Technical Field
The utility model relates to a three station isolator technical field in the GIS system especially relates to close improvement of dividing position blocking device to three station isolator drive mechanism.
Background
In 110KVGIS, a three-position isolating switch plays an important role in the whole GIS system. The switch-on position of the connection of the main fracture of the isolating switch, the isolation position of the separation of the main fracture and the grounding position of the grounding side require sensitive, clear and reliable actions, and misoperation is avoided. At present, in the prior art, the locking structures of the closing and opening positions of the transmission mechanism of the three-position isolating switch are various and different. In practical application, the failure rate is high and the reliability is low. Therefore, it is necessary to optimize and develop a new type of separation and combination position locking system to solve the above problems.
