摘 要:利用第3代SY型便携式绝缘油耐压试验仪,测定在不同温度、水分和机械杂质下,绝缘油介电强度的变化。结果表明:温度的升高能使绝缘油的击穿电压增大,当温度达到一定的时候,击穿电压开始下滑;而油中水分、机械杂质的增多,会使油液击穿电压有较明显的下降,因此在绝缘油运行前应该注意防潮、去杂。The variety of dielectric strength of insulating oil in different temperature, moisture, mechanical impurities with the third generation withstand voltage tester of the portable type SY model was measured. The result indicated that as the temperature became higher, the dielectric strength of insulating oil became stronger, that when the temperature rose to certain degree, the dielectric strength of insulating oil became to slip, and that, however, as moisture and mechanical impurities in insulating oil became greater, the dielectric down obviously. So, attention should be paid to moisture prevention and impurities removal.
