Description

Technical Field

[0001] This application belongs to the technical field of transformer breather repair and maintenance equipment, and particularly relates to a portable transformer breather restoration device. Background Technology

[0002] A transformer breather is a terminal device used in the voltage regulation system of various enclosed transformers. It ensures the dryness of the gas entering the transformer and prevents moisture and other contaminants from entering. The breather contains silica gel granules for dehumidification and water absorption. After a period of use, the silica gel inside the breather will gradually absorb water and change color. It needs to be collected and processed periodically to recover and restore the discolored silica gel granules for reuse. The basic structure of the silica gel breather is shown in the attached instruction manual. Figure 1 As shown, when replacing silica gel, the oil cup 9b needs to be unscrewed first, then the fastening bolt 7a needs to be removed, followed by the air guide tube 7b. The entire respirator needs to be removed by holding it against the respirator base 9a before replacement. During the replacement process, the respirator's front valve needs to be temporarily closed or a temporary filter device connected, making the operation quite cumbersome. The traditional method is to replace all silica gel particles at once. However, in standard operating procedures, replacement is often not performed after all silica gel particles have absorbed water and changed color. Instead, replacement is performed when half or even less of the silica gel particles in the respirator have absorbed water and changed color. Furthermore, the general approach requires disassembling the entire transformer respirator, which is heavy and inconvenient to operate. All silica gel particles need to be completely emptied before replenishment or backfilling, leaving most of the silica gel particles unused. Refilling also incurs additional labor costs and unnecessary workload. Summary of the Invention
