Pattern displacement sensor system for detecting position state of disconnecting link of transformer substation

The invention provides a pattern displacement sensor system for detecting the position state of a disconnecting link of a transformer substation. The system comprises a pattern displacement sensor and a background operation and maintenance system. The pattern displacement sensor is used for collecting angular displacement change signals of the disconnecting link of the transformer substation and transmitting the signals back to the background operation and maintenance system. The background operation and maintenance system compares the received angular displacement change signals with the maximum link closing angle and the minimum link closing angle which are preset in the system, and if the angular displacement change signals are larger than the minimum link closing angle and smaller than the maximum link closing angle, it is judged that the disconnecting link is closed. According to the pattern displacement sensor system for detecting the position state of the disconnecting link of the transformer substation, the position state of the disconnecting link of the transformer substation is automatically detected, the disconnecting link of the transformer substation is remotely patrolled and checked, and a large amount of labor and vigor are saved.
