This product utilizes modern industrial sensor technology, adopting a third-party perspective to identify the disconnector's open/close status by determining whether characteristic points such as the disconnector's open/close pointer, crank arm, limit post, open/close indicator, and connecting rod rotating bolt are in position - without interfering with the primary disconnector's movement process - and transmits signals to the station-end measurement and control (remote terminal unit) via a signal transmission path independent of primary equipment.
