摘要
对未能按ANSI/IEEEC37.1 8标准进行分断能力型式试验的开关 ,可从发电机灭磁对磁场断路器弧能及弧压的要求方面考虑 ,采用按IEC或GB标准进行开关分断能力型式试验时所给出的开关允许承担的弧能及弧压值 ,对该开关用做磁场断路器进行选择。制造商应给出开关在发电机灭磁回路上分断时的弧压上升速度 (或有关数据 ) 。
For the switchgear whose type test of breaking capacity is not completed according to ANSI/IEEE C37.18 standard, the arc energy and the voltage of field circuit breaker (FCB) produced in de excitation can be considered. The parameters of the arc energy and voltage for the switchgear test according to the IEC or GB standard under rated breaking capacity can be used for the selection of FCB. And the arc voltage rise rate (or relative data) of switchgear at breaking should be provided by the producer, so as to be used for the calculation of arc energy of FCB under serious de excitation conditions of generators.
