桥式传感器电路在油中溶解气体监测中的应用
Application of Bridge Sensor Circuit in the Oil Dissolved Gas Monitoring
摘要
Abstract
The composition of dissolved gas and concentration analysis for transformer insulation oil is a common method for evaluating the insulation performance of the transformer and determining the fault types. Based on sensor technology, this paper optimizes and designs the insulation of the dissolved gas in the oil content online monitoring system. The system firstly uses a vice sensor to compensate the non-linear error of traditional gathering circuit in order to improve the response characteristics of the sensor and the work performance, and have been put into field operation. The test data analysis results indicate that the system can perfectly reflect the insulation performance status of transformer and achieve early warning, which has a practical engineering application value.关键词
