摘要:
The present invention relates to a method for reclaiming a substance from an insulation medium (22) of an electrical apparatus (10) for the generation, transmission, distribution and/or usage of electrical energy, the insulation medium (22) comprising an organofluorine compound and a further component in gaseous phase. The method comprises the subsequent steps of: a) transferring an initial gas mixture containing the organofluorine compound and at least one further component of the insulation medium (22) out of an insulation space (16) of the electrical apparatus (10) into a substance reclaiming device (30), b) liquefying the organofluorine compound in the substance reclaiming device (30) by bl) compressing the initial gas mixture, and b2) cooling the compressed initial gas mixture down to a temperature where the organofluorine compound liquefies, and c) separating the liquefied organofluorine compound from the remaining gas comprising the at least one remaining component of the initial gas mixture.

The invention relates to a leadthrough arrangement (1) comprising a separating switch component which is connected to an electrically insulating cover (10) in the manner of an open-air leadthrough. A tubular shaped electrode (9) is arranged in the flange area of the electrically insulating cover (10) and the separating switch component, said electrode projecting over the flange (4). A common gas chamber is formed by the electrically insulating cover (10) and the housing (2) of the separating switch component.

An ultrafast electrical (e.g., transfer, disconnect, etc.) switch that is simple, compact, does not require high energy to operate, ultralow loss, clean, and capable of being automatically reset. The invention includes a fast electromechanical switch having a drive mechanism integrated into the switching chamber. The integration of the drive mechanism into the switching chamber provides faster contact travel and therefore a faster switching operation. Additionally, the switching chamber is a self-contained environment that may consist of a high-pressure gas or a vacuum. The invention further includes an ultrafast disconnect switch. The invention generally is an integrated piezoelectric-actuator-based mechanical switching mechanism. The mechanism has a central piezoelectric actuator that extends to pull contacts inwards in order to obtain two disconnects within a millisecond or less. Surrounding the piezoelectric actuator is a polymer insulating shell and beyond the shell is the metallic conductor.

Die Erfindung betrifft einen dreiphasig betriebenen Trenn- und/oder Erdungsschalter einer dreiphasigen gasisolierten metallgekapselten Mittelspannungs- oder Hochspannungsschaltanlage, dessen drei Schalterpole (1.1, 1.2) neben- oder übereinander in einer Ebene angeordnet und horizontal ausgerichtet sind, wobei die Schalterpole (1.1, 1.2) über eine gemeinsame Antriebsvorrichtung betätigbar sind. Ein mittleres bewegliches Kontaktstück (3) des zwischen den äußeren Schalterpolen (1.1) liegenden mittleren Schalterpols (1.2) ist mit einem Antriebsausgang der Antriebsvorrichtung über eine Getriebeanordnung (5, 6, 12, 13) mechanisch verbunden und darüber in Bewegung versetzbar. Jeweils ein äußeres bewegliches Kontaktstück (4) der beiden äußeren Schalterpole (1.1) ist mittels einer Wellenanordnung mechanisch an die Getriebeanordnung angebunden und darüber in Bewegung versetzbar, so dass die Einspeisung der vom Antriebsausgang bereitgestellten Antriebsenergie auf das mittlere bewegliche Kontaktstück (3) symmetrisch zu den äußeren beweglichen Kontaktstücken (4) erfolgt.

The present invention relates to a clutch mechanism for an energy storage device, comprising a load gear (25), a drive gear (22), a one-way bearing (23), a bushing (28), and a gear shaft (24) comprising a gear portion (241) and a clutch portion (242). The gear shaft (24) comprises multiple cylinders (27), and a push rod (21), a rotary sleeve (31) and an elastic element (20) located in a cavity of the gear shaft (24). The push rod comprises a push rod slide hole (211) and a push rod connecting hole (212), for connecting to the gear shaft (24) and the rotary sleeve (31), respectively. A press block (26) is fixed to the drive gear (22), the press block (26) being capable of pushing the push rod (21) to slide axially, so as to unlock or lock the bushing (28) and the gear shaft. The present invention also relates to a gas insulated circuit breaker using such a clutch mechanism. The clutch mechanism and gas insulated circuit breaker thereof according to the present invention enable simple and reliable mechanical separation of a motive power device and an energy storage device once energy storage is complete at a relatively low cost.
