Study on Control Cabinet of Automatic Filtration System for Insulating Oil of UHV Substation

Abstract

Ultra-high voltage substation has a large demand for insulating oil, but the impurities in the oil are required to be regularly filtered out before and during use. However, the existing insulating oil is operated by manpower and it has some defects. For example, it needs a large amount of labor but with low efficiency, and it is difficult to precise control temperature and quality of the oil. This paper introduces a control cabinet for transformer oil filter. It is mainly used in the process of transformer oil filter to achieve the monitoring of liquid level, oil temperature and flow rate, at the same time, to achieve the automatic control of oil filter.
