BUSHING UNIT FOR DISTRIBUTION APPARATUS AND FITTING STRUCTURE FOR BUSHING UNIT

摘要

PURPOSE: To miniaturize a bushing unit for a distribution apparatus and prevent the bushing unit from being broken, e.g. being cracked. CONSTITUTION: A bushing main body 3, a flange section 4, and insulating ribs 5 are integrally molded with silicone rubber. A zero-phase current transformer 6 is buried in the flange section 4, and a sealing protruded stripe 23 is integrally formed on its lower face. Three-phase insulated electric wires 11a-11c are inserted into the bushing main body 3. Connecting conductor sections 13a-13c are arranged in the middle of the insulated electric wires 11a-11c, and the copper core wires of the insulated electric wires 11a-11c are caulked in the insertion holes 14 formed at both ends of the connecting conductor sections 13a-13c. The insulated electric wires 11a-11c are hooked by interval holding plates 15a-15c to be located at the vertexes of a triangle on the cross section of the bushing main body 3.
