An intelligent online fault-proofing protection system essentially consisting of an intelligent controller (1), a circuit-switch dolly locking device (2), a cabinet-door locking device (3), a grounding-switch locking device (4), and a high-voltage live-line sensor (5) and indicator (6). The intelligent controller (1) is connected to the circuit-switch dolly locking device (2), the cabinet-door locking device (3), the grounding-switch locking device (4), and the high-voltage live-line sensor (5) and indicator (6), respectively, by means of a circuit. The present invention eliminates from mechanically interlocked fault-proofing apparatuses hidden safety risks such as electrical shock, inadvertent entry into a live space, and closure of a grounding switch in the presence of a live line; allows for continuous online monitoring of the actions of work personnel; prevents accidents from happening and ensures safety for power companies; and can be used independently or can be used as a backup for mechanically interlocked fault-proofing apparatuses. |
