There are so many advantages to use synthetic ester transformer insulating oil!
November 06, 2021
With the overall development of the power grid system, the rapid development of transformers has also been promoted, and higher requirements have been put forward on the transformer industry, which must be more stringent for the quality of transformer insulating oil. Therefore, the matching high-quality transformer insulating oil also needs to be quickly upgraded to keep up with the pace of development of the power industry. Synthetic ester transformer insulating oil is a compound product of acids and alcohols. It can be applied to transformers installed in densely populated areas. Its characteristics are safety, space saving, environmental friendliness, and long life. The only thing is that the price is slightly more expensive than mineral oil transformer oil.
1. Improve safety: Synthetic ester transformer insulating oil can be mixed with any other oil in different cases, such as mineral oil. It can better protect the environment and the safety of residents. Its excellent oxidation resistance can be used in high-temperature applications. Under the conditions, the viscosity is more stable, the fluidity is better, and the heat dissipation is better. 2. High flash point: Compared with mineral oil, synthetic ester transformer insulating oil provides another choice for flame-retardant fluid. The ignition point of synthetic ester transformer insulating oil is 300 ℃, while mineral oil is 170 ℃. Synthetic ester transformer insulating oil has higher fire safety, so it can be used in more occasions, such as urban buildings. Can strengthen the overall safety of the building. The application and development of synthetic ester insulating oil can greatly reduce the risk of transformer fires, and at the same time, the area required for construction is greatly reduced due to the reduction of firewalls. 3. Environmentally friendly and degradable: Synthetic ester insulating oil is non-toxic and degradable in the soil. Even if it leaks, it will not harm the environment or cause pollution to water sources. Its environmental properties are unmatched by mineral oil. 4. Long-term efficiency and low maintenance: Due to the safety of synthetic ester insulating oil, it helps the global power grid to improve the effectiveness of the system and save management costs. 5. New energy-saving technology: mineral oil-type transformer insulators need a firewall, while synthetic ester transformer insulating oil does not even need a firewall. It only needs to ensure a safety distance of 1.5 meters, which reduces the land area and building area. In urban construction, in order to reduce the area required for fire protection measures, synthetic ester oil-immersed transformers can be installed and used in underground spaces, saving a lot of costs and enhancing aesthetics. In addition, synthetic ester transformer insulating oil has a high ignition point, which means that it can be used at higher temperatures, so as to increase the capacity of the transformer without increasing its size. 6. Reduce installation and maintenance costs: reduce indirect costs and reduce maintenance costs by reducing auxiliary equipment such as fire protection systems, which helps to reduce maintenance costs. In addition, the study also shows that, due to the excellent moisture resistance of synthetic ester transformer insulating oil, it can significantly extend the service life of insulation materials. Compared with mineral oil, its service life is increased by about 15% on average. 7. Good water resistance: laboratory studies have shown that even if the moisture content of synthetic grease transformer insulating oil exceeds 600ppm, the breakdown voltage of synthetic ester is still maintained at 75kv, and even a very small amount of water in mineral oil will cause breakdown The voltage deteriorates rapidly and problems occur, causing damage to the equipment transformer. 8. High temperature overload protection: The high ignition point of the synthetic ester transformer insulating oil enables it to withstand more than 20% overload, which prolongs the running time of the transformer and improves the efficiency of the energy system. In addition, transformers with high temperature rise can also be designed for special occasions, and the low ignition point characteristics of mineral oil means that high-temperature operation is relatively less reliable than synthetic grease insulating oil. A major consideration for future urban development is whether the use of new solutions can improve existing infrastructure without causing power outages or disturbances. One of the main benefits of using synthetic ester or natural ester transformer insulating oil is that they can be retrofitted to existing mineral oil transformers, and the transmission and distribution network can be modified to meet new demands without any major changes. At present, the energy consumed by cities accounts for 70% of the global energy, and it continues to grow. This means that safer and more sustainable power transmission equipment and systems are needed. Adding synthetic ester transformer insulating oil to the transformer can protect the surrounding environment and It can reduce maintenance and installation expenses, and improve the efficiency of power distribution and transmission.
