FAULT DETECTION METHOD FOR HIGH-VOLTAGE DIRECT CURRENT CIRCUIT AND HIGH-VOLTAGE DIRECT CURRENT CIRCUIT

摘要

A fault detection method for a high-voltage direct current circuit and the high-voltage direct current circuit. The method comprises: acquiring, when a part to be detected is in a state of being disconnected from remaining parts of a high-voltage direct current circuit, a first resistance value of an output end of the part to be detected and a second resistance value of an output end of the high-voltage direct current circuit; and determining, on the basis of the first resistance value and of the second resistance value, a fault state of the part to be detected and of the remaining parts of the high-voltage direct current circuit. The method allows the precise determination of a specific part that is faulty.
