摘要

研究了氧碱(O-A)麻皮纤维电绝缘纸的热老化性能。热动应力作用后，红麻韧皮纤维的机械强度有所下降，但电学性能在整个过程中没有变化。无论是在空气中还是在变压器中，红麻纤维电绝缘纸和压板的热老化性能劣化率与NUKP电绝缘纸和压板相似。由于红麻韧皮纤维纸浆的这一特性的初始值较大，因此其老化后的绝对值也较大

The hot-ageing property of electric insulating paper and press board of O-A kenaf bast fibre

The hot-ageing of electrical insulating paper made of oxygen-alkali (O-A) kenaf bast fibre was investigated. After hot kinetic stress, the mechanical strength of the kenaf bast fibre decreases somewhat, but the electrical properties do not change throughout the whole process. Either in air or in a transformer, the kenaf bast fibre electric insulating paper and press board's deterioration rate of the hot-ageing property is similar to that of NUKP electric insulating paper and press board. Because the initial value of this property is greater for the kenaf bast fibre pulp, its absolute value after ageing is also greater.<>
