A parallel winding voltage-regulating apparatus includes a transformer whose voltage-regulating side consists of two parallel main windings, which are electric coupling through balancing reactor. The two main windings are tapped in the order of voltage value and connected sequentially to a stationary contact of a tap changing switch. A movable contact touches the two adjacent stationary contacts during a static output to achieve parallel supply of power without voltage interruption and circulation current. The present invention can be used for voltage-regulating on-load in substation or distribution, single-phase or multiphase compensation voltage-regulating and stabilizing, voltage stabilizing in house, voltage-regulating of electric furnace to control temperature, voltage-regulating of motor to control speed. Moreover, it can be used as DC voltage-regulating apparatus with large power and high efficiency if it is provided with rectifying device and filter. |
