摘　　要：装设故障限流装置是解决日益严重的电网短路电流超标问题的有效技术措施之一。基于智能快速断路器技术、短路电流过零点精确相控开断技术研制了一套330 k V开关型零损耗电网故障限流装置。该装置采用模块化设计方法,在正常运行时损耗为零,短路故障发生20 ms内,可将80 k A及以下的短路电流限制在系统断路器安全开断水平。装置成功在330 k V线路上通过了带电、挂网运行和2次人工单相瞬时短路试验,验证了装置满足安全性、有效性和可靠性的要求。Fault current limiter（ FCL） is one of the efficient technological measures to solve the increasingly serious problem of excessive short-circuit current in power grid. A 330 k V breaker-type zero-loss FCL with modularized design is developed on the basis of intelligent high-speed circuit breakers and short-circuit zero-cross point precise phase controlled breaking technology. Zero-loss of the FCL is obtained under normal condition and up to 80 k A short-circuit current could be limited within 20 ms to the safe breaking level of the system circuit breaker. The security,efficiency and reliability of the device are verified by field operation and two single-phase transient short-circuit experiment in a 330 k V network.
