Wireless Temperature Monitoring Early Warning System For Substation And Its Application In Zhongshan Power Supply Bureau

The high voltage switch cabinet of substation in the process of long-term operation,because of aging, loose and poor contact, contact in the switch cabinet and busbar, the cablejoint parts be able to be fever phenomenon. The temperature of the heating parts often unableto continuously monitor, which may lead to accidents. By monitoring the important electricalequipment running status of each point temperature can effectively prevent accidents. Currentmethods is shown temperature wax, infrared thermometer, infrared imaging method fortemperature measurement, but due to the limitation of site condition, these methods cannotreal-time temperature monitoring for each key point.In order to the real time control of the equipment running state in the the high voltageswitch cabinet, the power supply bureau of zhongshan set up the technology project"substation equipped with wireless temperature monitoring and early warning system". Thistopic combined with the technology project.According to the characteristics ofhigh voltageswitch cabinet，the existing deficiencies of temperature measurement technology wereanalyzed. The design of wireless temperature measurement system of high voltage switchcabinetbased on surface acoustic wave technology was proposed. Temperature of contactorcan be monitored by the system during the whole working process of high voltage switchcabinet.Signal acquisition is stable. The communication among thermometer, wirelesstemperature monitoring points and the host computer works in good condition. This design iscapable of ensuring stable operation of high voltage switch cabinet,and unifying themanagement of monitor station...
