Grounding device

Abstract

The invention provides a grounding device. The grounding device comprises an insulation puncture grounding wire clamp, a grounding ring, a puncture pressure control mechanism, a puncture pressure adjusting mechanism, a driving mechanism and an electric control system. The insulation puncture grounding wire clamp comprises an upper housing, a lower housing, telescopic pull rods and nuts. The puncture pressure control mechanism comprises floating gears, sleeves and a puncture stroke switches, and contact ends of the floating gears and the sleeves form ratchet structures. The puncture pressure adjusting mechanism is a moment setting spring. The electric control system comprises a power supply module, a microcontroller, a high-voltage electricity verification module and a remote control transmit-receive module. The driving mechanism comprises a driving motor and a transmission gear. The driving motor, the puncture stroke switches, a high-voltage electricity verification circuit and a remote control transmit-receive circuit are respectively electrically connected with the microcontroller. According to the invention, safety hidden troubles in the grounding processing of a power transmission line can be fundamentally eliminated, the labor intensity of working personnel is reduced, and the working efficiency is improved.

Description

【Technical field】 [0001] The invention relates to a grounding jig for piercing an insulated wire, in particular to a grounding device for grounding a high-voltage insulated wire. 【Background technique】 [0002] In recent years, the use of overhead insulated conductors has become more and more popular. According to the requirements of the safety regulations of the electric power industry, in order to ensure the safety of the operation, before the maintenance or repair of the transmission line, it is necessary to use the grounding clamp on the premise of confirming that the transmission line is powered off. The transmission lines to be repaired shall be grounded. Since overhead insulated wires are covered with insulating sheaths, they cannot be grounded as conveniently as ordinary steel-cored aluminum stranded wires. [0003] At present, the insulation piercing grounding clip commonly used for the grounding treatment of high-voltage insulated wires at home and abroad has the ...

Since overhead insulated wires are covered with insulating sheath, they cannot be grounded as conveniently as ordinary steel-cored aluminum stranded wires

[0003] At present, the insulation piercing grounding clamp commonly used for the grounding treatment of high-voltage insulated wires at home and abroad has the advantages of live work, no need to peel, good self-sealing and small electrical contact resistance, but its disadvantages are also obvious. , mainly: the puncture operation needs to be performed manually, the puncture pressure is not easy to control, and the operation is difficult when working at heights, and, when performing the puncture operation, the operator's body needs to be in direct contact with the insulating puncture grounding clamp

If there is a quality defect in the insulation piercing grounding clamp, and the power transmission line is not cut off, it may also endanger the personal safety of the operator
