Embodiment Construction
[0021] The mechanical fault diagnosis method for the high-voltage circuit breaker operating mechanism of the power system proposed by the present invention includes the following steps:
[0022] (1) Collect the opening and closing current signals of the high-voltage circuit breaker operating mechanism in the current power system, and establish the first relationship curve between the sampling time and the opening and closing current signals. The abscissa in the first relationship curve is the sampling time, and the ordinate is the opening and closing current value at the corresponding sampling moment, such as figure 1 As shown, among them, T 1 Indicates the moment when the iron core starts to move, T 2 Indicates the moment when the iron core hits the bent plate, T 3 Indicates the moment when the iron core moves to the maximum stroke, T 4 Indicates the opening / closing completion time of the main contact of the circuit breaker, T 5 Indicates the opening moment of the auxilia...
