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.
摘要翻译：一种开关装置，包括电绝缘框架，其具有容纳在其前部的操作机构，并且在其后部容纳有主电路。绝缘框架通过相对的侧绝缘壁和基本上呈U形横截面布置的后绝缘壁限定了在三侧被包围的空间。绝缘框架还支撑在该空间内的开关部分，并且支撑从延伸穿过后绝缘壁的开关部分的端子导体引线朝向开关装置的后部突出。开关装置还包括电绝缘盖，其至少在操作机构的后端，顶端和相对侧端处覆盖绝缘框架的前侧。此外，开关装置可以包括设置在开关装置的前部的面板和设置在面板和绝缘框架之间的操作机构。因此，可以使部件之间的绝缘距离小，并且不需要金属外壳，从而允许开关柜体积小，结构简单。

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： 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.
