摘要
叙述了多种情况下CT二次电压的特征;根据电力系统运行及设计的特点,以原理框图的形式介绍了所研制的CTJW-Ⅱ型CT开路保护装置的原理;用试验实测数据说明其性能指标;根据其设备自身特点,介绍其应用范围及使用方法。希望该CT开路保护装置在电力生产中发挥应有的积极作用。
The paper explains the characters of CT second-coil voltage in many cases, describes the principle of CTJW-Ⅱ CT open-circuit protection circuit by the theory chart according to the properties of power system running and design, analyzes its applied range and used measures on basis of self-trait of equipment, and shows its capability index by test substantive data. The authors hope that CT open-circuit protection installation can play an active role in power system.
