Research on the Group-type of High Voltage Electric Field Measurement Safety Distance Caution Apparatus

This paper introduces a kind of research and application of group-type of high voltage electric field measurement and safety distance caution apparatus based on wireless communication technology, the group-type caution apparatus is combined with a master and multiple slaves, in which the slaves are used to measure electric field and the master is used to monitor the slaves. The master keeps the real-time wireless communication with the slaves, realizing the safety dual monitoring of the high voltage working environment and guaranteeing the personnel safety of live working man. Conduct a working performance test on the site of Chongqing Rongchang 500kV Hongban transmission line I about the stability and accuracy. The test results show that the designer of group-type of HV electric field measurement and safety distance caution apparatus can work stably in the strong electric field environment, besides, it has a good performance in both safety distance exceeding alarm and wireless communication.
