Description

A transmission line deicing device

technical field

The invention relates to the research field of auxiliary equipment for power transmission lines, in particular to a deicing device for power transmission lines.

Background technique

Ice covering of transmission lines will cause the following hazards: (1) Damage to towers. If the line is covered with ice too thick, the tower will break due to the overloaded mechanical load. (2) Line tripping. For lines with vertically arranged conductors, when the ice coating on the lower conductor falls off first (the ice coating on the conductor does not necessarily fall off at the same time), the conductor will rise rapidly or jump up and down, causing a short circuit between phases, tripping the line switch and supplying power. interrupt. (3) The insulator string is inclined and the wire is seriously sagging. When the thickness of the ice coating in each span of the line is not uniform, the sag of the wire will change greatly, causing the suspension insulator string to tilt, and the hardware will bear a large horizontal force. In the span with too thick ice coating, it will cause the wire to sag seriously and cause a grounding accident. (4) After the insulator string is covered with ice, the insulation performance will be greatly reduced. When the ice on the hanging insulator string melts, icicles may be formed, which will short-circuit the insulator string and cause a grounding accident.

The main methods of de-icing are as follows:

Thermal ice melting method:

At present, there are three common thermal ice melting methods: overcurrent ice melting method, short-circuit current ice melting method, and DC ice melting method. Now 110kV and above lines mainly use DC ice melting. However, this method requires complex equipment and lines, has a high cost, and is more difficult to implement in mountainous areas.

natural de-icing

Natural deicing method refers to the method of deicing by natural force without external energy. For example, a snow-blocking ring, a counterweight and other devices are installed on the transmission line. When the snow or ice reaches a certain level, it will fall off by itself with the help of wind and gravity. This deicing method is simple and easy to implement, but it has strong contingency. , can not achieve reliable deicing, deicing effect is poor.
