Heating control detection equipment and detection control method of multistrand insulation self-heating wire

Abstract

The invention relates to heating control detection equipment and a detection control method of a multistrand insulation self-heating wire. The multistrand insulation self-heating wire comprises a plurality of outer conductors, a protection metal ring, an insulation and heat conduction ring and a plurality of inner side heating rings. The two ends of the wire are connected with a power transmissionline, and the heating control detection equipment with the same structure is arranged at the connecting ends. The heating control detection equipment comprises a voltage measurement module, a variable resistance module, a wire connecting end, a switch, a microprocessor and a wireless communication module. The heating control detection equipment has different control modes according to three different structures of the inner side heating rings. The microprocessor receives a control command from a control center through the wireless communication module; data of the voltage measurement module is transmitted to the control center, and automatic measurement detection of the wire is performed at the same time. According to the equipment and the method, through current of an internal heating structure and the outer conductors is accurately controlled; a voltage difference of the heating configuration is controlled; the insulation requirement of an insulation layer is lowered; and whether the self-heating wire is normal is automatically measured.

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 detection device and a detection control method for multi-strand insulated self-made heating 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 imp...

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
