摘要
不同型号的CSC-326G系列保护装置原理不同,现场通过装设不同型号的该保护装置实现了变压器的主保护和后备保护配合。基于110 kV变电站现场运行情况,探究了CSC-326G系列保护装置的原理,并分析了现场运行中其整定与跳闸的关联情况。
Different models of CSC-326G series of protection devices are designed with different principles.By installing different types of protection devices on site,the main protection and backup protection of transformers can be coordinated.Based on the on-site operation of a 110 kV substation,studies are conducted on the principles of CSC-326G protection devices,and the correlation between its setting and tripping principles in field operation are analyzed.
