摘要： This invention relates to electrical automatic systems able to restore the reference values of the AC variable voltage.
The system of power circuit-breakers provides protection of an AC voltage regulator. A double-pole power circuit-breaker 21 is connected so that its first contact is made between the input of the mains phase conductor and the point of connection of the input of a regulating unit 2 and one of the outputs of a shunt release 22, which is the input of an additional protection unit 16 made as a diode bridge 17 whose output is connected to power electrodes of a protection thyristor 18. The second output of the shunt release 22 is connected to the input of the diode bridge 17, the second contact of the double-pole power circuit breaker is connected between the output of the regulating unit 2 and a point of connection of a load 3 and an output capacitor 15, thereby forming a triple-pole circuit-breaker the contacts of which are connected in a specific circuit between the second end of the transformer primary winding and mains 1.
A stand-by double-pole power circuit-breaker 26 is connected between the mains and the load, and a remote control button 27 is connected between the first output of the shunt release 22 of the double-pole power circuit-breaker and the neutral conductor.
Disclosed are the embodiments of an AC voltage regulator providing the step-down, step-up; step-up and step-down modes of operation for a separate voltage regulator and a voltage regulator in a cascade circuit with extended protection and service functions along with the improvement of some units.
