20110084048 | CIRCUIT BREAKER WITH PARALLEL RATED CURRENT PATHS - A circuit breaker is provided which can be filled with a quenching gas and which has two contact arrangements, which can be moved relative to one another and along a longitudinal axis of the circuit breaker. The contact arrangements form a arcing contact system and a rated current contact system connected electrically in parallel with it. One of the contact arrangements includes inner rated current contacts and outer rated current contacts of the rated current contact system, where the inner rated current contacts overhang the outer rated current contacts in the direction of the longitudinal axis, and the outer rated current contacts coaxially surround the inner rated current contacts. The circuit breaker has a high current carrying capability as well as a reliable switching-on and -off behavior, such as during and after the occurrence of a short-circuit current in the circuit breaker. | 04-14-2011 |
20110278263 | GAS-INSULATED HIGH-VOLTAGE SWITCH - A high-voltage switch includes a contact arrangement having two arcing contacts, one of which is supported displaceably against the action of a pretensioned spring. When the contact arrangement is closed, the free ends of the two arcing contacts are supported on one another. When the contact arrangement is opened, the two arcing contacts separate and during this process an arcing zone, accommodating compressed arc gas, is produced which is limited axially by free ends of the two arcing contacts and radially by an insulating nozzle toward the outside. To prevent the displaceably supported arcing contact from returning against the action of the pretensioned spring when a large short-circuit current is interrupted, the switch includes a piston/cylinder system functioning as a restoring device, which communicates with the arcing zone and which, with increasing pressure of the compressed arc gas produced in the arcing zone, generates a restoring force supporting the repelling force of the pretensioned spring. | 11-17-2011 |
20130213936 | GAS-INSULATED HIGH-VOLTAGE SWITCH FOR INTERRUPTION OF LARGE CURRENTS - A gas-insulated high-voltage switch for the interruption of large currents includes a housing, a contact arrangement which is arranged in the housing and has two switching pieces which can be moved relative to one another along an axis. Each switching piece has a rated current contact and an arcing contact. The switch includes a drive which acts on a first of the two switching pieces. The switch includes a device configured to detect and indicate the contact wear of the two arcing contacts caused by the action of the arc. The device has an indicator arranged outside the housing. In the switch, the remaining life which is determined by the contact wear of the arcing contacts is detected and indicated by a simple mechanical mechanism. The device has a transmission mechanism which is fed through the housing in a gas-tight manner and a drive member coupled to the operating element. | 08-22-2013 |
