<p>PROBLEM TO BE SOLVED: To reduce an outer diameter of a transformer for combined gas- insulated lightning arrester and grounding tstrument as well as overall size of a GIS apparatus to which it is attached, by reducing the diameter of a metallic container. SOLUTION: A VT content element 4 is vertically arranged on the bottom of a metallic container 9, and a supporting plate 13 is formed on its upper part and LA content elements 7a, 7b and 7c are vertically arranged on the supporting plate 13. The high-voltage winding 2 of a VT content element 4 is connected with the LA content element 7b by means of a U-shaped entending connection conductor 10. Thus, the VT content element and LA content element of the gas insulated LA-VT are vertically arranged on the upper and lower sides, so that the diameter of the metallic container housing them can be reduced.</p> |
