Abstract

The present application discloses a system and method for heat detection and cooling of transmission line clips. By carrying a drone, an infrared thermal imager can quickly obtain an infrared thermal image of a transmission line clip, and a control module can determine the power transmission according to the infrared thermal image. Whether the temperature of the line clamp exceeds a preset temperature threshold, so as to quickly detect the heating condition of the transmission line clamp. At the same time, when the ground remote control platform receives the heat warning information, it controls the spray gun to spray the hollow sphere. When the sprayed hollow sphere hits the transmission line clip, it breaks, and the conductive viscous liquid inside the hollow sphere adheres to the It can quickly enhance the conductivity of the power transmission line clip, so that the resistivity is reduced, thereby reducing the heating temperature of the transmission line clip, eliminating the hidden danger of heating, making it possible to avoid power failure detection and maintenance, thereby reducing small loss.

Description

technical field [0001] The present application relates to the technical field of power transmission equipment maintenance, in particular to a heat detection and cooling system for transmission line clamps and a corresponding method. Background technique [0002] Transmission line clips are used to suspend the ground wire to the hanging insulator string or the connector on the fittings. Since the transmission line is exposed to the wild for a long time, the transmission line is clamped by the wind, rain, and sun of nature, which often causes the transmission line to be damaged. Bad problems such as loose clamp, corrosion or poor contact will cause the transmission line clamp to heat up, which will make the contact resistance of the connection part or the wire joint far greater than the normal value. When the current passes through the connection part, the temperature of the joint will rise due to the increase of resistance at this position. If it is operated under high curren...
