High-voltage isolation switch for icebreaking through optical energy

Abstract

The invention provides a high-voltage isolation switch for icebreaking through optical energy. The isolation switch is composed of a base, an operating mechanism, a transmission mechanism, an insulation part and a conducting part. The conducting part comprises binding posts, conducting arms, contacts, contact fingers and photo-thermal converters. Each conducting arm is provided with two photo-thermal converters located at the corresponding contact and the corresponding contact finger. The photo-thermal converters are fixed to the conducting arms in a surrounding mode. Each photo-thermal converter comprises a heat collection layer, a heat storage layer, a radiator and a heat insulating layer. The photo-thermal converters can convert solar energy into heat energy under irradiation of sunlight to heat the contacts, the contact fingers and the conducting arms continuously so that moisture around the contacts, the contact fingers and the conducting arms can be prevented from condensing into ice, or little ice can be formed; even if the moisture is frozen, the ice can be molten by being heated; in order to enhance the heating effect, a light condensation vehicle is further arranged as an auxiliary heating device, so that a guarantee is provided for stable operation of a power grid, and losses caused by freezing disasters are greatly reduced.

Description

Technical field: [0001] The invention belongs to the field of electric equipment, and in particular relates to a high-voltage isolating switch, specifically, a high-voltage isolating switch using light energy to break ice. Background technique: [0002] For a long time, in some areas of our country, especially in large and high latitude areas, the winter temperature is very low and the frost time is long. collapse, threatening the operation of the power system and the security of the power grid. In addition, just like the icing on the transmission line during freezing rain, in a very humid winter climate, the contacts and fingers of the high-voltage isolating switch may be condensed and frozen by moisture in the air, making it difficult to open and close, especially when the high-voltage isolating switch When the switch is closed, the contacts should have the ability to break ice at the moment of closing, otherwise the contacts of the isolating switch are isolated by ice an...

Problems solved by technology

This method can only remove a certain thickness of icing, and cause wear and tear on the contacts and fingers. The operating force is large and the rigidity is high. When the icing is serious, the high-voltage isolation switch cannot even be separated or closed.
