Title:

CASCADED FULL-BRIDGE HIGH-VOLTAGE DC CIRCUIT BREAKER, QUICK RECLOSING METHOD, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2017/050103

Kind Code:

A1

Abstract:

An improved cascaded full-bridge high-voltage DC circuit breaker, a quick reclosing method therefor, and a storage medium. The improved cascaded full-bridge high-voltage DC circuit breaker comprises a main through-flow branch, a transfer current branch, and an energy absorption branch. The main through-flow branch comprises mechanical switches (K) connected in series and a full-bridge module circuit. The transfer current branch comprises at least two full-bridge module units connected in series. The energy absorption branch comprises a lightning arrester. Compared with the prior art, the present invention can achieve quick reclosing of the cascaded full-bridge high-voltage DC circuit breaker within several milliseconds.
