Abstract

The invention relates to an operating lever and operating method special for rapid installation of a ground wire. The operating lever comprises an external insulation tube (12), a fixing nut (10) is connected with a telescopic support (5), an internal insulation tube (11) is fixedly connected with a hollow wire tube (9) which is connected with a circular tube (7) through a rotary connector (8), the circular tube (7) is fixedly connected with an opening and closing clip (1), and the opening and closing clip (1) is fixedly connected with a groove type grounding clamp clip (2). According to the lever principle of machinery, labor is saved in the operation process, the application is convenient, time for installing the ground wire is shortened, high-place operation procedures are simplified, time for high-place operation is shortened, so that the operation risk and the labor intensity of operation workers are reduced, and meanwhile operation efficiency in power outrage is improved. The operating lever is convenient to carry, easy to operate, capable of saving labor in the operation process, low in cost, and easy to popularize and apply in the field of transmission production.

Description

technical field [0001] The invention relates to a special operating rod for quick installation of ground wires and an operating method. Background technique [0002] The special operating rod for quickly installing the grounding wire is a special tool for installing and wiring the power transmission line when the power is cut off. In the case of power outage operation and maintenance of 220kV and above voltage transmission lines, it is necessary to install grounding wires on the three-phase conductors at both ends of the work area to ensure the personal safety of operators. Under the current conditions, operators use the throwing method to install the grounding wire. Due to the influence of the tower type, wire position and climate (especially in windy weather), the installation of the grounding wire is time-consuming and laborious, which is not conducive to the personal safety of the operators and affects the power outage operation. Bad results for efficiency. Contents o...
