Ice coagulation preventing cable and auxiliary equipment

Abstract

The invention relates to an anti-icing cable applicable to ice rain atrocious weather and matched auxiliary facilities with anti-icing property. The anti-icing cable of the invention is characterized in that the cable is sleeved with an anti-icing sleeve, a clearance is reserved between the inner surface of the anti-icing sleeve and the surface of the cable, and the anti-icing sleeve can rotate relative to the cable. An insulating bottle for field power transmission is characterized in that the easy-icing surface of the insulating bottle is provided with the anti-icing sleeve. An anti-icing field metal tower body is characterized in that the surface of an easy-icing part of the tower body is provided with an anti-icing element. A method for arranging the anti-icing sleeve or the anti-icing element on the easy-icing part of the cable, the insulating bottle or the tower body effectively prevents the surface from icing, greatly reduces the heat exchange with the outside, and effectively prevents the icing phenomenon caused by heat absorption after rainwater is directly contacted with the cable, the insulating bottle or the tower body.

Description

technical field [0001] The invention relates to an anti-icing electric wire or cable suitable for freezing and rainy weather, and auxiliary facilities with anti-icing characteristics used together with the electric wire or cable. Background technique [0002] Since China has a vast land area and spans multiple temperature zones, the temperature varies greatly from province to province, and rain and snow disasters occur from time to time. Judging from the 2008 rain, snow and freezing disasters in southern China, when the air temperature near the ground is below zero and the air at high altitude is relatively warm and freezing rain or snow falls, the raindrops or rain and snow hit the cold power lines, iron towers or When insulating bottles, because these objects are good conductors of heat, they can quickly conduct the heat in the rainwater and release it to the surrounding cold air, or in other words, quickly guide the coldness of the object itself and the coldness in the su...

AI Technical Summary

Problems solved by technology

For wireless signal transmission towers and their signal transmitters, there is also the problem of ice condensation. Once ice condensation occurs, the signal transmission will be affected at the slightest, and the tower will collapse if it is severe.

There is also the problem of icing on the transmission lines, transmission poles and tension lines of electrified railways. Once icing occurs, it will affect the power supply at least, and cause the wires to break if it is serious.

[0003] These natural disasters endanger the national lifeline projects, which will not only cause huge economic losses, but also bring great inconvenience to people's lives, and even endanger people's lives in severe cases.
