Abstract
A hybrid gas-insulated switchgear constitutes an electrical circuit for a single-line diagram unit by arranging one first standardized module and two second standardized modules in a single row such that the central axes of tanks are generally aligned and electrically connecting them to each other. In the standardized modules, a circuit breaker and disconnecting switches are housed inside the tanks such that the disconnecting switches are positioned at first and second ends of the circuit breaker so as to line up generally in a straight line, and grounding switches are connected between the circuit breaker and the disconnecting switches.
