Description

technical field [0001] The invention relates to the technical field of voltage testing of electric porcelain appliances, in particular to a voltage stability testing system for high and low voltage electric porcelain appliances. Background technique [0002] Electric porcelain is an electrical ceramic, which refers to a kind of porcelain electrical insulating material with good insulation and mechanical strength, such as insulators; electric porcelain is a component used in power systems that mainly supports and insulates, and sometimes serves as other electrical components container. Therefore, there are high requirements for its mechanical properties, electrical properties, and environmental resistance (hot and cold, anti-pollution, aging, etc.); [0003] The mechanical quality factor is an important parameter for evaluating material loss, but the electromechanical coupling parameters provided by piezoelectric component manufacturers are all parameters under the small sig...
