Patent number: 6960844Abstract: An electric switching device for alternating current comprises two branches (2, 3) connected in parallel in a current path and having each at least two contact members (4–7) connected in series. A semiconductor device (8) is adapted to interconnect the midpoints between the two contact members of each branch. When opening the current path a first contact member (5) of one, first branch located before said midpoint as seen in the current direction existing is controlled to open and a second contact member (6) of the second branch located after the midpoint as seen in the current direction is controlled to open for transferring the current to a temporary current path through the semiconductor device. The current path through the switching device is then broken when the semiconductor device is in a blocking state by opening a contact member (4, 7) of the switching device arranged in the temporary current path.Type: GrantFiled: November 20, 2000Date of Patent: November 1, 2005Assignee: ABB Technology AGInventors: Falah Al-Hosini, Jan Smede, Jan-Anders Nygren Nolemo, Magnus Backman, Philip Kjaer, Lennart Balgård, Per Larsson, Ove Albertsson, Lars Jonsson, Jan Johansson

Patent number: 5525976Abstract: For temperature measurement at a number of measuring points on, for example, current-carrying bars (2) in a high-voltage switchgear, a data transmitter (1) is used which is arranged near each measuring point and at the same potential as such point. The transmitter is controlled by a temperature sensor (8) and comprises components (3, 4) for capturing drive energy from the electric or the magnetic field around the bar. The temperature sensor (8) may consist of a quartz crystal, the resonance frequency of which has a specified temperature dependence. Measured data is transmitted by means of light (e.g. infrared) in the air to a data receiver (10) at ground potential. The data receiver (10) is able to receive measured data from a plurality of data transmitters.Type: GrantFiled: July 20, 1993Date of Patent: June 11, 1996Assignee: Asea Brown Boveri ABInventor: Lennart Balgard
