The invention relates to a GIS type semi-pouring external current transformer and GIS equipment. The GIS equipment comprises a GIS type semi-pouring external current transformer; the GIS type semi-pouring external current transformer comprises a straight-through bus shell and a current transformer outer cover; the straight-through bus shell and the current transformer outer cover form a cavity foraccommodating a coil; a sealing insulator is poured at the joint of the straight-through bus shell and the upper portion of the current transformer outer cover; a flow guide cover is installed on thecurrent transformer outer cover; an elastic sealing piece arranged in an annular mode is arranged between the upper portion of the sealing insulator and the straight-through bus shell or the currenttransformer outer cover; and the sealing piece and the sealing insulator are matched in a sealing mode in the radial direction of the straight-through bus shell. With the GIS equipment adopted, the problem that the measurement
