| Abstract: | The article introduces the principle of earthing transformer, working characteristics, as well as the earthing transformer in the practice of rail transit power supply system. From the three aspects of protection of the operating reliability, flexibility and safety of the system operating mode change, as well as construction costs, two different kinds of wiring for earthing transformer are analyzed and compared. From the daily operation and maintenance aspects, separate circuit breakers for earthing transformer are proposed. |
