摘要： A circuit closer includes: a vacuum interrupter in which one of a pair of electrodes oppositely disposed in a vacuum vessel, wherein a gap d between the pair of electrodes always satisfies d>0, and a gap d1 between the pair of electrodes in a state in which closing of a circuit is completed, is shorter than a distance d2 at which insulation between the pair of electrodes is broken down by a charge voltage V of the circuit that is to be closed, and is longer than a distance d3 at which the pair of electrodes are bridged by a deposition of an electrode metal after a closing operation, the deposition resulting from evaporation caused by heat of an arc generated when the circuit is closed.

摘要： There is disclosed a method of diffusing gaseous medium such as tritium into a vessel such as a tube of an overvoltage protector. According to the method, a vessel such as a tube including a wall portion made of a material permitting diffusion of gas therethrough is provided. This vessel is heated to a predetermined elevated temperature and sealed while the vessel is at the elevated temperature. The vessel is thereupon evacuated and exposed to an atmosphere of gas to be diffused into the vessel while maintaining this atmosphere for a predetermined period of time at an elevated temperature less than the sealing temperature and at a pressure higher than the pressure within the sealed and evacuated vessel, thereby causing diffusion of gas into the vessel for filling the same with the gas. There is also disclosed a device for carrying out the hereinbefore described method.

摘要： An electrode configuration for an electrical component, in particular a surge protector, includes two electrodes extending in a plate-shaped manner parallel to a radial plane relative to a connection axis of the electrodes, defining an axial direction. At least one electrode has a connection region lying in the radial plane and at least two, three or four ribbon-shaped strips each extending away from the connection region and at least partially in circumferential direction relative to the axial direction. A fault arc, occurring during a lightning strike, can be conducted outwards away from the electrical component and forced into rotation around the electrical component in an effective manner due to the ribbon-shaped strips at the outer edge of the connection region and at least two ribbon-shaped strips overlapping each other at a spacing with respect to their delimiting surfaces lying perpendicular to the axial direction.

摘要： A triggered vacuum gap (TVG) device that has application as a closing switch for synchronized closing in distribution and transmission power systems. The TVG device controllably sustains a current arc in the device through initial current zeros created by power system transients and, thereby, prevents premature interruption of the closing operation. The TVG device includes main electrodes defining a vacuum gap therebetween and a triggering electrode providing a triggering gap between one main electrode and the triggering electrode. The TVG device also includes a triggering circuit having a high voltage impulse source that supplies a fast rising impulse voltage to the one main electrode and the triggering electrode for creation of a plasma to provide an initial breakdown of the triggering gap and a low voltage unidirectional current source that supplies current to the one main electrode and the triggering electrode once the first triggering gap breakdown has occurred.
