Analysis of Parameters for Breaking Performance of Marine Medium Voltage AC Circuit Breakers

According to the characteristics of marine medium voltage power system,the parameters closely related to the breaking performance of medium voltage AC circuit breaker were analyzed.It is shown that the key performance parameters in land standards,such as rated breaking current,making current,power frequency recovery voltage,transient recovery voltage,electrical life and so on,basically meet the marine requirements after conversion.But there are also some individual parameters need to be studied further to decide.
