摘要
以0LKQ 380 V母线为主要对象,研究其在多种运行方式下发生短路时产生的极限短路电流,并对其进行整定计算,然后对已有的整定结果进行校验,验证整定结果的正确性和合理性。
Taking the 0LKQ 380 V bus as main object,the limit short-circuit current generated when short-circuit occurs under various operation modes is studied,and its setting calculation is carried out.Then the existing setting results are tested to verify the correctness and rationality of the setting results.
