Abstract :
The test device of electrical contact performance of circuit breaker terminals is firstly developed in the paper, by which electrical contact performance of terminals can be automatically analyzed. Meanwhile, the electrical contact performance of circuit breaker terminals in the environment containing SO2 is studied by measuring the contact resistance of terminals in the conditions of different sulfur dioxide concentration within the same corrosion time and the same sulfur dioxide concentration within the different corrosion time.
