Abstract The dielectric recovery characteristic is an important reference for developing the breaking strategy of a new hybrid current limiting circuit breaker and designing its commutation parameters. In this paper, a synthetic test platform was built, and the dielectric strength recovery characteristics of 45mm diameter CuCr50 butt contacts vacuum interrupter were tested under the conditions of DC current of 20kA, short arcing time and short motion gap. In the process of separating the contacts at an average speed of 3m/s, for different arcing time, overvoltage with an ascending rate of approximately 400V/μs is applied at different times after the current artificial zero-crossing at a rate of about 220A/μs to obtain the relationship between dielectric recovery characteristic and the arcing time. The experimental results show that the gap recovers to its ultimate breakdown voltage at a very fast speed in the arcing time of 100μs. The dielectric strength of the gap fails to be recovered for a long time when the arcing time increases to 320μs. If the arcing time continues to increase, whether the gap is broken down has instability. Therefore, the design principle of the circuit breaker is obtained: during the arcing time of 100ms, increasing the arcing time can increase the contact opening distance and increase the voltage tolerance margin of vacuum interrupter after current zero-crossing.

Key words： Hybrid current limiting circuit breaker artificial current zero short arcing time vacuum dielectric recovery
