DEVICE FOR GENERATING HIGH VOLTAGE IN THE CONTROL OF CATHODE-RAY TUBES

摘要

It is disclosed a high-voltage generating device to be used in the control of cathode-ray tubes in which a flyback transformer (2) and a potentiometer (4) are respectively housed in a holding structure (3) and a housing body (5) that are directly linked to each other. The device further comprises an air space (7) interposed between the flyback transformer (2) and potentiometer (4) in order to limit the heat flow from the potentiometer to the transformer. The device as a whole is therefore capable of generating higher powers as compared with the same devices of the known art, the inner temperature of the transformer being the same.
