Abstract: Description was made to the multiple test circuits and the test conditions of high-voltage circuit breakers in carrying out out-of-phase making and breaking test and comparison was made to their advantages and disadvantages. According to the actual test conditions in test station, this paper selected transformer double-circuit which is convenient to carry out and parallel voltage injection circuit and calculated parameters of 126 kV level test loop. Simulation was carried out for the relevant transient recovery voltage waveforms. The result is in conformity with the expected requirements, so it can be implemented.
Key words: high-voltage circuit breaker; out-of-phase making and breaking test; transformer double circuit; parallel voltage injection circuit; transient recovery voltage waveform simulation
