Future development trend of synthetic ester transformer insulating oil
September 19, 2022
It is estimated that by 2050, about 70% of the world's residents will live in cities, and there will be many cities with a population of over 10 million. The rapid development of the city and the industry and commerce corresponding to the growing population all require huge energy to support, and the power transmission and transformation of the power industry and the distribution and transformation system of the industrial system play an indispensable role in it. However, The current market demand has far exceeded its power distribution supply capacity. In order to reduce the risk of power outages and ensure a high level of power supply in cities, governments around the world are taking different measures to innovate power grids to varying degrees to ensure reliable power supply. In order to promote the integration process of power grid business and energy, the information collection of traditional energy, new energy, energy saving, environmental protection, high-efficiency energy and advanced equipment has always been the goal of each power grid.
As the key equipment of the power grid, the transformer plays a role in the power transmission and transformation system to increase the voltage level and the power transmission and transformation capacity. The transformer market has always maintained a huge growth. With the comprehensive development of the power grid system, the rapid development of transformers has also been promoted, and higher requirements have been placed on the transformer industry, which must be more stringent for the quality of transformer insulating oil. Therefore, the supporting high-quality transformer insulating oil also needs to be quickly upgraded in order to keep up with the development of the power industry. Synthetic ester transformer insulating oil is a compound product of acid and alcohol. 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 type transformer oil. 1. Improve security Synthetic ester transformer insulating oil can be mixed with any other oil under different circumstances, such as mineral oil, it can better protect the environment and residents' safety, its excellent anti-oxidation properties, and its viscosity is more stable under high temperature conditions , better fluidity and better heat dissipation. 2. High flash point Synthetic ester transformer insulating oils offer an alternative to flame retardant fluids compared to mineral oils. The ignition point of synthetic ester transformer insulating oil is 300 ℃, while the mineral oil is 170 ℃. Synthetic ester transformer insulating oil has higher fire safety, so it can be used in more occasions, such as in urban buildings. The overall safety of the building can be enhanced. The application and development of synthetic ester insulating oil can greatly reduce the fire risk of transformers, and at the same time, the required area of the building can also be 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 damage the environment or cause pollution to water sources. Its environmental properties are unmatched by mineral oils. 4. Long-term 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 on 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, only a safety distance of 1.5 meters is required, which allows the land area and building area to be reduced. In urban construction, in order to reduce the required area for fire protection measures, synthetic ester oil-immersed transformers can be installed and used in underground spaces, saving a lot of cost and enhancing aesthetics. In addition, the high flash point of synthetic ester transformer insulating oil means that it can be used at higher temperatures, thereby increasing the capacity of the transformer without increasing its size. 6. Reduce installation and maintenance costs Reduce overhead by reducing auxiliary equipment such as fire protection systems, reducing maintenance costs and helping to reduce maintenance costs. In addition, research also shows that due to the excellent moisture resistance of synthetic ester transformer insulating oil, the service life of thermal insulation materials can be significantly prolonged, and its service life is increased by about 15% on average compared with mineral oil. 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 remains at 75kv, while even a very small amount of water in mineral oil will lead to breakdown voltage, rapid deterioration and problems. cause damage to the equipment transformer. 8. High temperature overload protection The high ignition point of synthetic ester transformer insulating oil enables it to withstand more than 20% overload, thus prolonging the running time of the transformer and improving the efficiency of the energy system. In addition, high temperature rise transformers can be designed for special applications, and the low flash point properties of mineral oils mean that high temperature operation is relatively less reliable than synthetic grease insulating oils. 9. Reliable products for future power transmission and transformation A major consideration for future urban development is whether existing infrastructure can be improved using new solutions without causing blackouts or disruptions. One of the main benefits of using synthetic or natural ester type transformer oils is that they can retrofit existing mineral oil transformers, allowing the transmission and distribution network to be retrofitted to meet new demands without any major modifications. The energy consumed by cities currently accounts for 70% of global energy, and is growing, which means that safer and more sustainable power transmission equipment and systems are needed. Adding synthetic ester transformer insulating oil to transformers can not only protect the surrounding environment, but also protect the environment. It can reduce maintenance and installation expenses and improve the efficiency of power distribution and transmission. In order to produce high-quality transformer oil and electrical insulating oil products that are energy-saving, environmentally friendly, and have high safety performance, Shuangjiang Energy uses industry-university-research cooperation projects as a link to introduce innovative talents, overcome technical bottlenecks, and develop technologies for processes, materials and key indicators. Research, focus on solving the technical problems of insulating oil oxidation stability, production and refining process, etc., improve various technical indicators, and make the overall technology reach the domestic and world leading level.
