The utility model relates to an outdoor box-type 10kV current transformer, which comprises a high-voltage insulating sleeve, a metal box, a current transformer body, a current transformer secondary winding outlet wire wring board and mounting channel steel. The high-voltage insulating sleeve penetrates through the upper end surface of the metal box to be connected with two ends of a current transformer primary winding outlet wire, a certain spatial distance is kept between the current transformer body and the metal box, the current transformer secondary winding outlet wire wiring board is mounted on the outer side of the lower end of one side of the metal box, and the current transformer body and the metal box are mounted on the channel steel. The outdoor box-type 10kV current transformer is a converter used for 10kV distribution network protection, detection and electric energy metering according to actual needs in distribution network fields, can overcome shortcomings of oil leakage of oil immersed type current transformers and ageing and cracking of epoxy resin pouring type current transformers due to weathering, can increase safe operation of distribution network systems, improves power supply reliability, reduces damage possibility, increases power supply capacity, and further increases enterprise and social benefits.
