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

Abstract

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

Description

[0001] (1) Technical field [0002] 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. [0003] (2) Background technology [0004] 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...

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.
