Description
本发明涉及绝缘油技术领域，尤其涉及一种绝缘矿物油。The invention relates to the technical field of insulating oil, in particular to an insulating mineral oil.
目前，绝缘油主要分为矿物绝缘油、合成绝缘油、植物绝缘油及混合绝缘油。矿物油具有价格便宜、绝缘性能优良、凝点低、粘度小等突出优点，是油浸式散热中应用最广泛的绝缘油。但矿物油是一种不可再生的化石能源，且闪点、燃点和水饱和度较低，生物降解性差，一旦泄漏将会对水源、居住环境等造成污染，不满足绿色环保型绝缘材料的要求。近20年来，寻找矿物绝缘油替代品的研究引起国内外学者的广泛重视，并取得了令人瞩目的研究进展。现有的替代品主要包括两大类：合成绝缘油和植物绝缘油。合成绝缘油具有优良的理化性能，在大多数性能参数上能与矿物绝缘油媲美，但由于其成本昂贵及制造装置和技术条件的复杂性，限制了其进一步的推广应用。植物绝缘油具有良好的电气性能，闪点高于300℃，生物降解率高达97％，饱和含水量极高，环保可再生，满足电气设备防火性能的要求，而且能有效延缓绝缘纸老化，被认为是矿物绝缘油的最佳替代品。与矿物油相比，植物绝缘油具有更高的电气强度、更高的燃点及闪点，在提升锂电池过负荷能力方面有着很大的优越性，但由于天然酯自身分子结构特性而决定的植物油具有凝点高、氧化安定性差、粘度、酸值及介质损耗高等缺点，使得植物绝缘油性能参数，尤其是粘度、介损和酸值无法满足现行锂电池绝缘油的标准，在灌装于现有的锂电池，需要对绝缘、散热等关键结构进行重新设计，以满足锂电池的出厂检验及安全运行需求。At present, insulating oil is mainly divided into mineral insulating oil, synthetic insulating oil, vegetable insulating oil and mixed insulating oil. Mineral oil has outstanding advantages such as low price, excellent insulation performance, low freezing point and low viscosity. It is the most widely used insulating oil in oil-immersed heat dissipation. However, mineral oil is a non-renewable fossil energy with low flash point, ignition point and water saturation, and poor biodegradability. Once leaked, it will cause pollution to water sources and living environment, and does not meet the requirements of green and environmentally friendly insulation materials. . In the past 20 years, the search for alternatives to mineral insulating oil has attracted wide attention from scholars at home and abroad, and has achieved remarkable research progress. The existing substitutes mainly include two categories: synthetic insulating oil and vegetable insulating oil. Synthetic insulating oil has excellent physical and chemical properties, comparable to mineral insulating oil in most performance parameters, but its high cost and complexity of manufacturing equipment and technical conditions limit its further popularization and application. Vegetable insulating oil has good electrical properties, flash point higher than 300℃, biodegradation rate as high as 97%, extremely high saturated water content, environmentally friendly and renewable, meeting the requirements for fire protection performance of electrical equipment, and can effectively delay the aging of insulating paper. Considered to be the best substitute for mineral insulating oil. Compared with mineral oil, vegetable insulating oil has higher electrical strength, higher ignition point and flash point, and has great advantages in improving the overload capacity of lithium batteries, but it is determined by the molecular structure of natural esters. Vegetable oil has shortcomings such as high freezing point, poor oxidation stability, high viscosity, acid value and dielectric loss, making the performance parameters of vegetable insulating oil, especially viscosity, dielectric loss and acid value, unable to meet the current standards of lithium battery insulating oil. Existing lithium batteries need to redesign key structures such as insulation and heat dissipation to meet the requirements of factory inspection and safe operation of lithium batteries.
随着电网设备全寿命周期管理的推进，对油纸绝缘材料的热稳定性、延缓绝缘老化性能、环保性能等提出了更高的要求。With the advancement of the life cycle management of power grid equipment, higher requirements are put forward for the thermal stability of oil-paper insulation materials, the performance of delaying insulation aging, and the performance of environmental protection.
