Embodiment Construction
[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0045] A lightning protection type on-load capacity-regulating transformer, including three-phase high-voltage windings, three-phase low-voltage windings, on-load capacity-regulating switches and other metal and non-metal structural parts constituting the transformer, the on-load capacity-regulating switch switches the capacity-regulating transformer When it is in a state of large capacity, the winding adopts a Dyn11 connection; when the on-load capacity regulating switch switches the capacity regulating transformer to a small capacity, the winding adopts a Yzn11 connection.
[0046] Specifically, the low-voltage winding of each phase includes two sections of coils with the sa...
