    摘要： The present invention relates to a puffer type circuit breaker having a high voltage and large capacity, which is provided with an insulating nozzle for blowing a arc-extinguishing gas of high pressure generated by separating a movable contactor from a fixed contactor. The fixed contactor has a larger diameter portion formed on the base portion thereof and a smaller diameter portion formed at the tip end thereof, and the insulating portion has a first throat portion adjusted by the smaller diameter portion and a second throat portion located at the downstream side of the first throat portion and adjusted by the larger diameter portion, thereby allowing the gas inlet portion to be formed by the diameter difference between the first throat portion and the smaller diameter portion which is in such manner that the second throat portion is adjusted by the larger diameter portion. By virtue of these features, when the contactors are separated from each other, even if the arc-extinguishing gas of high pressure flows into the space between the first throat portion and the second throat portion, the rapid gas flow is not generated therein. Accordingly, since the arc-extinguishing gas is prevented from lowering the gas density on the tip of the fixed contactor, it is possible to improve the breaking ability of small capacitive current.

    摘要翻译： 本发明涉及一种具有高电压和大容量的河豚式断路器，其具有用于吹送通过将活动接触器与固定接触器分离而产生的高压灭弧气体的绝缘喷嘴。 固定接触器在其基部形成较大的直径部分，在其前端形成较小直径的部分，绝缘部分具有由较小直径部分调节的第一喉部和位于下游的第二喉部 并且通过较大直径部分进行调节，从而允许气体入口部分由第一喉部和较小直径部分之间的直径差形成，其中第二喉部分和第二喉部分之间的直径差是以第二喉部被第 较大的直径部分。 由于这些特征，当接触器彼此分离时，即使高压灭弧气体流入第一喉部和第二喉部之间的空间，也不会在其中产生快速气体流动。 因此，由于防止灭弧气体降低固定接触器的尖端上的气体密度，因此可以提高小电容电流的断开能力。

    摘要： Disclosed is a switch operation monitoring apparatus for quickly and accurately detecting an abnormal operation of an actuating mechanism actuating a switch such as a power circuit breaker. A normal characteristic stroke of a moving part of the actuating mechanism is previously calculated on the basis of an interrupting current waveform, an environmental gas pressure and an actuating fluid pressure while taking into account the structure of the switch so as to use the calculated characteristic stroke as a reference stroke, and this reference stroke is compared with an actually measured characteristic stroke to decide whether the operation of the actuating mechanism actuating the switch is normal or abnormal.

    摘要： A vacuum interrupter comprises a vacuum vessel, at least a pair of electrical conductor rods extending from interior to exterior of the vacuum vessel, and at least a pair of separable composite electrodes respectively connected to the tip of the electrical conductor rods. Each of the composite electrodes has a main electrode, a parallel magnetic field generator for generating a parallel magnetic field which acts on an arc created when one main electrode is separated from the other, and a magnetic field suppressor of high electrical conductivity embedded in a central portion of the main electrode for partly cancelling the parallel magnetic field. In the vacuum interrupter, when the parallel magnetic field permeates through the magnetic field suppressor, eddy current flow is caused therein. A magnetic field due to the eddy current has a polarity opposite to that of the parallel magentic field and partly cancels the parallel magnetic field. Intensity of the parallel magnetic field then becomes smaller at the central portion than that at the other peripheral portion, and the arc tends to shift from the magnetic field suppressor to the outer peripheral portion, thereby preventing fusion damage of the magnetic field suppressor.

    摘要： An electrical power supply system includes an electrical power source system connected to a bus bar and a plurality of electric power transmission systems each connected via circuit breakers to the bus bar. The supply system has overvoltage suppression equipments each installed between the transmission system and the ground. The overvoltage suppression equipment includes a switching device and an impedance connected to the switching device. The switching device in a sound transmission system is closed when the circuit breaker operates in other faulty transmission system, thereby an overvoltage being occurred on the sound system is effectively suppressed.
