Abstract: In order to monitor and control the hybrid arc-less HVDCCB, and provide adequate data for equipment selection and fault analysis, this paper firstly introduces the hybrid arc-less HVDCCB which is designed by the State Grid Smart Grid Research Institute. Then a practical monitoring system for high voltage direct current circuit breaker is established according to the required data of the junction temperature of power electronics. The system interface utilizes Labview in the design and can fully record and display the data. In addition, the system can realize the function of high frequency data recording and calculation of the junction temperature of IGBT and diode on line. A series of tests have been conducted to verify the effectiveness of the system.

Key words: HVDCCB, monitoring system, junction temperature, data recording
