Frequency Conversion Series Resonance Tester - Suitable for Inductive Withstand Voltage Test of Power Transformer
Frequency conversion series resonant test equipment Transformers, GIS systems, SF6 switches, CT/PT, insulators, busbars, cables, casing and other capacitive devices are the most common primary electrical equipment in substations. According to the 220V and the following substation electrical equipment withstand voltage test procedure requirements, the corresponding AC / DC current resistance test equipment must meet the high voltage, low current test conditions, but also to meet the low voltage, high current test conditions, requirements and take into account The wider scope of application, the principle of series resonance, by the variable frequency power supply control box (operating console), incentive transformers, reactors, capacitive voltage divider composed of the main equipment, in the capacitive voltage divider, access to rectifier silicon reactor and Micro-ampere meter can complete DC withstand voltage test. Because the system has good filter characteristics after resonance, so its production of DC voltage is better than the original test transformer rectification of the initial DC voltage. It is an ideal pressure-proof equipment for high-voltage test departments at the local, city and county levels, as well as power installation and repair engineering units.
The frequency conversion series resonance test equipment uses the principle of series resonance, uses the excitation transformer to excite the series resonant circuit, and adjusts the output frequency of the inverter controller so that the reactor inductance L in the loop and the sample capacitor C generate series resonance, and the resonant voltage is tested. The voltage applied to the product. The frequency conversion resonance test device is widely used in electric power, metallurgy, petroleum, chemical industry and other industries, and is suitable for the transfer and preventive testing of large-capacity, high-voltage capacitive test products;
