摘要： The switching point in a high- or medium-voltage switch contains two fixed contact members (1, 2), a rotating, electrically conductive bridging contact member (3), and a drive for moving the bridging contact member (3). When the switching point is closed, the bridging contact member (3) is fit in between the fixed contact members (1, 2) and short-circuits them. The drive is composed of two coils (5, 6) which surround the bridging contact member (3) and are arranged in such a manner that the bridging contact member (3) can be caused to rotate by a current in a respective one of the coils. The energy which needs to be applied to rotate the bridging contact member is less than for contact members which move in translation in comparable switching points. The energy required for opening and closing the switching point is thus reduced.

摘要： The current-limiting switch (S) has an arc-resistant contact arrangement (K1), which is intended to carry the rated current (IN), of a first switching point (S1), and two commutation paths (P1 and P2) connected in parallel with the first switching point (S1). The first commutation path (P1) contains, in series, a contact arrangement (KT) of a second switching point (ST) and an electronic power switching apparatus (T). The second commutation path (P2) contains, in series, a switching apparatus (SA) and a current-limiting element (RB). The contact arrangements (K1 and KT) are designed to be coaxially symmetrical and are arranged in a pressure-resistant housing (G). Both switching points have electrodynamic drives which open and close very quickly. Thanks to the extremely space-saving, coaxial arrangement of the contact arrangements, undesirable stray inductances can be avoided. This allows the current-limiting switch to be switched on and off very quickly.

摘要： The switching point in a high or medium voltage switch contains two stationary switch pieces which are of cylindrical design and led coaxially into one another, to form an annular gap. A movable bridge switch piece constructed in the form of a contact ring fits into the annular gap when the switching point is closed. An electrodynamic drive comprising two coils moves the contact ring in the axial direction. By virtue of the low mass of the contact ring, the single moving part of the switching point can be switched on and off very quickly and efficiently.
