    摘要: Voltmeter for medium/high-voltage devices, which has a surface-wave device (21) as the voltmeter element proper. This surface-wave device is incorporated into an impedance voltage divider (5, 6), of a type known in principle, in such a way that both electrical high-voltage insulation is ensured and power supply problems of the voltmeter element which is at high potential are ruled out.

    摘要: In breaker devices an early short-circuit recognition is required and also a tripping of the contacts. The recognition of a short-circuit occurs so early that with consideration of the response time of the measuring probes and the unlocking mechanism by a suitable analysis algorithm the release of the movable contact occurs before or at least at the time that the current-breaking forces correspond to the contact force. The contact force is hence compensated for and a rapid opening of the contacts can be achieved.

    摘要: A switching device includes a working circuit, to which an operating voltage can be or is applied to which has at least one electronic switching element. This switching element includes at least one control terminal for applying a switching signal and is switched off or switched on depending on the switching signal. At least one electronic protection element is for protecting the switching element in its switched state from excessive Joule losses in the event of danger, especially in the event of an overload or a short circuit. The protection element bears the predominant part of the operating voltage that is released at the working circuit. The switching device includes a switching-off device, which, in the event of danger, automatically switches the switching element to the switched off state, using the energy contained in the operating current or the operating voltage passing through the working circuit or the voltage that is released at the working circuit or at the protection element exceeds a predetermined upper limit value.

    摘要: A drive solenoid, a yoke, an armature and at least one contact are mounted in a housing of an electromagnetic switching device. The drive solenoid, yoke and armature are inductively intercoupled, in such a way that when an inrush current is applied to the drive solenoid, the armature can be displaced into a pickup position, thus directly or indirectly actuating the contact. The yoke and/or armature contain(s) pulverulent magnetic material.

    摘要: A method with corresponding circuit arrangement is disclosed, whereby for evaluation of a measured signal arising as an analogue value with a potential greater than zero potential in a measuring device requiring a supply current, the measured information therefrom is transmitted as a digital signal to an analytical unit lying at earth potential after an A/D conversion. The generated digital signal thus provides the clock signal for a modulation of the supply current and thus also carries out the function of the carrier for the information content of the measured signal. Curved characteristic lines for compression/decompression of the signals are used. Suitable devices for temperature compensation may be similarly provided.

    摘要: In installations including fixed and mobile structural elements and a rotary current motor as a drive, the rotary current motor can be used for the wireless transmission of both energy and/or data. The transmission from the fixed structural elements to the mobile structural elements of the rotary current motor is especially inductive. In the corresponding device including a rotary current motor including a stator and a secondary element, the secondary element is not embodied as a solid conductor with or without a laminated core, according to prior art, but rather as a laminated core including integrated windings which is the same as, or similar to, the stator.
