Abstract
The utility model provides a novel frequency converter equipped with a power frequency by-pass, and the novel frequency converter does not influence operation of a water pump and a nuclear power station. The novel frequency converter equipped with the power frequency by-pass comprises a high voltage frequency converter, wherein an input terminal of the high voltage frequency converter is connected with a high voltage line through a high voltage circuit breaker of the high voltage line, the high voltage line is provided with a user switch, an output terminal of the high voltage frequency converter is connected with the water pump through a high voltage circuit breaker of the water pump, and a branch circuit of the high voltage frequency converter is connected in parallel with a power frequency high voltage circuit breaker and an indicator light. According to the novel frequency converter equipped with the power frequency by-pass, the high voltage circuit breaker which is taken as a switch is additionally arranged at two ends of the high voltage frequency converter to form a high voltage frequency conversion branch circuit, and the power frequency branch circuit is connected in parallel with the high voltage frequency conversion branch circuit, so the high voltage frequency conversion branch circuit supplies power for the circulating water pump in a normal condition to guarantee normal operation of a station, and when appropriate adjustment of arrangement of a process system is carried out, electric energy production does not reduce because of a fault of the high voltage frequency converter.
