YDQ-50KVA/100KV Fully Automatic Lightweight High Voltage Test Transformer

YDQ-50KVA/100KV Fully Automatic Lightweight High Voltage Test TransformerAfter years of effort, our company has successfully researched and developed an inflatable lightweight test transformer. Compared with traditional oil immersed lightweight test transformers, this series of products reduces weight by 20% -60% (depending on voltage and capacity level), and has no oil pollution. The voltage level of a single test transformer can reach 300KV. Due to the use of new production processes, the technical performance of the product has been greatly improved, making it particularly suitable for on-site work and frequent mobile working conditions

1. The design concept, material selection, and process flow of the YDQ test transformer series products are all brand new. Therefore, not only is it small in size, light in weight, and beautiful in appearance, but all technical indicators have met the standard requirements of<-98>. The YDQ series products are made of high-quality cold-rolled DQ-151 oriented silicon steel sheets stacked into multi-stage cylindrical frame shaped iron cores, which are directly and continuously wound with QZ type wires on a specially designed high-strength insulation cylinder to form high-voltage tower coils. The shell is of a conformal size, filled with SF2 and YDQ (JZ). The difference between YDQ products and YDQ products lies in the clever installation of a high-voltage rectifier silicon stack inside the high-voltage sleeve, which can be converted into a power frequency high-voltage AC output or a high-voltage DC output through the insertion and extraction of a short-circuit rod

YDQ-50KVA/100KV Fully Automatic Lightweight High Voltage Test Transformer

One high-voltage test transformer and one control box (set) are used as a complete set, and the control box is used for voltage regulation and control.

This series of products has 200V series tap, which can be cascaded with two or three units to form AC 100KV, 150KV, 200KV, 300KV, DC 140KV, 210KV, 280KV, 420KV high voltage. And according to user needs, 5-15KV medium voltage taps can be extracted from the high-voltage winding for AC withstand voltage testing of high-voltage motors.
