摘要： Featured is a particulate and pressure redirection barrier for an electrical breaker as well as a breaker embodying such a barrier. Such a barrier includes first through fifth segments, where the first segment includes a first and second side section and a bottom section that are coupled to each other so as to form a generally U shaped structure. The second segment is coupled to the first side section so it extends outwardly at an angle from the first side section. The third segment is coupled to the second side section so as to extend outwardly and at an angle from the second side section. The fourth segment is coupled to the second segment so as to extend outwardly from and at an angle with respect to the second segment. The fifth segment is coupled to the third segment so as to extend outwardly from and at an angle with respect to the third segment. Such a configuration of the fourth and fifth segments is such that gas flowing along a surface of the second or third segments is redirected at an angle with respect to that surface.

摘要： A gas-insulated high-voltage switch for the interruption of large currents includes a housing, a contact arrangement which is arranged in the housing and has two switching pieces which can be moved relative to one another along an axis. Each switching piece has a rated current contact and an arcing contact. The switch includes a drive which acts on a first of the two switching pieces. The switch includes a device configured to detect and indicate the contact wear of the two arcing contacts caused by the action of the arc. The device has an indicator arranged outside the housing. In the switch, the remaining life which is determined by the contact wear of the arcing contacts is detected and indicated by a simple mechanical mechanism. The device has a transmission mechanism which is fed through the housing in a gas-tight manner and a drive member coupled to the operating element.

摘要： A limited flash-over electric power switch uses a dielectric gas regulator and a flash-over arrestor to greatly diminish the occurrences of high voltage flash-over during operation of a circuit interrupter. The dielectric gas regulator prevents the flow of the dielectric gas into the arc gap during an initial portion of the opening stroke of the interrupter contacts. Once the arc gap is sufficiently wide to greatly diminish the likelihood of a high voltage flash-over, the dielectric gas regulator allows the dielectric gas to flow into the arc gap to extinguish the arc. The flash-over arrestor snubs out incipient flash-over that may occur as the arc attempts to reform across the arc gap. The flash-over arrestor may be a conductive ring located on the interior surface of the nozzle in the region of the orifice.
摘要翻译：有限的闪光电力开关使用电介质气体调节器和闪光保护器来大大减少在电路断续器的操作期间高压闪络的发生。电介质气体调节器在断路器触点的打开行程的初始部分期间防止电介质气体流入电弧间隙。一旦电弧间隙足够宽以大大降低高电压闪络的可能性，则电介质气体调节器允许电介质气体流入电弧间隙以熄灭电弧。闪电避雷器会缓慢发生，因为电弧试图在电弧间隙内进行改造，这可能会发生。闪光避雷器可以是位于喷嘴区域内的喷嘴内表面上的导电环。

摘要： A puffer-type gas blast circuit breaker is capable of restraining reduction in creepage insulation resistance of an insulating support and an insulating rod due to insulating gas of high temperature. An electrode section is mounted on a stationary member supported on an insulating support, and a stationary side arc contact and moving side arc contact are disposed facing each other to contact and separate; a hollow piston rod and an insulating rod are connected to the moving side arc contact, and inserted in a stationary member body portion; and a gas flow blocking member is mounted on an end of the piston rod to prevent an insulating gas heated and coming to the stationary side from getting into the insulating rod side. The stationary member body portion is formed cylindrical so that a gap between the body portion of the stationary member and the gas flow blocking member is minimized.
