摘要:
A puffer-type gas blast circuit interrupter composed of two separable contacts defining a power current path and between which an arc is created upon separation movement, in which the movable parts of the gas compressor and/or the region of contact between the contacts of an associated nominal current path are shielded from the region in which the arc is created by a shielding arrangement composed of a stationary cylinder surrounding the nozzle associated with the gas compressor and a shield member carried by the nozzle. Additionally, to reduce the movable mass of the interrupter, at least one of the current paths is constituted by two stationary contact pieces and a movable contact member carried by, and projecting from, the cylinder of the gas compressor. Further, the mass of the moving parts of the system is reduced by providing the shield member carried by the nozzle with a cylindrical projection coaxial with, and slidable relative to, the stationary cylindrical member. Preferably, the interface between the shield member and the cylindrical member is hermetically sealed.

A pulse shaper for inductive transmitters, in particular inductive crankshaft angle transmitters on internal combustion engines is suggested, wherein a Schmitt-trigger is connected with the output of the transmitter. A peak value detector (D1,C) is connected with the output of the transmitter and means are provided which set the trigger threshold of the Schmitt-trigger in dependency on the output of the peak value detector.
摘要:
An arc blow-out switch is formed of a plurality of extinguishing units arranged in tandem, each including a movable compression cylinder and a stationary compression piston arranged in the compression cylinder. Axially aligned insulating cylinders surround each extinguishing unit. The arc blow-out switch further has a rod arrangement disposed within the insulating cylinders and connected to the compression cylinders for moving the latter as a unit to effect circuit making and circuit breaking operations.
