Strain clamp drainage plate with temperature control heating automatic shunting and alarm apparatus

Abstract

The invention discloses a strain clamp drainage plate with a temperature control heating automatic shunting and alarm apparatus. The strain clamp drainage plate with the temperature control heating automatic shunting and alarm apparatus comprises a strain clamp drainage plate and is characterized in that a bimetallic temperature measurement sheet is fixed on a bolt fixation plate of the strain clamp drainage plate, and the inner-side wall of the strain clamp drainage plate is provided with a shunting lead wire; the central portion of the shunting lead wire is fixed on the inner-side wall of the strain clamp drainage plate through a plastic clamp; a conduction apparatus is arranged at a position, which bridges over the bimetallic temperature measurement sheet, of the shunting lead wire, and the handle end of the strain clamp drainage plate is provided with an alarm. The strain clamp drainage plate, when being heated to a limited scope value due to a resistance increase, can automatically reduce current intensity, flowing through the strain clamp drainage plate, of a power transmission line so as to reduce the heat productivity of the strain clamp drainage plate; and at the same time, when a continuous temperature rise cannot be controlled through shunting, an alarm is immediately given, maintenance or replacement is carried out through timely manual high-altitude operation, and thus the strain clamp drainage plate is effectively prevented from a burnout accident.

Description

technical field [0001] The invention relates to an improvement of a strain-clamp drainage plate, in particular to an automatic heat-distribution and alarm system with temperature control and heating when the tension-clamp drainage plate of a power transmission line is heated The device's strain clamp drainage plate. Background technique [0002] With the expansion of the grid scale and the continuous improvement of the importance of electric energy to people's life, the society has higher and higher requirements for the reliability of power supply. The transmission line is an important part of the power system, and its reliability plays an important role in the safe and stable operation of the entire power system. The heating problem of the strain clamp drainage plate is an important factor affecting the safe and stable operation of the transmission line. The heating of the diversion plate is caused by the thermal effect of the current. The diversion plate itself has a cert...

Problems solved by technology

Although this design can divert heat and avoid overheating of the strain clamp drainage plate, it also has the following disadvantages: First, it still needs manual climbing operation, which is not only time-consuming and laborious, but also has unsafe factors, and even requires a power outage; second, diversion Wires are dangling, susceptible to wind, cause wobble, and are not aesthetically pleasing
