| description | A secondary side voltage regulator for power transformer is provided, wherein at least one central tap 3 is arranged on a, b and c phase of the secondary coil winding 1 of a power transformer; the central tap on each phase is connected respectively with the corresponding fix contact 5 on each phase of an on-load voltage regulating switch 2; the terminal 4-2 of a three-phase moving contact on the on-load voltage regulating switch is connected at the omicron position of a zero line. The utility model solves the problems that energy is wasted under light load, and electrical equipments are difficult to be started under heavy load. The utility model also has the advantages of low requirement on the insulating strength of on-load voltage regulating switches, low entire cost, small volume and safe convenient use. |
