Description

KGXZ-A Cable Series Resonance Tester

Product Introduction
KGXZ-A cable frequency conversion series resonance test device adopts the mode of adjusting the frequency of the power supply, so that the reactor and the tested capacitor achieve resonance, and obtain high voltage and high current on the tested product, which is a new method and trend of high voltage test at present, and has been widely used at home and abroad.
KGXZ-A cable frequency conversion series resonance test device is composed of frequency regulating voltage power supply, excitation transformer, reactor and capacitance divider.
KGXZ-A cable frequency conversion series resonance test device adopts special SPWM digital waveform generator chip, frequency resolution is 16 bits, the frequency fineness can reach 0.1Hz when 20 ~ 300Hz; Orthogonal non-synchronous fixed carrier modulation is adopted to ensure good output waveform in the whole frequency range. The power part uses an advanced IPM module to ensure the stability and safety of the instrument at minimum weight.

Product Characteristics
1. The number of cables of 35kV and below voltage levels is large, and the test workload is large, so this kind of voltage test device is small in size and light in weight, and the portable cable voltage test system is born from this;
2, the system requires that a single person can move the parts of the site weight does not exceed 30kg, requires two people can move the parts of the site weight does not exceed 60kg, suitable for on-site handling;
3, the power supply adopts 220V single-phase power supply or 380V single power supply, which is convenient for on-site power collection;
4, the reactor part adopts dry epoxy casting, beautiful and reliable, suitable for all kinds of cable requirements;
5, 110kV and above voltage grade cable withstand voltage test using oil-immersed reactor, in the weight of more than 100kg, can be selected for our company’s special small electric crane.
