Breaker test line hitching rod

Abstract

The invention relates to a breaker test line hitching rod. The breaker test line hitching rod comprises a clamping head and an operation rod, and the clamping head is inserted into an insertion hole in an upper part of the operation rod; the clamping head comprises a fixed clamping head, a moving clamping head and a movable guide rod; and the overall fixed clamping head is 7-shaped, the bottom of the fixed clamping head is connected with the movable guide rod, the moving clamping head is installed at the middle part of the fixed clamping head and is disposed in a manner that the moving clamping head is parallel to the top of the fixed clamping head, a fixed pulley is installed on the fixed clamping head, one end of a transmission steel wire rope is connected to the moving clamping head, and the other end of the transmission steel wire rope bypasses the fixed pulley and then is connected to the movable guide rod. A breaker wire plate is clamped through cooperation between the fixed clamping head and the moving clamping head performing upward movement, and the clamping head keeps in a clamped state by utilizing a friction force between the steel wire rope and the moving clamping head. The breaker test line hitching rod ahs the advantages of the light weight, firm structure and convenient assembling and disassembling; no vibration can enable the clamping head to fall off after the clamping head is clamped tightly; and the problem of test line hitching unsafety when a breaker characteristic test is performed is solved completely.

Description

technical field [0001] The invention relates to a special hook-up tool for a circuit breaker test line of electric equipment, in particular to a hook-up rod for a circuit breaker test line. Background technique [0002] Currently, two methods are generally used to test the characteristics of the circuit breaker. One is to use the method of manually ascending and hooking the test line. If you use a ladder to climb high, the safety risk is high, especially when performing a characteristic test on a 220kV circuit breaker, you need to climb more than 6 meters, which is prone to fall accidents from high places, and at least 3 operators are required. If a lift truck is used, at least 3 operators are required, and the lift truck needs to be moved at least three times, which increases the work intensity. If you use a boom truck, you also need to consider the working environment of the bucket truck. Some parts cannot be reached by the bucket truck, which also increases the operating...
