Abstract

The embodiment of the invention relates to a high-voltage signal source, dielectric response test equipment, a test system and a test method, and the high-voltage signal source comprises a clock generation module which is used for generating a clock signal; a frequency synthesis module which is connected with the clock generation module and used for generating a first low-voltage signal according to the clock frequency of the clock signal, wherein the range of the output frequency of the first low-voltage signal corresponds to the clock frequency; a signal conditioning module which is connected with the frequency synthesis module and is used for filtering the first low-voltage signal to generate a second low-voltage signal; and a voltage amplification module which is connected with the signal conditioning module and is used for amplifying the amplitude of the second low-voltage signal so as to generate a high-voltage signal. The high-voltage signal source can output low-frequency periodic high-voltage signals, the efficiency and accuracy of dielectric response characteristic testing of oiled paper can be effectively improved based on the signals, support of other assemblies is not needed, and therefore follow-up circuit cost is reduced, and instrument space is saved.

Description

technical field [0001] The embodiments of the present application relate to the field of measurement technology, and in particular to a high-voltage signal source, dielectric response testing equipment, testing system and testing method. Background technique [0002] With the rapid and stable development of my country's national economy and the rapid growth of people's demand for electric energy, the scale of my country's power grid is expanding day by day. While the power system is developing in the direction of ultra-high voltage, large capacity, large power grid, and automation, it is more important to improve the reliability and stability of power equipment operation. In the operation of the power system, oil-immersed transformers are widely used in high-voltage and ultra-high-voltage transmission systems and electrified railway traction power supply systems due to their high dielectric strength and long service life. They are responsible for voltage conversion, power di...
