The Impact Of Transformer Insulating Oil Quality On Solar Power Plants

Writer： Kaiqian Oil Purifier Release time：2025-11-03 16:12 Clicks：

   Solar power plants are typically located in areas with abundant sunlight. Some power plants are situated in high-temperature, windy, or humid environments. These harsh conditions place higher demands on transformer operational stability. Transformer insulating oil not only performs the crucial function of insulation and cooling, but also suppresses arcing and dissolves impurities. However, over long-term operation, insulating oil is susceptible to contaminants such as moisture, gas, and mechanical impurities, leading to oil quality degradation. Moisture reduces the oil's dielectric strength and can cause partial discharge; excessive gas content accelerates oil oxidation and aging, shortening the transformer's service life; and impurity accumulation can clog the cooling system, affecting heat dissipation efficiency. In severe cases, this can even cause transformer failure, resulting in widespread power outages and significant economic losses for the power plant.

Compared to traditional oil filtration equipment, transformer insulating oil vacuum purifiers offer three core advantages in solar power plant applications:

1. Efficient purification, profound oil quality improvement

  This equipment utilizes a dual purification process of "vacuum dehydration and degassing + precision filtration" to rapidly break the gas-liquid equilibrium in insulating oil under vacuum conditions, efficiently separating harmful gases such as dissolved water, hydrogen, and methane. A multi-stage precision filtration system also removes contaminants such as mechanical impurities and colloidal particles. The treated insulating oil can increase breakdown voltage by over 30%, significantly reduce dielectric loss, and control moisture content to below 5ppm, providing reliable insulation protection for transformers.

2. Energy savings and consumption reduction, adapting to the green power plant concept

  Solar power plants prioritize "green power generation," and transformer insulating oil vacuum purifiers are designed to fully meet this need. Utilizing a high-efficiency, energy-saving motor and an optimized oil circulation system, the equipment saves over 20% energy compared to traditional oil purifiers.

3. Stable and durable, adaptable to complex on-site environments

  Given the remote locations and complex environmental conditions of many solar power plants, the transformer insulating oil vacuum filter has been specially optimized in its structural design. The body is constructed of corrosion-resistant steel, effectively resisting erosion from harsh environments such as wind, sand, and salt spray. The control system features intelligent temperature and humidity compensation, ensuring stable operation within a wide temperature range of -20°C to 50°C. Furthermore, the device is equipped with a remote monitoring module, allowing operators to view real-time equipment operating status and oil quality data via a mobile app, enabling unmanned operation and maintenance, significantly reducing on-site maintenance pressure.
