摘　　要：巴基斯坦T电站机组单机容量大、励磁参数高,对磁场断路器的参数要求也非常高。为了确定磁场断路器的参数要求,给磁场断路器选型设计提供量化理论依据,采用定性分析与定量计算相结合的研究方法,对巴基斯坦T电站可能出现的各种故障类型和相应的灭磁工况,以及各种灭磁工况下的转子电压和转子电流进行了分析、计算和研究,进而确定磁场断路器的参数要求。通过对具有高分断能力的Gerapid 42072X2和CEX 0650004.2开关的比选分析,发现Gerapid 42072X2开关能满足巴基斯坦T电站发电机事故灭磁分断要求。T-station in Pakistan has large generator capacity and high rated excitation parameters,so the parameters of field circuit breakers are also very high.In order to determine the parameter requirements of field circuit breaker and provide a quantitative theoretical basis for the selection and design of field circuit breaker,the research method of qualitative analysis combined with quantitative calculation is adopted to analyze and study various possible fault types and corresponding de-excitation conditions of Pakistan T power station,and calculate the rotor voltage and rotor current under various serious de-excitation conditions,so as to determine the parameter requirements of field circuit breaker.Through the comparison and analysis of the Gerapid 42072X2 and CEX 0650004.2 breakers with high breaking capacity.It is shown that the Gerapid 42072X2 breaker can meet the requirements of de-excitation breaking in case of generator accident for Pakistan T power station.The research conclusion can provide technical support for the equipment selection during the project bidding and the main contract signing.
