Research on Online Temperature Monitoring System in Medium Voltage Switching Cabinet

Based on the analysis of the overheating fault of the medium voltage switch cabinet, the necessity of online temperature monitoring of the medium voltage switch cabinet is discussed. On the basis of classifying and comparing the main current temperature measuring methods, a set of medium voltage switchboard temperature measuring system is studied. The design idea of each module of the system, the selection and assembly of hardware, the design of wireless transceiver module and PC software are described in detail. The performance of the assembled temperature monitoring system is tested. The experimental results show that the system is reliable and can achieve the purpose of real-time temperature monitoring.
