Silicone drying device and control method for transformer respirator

Abstract

The invention discloses a silica gel drying device and a control method for a transformer respirator. The drying device includes a shell, an upper heat pipe, a lower heat pipe, a heat preservation box, an electric heating wire, and a heating circuit. The heat preservation box and the heating circuit are located in the shell. The heating wire is located in the heat preservation box, one end of the upper heat pipe communicates with the upper interface of the respirator silica gel cup, the other end of the upper heat conduction pipe communicates with the upper part of the heat preservation box, and one end of the lower heat conduction pipe communicates with the respirator silica gel cup The lower interface of the lower heat pipe is connected, and the other end of the lower heat pipe is connected with the lower part of the heat preservation box. The heating circuit includes a rectifier bridge D, a voltage stabilizing capacitor C, a power field effect tube Q1, a control unit 8, a power drive unit 9, a temperature Sensor 10, the present invention can dry and dehumidify the silica gel used for drying in the respirator during the operation of the transformer respirator, so that the process of replacing the silica gel can be avoided, which not only ensures the normal operation of the transformer, but also reduces operating costs and improves work efficiency.

Description

Technical field [0001] The invention relates to a transformer, in particular to a silica gel drying device and a control method for a transformer respirator, and belongs to the technical field of power equipment. Background technique [0002] The transformer respirator in the substation is an important part of the transformer. In the daily operation and maintenance process, the desiccant in the respirator must be able to dehumidify, and the silica gel used for dehumidification in the respirator must be replaced. The existing replacement During the process, you need to unscrew the silicone cup, unscrew the oil cup, pour out the original silica gel, inject new silica gel, and finally screw the silicone cup and the oil cup back to their original positions. The whole process should last at least half an hour, and there is If the sealing effect is not good, the oil cup and silicone cup may also be damaged. If the silica gel used for drying in the respirator can be dried and dehumidif...
