Abstract

A charged thermal ice-melting device is disclosed, which is composed of a high pressure fan (1) arranged on a hydraulic lift truck (2), an air heater (3) and an insulating wind pipe (6), wherein, an air outlet (4) of the air heater (3) is connected with the insulating wind pipe (6) by using a temperature-resistant hose (5). When charged devices of a transmission power station is iced, high-temperature and high-pressure air generated by the processing of the device is jetted to target through the insulating wind pipe 6. The device 1) can carry out charged thermal ice-melting treatment on equipment architecture below 500kV; 2) can adjust the temperature of the air outlet; 3) can be connected with insulating wind pipes having different lengths; 4) has simple operation and 5) convenient movement; 6) reduces risk; 7) and completely avoids the situation in which ice-melting operation is entirely held up to thereby keep the ice-melting operation unobstructed.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an electrified thermal ice-melting device, which is suitable for ice-melting treatment of high-voltage isolating switches in substations and electrified equipment, so as to avoid equipment damage or ice flashes caused by freezing of power transmission and transformation equipment. Fault. Background technique [0002] In recent years, accidents of equipment damage or ice flashes caused by freezing of power transmission and transformation equipment have occurred frequently. For example, in January 2008, the power grid ice disaster occurred in Hunan Province, China, which caused a large number of power transmission lines to collapse and disconnect, directly economic losses of billions of yuan, and seriously affected the safe operation of the power grid and the normal life of the people. Therefore, when the power transmission and transformation equipment i...
