本発明は、電力用遮断器に係り、特に、駆動力低減をは
かるのに好適な構造の三相一括操作型遮断器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power circuit breaker, and particularly to a three-phase collectively operated circuit breaker having a structure suitable for reducing driving force.
ＳＦ６ガスを消弧媒体としたバッファ型ガス遮断器は、
構造簡単で遮断性能が優れているため。The buffer type gas circuit breaker uses SF6 gas as the arc extinguishing medium.
Due to its simple structure and excellent breaking performance.
高電圧・大容量遮断器として広く使用されている。Widely used as a high voltage/large capacity circuit breaker.

循環を生むことになる。Recently, three-phase batch-operated circuit breakers, which drive three-phase circuit breakers at the same time with one operating device, have come into widespread use due to their low cost. During operation, a relatively large operating force is required due to the interruption principle of compressing SF6 gas by itself as soon as the contact is opened, and spraying the gas onto the arc to achieve current interruption. In a three-phase collectively operated circuit breaker, three phases are driven by one operating device, so a very large operating force is required. It is necessary to ensure sufficient mechanical strength of the operating force transmitting section against the operating force, which results in an increase in the weight of the operating force transmitting section, creating a vicious cycle that further increases the operating force.

している。FIG. 3 shows an example of a conventionally used three-phase collectively operated circuit breaker, which is disclosed in Japanese Patent Laid-Open No. 102423/1983. This is a view of the circuit breaker from above, showing the closed state.

分３は、絶縁物製ロット４を介して。A, B, C three-phase containers IA, IB, (2) each contain a buffer-type shutoff section 2. The movable part 3 of the shutoff section is connected via an insulating rod 4.

たエネルギによる構造となっている。The hinges 8 are connected to each other by a rod 9 connecting the phases, and one end thereof is connected to an operating piston 11 via a hinge 10, and the other end is connected to a dashpot for shock absorption. In this example, the closing operation is performed using energy stored in springs 13a and 13b arranged between the phases.

、寿命の点から改善が望まれていた。As the rating of the circuit breaker increases, the driving force required for the circuit breaker operation increases, so the hinge 10.8, rod 9
etc., require strength to withstand that force, which increases their weight. In particular, in a structure in which the operation piston 11 is located at the end, there is a case where excessive impact stress is generated due to the bumping phenomenon due to play at the joint of the hinge lever at the start of the shutoff operation, so it is necessary to ensure sufficient strength. These components account for a considerable proportion of the total weight of the movable parts, and improvements have been desired in terms of reliability and service life.
本発明の目的は、可動部の重量を軽減して、小さな操作
力で良好な遮断性能を達成する二相一括操作型遮断器を
提供することにある。An object of the present invention is to provide a two-phase collectively operated circuit breaker that reduces the weight of movable parts and achieves good interrupting performance with a small operating force.
上記目的は、遮断動作に必要な駆動力を得るための操作
ピストンを、相間にそれぞれ一つずつ配置することによ
り達成される。The above object is achieved by arranging one operating piston between each phase to obtain the driving force necessary for the shutoff operation.
相間にそれぞれ配置された操作ピストンは、同一の制御
弁で同時に駆動されるので、玉突現象による過大な応力
の発生が抑制され、操作力伝達部の軽量化が図れる。そ
れによって、駆動力の低減が可能となる。Since the operating pistons disposed between the phases are simultaneously driven by the same control valve, generation of excessive stress due to the bump phenomenon is suppressed, and the weight of the operating force transmission section can be reduced. This makes it possible to reduce the driving force.
