Passive wireless online temperature monitoring system consists of passive wireless temperature sensor (temperature probe) and wireless concentrator (wireless data receiver). It can be applied to on-line temperature monitoring of various high-voltage distribution equipment, such as bus temperature measurement of mobile indoor switchgear, temperature measurement of insulation plug at cable joint of ring network cabinet, on-line temperature monitoring of high-voltage electrical appliances such as high-voltage transmission lines, high-voltage isolating switch contacts and transformer outlets.
By monitoring the operation of cable heating joint, accidents caused by equipment heating can be effectively prevented; Installing passive wireless digital temperature measurement system is the best choice, which not only ensures the stable and reliable operation of cables in the future, but also facilitates the safety management of equipment and improves the efficiency of power grid operation management.
