With the development of power grid technology and improvement of equipments. High voltage switch cabinet has been widely used in power system. overheating has become the common problems in the use of switch cabinet. The switch cabinet is mostly closed structure in use. It is dififcult to monitor the temperature of switch cabinet. This paper puts forward a wireless temperature measurement system to collect temperature data in switch cabinet using wireless radio frequency and sensor network technology. A simple and high-efifciency wireless communication protocol was designed and it greatly extends the data transmission distance. This system has strong robustness and the temperature collecting node is low-power. It is suitable for large scale application.
