专利名称：ON-LOAD TAP CHANGER 发明人：MATSUI SHINICHI,OGAWA MASASHI 申请号：J P 14 563888 申请日：19880615 公开号：JPH01315113A 公开日：19891220
摘要：PURPOSE:To simplify a structure and to enhance reliability by a method wherein a driving force is transmitted from a motor-driven operation mechanism to a speedreduction mechanism of a tap selector, is branched off by means of a gear mechanism for conversion of a transmission-shaft direction and is transmitted to a changeover switch. CONSTITUTION:A turning force of an electric motor is transmitted to a worm gear mechanism 7 via a first transmission shaft 4, a first bevel gear mechanism 5 and a second transmission shaft 6 one after another. The turning force whose speed has been reduced with the same worm gear mechanism 7 is branched by means of a second bevel gear mechanism 8; one part of a branched turning force is transmitted to a cam, for traveling contact drive use, of a tap selector 1 via a driving shaft 9 and executes a make-and-break operation of a traveling contact. The other part of the branched turning force is transmitted to a changeover switch 2 via a third transmission shaft 10, a third bevel gear mechanism 11 and a driving shaft 12, and executes a make-and-break operation of a traveling contact of a shaft part. By this setup, a structure can be simplified and reliability can be enhanced.
