Test transformer, also known as booster, is a must-have equipment for testing the electrical strength of power supply equipment, various electrical products and insulation tools.
The YDG series of dry test transformers produced by our company has completely changed the backward state of the old-fashioned test transformers: stupid, large, and heavy, and can provide DC high-voltage test power after equipped with high-voltage silicon stacks produced by our company. Boxes (tables), automatic protection of micro-ampere meter, ball gap and other ancillary equipment, especially for on-site testing, so that the heavy work becomes easy, fast, easy and flexible, and greatly improved efficiency. Therefore, it is very popular with power systems and high-voltage testers of large factories and mines.
structure:
This series of products, because the design concept, material selection and process are all new, so without reducing performance, minimize the size and weight.
5KVA/50KV Dry AC/DC High Voltage Test Transformer Utilizes advanced production equipment, adopts coil winding epoxy vacuum casting and CD type iron core wound with high quality cold rolled silicon steel, effectively weakens the leakage flux, and does not perform DC withstand voltage test. An external silicon reactor is required, and only direct current high-voltage silicon stacks supplied by our company can be installed on the high voltage side to obtain direct current.
working principle:
This series of product input voltage is 200V or 400V connected to the supporting control box (Taiwan), by the auto-regulator to adjust the input voltage to the test transformer primary winding (low voltage), the use of electromagnetic induction principle, in the secondary winding (high pressure) The ratio of the number of turns to the number of turns of the primary winding can be used to obtain an output voltage of the same multiple, continuously adjustable from zero volts to the highest rated value. For DC withstand voltage and leakage current testing, as long as the high-pressure silicon stack installed in the high-voltage output, you can obtain DC high voltage, its amplitude is 1.414 times the power frequency high voltage value.
