On line monitoring system of transformer respirator based on wireless sensor network

In order to realize on-line monitoring of the status of transformer respirator, a design method of on-line monitoring system of transformer respirator based on wireless sensor network is proposed. According to the structural characteristics of the respirator, the humidity sensor is used to monitor the working state of the respirator on line. The designed system is divided into humidity sensor module and data processing terminal. Humidity sensor module is responsible for the extraction of state information, data processing terminal is responsible for logic judgment and real-time display and alarm of respirator online working state. The relationship between the state of silica gel in respirator and its humidity value is analyzed, and the on-line monitoring of the state of respirator is realized. At the same time, relevant experiments are carried out to prove the feasibility and effectiveness of this scheme.
