Description
Technical Field
The utility model relates to an electric power tech field, in particular to medium response analytical equipment.
Background
For high voltage equipment, such as power transformers, circuit breakers, disconnectors, current transformers, voltage transformers, rotating electrical machines and cables, the insulation system is subjected to various stresses throughout its lifetime, including high temperatures, vibrations, electrical fields and exposure to moisture, oxidation, acid corrosion and other chemical contaminants. As a result, its mechanical and electrical properties gradually deteriorate and ultimately affect the reliability of the device. The performance degradation process is mainly a chemical and physical process, and the degradation speed is greatly influenced by heat, oxidation and a humid environment. Moisture has a particularly large influence on solid insulating materials such as paper and the like, and is also an index of the aging degree.
The insulating structure of a high voltage device can be represented by a dielectric model consisting of series and parallel connected resistors and capacitors representing polarization and conductance losses in the insulating material. The dielectric response is a unique characteristic for any particular insulation system. The increase in moisture content in insulation causes a change in dielectric strength and thus a change in dielectric response characteristics. However, the existing insulation aging detection means of the high-voltage equipment can only be carried out in a narrow frequency range, and the measurement accuracy of the dielectric response measurement analysis carried out on the insulation of the high-voltage equipment is not high.
