Abstract

Mineral oils play - in combination with cellulose (paper and pressboard), a vital part in the insulation system of large transformers and bushings. The dielectric stress within such insulation systems during high voltage direct current (HVDC) network operation is defined by a mixed stress that consists of AC, DC and transient components. Exemplary, the valve winding of converter transformers is to be named here.

电绝缘油的导电性测量
矿物油与纤维素(纸和纸板)结合在一起,在大型变压器和套管的绝缘系统中起着至关重要的作用。在高压直流(HVDC)网络运行期间,这种绝缘系统中的介电应力由交流、直流和瞬态分量组成的混合应力定义。举例来说,换流变压器的阀绕组在此命名。
