A drop fuse mounting bracket

Abstract

The invention discloses a drop type fuse mounting bracket. The drop type fuse mounting bracket comprises a top plate, wherein a rotation rod, a fixed pulley and an inserting rod are arranged at the lower part of the top plate from left to right in sequence; a connecting plate perpendicular to the rotation rod is connected with the lower end of the rotation rod; the connecting plate is clamped with the drop type fuse; one end of a cable rope, passing through the fixed pulley, is connected with the connecting plate (2) while the other end of the cable rope is connected with the side wall of a wrapping post; a limiting jack for limiting the rotation of the wrapping post is formed in the inserting rod; the rotation rod is connected with the top plate through a rotation shaft; the rotation shaft is a spring clamp formed by being a metal rod; the spring clamp comprises a convex-structured limiting rod; and a limiting curved surface matched with the limiting rod is arranged on the side wall of the axial hole of the rotation shaft. Due to the bracket, the drop type fuse can be firmly mounted on a cross arm; and meanwhile, the mounting angle of the drop type fuse can be flexibly adjusted according to actual needs of operation sites so as to ensue the normal operation of the drop type fuse.

Description

technical field [0001] The invention relates to an auxiliary device for installing a drop-out fuse, in particular to a mounting bracket for a drop-out fuse that can adjust the installation angle of the drop-out fuse according to actual application requirements. Background technique [0002] Drop-out fuse is the most commonly used short-circuit protection switch for branch lines of 10kV distribution lines and distribution transformers. It is economical, easy to operate, and adaptable to outdoor environments. It is widely used in 10kV distribution lines and power distribution The primary side of the transformer is used for protection and equipment switching and switching operations. The drop-out fuse is installed on the branch line of the 10kV distribution line, which can reduce the scope of power outages. Because it has an obvious disconnection point, it has the function of an isolating switch, creating a safe operating environment for the lines and equipment in the maintenan...

AI Technical Summary

Problems solved by technology

At present, dropout fuses have different models and manufacturers, the voltage level is not high, the installation process is uneven, and the installation angle is not reasonable. In addition, the operating environment of the installation site is also different, so it is directly installed on the cross arm. , it will cause the drop-out fuse to be unable to effectively drop to cut off the fault after the fuse is blown, which will expand the scope of the accident and cause huge losses. Therefore, it is necessary to develop a mounting bracket to securely and reliably fix the drop-out fuse on the While the cross arm is on, the installation angle can be flexibly adjusted according to the actual needs of the operation site to ensure the normal operation of the drop-out fuse
