ELECTROMECHANICAL PROTECTIVE INTERLOCKING FOR MOTOR-DRIVEN STEPPING VOLTAGE REGULATORS

摘要

The interlocking is used in power transformers, the voltageof which is adjusted under load. It has reduced overall dimensionsand greater safety in operation. The shaft is protected by anaxially positioned tube around it and is frontally covered by alever-plate fitted in a lateral slot in the tube and isfunctionally connected to an electric breaker. In the uncoveredpart of the hole in the tube there is a front cog of a handleinserted in the tube.3 claims, 6 figures
