Problems solved by technology

Although the above-mentioned traditional ice-melting devices can melt ice, what they don’t know is that: the ice-melting device is easy to cause damage to the high-voltage transmission line, and more importantly, it needs to be powered off first, and then the above-mentioned equipment is installed in the On the power transmission line, it usually takes at least 70 minutes of power outage, and then pushes the gate to send power. After deicing, the above-mentioned equipment needs to be removed after the power outage, and power needs to be sent again, which is time-consuming and labor-intensive, seriously affecting the stability of power supply

Abstract

The invention provides a non-power cut deicing device for electromagnetic looped network loop closing operation. The deicing device comprises an insulation rod and a shell arranged on the insulation rod; a driving motor is arranged in the shell; a rotating shaft of the driving motor is provided with an eccentric wheel driving a deicing shovel to move up and down; the upper portion of the shell is provided with a guide righting sleeve allowing the deicing shovel to move up and down; the shell is provided with a deicing guide line protecting mechanism. There is no need to cut off power when the device is used for deicing and injuries caused by high tension electricity to operating staff are prevented.

Description

technical field [0001] The invention relates to the technical field of deicing equipment for transmission lines in closed operation of electromagnetic ring network, in particular to a deicing device for power failure in closed operation of electromagnetic ring network. Background technique [0002] With the rapid development of my country's electric power industry, the coverage area of ​​high-voltage transmission network continues to expand, and the lines pass through different geographical environments. Some areas often encounter low temperature, ice, snow or freezing weather. However, since the atmospheric temperature is lower than zero and the air humidity is relatively high, the melted ice will quickly condense into ice, making the speed of freezing faster than the speed of melting, resulting in more and more ice. Severe icing of high-voltage lines will lead to collapse of towers, wire galloping, disconnection, insulator flashover and de-icing jumps, etc., causing acciden...
