Description

Deicing device and deicing method for wall bushing of current transformer

Technical Field

The invention relates to the technical field of through-wall bushing deicing, in particular to a through-wall bushing deicing device and a through-wall bushing deicing method for a current transformer.

Background

As is known, the current transformer principle is based on the electromagnetic induction principle. The current transformer is composed of a closed iron core and a winding. The primary side winding of the current transformer has few turns and is connected in series in a circuit of current to be measured, so that all current of the circuit always flows through the current transformer, the secondary side winding has more turns and is connected in series in a measuring instrument and a protection circuit, and when the current transformer works, the secondary side circuit of the current transformer is always closed, so that the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to short circuit. The current transformer converts a large current on the primary side into a small current on the secondary side for use, and the secondary side cannot be opened. The high-voltage wall bushing is an important device of a high-voltage transmission system and is a core component for high-voltage lead insulation, and the performance and quality of the high-voltage wall bushing play an important role in insulation isolation and link transition when a line penetrates through a wall. If the high-voltage wall bushing is damaged due to electric breakdown or insulation flashover, the insulation of the wall bushing is damaged, and other equipment and power operation of a high-voltage power transmission system are seriously damaged. At present, snow removing methods of high-voltage wall bushing mainly comprise manual snow removal, wind power snow removal by a fan and the like. Wherein, the manual snow removal is required to be finished under the power failure working condition, and the potential personal safety hazard is easily caused; and snow removing efficiency of wind power snow removal of the fan is low, so that snow is not fast cleared.

The invention is disclosed in China: CN106786123A discloses a device and a method for removing snow and ice from a wall bushing, wherein the device adjusts the irradiation power of a radiation lamp to better dissipate heat to melt a snow layer or an ice layer on the wall bushing, thereby greatly improving the efficiency of removing snow and ice, but the device has lower efficiency for removing ice and snow from the wall bushing exposed outside the wall, and the device uses the radiation lamp to bake, so that the method is single and the efficiency is lower, therefore, the device and the method for removing ice from the wall bushing for a current transformer are provided.
