Description

technical field [0001] The present application relates to the field of oil-paper insulation experimental equipment, in particular to a visual oil-paper insulation electrothermal combined aging device based on magnon stirring cycle. Background technique [0002] As one of the key equipment in the DC transmission system, the converter transformer can realize electrical isolation and energy conversion between AC and DC sides. Different from the traditional power transformer, the converter transformer not only bears the superposition of electrical stress from the AC and DC sides during operation, but also suffers from the impact of DC full-voltage start-up and polarity reversal. The electric field is very severe under operating conditions. Equipment insulation is required to have sufficient dielectric strength and safety margin. Oil-paper insulation has good heat resistance, high mechanical strength, and excellent electrical properties. It is widely used in power equipment, esp...
