HV generation component for use with TV projection tube - has pair of capacitors in series with each housed in separate chamber within plastics material housing

摘要

Special display tubes, such as those used for projection, have capacitors of 3 nF capacity capable of operating with 35 kV. The capacitor is provided by two capacitors in series (C1,C2) housed in separate chambers within a housing (14). The housing is formed by two half sections (15,16) that have comb shapes and fit together to form the chambers (17,18). An interconnecting path (19) is provided for the capacitors and contacts (21,22) for external connection are provided. ADVANTAGE - HV capacity. Avoids need for embedding in resin.
