■ Product Overview
V - WCLXZ series series resonance test device is mainly used in partial discharge measurement of all kinds of insulation materials, insulation structure and the electrical power frequency voltage insulation products such as tolerance, the sample (s) as transformer, transformer, lightning arrester no electrician frequency partial discharge test of power supply, it is widely used in electrical manufacturing, electric power operation departments, scientific research units and institutions of higher learning. 50-2250 kv series resonance test device without bureau through the product identification, the ministry has no resonance can accurately detect partial discharge main transformer, transformer, GIS, cable, casing, such as arc suppression coil, the capacitor current request bureau's capacity test of some special subjects of internal insulation, internal insulation partial discharge of microcosmic reaction, predicting subjects to taste life, And eliminate hidden dangers from the source.
■ Functional features
▲ Variable frequency power supply has the ability to resist electric field interference. Under strong electric field interference, the measurement accuracy and control protection meet the requirements. With good magnetic shielding, components and leads are shielded by high magnetic conductivity materials, no space radiation.
▲ With perfect protection function input voltage protection, over voltage protection, short circuit (over current) protection, breakdown flashover protection, zero protection, power curve protection, power off protection, over temperature protection, cooling fan linkage protection, output voltage limit function protection.
▲ Frequency conversion power supply adopts the principle of high-fidelity linear power amplification, there is no high harmonic caused by IGBT switching circuit, to ensure complete sine wave output and very low electronic interference signal, to ensure very low local discharge (≤10pC).
▲ Frequency conversion power supply is equipped with special lead and plug to connect with other equipment and special grounding wire group.
▲ Intelligent display frequency conversion power control box.
