摘　　要：研制了12脉动整流融冰方式、额定输出直流电流5000 A下容量最大的直流融冰系统。根据融冰交流线路参数,对PCS-9590融冰系统设计研制过程中几个比较重要的方面,包括融冰方案、主电路设计、过电压和绝缘配合、控制保护系统等进行较为详细的论述。现场应用表明,直流融冰是解决线路覆冰、缓解冰雪灾害的有效方案。A new DC deicer system with 12-pulse mode and 5000 A rated current is developed. According to the parameters of AC transmission lines, some of its important aspects of PCS-9590 are introduced, including deicing solution, main circuit design, overvoltage and insulation coordination, control and protection system. Field application shows that the proposed DC deicer is an effective solution for the ice-clad problem of AC lines.
