Insulated carrier for securing vacuum-contactors especially of medium voltage control and switch-gear

摘要

The insulating carrier for vacuum operated switch is formed from a flat-bed type moulded plastics section having one end region fitted out with a first fixture limb for releasable connection to the vacuum switches and the other end fitted with a second fixture limb for releasable connection, via screw bearings, to the control- and switch-gear. The insulating carriers accommodate the vacuum-contactors via pole couplings (PS) which are fitted with a mirror-image arrangement of vacuum-contactor fixture lugs (VB1,VB2) for releasable connection to the vacuum-contactors. The pole couplings have a number of encircling transverse fins (QR) matched to the voltage ratios of the vacuum-contactors.
