Meanwhile, the detection mechanism 5 is installed at the corresponding switch 59 position on the indication panel 4, and is used for detecting whether the indication rod 3 and the indication pointer 2 rotate to the switch 59 position or not and transmitting the detection information to the processor 6.
In the actual use process, when the GIS disconnecting link 1 is switched on and off 59, the transmission rod 11 rotates, and the switching of the GIS disconnecting link 1 is controlled through the rotation angle and the position of the transmission rod. When the detection mechanism 5 of the corresponding opening position detects the indicating pointer 2 and the indicating rod 3, the detection mechanism 5 at the position transmits the detected information to the processor 6, and the processor 6 is monitored to detect the corresponding opening information.
