The product uses high-quality silicon steel sheets with high magnetic permeability, which reduces no-load loss and operating noise. It adopts high-purity mineral insulating oil with strong insulation performance and good heat dissipation. It is equipped with built-in voltage and current protection devices, with manual and semi-automatic operation modes. It is equipped with rolling wheels, which is convenient for moving between different test stations. The high-strength insulating sleeve has good insulation performance and can effectively avoid discharge accidents during the testing process.
It adopts 380V three-phase 50Hz input voltage, with no-load current less than 0.3% and short-circuit impedance error less than ±2%. The insulation strength is greater than 60kV/min, and the output voltage accuracy reaches ±1%. The overall dimensions have a tolerance of ±5%, and the net weight meets the relevant national safety standards. It is equipped with an oil temperature gauge and a pressure gauge, which can monitor the operating status of the transformer in real time. The wiring terminals use copper materials with high conductivity, which can ensure stable power transmission during the testing process.
It is suitable for finished product testing of medium-sized power equipment manufacturers, fixed test stations in power maintenance centers, batch testing of high-voltage switchgear, withstand voltage testing of power metering equipment, and testing of high-voltage electrical components in power distribution networks. It is an ideal testing equipment for medium and large-scale power testing scenarios with high stability requirements.
