A portable low-voltage knife switch bracket with adjustable angle

Abstract

The invention provides a portable low-voltage isolator bracket with an adjustable angle, which comprises a semicircular main body plate, a low-voltage isolator insertion part arranged on the straightedge of the main body plate and an insulation rod connection part arranged at the arc end of the main body plate, wherein the insulation rod connection part comprises a main body part, a connection slot at the bottom part, locking bolts arranged corresponding to the connection slot and a top fork frame; the upper part of the top fork frame is hinged on the main body plate and can rotate along a hinging part; the arc end of the main body plate is located in a gap in the middle of the top fork frame; the main body plate is provided with an arc long hole; the middle part of the top fork frame isprovided with a positioning bolt; the positioning bolt is clamped in the arc long hole; the bolt head of the positioning bolt and the nut are clamped at two sides of the top fork frame for clamping the top fork frame; and the shape of the arc long hole is arranged corresponding to the trajectory of the positioning bolt. The portable low-voltage isolator bracket with an adjustable angle has the advantages of scientific design, adjustable operation angle, detachable connection with the insulation rod, flexible operation and low cost.

Description

technical field [0001] The invention relates to an adjustment device for a low-voltage knife switch, in particular to a portable angle-adjustable low-voltage knife switch bracket. Background technique [0002] The distribution transformer low-voltage switch is composed of a base, a post insulator, and a conductive mechanism. As an outdoor line component, the low-voltage knife switch is prone to corrosion due to the erosion of natural factors, the conductive part and the mechanical transmission part of the isolation knife switch, or the hook part of the low-voltage isolation knife switch is damaged or damaged due to working overvoltage and operating overvoltage. It is an important reason for the failure of operation and the failure of closing and closing. According to the relevant information, it is found that 100% of the operations with a closing time of more than ten minutes have damage, damage, and deformation of the hook, which makes the existing tools unable to close.

Problems solved by technology

As an outdoor line component, the low-voltage knife switch is prone to corrosion due to the erosion of natural factors, the conductive part and the mechanical transmission part of the isolation knife switch, or the hook part of the low-voltage isolation knife switch is damaged or damaged due to working overvoltage and operating overvoltage. It is an important reason for the failure of operation and the failure of closing and closing. According to the relevant information, it is found that 100% of the operations with a closing time of more than ten minutes have damage, damage, and deformation of the hook, which makes the existing tools unable to close. Based on For all the above reasons, in the daily distribution network emergency repair process, it is often necessary to cut and close operations and emergency repairs.
