<p>PURPOSE:To enable a rational division, and to obtain the compact transformer by collecting neutral-point side terminal drawn out of the main windings of unit transformers in three pairs and connecting the pairs to three sectors of an on- load tap changer for changing over three phases. CONSTITUTION:The neutral point sides of the main windings 2 received in each unit transformer 1 are collected in three blocks in the numbers of three, three and two, collected at every block, and connected to each tap winding 4-1-4-3 of an on-single-phase load voltage regulator 3 through connecting ducts 7. On the other hand, these tap windings 4-1-4-3 are connected to each sector 6-1-6-3 of the on-load tap changer 5 for changing over three phases. Accordingly, the number of a main transformer proper divided can be optimized judging from an aspect of the size of transport, and the transformer is manufactured economically and compacted.</p> |
