Title:
MOISTURE ABSORPTION SYSTEM OF OIL-FILLED APPARATUS, AND OPERATION CONTROL METHOD FOR MOISTURE ABSORPTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/205503
Kind Code:
A1
Abstract:
A moisture absorption system of an oil-filled apparatus, the moisture absorption system comprising a main moisture absorber and an auxiliary moisture absorber; the tops of the main moisture absorber and the auxiliary moisture absorber are respectively in communication with a first path outlet and a second path outlet of a two-position three-way electromagnetic valve by means of pipelines; the bottoms of the main moisture absorber and the auxiliary moisture absorber are respectively in communication with a top ventilation opening of a moisture-proof valve by means of pipelines; the inside of the moisture-proof valve is provided with an air suction flow passage and an air discharge flow passage, and two ends of the air suction flow passage and two ends of the air discharge flow passage are respectively in communication with the top ventilation opening and a bottom ventilation opening of the moisture-proof valve; an air suction conduction one-way valve is arranged in the air suction flow passage; and an air discharge conduction one-way valve is arranged in the air discharge flow passage. The moisture absorption system of an oil-filled apparatus has the advantages of being maintenance-free, clean and environmentally friendly, and high reliability. Correspondingly, the present invention also provides an operation control method for the moisture absorption system of an oil-filled apparatus, which method can prevent a situation in which silica gel is treated when same still has a moisture absorption effect or the silica gel is not treated even after the silica gel has lost effectiveness, and makes the reliability of the system high.
