Product Name: QJA-S Series Ultra High Pressure and Ultra High Pressure Oil Vacuum Filter, Model ZJA before Upgrade

Product Overview:

This series of models is a specialized equipment developed specifically for oil filtration and vacuum extraction requirements of 220/500/750KV and above power transmission and transformation equipment.

Mainly used for purifying insulating oil, removing its moisture, gas, and mechanical impurities, thereby improving the withstand voltage strength and oil quality of insulating oil, ensuring the safe operation of high-voltage electrical equipment. The processed oil meets the national standard for use and is a commonly used oil filtration equipment in the power industry.

Product Usage:

Used for the construction, installation, maintenance, and on-site inspection of ultra-high voltage transmission and transformation equipment.

Used for deep purification treatment of oil products such as capacitors, transformers, and ultra-high voltage transformers.

● Equipped with the function of refueling and replenishing oil for transformers.

Used for circulating drying treatment of transformers.

It can achieve transformer vacuum pumping and vacuum oil injection at the same time.

Adopting a dual stage high vacuum design, this series of models has more advantages when used in high-altitude areas.

Product advantages:

High efficiency in water and gas removal: The three-dimensional evaporation degassing and dehydration system using Dingneng's patented technology, along with a unique stainless steel folding cyclone separation tower, increases the separation area to make the oil thin film. Built in secondary evaporation layer, combined with special vacuum packing, increases the contact area of the oil film, quickly separates water and gas in the oil, and has significantly higher efficiency than similar products. (Patent number: 2014202545183)

Strong impurity removal ability: High beta value precision filter material, multi-stage filtration with step-by-step encryption, removes fine particles from the oil. The filter element has a large volume and a large dirt holding capacity. Long service life and equipped with automatic detection function for filter contamination.

Short oil processing time: Double stage high vacuum and high pumping speed can quickly and efficiently remove water vapor from the oil, greatly improving the dryness and breakdown voltage of the oil. After one filtration, the effect is greatly improved, shortening the oil processing period and thus improving the performance of the oil.

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

● Automation control: This 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 spray oil during operation and operates safely and stably.

Interlocking protection: overload protection, overpressure alarm shutdown protection, fuel shortage protection, fuel injection protection, phase sequence protection, etc. ensure the long-term reliable operation of the whole machine.

● Humanized indication: Automated design, with indications for oil temperature, pressure, vacuum degree, filter contamination, operating status, etc. The labeling is concise and clear.

Modern design: The oil purification process of this machine is designed with advanced technology, which can be processed online or offline. It has a high degree of automation and can achieve unmanned operation. The device has a compact structure and is flexible and convenient to move.

● Good comprehensive performance: This oil filter has the advantages of low noise, easy operation, long maintenance intervals, low energy consumption, low operating costs, and high oil filtration efficiency.
