摘要： A gas-insulated substation comprises at least two transformers arranged side by side on a first floor, gas insulated switching apparatus including disconnecting switches disposed on a second floor at a level different from that of the first floor, and branch bus-bars extending vertically and parallelly from lead boxes which project from facing sides of the respective transformers, the branch bus-bars being connected to the disconnecting switches. The substation further comprises main bus-bars each interconnecting the transformers through the branch bus-bars, i.e. the disconnecting switches, so that a length of the main bus-bar is made to be substantially equal to a distance between the lead boxes projecting from the facing sides of the respective transformers.

摘要： An AC-DC electric power converting station is provided wherein circuit lines consisting of converter transformers/ positive and negative polarity valve structures/ DC reactors/ DC circuit breakers are of L-shape and inverted L-shape. The positive and negative polarity valve structures are so arranged that their surfaces in the longitudinal direction face each other. The converting transformers are arranged along the other surfaces of the positive and negative polarity valve structures in the longitudinal direction thereof. The DC reactors and DC circuit breakers are series-connected in the vicinities of the outputs in the direction of width of the positive and negative polarity valve structures. AC and DC switchgears of gas insulated type are arranged to face each other so that they sandwich the positive and negative polarity valve structures therebetween. Conduit air cables connect the positive and negative polarity valve structures and the AC and DC switchgears.

摘要： A gas-insulated switching apparatus is disclosed which includes a circuit breaker having a breaking section with at least a couple of mutually detachable contacts and a grounded tank containing the breaking section and filled with an insulating gas, the grounded tank being maintained at earth potential. A first bushing is vertically mounted on one side of the grounded tank, the central conductor of the first bushing being connected with one of the contact of the breaking section. A disconnecting switch has insulating gas sealed in it and accommodates a disconnecting section in a tank which is arranged connected to but gas-partitioned from the circuit breaker in an axially extending region of the grounded tank on the other side of the region where the first bushing is mounted. A bushing support tank has insulating gas sealed in it and is arranged so that is connected to but gas-partitioned from the disconnecting switch in an axially extending region of the grounded tank on the side of the disconnecting switch which is opposite to that of the circuit breaker. A second bushing is vertically mounted on the bushing support tank and a grounded switch is arranged inside the bushing support tank in a region which is an axially extending region of the circuit breaker. A lightning arrester is arranged gas-partitioned from the bushing support tank below the axis of the circuit breaker and the disconnecting switch but in the direction of this axis. The lightning arrester is electrically connected to the central conductor of the second bushing inside the bushing support tank.
