摘要
7UT512型微机变压器差动保护装置是一种新型的继电保护装置,针对该保护装置的现场校验存在的问题,结合现场工作经验和技术说明书,讨论了变压器各侧差动定值的折算关系,以及变压器绕组接线系数的取值。可供继电保护技术人员参考。
The numerical transformer differential protection 7UT512 is a new type relay. Aiming at those problems,combining with work experience and technical description, the relation of coverte between secondary currents into the relay from different sides of the transformer, and the value of CT-ratio, are discussed. It can he reference media of relay protection engineers at jobsite.
