    摘要： A switching device (1) for an encapsulated electric power distribution switchgear comprising a switch (10), an electrically conductive housing (20) to which the switch is mounted, and which housing (20) comprises an opening (24) that leads into the housing (20). The switch comprises a first electric contact (12) connected to a first conductor (16) and a second electric contact (14) connected to a second conductor (18), the second contact being movable in relation to the first contact and in relation to the housing. The further comprises an operating shaft (30) of electrically insulating material being rotatable about its longitudinal axis Y in relation to the housing, and which is inserted into the housing via the opening (24), and an actuator member (40) located inside the housing and having a first end (42) coupled to the shaft and a second (44) end coupled to the second contact (14). The actuator member is made of an electrically insulating material. The shaft (30) extends through the opening (24) and into the housing without directly contacting the housing (20) and is supported in the housing (20) by the actuator member. The actuator member (40) is movably supported in the housing (20) at a connection area (26) that forms an interface (27) between the actuator member and the housing. The interface is located at a distance D from the longitudinal axis Y of the shaft that is longer than a distance d between the longitudinal axis Y of the shaft and a circumferential edge (23) that delimits the opening (24) in the housing, which first and second distances are measured in the same radial direction in relation to the longitudinal axis Y.

    摘要： The present invention relates to a method and a system for monitoring transformer bushings. The method comprises recording time series (401,402) comprising information from a first bushing sensor, a second bushing sensor, a third bushing sensor, and a fourth bushing sensor, wherein the first bushing sensor and the second bushing sensor are connected to a common first phase of a high voltage source, and the third bushing sensor and the fourth bushing sensor are connected to a common second phase of the high voltage source. The method further comprises generating a first time series comprising information from the first bushing sensor and the second bushing sensor during a predetermined time interval, generating a second time series, substantially simultaneously with the first time series, comprising information from the third bushing sensor and the fourth bushing sensor during the predetermined time interval, and generating a correlation model (403) for the first time series and the second time series measuring a first signal (404) corresponding to a measurement of the first time series, measuring a second signal (405) corresponding to a measurement of the second time series, determining a difference (406) between the measured first signal or the measured second signal, and an estimated first signal or an estimated second signal being estimated by means of the correlation model and the measured first or second signal, and generating a signal indicative of a bushing problem (407) if it is determined that the determined difference is larger than a predetermined threshold value.
