The invention relates to an intelligent substation prefabricated cable connector, and in particular relates to an intelligent substation current test type anti-misoperation prefabricated cable connector. The connector comprises a current transformer side socket panel, a secondary device side socket panel and a prefabricated cable which connects two socket panels. Plugs are arranged on both ends of the prefabricated cable. Each socket panel comprises a number of panel terminals and lateral connection pieces. A number of panel terminals are divided into groups. Each group comprises two adjacent rows. Each lateral connection piece connects two panel terminals of different rows, wherein the panel terminals are in the same group and share the same phase. According to the invention, a conventional design idea which has a technology bias for a long time is broken through; an indirect connection mode is used; current loop prefabricated connection is realized; the requirements of a current loop test are met; plug and play of current loop wiring are realized; and the operational workload of a substation is greatly reduced.
