Claims

[Scope of Claim for Utility Model Registration] (1) Each split core that is to be combined to form a closed magnetic path surrounding an overhead power transmission line is housed in a case, and two secondary windings are wound around the split core. A split type transformer for an overhead power transmission line, characterized in that each one end of the two is electrically connected internally within the case, and each other end is individually taken out of the case through an insulating bushing. (2) The above-mentioned two secondary windings are wound together around one of the split iron cores, and the above-mentioned one ends of the two secondary windings are electrically connected to each other in the case housing the one of the split iron cores. 2. The transformer according to claim 1, wherein the transformer is connected to the case and the other ends of the secondary winding are taken out through two insulating bushings provided outside the case. (3) The above two secondary windings are wound together around one of the split cores, and one end of each of the two secondary windings wound around the one split core is connected to the other end of the secondary windings wound around the other split core. Each terminal of one wound secondary winding is connected to a connecting terminal facing through an insulating bushing to the combined part of each case containing these split cores, and the two above-mentioned two The one ends of the secondary windings are electrically connected to each other via the one secondary winding at the combined part, and the other ends of the two secondary windings are connected to each other through the one secondary winding.
2. The transformer according to claim 1, wherein the transformer is individually taken out through two insulating bushings provided outside the case in which the next winding is housed.
