Abstract

The invention is applied to the technical field of electrical equipment, and provides a spacer wrench which comprises a shell body. A ratchet wheel and a rack meshed with the ratchet wheel are arranged in the shell body, a handle is further arranged on a rotating shaft of the ratchet wheel and further provided with a driving pawl used for driving the ratchet wheel to rotate in the forward direction, the shell body is further provided with a check pawl used for preventing the ratchet wheel from rotating in the reverse direction, and both the driving pawl and the check pawl lean against the ratchet wheel. When the angle between the handle and the rack is less than a certain angle, both the driving pawl and the check pawl disengage from the ratchet wheel, a blocking-out device is further arranged at one end of the rack, and a fixing splint is further arranged on one side, close to the blocking-out device, of the shell body. According to the spacer wrench, transmission of the ratchet wheel is combined with transmission of the rack, and the interval between the blocking-out device and the fixing splint can be rapidly adjusted through rotating of the handle. Compared with an existing spacer wrench, working efficiency of installation and replacement for a spacer is improved, and the risk of charged work is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a spacer bar wrench. Background technique [0002] The main purpose of the spacer is to limit the relative movement between the sub-conductors of the power transmission line and to maintain the geometry of the split conductors under normal operating conditions. The emergency repair center is currently undertaking operation and maintenance of the line voltage levels of AC 500kV ultra-high voltage transmission lines and DC ±800kV ultra-high voltage transmission lines. During routine technical overhaul and live overhaul, the damaged spacer rods that have been subjected to electromechanical loads for a long time are usually replaced. The spacer wrench for splitting wires is a special tool for installing and removing various types of spacer rods. It plays an important role in the maintenance of power transmission lines play an important role. [0003] Such as ...
