<p>PROBLEM TO BE SOLVED: To obtain a gas insulated switchgear which enables it to reduce the size of an anchoring steel mechanism, to curtail supporting insulators and lead-in wires, and to reduce the installing area of a site needed for a substation. SOLUTION: Two sets of bushings 12, 13 which are led out between gas insulation bus bars 1, 2 or among extension lines of the gas insulation bus bars 1, 2 respectively, from each junction among circuit breakers of three circuit breakers 3-5 arranged between a pair of gas insulation bus bars arranged in parallel at specified intervals and connected in series for connecting the gas insulation bus bars 1, 2 to each other, are provided. Furthermore, the two sets of bushings 12, 13 and transmission lines 24, 25 are connected approximately immediately below transmission line anchoring steel mechanisms 30 provided at the end parts of the transmission lines 24, 25.</p> |
