| Zusammenfassung: | A connecting method of loading voltage regulation switch with the secondary side of electric power transformer sets at least one middle tap at each phase of secondary coil winding. The middle tap at each phase connects with corresponding contact at each phase of loading voltage regulation switch separately. The connections of three phase active contact connecting end are gathered to zero line place. It solves the problems of waste energy in light loading condition and not easy to start the electricity consumping equipment in heavy loading condition. |
