摘要： A contact blade for a circuit breaker configured such that the current path in the blade produces a magnetic field which affects an arc present at the contact of the blade. The configuration of the blade produces a substantially U-shaped current loop in the blade, wherein one leg of the current loop has its main component substantially parallel to, but in the direction opposite to, the main component of the current in the second leg of the loop. When an arc is formed at the contact, the current from the second leg flows through the contact and into an arc, while the current in the first leg of the loop produces a magnetic field which acts upon the arc and forces the arc off of and away from the contact.

摘要： A portable breakload tool which permits opening of electric devices under load so that the opening is made without apparent external arc. The tool includes an arch quenching chamber in which two fixed contacts and a rotatable contact are positioned. The movable contact is operated externally to cut current between the contacts. The electric arc is confined within the chamber and is quenched by the sulfur hexafluoride gas which fills the chamber.

摘要： An electric high-voltage circuit breaker is provided with two coaxially arranged contact members, which are movable relative to each other, with one rated-current contact (5, 7) and one burning contact (5, 7) each. The rated-current contact (7) and burning contact (7) of one movable one of the two contact members are frictionally joined to each other via a support part. The end, turned away from a stationary one of the two contact members, of the rated-current contact of the movable contact member is in contact, in a sliding manner, with a current supply of this contact member. This breaker is to be further developed in such a manner that the use of an additional sliding contact between the burning contact and the current supply can be omitted even when switching extremely large currents. This is achieved by the fact that the rated-current contact of the movable contact member is formed by contact fingers which are elastically supported on the support part (18) and that the support part is constructed to be electrically conductive and has a contact surface which acts in conjunction with the contact surfaces of the contact fingers after separation of the rated-current contacts. Such a breaker is preferably used as a generator switch.
摘要翻译：电气高压断路器具有两个同轴布置的接触构件，它们可相对于彼此移动，每个具有一个额定电流接触件（5,7）和一个燃烧接触件（5,7）。两个接触构件中的一个可移动接触构件的额定电流触点（7）和燃烧触头（7）经由支撑部分彼此摩擦接合。与可动接触构件的额定电流接触件的两个接触构件中的静止的一个相反的端部以滑动的方式与该接触构件的电流供应接触。该断路器将进一步开发，即使在切换非常大的电流时也可以省略在燃烧接触和电流源之间的附加滑动接触的使用。这是通过以下事实实现的：可动接触构件的额定电流接触由弹性地支撑在支撑部分（18）上的接触指形成，并且支撑部分被构造为导电并且具有接触表面在额定电流触点分离后，与接触指的接触表面一起作用。这种断路器优选用作发电机开关。

摘要： A switching apparatus for disconnecting and connecting power between a power source and a load employs a vacuum switch, a knife blade or air switch coupled electrically in series with the vacuum switch and a positive interlock mechanism. In the disconnect mode, at first the bias on a springloaded movable contact of the vacuum switch is relieved; then the vacuum lock that maintains the movable contact engaged with the fixed contact in the vacuum switch is overcome to cause complete separation of the contacts, thereby breaking the connection to the power source; and finally the knife blade is moved to open the air switch and to a position providing a visual indication that the power to the load has been interrupted. A continuous force is applied to the interlock mechanism, but the disconnect process occurs sequentially in three steps. During the connect mode, the three step process is reversed.

摘要： A disconnect switch for high-voltage installations is disclosed. The switch includes a pair of hollow contacts, one of which is movable, disposed in a grounded metallic housing filled with compressed gas. A spring-loaded contact-breaking pin is provided in one of the hollow contacts. The pin is provided at its free end with a recess which is engaged in the "on" position of the switch by a ratchet device pivotally disposed in the other contact. During movement of the movable contact toward the "off" position of the switch, the contact-breaking pin remains in contact with the ratchet device. The mechanically controlled ratchet device releases the contact-breaking pin at a given position of the movable contact. The contact-breaking pin is then returned by its spring into its hollow contact with a velocity greater than that of the movable contact. Any arc which may be generated between the ratchet device and the contact-breaking pin is thereby quickly quenched even though the disconnect switch is driven at a slow speed.
摘要翻译：公开了用于高压安装的断开开关。开关包括一对中空触点，其中一个可移动，设置在充满压缩气体的接地金属外壳中。弹簧加载的接触破坏销设置在其中一个中空触点中。销在其自由端处设置有凹部，该凹部通过枢转地设置在另一个触点中的棘轮装置接合在开关的“开”位置。在可动触头向开关的“断开”位置移动期间，触点断开销与棘轮装置保持接触。机械控制的棘轮装置在可动触点的给定位置释放触点断开销。接触破坏销然后由其弹簧以大于可动触点的速度返回到其中空触点。因此，即使以慢速驱动断开开关，也可以在棘轮装置和接触断开销之间产生的任何电弧迅速熄火。

摘要： An easily visible condition indicating device to signify a lack of pressure within the envelope of an electrical interrupter of the type utilizing a pressurized-gas environment. The system includes a rotatable drum contained within a housing having an aperture through which the drum is viewed. When pressure within the interrupter drops a spring-biased bellows collapses, causing the withdrawal of stops which hold the drum in place against spring tension. This allows a biasing spring to rotate the drum so that a different portion thereof, such as a different colored segment, is viewed through the housing aperture in order to provide a visual indication of a low-pressure condition.

摘要： A puffer-type gas-blast circuit-breaker comprises an interrupting unit mounted in a housing filled with an insulating gas of high dielectric strength such as sulfur hexafluoride. The interrupting unit includes a main circuit having a pair of stationary and movable main contacts, and an arcing circuit having a pair of stationary and movable arcing contacts. An operating mechanism comprises a control rod coupled to the movable contacts so as to open the main contacts before the separation of the arcing contacts. A pair of input and output terminals extend out of the housing, and a shunt conductor is arranged in the arcing circuit between operating rod and the lower terminal. The longitudinally extending main and arcing circuits are connected in parallel to the terminals and form two independent current paths which are cross-wise spaced inside the housing. A partition wall divides the inner space of the housing into two superposed compartments, one of them including the main contacts, and the other the arcing zone.

摘要： A manual operator for a series-connected circuit interrupter and disconnect combination mounted within a switch gearing closure, which includes an external operating handle affixed to a common operating shaft for the interrupter and the disconnect, which is rotatable about its axis between a closed position and an open position. A quick make, quick break, interrupter operating mechanism includes a manual operating shaft which is rotatable about its axis between a closed position and an open position. An operating rod has one end pivotally connected to a lever affixed to the common shaft and an opposite end pivotally connected to a lever affixed to the interrupter operator shaft, so that when the common shaft is rotated between its closed and open positions, the interrupter operating shaft is correspondingly rotated between its closed and open positions. The operating rod is held in a toggled position at both its closed and open positions by a spring connected between the rod and the switchgear enclosure. A disconnect operating shaft which is rotatable about its axis between a closed position and an open position, is connected by a "lost motion" linkage to be operated by the interrupter operating shaft, wherein, when the interrupter operating shaft is rotated from its open position, the disconnect shaft is rotated from its open position only after the interrupter has opened, and when the interrupter operating shaft is rotated from its closed position, the disconnect will close before the interrupter closes.
