摘要

河北省南部电网20%的发电机组存在抗燃油电阻率超标问题。根据多年试验研究

指出其电阻率超标主要原因为:(1)购置新抗燃油时检测不严;(2)抗燃油被极性物质污染;(3)运行中油温控制不当或系统中存在局部过热点;(4)抗燃油水分含量高。对此

提出了解决问题的办法及相应的防范措施。

Abstract

In southern power grid of Hebei Province

20% of turbo-generator sets have problem of fire-resistant oil's resistivity surpassing standard in operation.Based on test study in many years

the main causes of resistivity surpassing set standard have been pointed out as follows:(1)unstrict supervision in buying new fire-resistant oil;(2)the fire-resistant oil being polluted by polarized matters;(3)oil temperature in operation was not properly controlled

or partial overtemperature points existing in the system;(4)high water content in the fire-resistant oil.For this

the methods for solving said problems and corresponding countermeasures have been put forward.
