Abstract

The invention provides a temperature monitoring system of an electrical device connector. The temperature monitoring system comprises a wireless temperature sensor unit and a temperature monitoring unit. The wireless temperature sensor unit comprises a passive wireless temperature sensor, a first wireless signal emitting receiver and a first single-chip microcomputer connected with the passive wireless temperature sensor and the first wireless signal emitting receiver. A temperature monitoring sensing unit comprises a display device, a second wireless signal emitting receiver and a second single-chip microcomputer connected with the display device and the second wireless signal emitting receiver. The wireless temperature sensor unit and the temperature monitoring unit are communicated in wireless mode. The temperature monitoring system of the electrical device connector can reflect temperature changing conditions of a measuring point timely and accurately. Due to the passive wireless temperature sensor, use of connection wires can be avoided, a power supply is not used, and low-cost, safe and reliable monitoring of the temperature of the electrical device connector can be achieved.

Description

technical field [0001] The invention relates to the technical field of temperature monitoring, in particular to a temperature monitoring system for joints of electrical equipment. Background technique [0002] With the improvement of the automation level of China's industrial production, the gradual transition of power equipment from emergency repair after failure to preventive maintenance has become the focus of attention and research in the power generation, supply and consumption industries. During the long-term operation of important equipment such as high-voltage switchgear, busbar joints, and indoor and outdoor knife switches in power plants and substations, surface oxidation and corrosion occur, fastening bolts become loose due to thermal expansion and contraction, and the connection between contacts and busbars is aging. Such problems lead to an increase in the contact resistance at the joints of electrical equipment, and with the rapid development of the national ec...
