摘要
针对数字式电动机保护CSL216M反时限过负荷保护难以整定以及如何采用实验方法验证其正确性的问题,提出了反时限发热时间系数τ的四种估算方法,并推导出现场条件下的实验公式,确保电动机的顺利投运。
It is difficult to adjust inverse tim e-lag overload of CSL216M protector for digi-tal motors.It is a problem that how to verify its correctness by using test methods.Four estimat-ed methods for inverse time-lag heating time factorτare given,and test fomulas under in-situ conditions are derived.This assure s successful commissioning of the mo tors.[
