| 摘 要： | 目前用于发电机灭磁系统的国外磁场断路器可分为两类，一类按ANSI/IEEE C37.18的标准定义，另一类按照ANSI/IEEE C37.14或IEC77标准试验定义。分析比较了两类不同标准要求下的磁场断路器的型式试验报告，并就UR40M-64S型磁场断路器在二滩水电站的具体应用进行了计算分析。结果认为二滩水电站在极端工况下磁场断路器可以安全可靠分断，这些分析判断对其他电站进行磁场断路器的安全分析和评价有一定的借鉴作用。

| Abstract: | Foreign field circuit breakers used for de-excitation system of generator can be divided into two types;one is defined according to ANSI / IEEE C37.18 standards and the other one is in accordance with ANSI / IEEE C37.14 or IEC77 standard test.We analyze and compare the reports on type tests of the field circuit breaker under the two different standards,and calculate and analyze the UR40M-64S-type field circuit breaker in the specific application of the Ertan Hydropower Station.It was shown that the field ci... |
