Heating control device and control method for multi-strand insulated self-made thermal overhead ground wire

Abstract

Heating control device and control method for multi-strand insulated self-made thermal overhead ground wire. Hot overhead ground wire is a conductor consisting of an outer conductor, a protective metal ring, an insulated heat conductor ring and an inner heating ring. The control device is connected to the A and B ports of the conductor. The inner heating ring adopts one of three different structures: non-insulated conductor structure, insulated conductor structure and insulated optical fiber tube. According to the structure of the inner heating ring, the heating control equipment has two different structures: non-insulated conductor structure and insulated conductor structure. The heating control equipment is connected with the self-made hot overhead ground wire at the A end; In the case of non-insulated conductor structure, the outer conductor is connected to the earth after short-circuiting with the inner heating ring at the B end of the conductor. A switch, a microprocessor and a wireless communication module are also arranged at that terminal B of the conductor when the conductor is insulated. The overhead ground wire heating control equipment controls the heating through the control server, controls the resistance of the inner heating ring, controls the heat generation, and effectively implements the overhead ground wire anti-icing and melting.

Description

(1) Technical field [0001] The invention relates to an anti-icing and melting technology for power transmission lines, in particular to a heating control device and a control method for multi-strand insulated self-made thermal overhead ground wires. (2) Background technology [0002] With the development of society and economy, in the environment of increasing power load applications, the requirements for exposed power lines are getting higher and higher. In the cold winter, the lines in many areas will freeze, causing damage to the lines. When the icing exceeds the bearing capacity of the line, serious accidents such as disconnection will occur. Therefore, deicing of power transmission lines in winter is essential and very important. In the prior art, ice melting technology is constantly improving. Application number CN201610867150.1 "A self-melting ice conductor and ice melting equipment" discloses an online ice melting method for transmission lines. The method impleme...

Problems solved by technology

However, the above two methods do not give a precise current control method

In addition, in the patent published by the application number "CN201810370549.8", the inner conductor has only one conductor, which may not generate enough heat

In addition, the pressure difference between the inner conductor and the outer conductor is not easy to control, resulting in high insulation requirements

What is more realistic is that the above two methods only provide the anti-icing and melting methods for the transmission line conductors, but do not provide the anti-icing and melting methods for the overhead ground wires of transmission lines.
