This series of models are specially developed for oil purifier and vacuum pumping requirements of 220 / 500 / 750kV and above power transmission and transformation equipment.

It is mainly used for the purification of insulating oil to remove its moisture, gas and mechanical impurities, so as to improve the withstand voltage strength and oil quality of insulating oil and ensure the safe operation of high-voltage electrical equipment. The treated oil reaches the national standard and is a common oil filtration equipment in the power industry.

● it is used for construction, installation, maintenance and on-site overhaul of UHV power transmission and transformation equipment.

● it is used for deep purification of oil products such as capacitors, mutual inductors and UHV transformers.

● it has the functions of transformer refueling and oil replenishment.

● used for circulating drying of transformer.

● it can realize transformer vacuum pumping and vacuum oil injection at the same time.

● it adopts two-stage high vacuum design, which makes it more advantageous to use this series of models in high altitude areas.

● high efficiency of water removal and degassing: the patented three-dimensional evaporation degassing and dehydration system of Dingneng is adopted, and the unique stainless steel folding cyclone separation tower is adopted to increase the separation area and make the oil film. The built-in secondary evaporation compartment and special vacuum filler increase the oil film contact area and quickly separate the water and gas in the oil, with very high efficiency. (Patent No.: 2014202545183)

● strong impurity removal ability: high β Value precision filter material, multi-stage filtration and step-by-step encryption to remove fine particles in the oil. The filter element has large volume and large sewage holding capacity. Long service life, and equipped with automatic detection function of filter element pollution.

● short oil treatment time: the two-stage high vacuum and high pumping speed can quickly and efficiently remove the water vapor in the oil, greatly improve the drying degree and breakdown voltage of the oil, and shorten the oil treatment period, so as to improve the service performance of the oil.

● uniform heating: the system adopts low-density indirect circulating carbon fiber heating technology to prevent acetylene gas from oil cracking. Low energy consumption, uniform heating and stable oil temperature.

● automatic control: the machine adopts high-end and sophisticated configurations such as automatic constant temperature control, photoelectric liquid level control, automatic defoaming control and automatic pressure protection to ensure that the equipment does not inject oil during operation and operates safely and stably.

● interlocking protection: overload protection, overpressure alarm shutdown protection, oil shortage protection, fuel injection protection, phase sequence protection, etc. ensure the reliable operation of the whole machine for a long time.

● humanized indication: automatic design, and there are oil temperature, pressure, vacuum degree, filter element pollution degree, operation status and other indications, which are concise and clear.

● modern design: This machine has advanced oil purification process design, which can be processed online or offline. It has a high degree of automation and can realize unattended operation. The equipment has compact structure and flexible and convenient movement.  

● good comprehensive performance: the machine has the advantages of low noise, simple operation, long maintenance interval, low energy consumption, low operation cost and high oil purifier efficiency.
