Product Introduction
Yangzhou Topu Electric Technology Co., Ltd. specializes in producing the Topu brand75KVA/75KV/1ATechnical parameters of the complete set of frequency conversion series resonance test equipmentWidely used in industries such as power, metallurgy, petroleum, chemical, etc., suitable for high-capacity and high-voltage capacitive test samples, such as generators, transformers, etc GIS、 Handover and preventive tests for high-voltage cross-linked cables, transformers, bushings, etc. Yangzhou Topu Electric Technology Co., Ltd. has independently developed frequency conversion and voltage regulation software technology in the field of frequency conversion series resonance high voltage testing, which is superior to the domestic high voltage testing industry. Using this technology, a complete set of frequency conversion series parallel resonance testing equipment is designed and manufactured using 16 bit fine frequency conversion, 10KHz carrier frequency, SPWM, and imported IPM integrated modules, which complies with relevant regulations and requirements for high voltage testing.

working principle
The variable frequency series resonance test device applies the principle of series parallel resonance. By adjusting the output frequency of the variable frequency controller, the inductance L of the reactor in the circuit and the capacitance C of the test sample resonate, and the resonant voltage is the voltage applied to the test sample. The power supply is provided through the frequency modulation controller, and the test voltage is initially boosted by the excitation transformer to apply high voltage to the reactor L and the test sample CX. By changing the output frequency of the frequency modulation controller, the circuit is in series resonance state; The resonant frequency of the circuit depends on the capacitance CX of the test sample and the inductance L of the reactor. Adjust the output voltage of the variable frequency controller to achieve the required voltage value of the high voltage on the test sample.
