Abstract: The necessity of online temperature monitoring of high voltage switchgear are analyzed in this paper, and a comparison is made of the existing temperature measurement methods. Basing on the theory of wireless sensor network and point-to-multipoint communication system, a design scheme of a point-to-multipoint monitoring system for high voltage switchgear is introduced based on the wireless temperature sensor network, including the hardware selection and the design of software and two-way communication protocol. This system has many strong advantages, including low cost, simple structure, convenient installation, low power consumption, simple communication protocol, good stability of data communication, and intuitive interface for the monitoring display. Consequently, it can be used for multi-point temperature measurement of high voltage switchgear in substations.

Key words: high voltage switchgear, on-line monitoring, wireless sensor network, two-way communication protocol, temperature detection, monitoring system
