摘要:A system for reducing the voltage of an AC electrical supply to a load for thepurpose of energy efficiency, comprising a transformer and power converter in circuitbetween an AC electrical supply and a load, and a bypass switch S to cause the
transformer to be taken out of circuit and to connect the electrical supply to the load inthe event of a sustained overload of the transformer. The system includes means (14) tomeasure the temperature of the transformer, means (17) to measure the electricalcurrent in the circuit and control means (15) receiving signals from the sensors (14, 17)and to operate bypass switch S to bypass the transformer and allow it to cool. A fuse F2and thermal cut out device (16) are in circuit with the secondary winding of thetransformer as failsafe means to interrupt the supply to the transformer in the eventthat the bypass switch fails to operate.
