Problems solved by technology

[0002] In January 2008, most parts of Central China, East China, and South China experienced low-temperature, rainy, snowy and freezing weather that was rare in history, causing large areas of power transmission and transformation facilities to be covered with ice. A large number of transmission lines were disconnected, power facilities were extensively damaged, and the grid structure was severely damaged
The passive method has the advantage of low cost, but it cannot prevent the formation of icing, and it is only applicable to specific areas

Abstract

The invention relates to a deicing method for a high-voltage power transmission line and a device. The device is located on a supporting plate of a travel carriage on the high-voltage power transmission line and fixedly provided with an electrolytic cell filled with strong electrolyte solution and the like. The storage battery is charged continuously through electromagnetic inducing electrical energy which is from a solar cell panel and is generated under wind power or movement of three electromagnetic induction coils that are suspended on a beam and from a solar cell plate. The storage battery is connected with the electrolytic cell. Hydrogen and oxygen generated by the electrolytic cell enter a combuster through a delivery pipe, a one-way valve, a polycarbonate pipe and a lock net adaptor, respectively; a spring sheet metal and a thin plate that form an ice and snow detector as well as an electrode connected with a power line of a high-voltage boosting circuit below the reed pipe are arranged at the top of the combuster below the high-voltage transmission line. When the thin plate is covered by ice, and elastic metal and thin plate bend downwards, the free end and the magnetic block at the top of the combuster attract each other, and the power line of a high-voltage boosting circuit is switched on. Mixture of hydrogen and oxygen in the combuster combusts so that the piston body in the combuster strikes the high-voltage transmission line to enable the ice and snow to fall off.

Description

technical field [0001] The invention relates to a high-voltage transmission line deicing device and a deicing method thereof. Background technique [0002] In January 2008, most parts of Central China, East China, and South China experienced historically rare low-temperature, rainy, snowy and freezing weather, causing large areas of power transmission and transformation facilities to be covered with ice. A large number of transmission lines were disconnected, power facilities were extensively damaged, and the grid structure was severely damaged. [0003] From 1980 to 2007, the total investment in power supply in China reached 2,109.7 billion yuan, and the installed capacity and power generation have leapt to the second place in the world. , A new stage of long-distance power transmission. However, this huge system was so fragile in the face of this sudden ice and snow disaster that it was unbearable to deal with: hundreds of thousands of poles and towers collapsed, several...
