SWITCHGEAR UNIT CONNECTING STRUCTURE AND ITS TESTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a connecting structure between switchgear units capable of easily adding a new unit without removing an insulated bus bar or the like connecting between existing units when adding a switchgear unit. SOLUTION: Cross joints 4 which are provided with an insertion port of an insulated bus bar 3 disposed at and connected to both ends in a direction crossing a switchgear unit conductor, are respectively provided on a tank 1 of the unit. A switchgear unit connecting structure is formed by consecutively connecting cross joints via the insulated bus bar 3. An insulating cap is inserted in the insertion port on the side opposite to the insulated bus bar at the termination of the consecutively connected cross joints so that the port is sealed.
