CONTROL AND PROTECTION SYSTEM FOR MECHANICAL HIGH-VOLTAGE DIRECT CURRENT CIRCUIT BREAKER, AND CONTROL METHOD FOR SAME

Embodiments of the present application disclose a control and protection system for a mechanical high-voltage direct current circuit breaker, and a control method for the same. The system comprises: an electrical current acquisition and determination module configured to acquire an electrical current parameter in a topological structure of a mechanical high-voltage direct current circuit breaker, and determine, according to the electrical current parameter, whether there is a short-circuit, and feed back a determination result and the electrical current parameter to a central processor module; a voltage information acquisition module configured to acquire a voltage parameter of a converter capacitor in the topological structure of the mechanical high-voltage direct current circuit breaker, and send the voltage parameter to the central processor module; the central processor module configured to send a control instruction to an action control module according to the determination result sent by the electrical current acquisition and determination module and/or the voltage parameter sent by the voltage information acquisition module; and the action control module configured to perform a corresponding action according to the control instruction sent by the central processor module.
