ZYD Series Double Stage Vacuum Transformer Oil Purifier

1. The polymer magnetic material imported from Germany is used as the filter material, multi-stage precision filtration, and step-by-step encryption to ensure high filtration accuracy, so that the particle size of impurities after filtration is ≤1~3μm, and the cleanliness is ≤6 grade.

2. Adopting the combination of three-dimensional flash evaporation technology and UK technology, and using high-efficiency degassing components, the water and gas in the oil can be quickly separated, and the degassing and dehydration efficiency is high. After treatment, the water content in the oil is ≤3ppm, and the gas content is ≤0.1 %. This system is maintenance-free.

3. The equipment is equipped with advanced liquid level controller, which can automatically adjust the oil inlet and outlet balance, which can effectively prevent the idling of the oil pump, and truly achieve the separation of man and machine, making the operation more convenient and reliable. And it has three-in-one interlocking automatic safety protection function to avoid adverse effects caused by misoperation and sudden shutdown.

4. The filter is equipped with automatic sound and light pressure difference alarm device. When the filter element is clogged and the pressure reaches a certain value, it will automatically send out  sound and light alarm signal to protect the normal operation of the equipment.

5. The domestic well-known brand electrical appliances are used as the main control components, so as to fully guarantee the high-performance continuous operation of the equipment without failure.

6. Infrared gradual heating is adopted to form safe and reliable heating system. The optimized pipeline design ensures that there is no "dead oil zone", and a reliable temperature sensing control system and fluid monitoring device are installed to ensure that the heater does not overheat and  no dry burning. The safety performance is several times that of ordinary heating methods, and the oil temperature can be adjusted arbitrarily between 0 and 100ºC, and the oil is heated at a constant temperature. At the same time, according to different climates, there are two heating methods, automatic and manual, for selection.

7. The machine is equipped with double-stage vacuum with large pumping rate, which can increase the oil breakdown voltage by 35KV at one time, reduce the damage of oil aging caused by repeated heating, and shorten the oil treatment period.

8. Adopting special precision oil pump, it runs smoothly in vacuum state, has strong suction energy, low noise, and meets environmental protection requirements.

9. In addition to normal oil filtering, it can also perform online oil filtering on transformers (that is, it can be processed without stopping the transformer), and has the functions of vacuum oiling and vacuum drying of transformers.
