Variable Frequency Series Resonant Test System

Product Overview

The Cable-Specific Portable Variable Frequency Resonant Step-Up Device is a specialized equipment designed for high-voltage testing on cables. By adjusting the power frequency, the device creates resonance between the reactor and the capacitor of the cable under test, thereby achieving the required high voltage and high current on the test item. This method has become the new trend in high-voltage testing and has been widely recognized and applied both domestically and internationally.

Variable frequency resonance step-up device utilizes a dedicatedSPWMDigital waveform generator chip with a frequency resolution up to16Positioned.20～300HzWithin the frequency range, the frequency resolution can reach0.1HzEnsured the integrity throughout the testing process.Please provide the Chinese content to be translated..Certainly.Sexual and stability. The device also employs an orthogonal asynchronous fixed-carrier modulation method, effectively ensuring excellent waveform quality throughout the frequency range, thus avoiding the impact of waveform distortion on the test results.

In the power section, the variable frequency resonant step-up device utilizes advancedIPMModule, a highly integrated and efficient power module, ensures excellent stability and safety for instruments at a low weight. This design not only makes the entire device more portable and convenient for on-site use, but also significantly enhances its reliability and lifespan.

The Variable Frequency Resonant Voltage Booster is mainly composed of a frequency-voltage regulating power supply, an excitation transformer, a reactor, and a capacitance voltage divider. These components work together to achieve high-voltage cable testing. The frequency-voltage regulating power supply is responsible for providing a stable power output and adjusting the frequency and voltage according to testing requirements. The excitation transformer is used to increase the source voltage to the required testing level. The reactor and capacitance voltage divider are used to form a resonant circuit with the tested cable, generating the required high voltage and large current.

In summary, the portable variable frequency resonance step-up device for cables is an efficient, stable, and reliable high-voltage cable testing equipment. It incorporates advanced technology and design concepts, capable of meeting various high-voltage cable testing requirements, and is an essential tool for power systems and cable manufacturers in cable testing and quality control.
