电流互感器二次绕组的接线有那几种方式？
What are the ways to connect the secondary winding of current transformer?
根据继电保护和自动装置的不同要求，电流互感器二次绕组通常有以下几种接线方式：
According to different requirements of relay protection and automatic device, the secondary winding of current transformer usually has the following wiring modes:
⑴、完全（三相）星形接线；
(1) complete (three-phase) star connection;
⑵、不完全（两相）星形接线；
(2) incomplete (two-phase) star connection;
⑶、三角形接线；
(3) triangle connection;
⑷、三相并接以获得零序电流接线；
(4) connect three phases in parallel to obtain zero sequence current connection;
⑸、两相差接线；
(5) two phase difference wiring;
⑹、一相用两只电流互感器串联的接线；
(6) one phase is connected in series with two current transformers;
⑺、一相用两只电流互感器并联的接线。
(7) one phase is connected in parallel with two current transformers.
