This product adopts high-purity mineral insulating oil with excellent insulation performance and heat dissipation efficiency. The sealed oil tank design effectively prevents oil leakage and ensures long-term stable operation. It is equipped with built-in over-current and over-voltage protection devices to ensure the safety of the testing process. The compact size and lightweight design make it easy to carry and install, and it can be matched with small mobile test vehicles. The simple operation interface reduces the professional threshold for operators, and no professional training is required for basic testing work.
The transformer adopts 380V three-phase 50Hz input voltage, with no-load current less than 0.5% and insulation resistance greater than 1000MΩ. It complies with the national standard GB/T 19494.1, with an output voltage error of less than ±1%. The overall dimensions have a tolerance of ±3%, and the net weight meets the relevant national safety standards. It is equipped with detachable high-voltage wiring terminals and insulating operating rods, which can meet the wiring needs of different testing scenarios. The oil tank is made of high-strength cold-rolled steel plate, with good corrosion resistance and service life.
It is suitable for withstanding voltage tests of small and medium-sized power distribution equipment in power distribution rooms, temporary on-site detection of electric construction teams, power training experiments in colleges and universities, aging tests of low-voltage electrical components, and safety detection of household power equipment. It is an ideal test equipment for small-scale power testing scenarios with high mobility requirements.
