摘要： A power converter adapted for use in a high-voltage circuit and equipped with a plurality of arms each comprising a plurality of thyristor elements connected in series, wherein an overvoltage limiter having an overvoltage limiting element and means for short-circuiting the ends of the overvoltage limiting element in response to flow of a load current therein are connected between the anode and the cathode of each thyristor element. The short-circuiting means has a gap between the two electrodes connected respectively to the anode and the cathode of each thyristor element, and also a metal layer of a low melting point which is molten by heat generated due to the flow of a load current in the overvoltage limiting element to fill the gap.

摘要： A protected telecommunications terminal has signal conductors supported in a terminal housing, and a ground conductor positioned on the housing a small distance from the signal conductors. An electrically non-linear resistive material is located electrically between and in contact with the signal and ground conductors to provide over-voltage electrical protection to the terminal. The electrically non-linear resistive element is prepared from an electrically non-linear composition which comprises a polymeric component and a particulate filler. The composition has an initial resistivity at 25 DEG C of at least 10 ohm-cm, and is such that a standard device containing the composition has an initial breakdown voltage VSi, and after the standard device has been exposed to a standard impulse breakdown test, the device has a final breakdown voltage VSf which is from 0.7VSi to 1.3VSi. In addition, the composition in the device has a final resistivity rf at 25 DEG C of at least 10 ohm-cm.

摘要： A protector for protecting equipment, especially telephone equipment, against high voltage and/or current surges such as are caused by lightning in the vicinity of the equipment or the cables to which it is connected, comprises one or more overvoltage protectors (42, 58; 234, 236) mounted upon one face of an insulating support (18; 218). A generally planar contact member (62; 290, 312) mounted upon the support member has a ground contact member (90; 296) to make contact with a ground electrode (114; 310) in the equipment to be protected and with each overvoltage protector. A spacer (60; 320, 322) of fusible plastics material coupled thermally to the protection device melts when a sustained fault occurs. As the spacer melts, it permits an electrical connection between the contact member and the line to which the overvoltage protector is connected, effectively short-circuiting the line to ground. Overcurrent protection may be provided by means of a resistor (116) disposed in series with the line and located close to the plastics spacer so as to heat the spacer when an overcurrent occurs. In one case, the spacer comprises a film (60) interposed directly between a pair of contacts (40, 74') which serve to short-circuit the protector. In another case, the spacer comprises a limb (324) with relatively thin lateral projections (328, 338) which melt and shear. In both cases, the spacer preferably comprises high density, high molecular weight polyethylene.
摘要翻译：用于保护设备，特别是电话设备的防护装置，防止由设备附近的雷电或与其连接的电缆引起的高压和/或电流浪涌，包括一个或多个过电压保护器（42,58; 234,236），其安装在绝缘支撑件（18; 218）的一个面上。安装在支撑构件上的大致平面的接触构件（62; 290,312）具有接地接触构件（90; 296），以与要保护的设备中的接地电极（114; 310）接触，并且与每个过电压保护器。当发生持续故障时，与保护装置热耦合的可熔塑料的间隔件（60; 320,322）熔化。当间隔件熔化时，允许接触构件与过电压保护器连接的线路之间的电连接有效地将线路对地短路。过电流保护可以通过与线路串联设置的电阻器（116）提供，并且位于靠近塑料隔板的位置，以便在发生过电流时加热间隔件。在一种情况下，间隔件包括直接插入在用于使保护器短路的一对触头（40,44'）之间的膜（60）。在另一种情况下，间隔件包括具有相对薄的横向突出部（328,338）的肢体（324），该侧部突出物熔化和剪切。在两种情况下，间隔物优选包含高密度高分子量聚乙烯。

摘要： In a three-electrode surge arrester, the central electrode (3) of which has a radially projecting connecting wire (6) and is fitted with an external short-circuit device, the latter consists of a two-armed sprung bracket (20), the arms of which project axially beyond the free ends of the end electrodes and, with the interposition of an insulating foil (21), lie on the peripheral edge of the end electrodes (1, 2). The sprung bracket (24) has a roof-shaped curve (24) and an aperture in the region of said curve for securing the sprung bracket to the connecting wire (6) of the central electrode (3).

摘要： A surge-absorbing element with a function of protection from overvoltage and overcurrent in which a metal wire mechanically and elastically deformed and having high rigidity is joined with a low-melting metal to a terminal or to a lead wire of a gap-type or microgap-type surge-absorbing element. In case the surge-absorbing element generates heat due to overvoltage and overcurrent, the low-melting metal melts, the elastically deformed rigid metal wire separates from the terminal or lead wire, and the connection is broken. The rigid metal wire is connected in series with the surge-absorbing element and a device or a circuit that is to be protected.

摘要： A gas filled surge arrestor has at least one external air back-up gap comprising two spaced electrodes (7a,2 or 7a,3), one (7a) of which has at least one sharp edge or corner (9) adjacent the other electrode (2 or 3). The said one electrode (7a) is resiliently urged towards the other electrode and is coated with an insulating material (8) which prevents the two electrodes from being in direct contact and hence short circuiting. The arrangement is such that, although the sharp edge or corner (9) on said one electrode has a covering of insulating material, it is also separated from the other electrode by an air gap.
