变压器油起填充和浸渍的作用,

变压器油绝缘强度高,在电气设备中主要作绝缘介质使用,又因比热容较大,故也作冷却介质,在断路器和有载分接开关及起动补偿器中作熄弧介质使用和起冷却触头作用。
Transformer insulating oil dielectric strength is high, mainly for use in electrical equipment, and therefore heat capacity is large, so it is used as cooling medium, in circuit breaker and load switch and starting compensator for the cooling effect of arc extinguishing medium and contact.
纯净的变压器油的电气强度达200一250kV/cm,比空气高4-7倍。 因此用变压器油作绝缘可大大缩小变压器的体积。由于纸和纸板的原料很丰富、价格较便宜、机械强度尚好,浸变压器油后电气强度高,当变压器油被击穿以后,绝缘可以恢复,不会留下永久性的放电通道,因此变压器油得到了广泛的应用。
The electric strength of the pure transformer oil is 200 250kV/cm, 4-7 times higher than that of the air. Therefore, the use of transformer oil as insulation can greatly reduce the volume of the transformer. The paper and paperboard material is very rich, the price is cheaper, the mechanical strength is good, oil immersed transformers after high electrical strength, when the transformer oil breakdown after insulation can be restored, will not leave the discharge channel permanent, so the transformer oil has been widely used.

在高压电缆中,变压器油起填充、浸渍的作用,以清除电缆内部的气体,提高电气强度。在油浸纸介电容器中,油起填充、浸溃、绝缘的作用,以提高电容量和绝缘强度。
In high voltage cables, the transformer oil plays the role of filling and impregnating to remove the gas inside the cable and improve the electrical strength. In oil immersed capacitor, oil filling, impregnation, insulation, in order to improve the capacitance and dielectric strength.
由于灭弧强度主要取决于油气分解产生的油气混合物。这种油耐压降低不会显著降低其灭弧能力,故少油断路器的油要求可以比变压器中所用油的要求低些。
The intensity of arc extinguishing mainly depends on the mixture of oil and gas produced by the decomposition of oil and gas. This oil pressure reduction will not significantly reduce its arc extinguishing capability, so the oil requirements of the oil - less circuit breaker can be lower than the requirements of the oil used in the transformer.
