Abstract

1373866 Vacuum variable capacitors ENGLISH ELECTRIC VALVE CO Ltd 4 Oct 1973 [6 Oct 1972] 46179/72 Heading H1M The vacuum envelope of a vacuum variable capacitor comprises glass sleeve 1, metal members 2, metal end plates 21, 23 and, to allow axial motion of mobile electrodes 3, bellows 22, a further bellows 6 connected between end plate 21 and mobile electrode carrier member 5 and located within the vacuum envelope being of relatively large diameter so as to provide a low impedance path for current flowing through the capacitor. Vacuum-retaining bellows 22 which carries only a small proportion of the current can accordingly be of small diameter and therefore less vulnerable to the pressure difference on either side thereof. The actuation mechanism accordingly requires only a low torque and is suitable for motor control.
