Intelligent refueller for assisting in gas filling

Abstract

The invention discloses an intelligent refueller for assisting in gas filling. The intelligent refueller comprises a refueller body, wherein a control board, an oil pump, an air compressor pump and analternating current motor are mounted in the refueller body; the alternating current motor is electrically connected with the control board by a frequency converter; an electromagnet A which is connected with the control board and controls power connection of the air compressor pump and the alternating current motor is mounted on the air compressor pump; a gas filling port respectively connectedwith an oil drum and a breathing tube of a transformer is formed at a gas outlet end of the air compressor pump; a gas pressure sensor connected with the control board is mounted on a gas outlet tubeof the air compressor pump; an electromagnet B which is connected with the control board and controls power connection of the oil pump and the alternating current motor is mounted on the oil pump; anoil pressure sensor connected with the control board is mounted on an oil outlet tube of the oil pump; and a refuelling port connected with an oil filling port of the transformer is formed at the endpart of the oil outlet tube. The intelligent refueller is simple in structure and convenient to operate and popularize, and achieves technical effects of controlling a refuelling process, saving oil consumption, and performing exhaust positioning on a bellows oil conservator.

Description

technical field [0001] The invention relates to the field of oil replenishment tools for transformers, in particular to an intelligent fuel oil dispenser with auxiliary inflation. Background technique [0002] The oil transformer is an important equipment in the power system. After a long time of operation, the transformer body and the transformer oil in the load will be reduced to varying degrees; for the transformer of 35kV and above, the existing oil replenishment method has great disadvantages, such as direct dumping high-altitude operation, high risk, low oil charging efficiency, direct drive pump oil replenishment oil pressure, flow uncontrolled, easy oil injection, oil spillage and even damage to the oil pillow during the oil replenishment process, the vacuum oil filter equipment is huge, and the preparation time It is long and wastes oil, and the oil conservator commonly used in the main transformer is a bellows type, which needs to be filled with oil and exhausted, ...
