摘　　要：根据电桥平衡原理,将绝缘纸做成电容器试样,通过测量被测试样的电容量换算出绝缘纸的介电系数ε,对比分析了不同温度下绝缘纸和打印纸的介电系数ε和损耗角正切tanδ,结果表明在相同条件下绝缘纸比打印纸具有更好的绝缘性、耐热性和低损耗特性.According to equilibrium principle of electric bridge, insulating paper and normal printing paper had been made into a capacitor. By measuring capacitance of the capacitor, relationship between their dielectric constant and dielectric loss factor with ambient temperature was studied carefully. The results showed that insulating paper had better insulation and heat proof,and lower dissipation than normal printing paper under the same conditions.
