    摘要： Partition walls of enclosed switchgear devices or enclosed lines for supporting and positioning the conductors inside the enclosure must comprise insulators for electrically separating the conducting electrical conductors led through the partition wall from the grounded enclosure. Such partition walls should be compact, especially with small radial dimensions, to allow small overall dimensions of the partition wall and consequently also of the switchgear or line, even for HV applications. This is achieved by the invention by providing an tubular insulation means 14 between a plate 12 of the partition wall 11 and a connecting means 13 for connecting the conductors 10a, 10b of two adjacent sections.

Such partition walls should be compact, especially with small radial dimensions, to allow small overall dimensions of the partition wall and consequently also of the switchgear or line, even for HV applications. This is achieved by the invention by providing an insulation means (14) of the shape of a hollow cylinder between a plate (12) of the partition wall (11) and a connecting means (13) for connecting the conductors (10a, 10b) of two adjacent sections.

    摘要： Electrical switchgear, e.g. a circuit breaker, must in general provide good dielectric strength in open position in order to avoid discharge. To improve the dielectric strength capacitors are often arranged in parallel between the contacts of the switchgear. For very high voltage applications, e.g. >500kV, two circuit breaker are connected in series for switching such high voltages, i.e. the total voltage to be switched needs to be shared equally by the two switches. Because of the required capacitance the capacitor and hence also the switchgear is big, especially of great diameter, and costly. According to the present invention shields 10, 11 are arranged in order to form additional capacitors C 1 ", C 1 ''' and C 2 between the shields 10, 11 and between a connecting means 4, connecting the two switches 2, 3, and the enclosure 5. The resulting switchgear 1 has increased dielectric strength and the total voltage is essentially equally shared by the two switches 2, 3 in series.

    摘要： A combined disconnector-earthing switch device is shown which comprises, in an enclosure (4) having at least three openings (12, 13, 14) for contacting the switch with a circuit breaker and at least one line, at least
    -a first metallic part as a first disconnector terminal (1) held by a first insulator (6),
    -a second metallic part as a second disconnector terminal (2) held by a second insulator (7),
    -an earthing contact (3),
    -a movable contact being electrically connected to the second part (2) and being able to electrically connect either first (1) and second disconnector terminal (2) or earthing contact (3) and second disconnector terminal (2),

    whereas the first disconnector terminal (1) has at least two separate contacts (8, 9) on the surface of the disconnector terminal which contacts are oriented towards different openings (12, 13) of the enclosure so that by attaching a connector to one of that contacts an electrical connection to the respective opening is established.
    Thus, a combined disconnector-earthing switch device which is suitable for more than one configuration of lines/bushings and circuit breakers is provided.
