Short circuit grounding wire device with locking function

Abstract

The invention relates to a short circuit grounding wire device with a locking function. The short circuit grounding wire device comprises an operation rod (1), a grounding chuck (4), a grounding wire guide-out end (25), a grounding lead (26) and a grounding end chuck (5). The grounding chuck (4) is connected with the grounding lead (26) through the grounding wire guide-out end (25). The grounding lead (26) is connected with the grounding end chuck (5). The side, close to the grounding chuck (4), of the operation rod (1) is provided with an electrified pre-warning device (6). The pre-warning device (6) comprises a locking device (7) for preventing misoperation. Locking can be performed through the locking device (7) when grounding misoperation occurs, and personal safety of operators is guaranteed. Compared with the prior art, the short circuit grounding wire device is safe and reliable, convenient to operate, and the like.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a short-circuit grounding wire device with a blocking function. Background technique [0002] The short-circuit grounding wire is an indispensable safety tool for power equipment maintenance. However, once there is a mistake in the operation of adding a short-circuit grounding wire, such as adding a short-circuit grounding wire to a live power equipment by mistake, it will cause serious damage to the high-voltage equipment. Metallic grounding short circuit produces extremely large short circuit current and high temperature arc, leading to serious accidents such as instant burning of on-site equipment, arc burns and even death of operators. [0003] With the deepening of the anti-misoperation management system and the advancement of technology, misoperation accidents in the power industry have been decreasing year by year. However, many vicious misoperation accidents have not been fun...

[0002] The short-circuit grounding wire is an indispensable safety tool for power equipment maintenance. However, once there is a mistake in the operation of adding a short-circuit grounding wire, such as adding a short-circuit grounding wire to a live power equipment by mistake, it will cause serious damage to the high-voltage equipment. Metallic grounding short circuit, resulting in huge short circuit current and high temperature arc, leading to serious accidents such as instant burning of on-site equipment, arc burns and even death of operators

[0003] With the deepening of the anti-misoperation management system and the advancement of technology, misoperation accidents in the power industry have been decreasing year by year. However, many vicious misoperation accidents have not been fundamentally eliminated. happened

The short-circuited grounding wire on the live wire not only causes serious equipment damage, but also causes extremely serious personal injury. However, there is still no technical solution to this problem

Chinese patent CN201210398449 proposes an anti-misoperation electric power grounding wire. This technology can prevent "hanging the equipment end first and then the grounding end" by setting an interlocking device between the grounding chuck and the grounding end chuck of the conventional short-circuit grounding wire. In case of illegal operation, but for the situation that the grounded equipment is called suddenly, the equipment nameplate is wrong, the electroscope is faulty, etc., the technology is completely ineffective. It is particularly necessary to hang a short-circuit grounding wire
