Product Introduction

Technical Data

S11(13)-M.ZT distribution transformer on-load automatic tuning capacitor is the distribution transformer with large and small rated capacity automatic tuning controller automatically detect judgment according to the user load size and trough a special load capacity regulating switch to auto switch two kinds of transformer capacity under the transformer is not the state of the power outage to realize automatically adjust size in the process of running transformer capacity.

Fundamental Principles

When the distribution transformer on-load automatic tuning capacitor is at the large capacity,three-phase high voltage windings into delta connection with low voltage winding parallel structure ;When at the small capacity.Three-phase high voltage windings in y connection with low voltage winding tandem structure.

Transformation of angle joint and star joint of high voltage windings and transformation of series connection and parallel connection of low voltage windings are finished by on-load capacity switch which is decided by automatic controller according to the size of load of detection.

When the large capacity transforms into the small capacity of transformer.the core magnetic flux density slashjoss of silicon steel sheet smaller and no-load loss and no-load current also fell sharply which lead to greatly reduces the transformer no-load reactive power loss and wattful loss in the result of reaching reducing consumption.
