Problems solved by technology

In the construction of substations, according to the design requirements, some high-voltage isolation switches need to have a higher height from the ground, and the height is generally about 8m to 10m. When using the switch lever to switch the switch at this position, there are the following Problems: 1. The brake lever is long and has a large degree of curvature. It is difficult to control and adjust the direction of the brake lever during the process of closing the brake. 2. The length of the brake lever results in a large weight, which affects the physical fitness of the operator. Certain requirements; 3. In some strong wind conditions, due to the long brake lever, the Baidu range of the brake lever under the action of wind is relatively large, which increases the difficulty of controlling the brake lever

Abstract

The invention provides a switching-off device comprising a switching-off rod, a mobile trolley, a horizontal fine-adjusting mechanism, a longitudinal fine-adjusting mechanism, and a pull rod fixing mechanism. The switching-off rod comprises a switching-off hook and an insulated rod, and the switching-off hook sleeves the top end of the insulated rod through a sleeve. A cross rod is arranged on the inner top end of the sleeve, and a cross groove matching the cross rod is arranged in the top end of the insulated rod. The horizontal fine-adjusting mechanism is arranged on the base plate of the mobile lower trolley, the longitudinal fine-adjusting mechanism is arranged on the horizontal fine-adjusting mechanism, and the pull rod fixing mechanism is arranged on the longitudinal fine-adjusting mechanism. The insulated rod is arranged inside a fixed sleeve of the pull rod fixing mechanism in a sleeving mode. The switching-off device is simple in structure and convenient to operate. The fixed sleeve inside the pull rod fixing mechanism can effectively limit the swing amplitude of the switching-off rod under the condition of strong wind, so an operator can finish switching-off more easily. Therefore, the work intensity is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a switching tool used in the field of power supply, in particular to a switching device which can also be used under strong wind conditions. Background technique [0002] Switching operation is an essential work process in the operation and maintenance of substations. Operators generally use the switch lever to adjust the isolation switch. In the construction of substations, according to the design requirements, some high-voltage isolation switches need to have a higher height from the ground, and the height is generally about 8m to 10m. When using the switch lever to switch the switch at this position, there are the following Problems: 1. The brake lever is long and has a large degree of curvature. It is difficult to control and adjust the direction of the brake lever during the process of closing the brake. 2. The length of the brake lever results in a large weight, which affects the physical fitness of the operator. Certain...
