AI Technical Summary

Technical Problem

The installation and disassembly of traditional disconnect load switches are cumbersome, require a lot of tools, affect the construction progress, and frequent installation and disassembly can easily lead to thread wear, reduced connection reliability, increased manpower and material costs, and increased maintenance difficulty and safety risks in complex environments.

Method used

The design employs an I-shaped connector with a slot and an L-shaped clamping plate with a spring connection to achieve quick and stable connection and disassembly between the isolating load switch body and the mounting base. The spring force causes the L-shaped clamping plate to snap into the slot of the I-shaped connector, and the inclined surface design improves the convenience and stability of installation and disassembly.

Benefits of technology

It enables rapid and stable connection and disassembly of isolating load switches, improving installation efficiency and usage flexibility, reducing maintenance costs and safety risks, and enhancing connection reliability.

Abstract

This utility model discloses an isolating load switch for switchgear, including an isolating load switch body and a mounting base. An I-shaped connecting seat with a slot is fixedly mounted on the bottom surface of the isolating load switch body. A fixing groove is provided on the mounting base, and a spring connecting block is fixedly mounted on the bottom surface of the fixing groove. At least two springs are fixedly mounted on both sides of the spring connecting block. Two L-shaped clamping plates are arranged opposite each other in the fixing groove. The upper parts of the two L-shaped clamping plates are engaged with the slots on the I-shaped connecting seat. The springs on the left and right sides are respectively fixedly mounted on the lower parts of the corresponding L-shaped clamping plates. At least two first mounting plates are fixed on both sides of the mounting base. This utility model enables quick and stable connection and disassembly of the isolating load switch body and the mounting base, facilitating the installation, maintenance, and replacement of the isolating load switch, and improving installation efficiency and operational flexibility.
