WXTF Variable Frequency Cable Resonant Test Set
Belongs to category： Series Resonant Voltage Withstand Device
Product Introduction
WXTF makes the reactor and tested capacitor in resonant by adjusting the frequency of the power source, to get high voltage and heavy current from measured equipment. Now it is a new method and trend for high voltage test and widely used.
WXTF uses special SPWM digital wave-generate chip, resolution is 16 bits, the frequency adjustment fineness could be 0.1Hz if the frequency was 20~300Hz; adopts sine asynchronous fixed wave carrier modulation, to ensure the waveform output is good in the whole frequency range; adopts advanced IPM module, ensure the stability and safety of the device under minimum weight.
Application
◆The AC withstand voltage test device is suitable for AC withstand voltage test of transformers, circuit breakers, switches, GIS systems, cables, bushings, insulators and other equipment. With high voltage overvoltage protection, low voltage overcurrent protection, as well as detuning protection, zero position, flashover protection, emergency shutdown, undervoltage protection and other multiple protection functions. It can meet the test requirements of high voltage and low current equipment, and meet the test requirements of low voltage and high current equipment. It has a wide range of application.
◆The frequency adjustment of the AC withstand voltage test device is divided into coarse adjustment and fine adjustment, and the test resonance point can be automatically found to ensure that the resonance frequency does not drift during the whole test process; the required power supply capacity is small, and the power supply required for the test is only tested. The capacity is 1/Q; the volume is small and the weight is light, which is 1/3-1/5 of the common test device; the resonant power supply is a resonant filter circuit, which can improve the waveform distortion of the output voltage and obtain a good sinusoidal waveform, effectively preventing Harmonic peak to the wrong breakdown of the test sample; with a variety of working modes, 220V or 380V single-phase power supply, convenient on-site power; multi-mode, modular combination, can be combined and easy to operate, convenient for on-site use.
Product Characteristics
◆1.Small in volume, light in weight.
◆2.This system need one person to carry the device less than 30KG, two people less than 60KG. Suitable to carry on site.
◆3.Power supply, Single phase: 220V or 380V, convenient to get power on site.
◆4.Reactor uses epoxy cast, beautiful and reliable, suit for all kinds of cables.
◆5.110kV and above voltage level cable withstand voltage test use oil-immersed reactors, when the weight of single machine is more than 100kg, optional dedicated small electric cranes.
