Summary: | The invention discloses a method for detecting the electrical condition of a high-voltage circuit breaker, and relates to the technical field of electrical condition detection. The method comprises the following steps: S1, detecting a mechanical vibration signal of the high-voltage circuit breaker; s2, detecting and analyzing the current waveform of the opening and closing coil based on a detection circuit; s3, detecting the stroke of the high-voltage circuit breaker based on a photoelectric stroke sensor; s4, detecting the breaking current based on the detection circuit; s5, level signal detection is carried out on opening and closing based on a certain period time; s6, detecting a closing spring based on a pressure sensor; s7, detecting a loop resistance change curve of the high-voltage circuit breaker; and S8, the existing fault problem is reported and maintained in time. According to the electrical condition detection method for the high-voltage circuit breaker, early-stage defects of the transformer can |
