摘要:
The present invention relates to a main circuit part of a vacuum circuit breaker, and more particularly, to a main circuit part of a vacuum circuit breaker with a temperature sensor. The main circuit part of a vacuum circuit breaker with a self-powered temperature sensor assembly includes: a self-powered temperature sensor module; and a support bracket enclosing and supporting the self-powered temperature sensor module.

Ein Schaltmagnet (10) mit einer Erregerspule, die eine auf einem Spulenkörper (4) angeordnete Wicklung (3), einen in einer zentralen Durchgangsöffnung (4a) des Spulenkörpers angeordneten Polkern (2) sowie einen in der Durchgangsöffnung (4a) des Spulenkörpers (4) axial verlagerbaren Magnetkolben (5) umfasst, wobei optional eine vom Magnetkolben (5) bewegbare Achse (7) vorgesehen ist, weist zumindest einen in den Schaltmagneten (10) integrierten Kalbenpositionsdetektor (20) auf. Dieser Kolbenpositionsdetektor (20) umfasst bevorzugt zumindest zwei Kontakte und ein Schaltelement, wobei das Schaltelement direkt oder mittelbar durch den Magnetkolben (5) betätigbar ist und bei Betätigung Kontakte öffnet und/oder schließt.
摘要:
Forecasting the end of the service life of a relay more accurately due to the effects of the load conditions and the environmental conditions can occur through diagnosing the end of service life of the relay based on the time, until the point in time that the actual opening or closing of the relay is detected, from the point in time of the application of the power to the relay or the point in time of the end of application of power to the relay coil by the controlling portion. Forecasting the end of the service life of the relay based on time, increases accuracy because time is a value that is not affected by the external environment. Additionally, because the end of the service life is forecasted based on the actual opening/closing of the relay, not only is it possible to detect immediately a fault in the relay, but it is also possible to eliminate the effects due to individual differences.
