Inflatable High-Voltage Test Transformer


With the progress of basic scientific research in our country, the application of new materials and new processes has pushed the new medium sulfur hexafluoride gas into the application field of power equipment. 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 lightweight test transformer. Compared with the traditional oil-immersed lightweight test transformer, this series of products has a weight reduction of 20%-60% (depending on the voltage and capacity level), and is free of 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, especially suitable for on-site work and frequent movement under 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-shaped 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 the YDQ (JZ) product and the YDQ product is that the high-voltage rectifier silicon stack is cleverly installed inside the high-voltage sleeve, and by inserting and extracting the short-circuit rod, it can be switched between industrial frequency high-voltage AC output and high-voltage DC output.
