摘要： A circuit breaker includes a tank grounded and filled with an insulating gas, a first electrical series-connected section having a main conductor and a main breaking section, and a second electrical series-connected section having a resistor and an advance closing contact device. The first electrical series-connected section is coupled electrically in parallel to the second electrical series-connected section. The fixed contact side of the main breaking section is supported by an insulating cylinder and the fixed contact side of the advance closing contact device is supported by an insulating plate from the fixed contact side of the main breaking section. A breaking unit, chiefly composed of the main breaking section and the advance closing contact device, is supported by insulating cylinders. A resistor unit is supported by an insulating cylinder. The assembly of each of the units can be performed completely outside the tank, thereby eliminating the need for performing any adjustment type of work within the tank.

摘要： The gas-blasted circuit-breaker includes a movable arc contact, a fixed arc contact opposing the movable arc contact, an insulating nozzle, a puffer cylinder, a hollow conductor, an insulating rod connected to the puffer cylinder, and a fixed piston fitted inside the puffer cylinder. An insulating gas is ejected to a space between the puffer cylinder and the fixed piston by driving the insulating rod and is sprayed to an arc generated upon interruption of a current. The hollow conductor is in a cylindrical shape having a cross section parallel to the axis thereof. The cross section is smaller in diameter on the downstream side of a flow of insulating gas. The hollow conductor has a closed end on the downstream side of the flow of insulating gas and has a cylindrical barrel portion provided with a plurality of opening. With this configuration, this circuit-breaker ensures an operation of adjusting the flow of a heat gas, cooling of the heat gas and insulating performance for the fixed conductor to which the heat gas is sprayed.

摘要： A power receiving and transforming system comprising a gas insulated switchgear, with transformers being disposed adjacent the gas insulated switchgear and metal enclosed switchgear sections disposed on opposite sides of the transformers with respect to the gas insulated switchgear. The metal enclosed switchgear sections have metal enclosed switchgear units juxtaposed in a direction in which the gas insulated switchgear and the transformers are juxtaposed. The metal enclosed sections are located opposite to each other in a direction perpendicular to the direction of the juxtaposition. Therefore, the metal enclosed switchgear sections can be arranged so as to have a width equal to a width of the gas insulated switchgear and the width will not change even if the number of feeders in the metal enclosed switchgear sections is increased thereby enabling the entire power receiving and transforming system to be regularly installed at a site.
