Disclosed is a self-heating ice removing system for a high-voltage power transmission line. The self-heating ice removing system comprises a direct current ice removing vehicle, a high-voltage line movable short-circuit vehicle, multiple high-voltage power transmission lines and ice suspension detection units, wherein the direct current ice removing vehicle is used for being movably connected to one end of each high-voltage power transmission line for supplying direct current for the high-voltage power transmission line; the high-voltage line movable short-circuit vehicle is used for being movably connected to the other end of the high-voltage power transmission line for realizing short circuiting of the high-voltage power transmission line; each high-voltage power transmission line is suspended below a power transmission tower through insulators; one ends of the insulators are suspended below the power transmission tower through supporting rods; each ice suspension detection unit comprises a stress sensor configured above the supporting rods of the corresponding insulator; each stress sensor is connected to a central processing unit ECU of the corresponding ice suspension detection unit; and when it is judged that an abnormal value is formed, the central processing unit ECU transmits abnormal information to a base station through a sim card of Internet of Things of a narrow band Internet of Things communication unit. The invention also discloses an operating method of the self-heating ice removing system. The self-heating ice removing system is high in ice removing efficiency, high in automation degree and can save energy.
Description
technical field [0001] The invention relates to a self-heating deicing system, in particular to a self-heating deicing system for high-voltage lines. Background technique [0002] Overhead high-voltage lines are indispensable equipment in the power grid system. It has the characteristics of long transmission distance, high efficiency, and convenient maintenance. At present, overhead high-voltage transmission lines have been widely used for power transmission. However, in winter, when the temperature is below 0 degrees, the high-voltage transmission line will have icing phenomenon, and the weight of the icing can usually be dozens to hundreds of times that of the transmission line, so the high-voltage transmission tower and insulators will bear Huge weight, prone to collapse and breakage. During the 2008 snow disaster, Hunan and Guizhou were particularly affected. [0003] Therefore, deicing of high voltage transmission lines is an urgent technology to be solved. Conventi...
