摘要: A gas-insulated switchgear provided with a resin mold bushing for supporting and insulating a main circuit conductor from a ground tank is miniaturized. A container portion 3a is formed by opening an end inside of the tank of a resin mold bushing 3 for supporting and insulating an internal conductor 7 from a ground tank 1 where a breaker 2 and a disconnector are accommodated. A blade-supporting conductor 5 of the disconnector for joining the internal conductor 7 and the disconnector is installed in the container portion.

摘要: A switchgear comprising an electrically insulating frame having an operating mechanism accommodated at its front portion and having a main circuit accommodated at its rear portion. The insulating frame defines a space surrounded at three sides by opposing side insulating walls and a rear insulating wall arranged substantially in a U-shaped cross section. The insulating frame also supports a switch portion within the space and supports a terminal conductor leads from the switch portion extending through the rear insulating wall to project toward the rear of the switchgear. The switchgear also comprises an electrically insulating cover covering at a front side of the insulating frame at least the rear end, the top end and the opposing side ends of the operating mechanism. Also, the switchgear may comprises a face plate disposed to a front portion of the switchgear and an operating mechanism disposed between the face plate and the insulating frame. Therefore, the insulating distance between the components can be made small and no metal casing is necessary, allowing the switchgear to be small-sized and simple in structure.

摘要: An operation mechanism of a circuit breaker which is highly reliable and inexpensive and in which an intermittent meshing of toothed wheels and resultant noise do not occur. The operation mechanism includes a gear wheel for driving a cam shaft to store mechanical energy into a breaking spring, a pinion meshed with the gear wheel and a clutch driving element provided on the same axis as the pinion and constituting a clutch with the pinion. An operational driving electric motor is provided to drive the clutch driving element. Coupling between the pinion and the clutch driving element is disconnected by means of a cam mechanism composed of an end cam provided on an end face of the gear wheel and the clutch driving element, in the vicinity of the stationary positions of the cam and the gear wheel in the force storing state of a closing spring.
