High-voltage cable puncturing device and puncturing method

Abstract

The invention discloses a high-voltage cable puncturing device and puncturing method. The high-voltage cable puncturing device comprises a cable fixing device fixed on a high-voltage cable, a steel nail for puncturing the high-voltage cable, and a puncturing drive device for driving the steel nail to puncture, the puncturing drive device comprises a shell fixed on a fixing support plate, a motor arranged on the shell, a control circuit board and a hydraulic oil cylinder, the piston rod of the hydraulic oil cylinder is fixed with the steel nail, the motor is electrically connected with the control circuit board and controlled to work by the control circuit board, the motor drives the hydraulic oil cylinder to work, and the hydraulic oil cylinder drives the steel nail to puncture the high-voltage cable. The high-voltage cable puncturing device and puncturing method use a wireless remote control mode to control the electric hydraulic puncturing device to work, the operation is safe and reliable, the use efficiency is high, and the operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of cable detection, in particular to a safety tool for piercing whether a high-voltage cable is live. Background technique [0002] For many years, the cable operation and maintenance department must conduct a piercing test on the high-voltage cables to ensure that the cables to be overhauled are not charged, in accordance with the requirements of Article 234 of the industry standard DL409-91 "Electrical Industry Safety Work Regulations (Power Lines)" , using manual piercing, the way of manual piercing is to use a hammer to hammer steel nails so that the steel nails penetrate the cable until the conductor is used, although the identification with a cable recognition instrument before piercing also has a high recognition rate Once the cable identification is wrong, the error Piercing live cables will cause great harm or even life-threatening to operators; although there are stabbing device devices launched by...
