Inflatable High-Voltage Test Transformer


With the progress of basic scientific research in China, the application of new materials and new processes has introduced the new medium sulfur hexafluoride gas into the field of power equipment applications. Due to the excellent insulation performance, arc extinguishing performance, and non-flammability of sulfur hexafluoride gas, it has been widely used as a new insulating medium.

After years of efforts, our company has successfully developed the inflatable light-duty test transformer. Compared with traditional oil-immersed light-duty test transformers, this series of products is 20%-60% lighter in weight (depending on voltage and capacity levels), and has no oil pollution. The voltage level of a single test transformer can reach 300KV. Due to the adoption of new production processes, the technical performance of the products has been greatly improved, making them particularly suitable for on-site work and frequent mobile working conditions.

Structure




1. The design concept, material selection, and process flow of the YDQ series products are all new. Therefore, they are not only small in size, light in weight, and beautiful in appearance, but also all technical indicators meet the requirements of the standard. The YDQ series products use high-quality cold-rolled DQ-151 oriented silicon steel sheets stacked into a multi-stage cylindrical frame iron core, and use QZ type wires to directly and continuously wind the high-voltage tower coil on a specially made high-strength insulating cylinder. The shell is of suitable size and filled with SF6

gas.

2. The difference between YDQ (JZ) products and YDQ products is that the high-voltage rectifier silicon stack is cleverly installed inside the high-voltage sleeve. By inserting and extracting the short-circuit rod, it can be switched between industrial frequency high-voltage AC output and high-voltage DC output.
