Intelligent Control System of Vacuum Oil Filter Based on PLC

Abstract

This paper proposed an intelligent control system of vacuum oil filter based on PLC. The system aims to enhance the automatic control and remote monitoring capabilities of Vacuum Oil Filter. With the S7-200 PLC serving as the control center, it incorporates state-sensing and electronic control components into the critical areas of the vacuum oil purifier. This allows for precise control of the degassing hood's liquid level, detection of insulating oil leaks, and automatic control of the condensation tank. Consequently, the system enables unmanned filtering of insulating oil, demonstrating its practicality.
