clamping piece is connected to the lower connector; an upper spring is arranged between the upper clamping piece and the upper connector; and a lower spring is arranged between the lower clamping piece and the lower connector. Through the upper spring, the upper clamping piece is allowed to have a certain pre-tightening force when fixingthe whole body, and through the lower spring, the lower clamping piece is also allowed to have a certain pre-tightening force when fixing the whole body, so that stability of the insulated holding pole device when wholly fixed to a cross-arm can be improved based on combination of the upper clamping piece and the lower clamping piece.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for electric power construction, in particular to an insulating pole holding device for replacing a dropout fuse. Background technique [0002] The drop-out fuse is installed on the branch line of the 10kV distribution line, which can reduce the scope of power failure. Because it has an obvious disconnection point, it has the function of an isolating switch, creating a safe operation for the lines and equipment in the maintenance section. environment, increasing the sense of security of maintenance personnel. The drop-out fuse is installed on the distribution transformer and can be used as the main protection of the distribution transformer. Therefore, the drop-out fuse has been widely used in 10kV distribution lines and distribution transformers. [0003] At present, since there is no special tool for fixing the drain wire when replacing the drop-out fuse on the 10kV line, when repla...

AI Technical Summary

Problems solved by technology

In the process of replacing drop-out fuses, maintenance personnel may touch the connection when the body is at low potential or the insulation and shielding of the connection is not tight, which may cause electric shock injury due to a ground fault.

In addition, due to factors such as the compact layout of the distribution line device and the narrow space, swinging may occur when clips or ropes are used to temporarily fix the live drain wire. Safety cannot be effectively guaranteed
