摘要： Contact pad designed to be fixed on a movable contact of a low-voltage circuit breaker designed to withstand peak short-circuit currents comprised between 200 and 600 amperes per square millimetre of pad. The pad is made of a silver- or copper-based conducting material alloy, a fraction of refractory particles such as tungsten carbide, tungsten or titanium nitride and a fraction of carbon fibres. The weight percentage of carbon fibres in the pad is strictly less than 2% of the total weight of the pad.

摘要： Disclosed is a hydraulic operating apparatus for switch with which it is possible to constantly obtain a stable interrupting performance at the time of high-speed successive operations. Closing and interrupting pressure accumulators comprise closing and interrupting pressure accumulation pistons, and closing and interrupting pressure accumulation springs for biasing the closing and interrupting pressure accumulation pistons in pressure accumulation directions, respectively. The closing and interrupting pressure accumulation springs exert, on the closing and interrupting pressure accumulation pistons, forces corresponding to received pressures acting on the closing and interrupting pressure accumulation pistons from closing and interrupting pressure accumulation chambers in a steady state. The closing pressure accumulator and the interrupting pressure accumulator are independently constituted for closing and for interrupting, respectively.

摘要： An interrupt assembly for a primary circuit breaker of a distribution transformer includes an elongated housing that is divided into separate chambers for holding insulating fluid that extinguish an arc generated when a high-voltage electrical path between two breaker contacts is broken. The elongated housing includes openings that allow for the rapid exit of the expanding gases generated as a result of the arc. Consequently, the separately held insulating fluid in each chamber presents a strong dielectric property to the arc, causing it to extinguish rapidly.
摘要翻译：用于分配变压器的主断路器的中断组件包括细长的壳体，该壳体被分成用于保持绝缘流体的分离的室，当两个断路器触点之间的高压电路断开时，消除电弧产生的电弧。细长的壳体包括允许由于电弧而产生的膨胀气体的快速排出的开口。因此，每个室中单独保持的绝缘流体对于电弧具有很强的介电性能，使其迅速熄灭。

摘要： An oil-type circuit-breaker has an improved grid structure for effecting quick extinction of the arc, which is established and lengthened within the grid structure by the separation of the rod-shaped movable contact downwardly away from the stationary-contact structure. The grid structure is constructed by providing a plurality of suitably-configured plate elements, constituting vent passages and oil pockets, within an outer cylindrical shell member. The stationary contact assembly is so arranged as to have a lengthened finger, which serves as an arcing horn, disposed adjacent the side lateral vent openings. The vent openings are formed by passages provided in the individual suitably-configured plate elements; and a splitter plate is interposed between the lateral vent passages and close to the path of movement of the movable contact rod. Additional lower-disposed oil pockets and a lower plug member having an entrance opening, assist in guiding the upward movement of the movable contact rod, and additionally provide considerable turbulence within the oil-grid structure during the opening operation.
摘要翻译：油型断路器具有改进的栅格结构，用于通过将杆状可动触头向下远离固定接触结构分离来实现电弧的快速消光，其在栅格结构内被建立和延长。格栅结构通过在外圆筒形壳体内设置多个适当构造的板元件构成排气通道和油袋来构造。固定接触组件布置成具有设置成邻近侧面通气口的延长的手指，其用作电弧喇叭。通风口由设置在各个适当构成的板元件中的通道形成; 并且分离板插入在侧向通气通道之间并且靠近可动接触杆的运动路径。附加的下部布置的油穴和具有入口的下部塞构件有助于引导可动接触杆的向上运动，并且在打开操作期间另外在油网结构内提供相当大的湍流。
