According to the position of the transmission shaft 12, the rotating rod 9 on the second table 14 is rotated so that the path of the laser emitted by the opening laser transmitter 1303 is parallel to the path of the laser received by the opening laser receiver 1501. The rotating rod 9 on the first table 1 is rotated so that the path of the laser emitted by the closing laser transmitter 1301 is perpendicular to the path of the laser received by the closing laser receiver 201. The operation is simple, the installation is convenient and easy to implement, and the device has high stability. The opening and closing signal transmitting mechanism 13 is clamped on the top of the transmission shaft 12 without changing the original structure of the high-voltage disconnector transmission mechanism. The height of the device can be adjusted and the angle of the fault diagnosis mechanism can be adjusted. It is suitable for high-voltage disconnectors of different types.
[0030] After the installation is completed, fault diagnosis and debugging are carried out. When the high-voltage disconnector is in the open state, the opening laser receiver 1501 receives the opening signal. When the high-voltage disconnector is in the closed state, the closing laser receiver 201 receives the closing signal. At the same time, the posture sensor device 1305 obtains the rotation angle-time waveform diagram and fits the normal high-voltage disconnector angle-time waveform diagram. The fault diagnosis algorithm is used to identify various faults of the high-voltage disconnector, avoiding the influence of human factors on the results of fault diagnosis and improving the efficiency and accuracy of fault diagnosis.
