[Technical background of the invention...] In substations or switchyards installed around large cities or coastal areas, the electrical equipment that makes up the substation or switchyard is A gas insulated switchgear is used, which is sealed with an insulating medium such as SF6 gas. This type of gas-insulated 13Vl closed equipment is becoming increasingly high-voltage and large-capacity as the demand for electricity increases in urban areas, and the need for further miniaturization, improved reliability, and simpler maintenance is required. ization is required. Therefore, it is necessary to arrange circuit breakers, disconnectors, and other necessary equipment three-dimensionally. C,
The space between each piece of equipment has been narrowed to significantly reduce the site area. At the same time, in order to stabilize the power transmission system, these power transmission substations employ a so-called double bus system in which there are two busbars. In order to lead out the power transmission system from the two-car busbar to the overhead power transmission line, a gas-insulated switchgear using an appropriate number of circuit breakers or disconnectors according to the capacity of the power transmission line is used.
