Embodiment 1

[0022] The explosive package adopts emulsion explosive with a detonation velocity of 4000m / s, the charge is 500g, and the package is a paper tube. The No. 8 electric detonator is inserted in the package, and the package is placed under the 50kV transmission line covered with mixed rime. The bag is 10m away from the power line, and is directly connected to a place 100m away from the drug bag with a wire, and the battery is used to energize the detonator to detonate the mixed rime on the power line. The deicing effect is 50%, and there is no damage to the power line.

Embodiment 2

[0024] The explosive cartridge adopts emulsion explosive with a detonation velocity of 6000m / s, the charge is 500g, the cartridge is a plastic tube, and the lower part of the plastic tube is equipped with a remote detonation device and a safety mechanism, which is collectively called a fixed detonation tube. The detonation tube is placed under the 50kV transmission line covered with mixed rime ice, and the tube is 20m away from the transmission line. After installation, the remote control is used to detonate 200m away. The deicing effect is 40%, and there is no damage to the transmission line.

Embodiment 3

[0026] The explosive package adopts the gunpowder-improved explosive formula with a detonation velocity of 3000m / s, and the charge is 400g. The package adopts a plastic tube charging method, and the detonation adopts a delayed charge ignition and detonation method. A launch propulsion mechanism is installed under the plastic tube, which is called It is a launch-type detonation charge tube, which is launched with a simple fiberglass launch tube. When fired within 3m of the 50kV transmission line covered with mixed rime, the charge detonates, the deicing effect is 60%, and there is no damage to the transmission line.

The technology ignites an explosive blasting cartridge or a gunpowder blasting cartridge with certain explosive load near the transmission linesand the towers for detonation or deflagration, and the shock waves with certain strength are formed after the detonation of the explosive blasting cartridge or the deflagration of the gunpowder blastiand the towers for detonation or deflagration, and the shock waves with certain strength are formed after the detonation of the explosive blasting cartridge or the deflagration of the gunpowder blasting cartridge; due to difference of responses of the brittle ice and the flexible transmission lines to the shock waves, the ice covering on the transmission lines is broken and falls off under the actng cartridge; due to difference of responses of the brittle ice and the flexible transmission lines to the shock waves, the ice covering on the transmission lines is broken and falls off under the action of the shock waves; therefore, the technology achieves the aim of ice removal. The technology can be applied to remove the ice covering on the transmission lines and the towers with different voltion of the shock waves; therefore, the technology achieves the aim of ice removal. The technology can be applied to remove the ice covering on the transmission lines and the towers with different voltag

Description

technical field [0001] The invention relates to a shock wave deicing technology for transmission lines, in particular to deicing transmission lines and towers with different voltage levels, different heights and various complex terrains, and belongs to the technical field of explosive charges. Background technique [0002] The development of the world's economy and technology has had a major impact on the earth's environment, oceans and atmosphere, resulting in a gradual warming of the global climate. Ice and snow disasters have become one of the serious hidden dangers affecting the safe operation of high-voltage transmission lines. Ice and snow disasters have two hazards to high-voltage transmission lines. One is that the icing of transmission lines exceeds the design standard, which can cause disconnection and tower collapse accidents due to overwhelm; Therefore, when the transmission line is seriously ice-covered, there will be disconnection, pole (tower), etc., resultin...
