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 discloses an electric deicing pick and a deicing method, which comprise an insulating rod and a casing arranged on the insulating rod, a coil is arranged in the casing, an iron core is arranged in the coil, and an iron core is arranged in the iron core. There is a sliding armature, and a return spring is set on the sliding armature. The upper end of the sliding armature is provided with a deicing shovel protruding from the housing, and the housing is provided with a deicing guiding line protection mechanism. The device does not require a power outage during the deicing process, and the high voltage will not cause damage to the operator.

Description

technical field [0001] The invention relates to the technical field of deicing equipment for power transmission lines, in particular to an electric deicing pick and a deicing method. 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 accidents such as line tripping and power supply interruptions. Production and people's lives...
