What is the power frequency transformer without partial discharge test?
The power frequency non-partial discharge test transformer is mainly used to check the insulation level of various insulating materials, insulation structures and electrical products to withstand the power frequency voltage, and is also used as a power source for partial discharge power frequency test of transformers, transformers, lightning arresters and other test products . Widely used in electrician manufacturing department, electric power operation department, scientific research unit and colleges and universities. The main technical performance of 50 ～ 500KV power frequency non-partial discharge test transformer is in the domestic leading position, reaching the advanced level of similar international products.
Power frequency non-partial discharge test transformer has strong configurability, complete voltage capacity series and perfect functions; it adopts epoxy insulation tube without partial discharge, which has small partial discharge; low impedance voltage, which is better than the national standard; automatic control technology is used to achieve a high degree of automation , Strong anti-interference ability; Fast electronic protection device, high reliability. Power frequency non-partial discharge test transformer is suitable for power frequency, large factories and mines, scientific research units 220kV and below voltage level power equipment (such as power transformers, switching equipment, capacitors, transformers, etc.) for power frequency AC withstand voltage test, various electrical Partial discharge test of equipment (such as cables, large transformers, transformers, GIS combined appliances, etc.).
The power frequency non-partial discharge test transformer can be widely used in the field of power system users to test the insulation performance of various high-voltage electrical equipment. It is especially suitable for the research and use of large enterprises and research departments. It is a product developed in combination with the process structure of oil-immersed test transformers and insulated barrel reactors. Large size and heavy weight. The power frequency non-partial discharge test transformer is an indispensable thing in the high-voltage laboratory, filled with high-insulation strength insulating oil as the insulating medium; the shell is fired with epoxy glass wire, and the insulation strength and compressive strength are higher than other materials.
Power frequency non-partial discharge test transformer is large in size, heavy in weight, high in technology, beautiful in appearance, and atmospheric; adopts DQ130-30 grain oriented silicon steel sheet, 45 ° full oblique joint lamination, product waveform distortion rate and no-load current are similar The domestic product is small; the impedance voltage is ≤5%, which is better than the national standard and meets the requirements of the pollution experiment; fully automatic microcomputer control, high intelligence, perfect function, strong anti-interference ability; can effectively eliminate clutter interference in the power supply . Power frequency non-partial discharge test transformer automatic measurement technology, voltage, current, partial discharge measurement accuracy is high; software and hardware multiple overvoltage, overcurrent protection, rapid action and high reliability.
