Electric current transformer is got to indoor generating line type open -close type

The utility model discloses an electric current transformer is got to indoor generating line type open -close type, including unsteady flow source, insulator and casing, the casing is the open round tube structure in one side, and the unsteady flow source is sealed admittedly through the insulator and split into two semicircle parts in the casing and from the center, and two semicircle parts that the unsteady flow source is cut apart are fixed through steel band and locking head and are become a whole, be provided with 3 draw -in grooves in the generating line hole, insert 1 ohm circle on every draw -in groove. The utility model discloses the mutual -inductor that can open and shut at any time makes it swiftly to overlap on insulated cable conveniently, and can avoid appearing leading to the uneven phenomenon that influences output signal in magnetic field because of punching cable off -centre.
