Description

Technical Field

[0001] The present invention relates to the technical field of disconnecting devices, and more particularly to a fault disconnecting device. Background Art

[0002] Fault disconnect devices are generally used more in areas with a lot of hydropower and renewable energy power generation. When the power system experiences accidents such as out-of-step oscillation, frequency collapse or voltage collapse, the power system will be automatically disconnected in a planned and appropriate manner at a pre-arranged appropriate location, or the power plant and the associated appropriate loads will be automatically disconnected from the main system to quell the oscillation or ensure uninterrupted power supply to important loads.

[0003] The utility model patent application, published as CN 221530613 U, discloses a power generation system fault disconnection device, comprising a housing, a door on one side of the housing, a lock on the inside of the door, a self-locking block on the inner wall of the housing corresponding to the lock, a sliding block on the self-locking block, a clamping head on the upper portion of the sliding block, a semicircular block on the sliding block, one side of the semicircular block connected to a connecting rod, a protrusion on the lower portion of the connecting rod, a spring on the other side of the semicircular block, a lower limit block on the bottom of the spring, and an upper limit block on the upper portion of the lower limit block; an access port on the lower portion of the door, an output port corresponding to the access port on the side opposite the door; a fixed block inside the housing, a support plate on one side of the fixed block, and a data analyzer and controller on the support plate. This utility model adopts the above-mentioned structure to provide a power generation system fault disconnection device that is simple to operate and highly practical.
