交直流复合电场下油纸绝缘的电场特性
Converter transformer is an essential component in high voltage direct current (HVDC) power transmission system. Comparing to ordinary AC power transformers, the valve winding on the converter transformer withstands combined AC and DC voltage in operation. Different locations and different connection shapes result in different ratio of the AC/DC voltages, and thus different field distribution around each valve windings. Adopting the Ken-electro-optic method, the present research established a two dimensional oil-pressboard electric field measurement platform. According to the real operation situations of the valve windings, the field distribution of the oil-pressboard insulation under different ratios of the AC/DC voltage application was measured and analyzed.
