An intelligent fuel dispenser with auxiliary inflation

Abstract

The invention discloses an intelligent oil dispenser for auxiliary inflation, which includes a body in which a control panel, an oil pump, an air compressor and an AC motor electrically connected to the control panel are installed through a frequency converter. The electromagnet A connected to the power of the air compressor and the AC motor, the air outlet of the air compressor is provided with an air charging interface connected to the breathing tube of the oil tank and the transformer respectively, and the air pressure sensor connected to the control board is installed on the air outlet of the air compressor The oil pump is equipped with an electromagnet B connected to the control board and controlling the power connection between the oil pump and the AC motor. An oil pressure sensor connected to the control board is installed on the oil outlet pipe of the oil pump, and a charger connected to the transformer is installed on the end of the oil outlet pipe. Filling interface for oil port connection. The invention has a simple structure, is easy to operate and popularize, and achieves the technical effects of controlling the refueling process, saving oil, and performing exhaust positioning on the 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 filling efficiency, oil pressure of direct drive pump oil replenishment, flow uncontrolled, easy oil injection, oil spillage or even damage to the oil pillow during oil replenishment, vacuum oil filter equipment is huge, and 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, and the refueling i...
