摘要： A method for testing high-voltage alternating-current power switches in a synthetic test circuit has the step of connecting a high-voltage oscillating circuit in parallel to a test switch Bt in a time interval before the current zero of an interruptible high current, which is determined by a half-cycle duration (Th/2) of the oscillating current (ih) less the duration of equivalence (Δtse) of the sole flow of the oscillating current as sequential current in the test switch with a stress exerted upon the switch by the homogeneous current in a direct test circuit. The sequential-current flow duration of the equivalence results, at least approximately, from the comparison of the values of common physical stress parameters acting in the test switch during the test, on the one hand, in the synthetic test circuit and, on the other hand, in the direct test circuit.

摘要： A high-voltage oscillating circuit (I) is connected in parallel with an auxiliary circuit-breaker (Ba) by firing a switching spark gap (SGhv) and the oscillating current (ihv) is superimposed on the high-current (ihc) with opposite polarity just before the high-current zero crossing. The spark gap (SGhc) is fired at the artificial current zero, causing: short-circuiting of the high-current source (a), series connection of the high-voltage oscillating circuit with the test circuit-breaker (Bt), oscillating current from the auxiliary circuit-breaker is transferred with constant parameters to the test circuit-breaker there—in following the eliminated high current. Transient high voltage follows the zero crossing of the synthetic current continuously.

摘要： In a dual-gas-blast puffer-type circuit-breaker a fixed insulating nozzle body (4) is integrated into a fixed insulating piston (10), forming thus a structural component. Said structural component is mounted on a fixed cylinder (11). Up to the large inner diameter of the latter the nozzle contour may expand freely, allowing thus a more effective removal of the arc plasma from the nozzle region.This feature facilitates interrupting the arc by increasing the cooling rate of the gas flow past the arc.The movable arc contact piece (17) is provided with a conical transition member between the nozzle shaped inlet side and the cylindrical base (16). That conical transition member is working like a movable piston exposed to the downstream gas flow pressure. Thus at least partly a selfcompensation of the increased gas pressure on the compression cylinder takes place in cases where large short circuit-currents are to be interrupted. This feature represents the precondition for a simple and thus reliable drive.
