Abstract

The invention belongs to the technical field of electric transformers, and particularly relates to a line outlet structure of an internal water cooling phase-shifting transformer. The structure comprises three phases of iron cores. Each iron core is sleeved with multiple valve side windings (2) and multiple line side windings (3). Both the valve side windings (2) and the line side windings (3) are sequentially arranged from top to bottom. The line outlet structure is characterized in that each valve side winding (2) or each line side winding (3) is formed by winding a single hollow wire (0) or multiple parallel-connected hollow wires (0), the start end (01) and the tail end (02) of each hollow wire (0) are each provided with a water path line outlet terminal (12), the start end (01), the tail end (02) and the middle (03) of each hollow wire (0) of each valve side winding (2) are each provided with a circuit line outlet terminal (13), and the start end (01) and the tail end (02) of each hollow wire (0) of each line side winding (3) are each provided with a circuit line outlet terminal (13). According to the line outlet structure of the internal water cooling phase-shifting transformer, the structure is compact, wiring is convenient, and the size of the internal water cooling phase-shifting transformer can be reduced.

Description

technical field [0001] The invention belongs to the technical field of power transformers, and more specifically relates to an outlet structure of a water-internal cooling phase-shifting transformer. Background technique [0002] At present, the outlet wires of the network side winding and the valve side winding of phase-shifting transformers on the market are respectively located on both sides of the iron core, and the outlet terminals of the valve side windings are bolts; There are circuit outlet terminals and waterway outlet terminals, the number of outlet terminals is large, and the outlet structure is complicated. The outlet structure of the existing phase-shifting transformer cannot meet the requirements. Therefore, it is necessary to provide a structure different from the outgoing line of the existing phase-shifting transformer to meet the outgoing line requirements of the internal water-cooled phase-shifting transformer. Contents of the invention [0003] In order...
