■ Product Overview

Vs-clxz series frequency conversion series resonance test device is mainly composed of frequency conversion controller, excitation transformer, high voltage reactor, high voltage divider, etc. The device is suitable for 10KV, 35KV, 110KV, 500KV power cable, GIS AC voltage test; Suitable for large transformer, generator group power frequency withstand voltage test and power transformer induction withstand voltage test.

■ Functional features

▲ Internal control by embedded touch screen, optimized operation function, simple operation.

▲ The device has three working modes, convenient for users to choose flexibly according to the site situation, improve the speed of the experiment.

▲ Working mode: automatic mode, manual mode, automatic tuning manual boost mode, automatic sweep, looking for resonance point, frequency range 20-300Hz, can manually set the sweep range, sweep time 1.5 minutes (full frequency sweep), frequency resolution 0.1Hz.

▲ Automatic test, users can set the test procedure, the system automatically according to the set procedure to complete the experiment process.

▲ Automatic test, automatic tracking system resonance state, when the resonance state changes, more than the set area, the system automatically tracking resonance point, in the whole process to ensure that the system works in a better output state, FM draw frequency voltage curve.

▲ When the voltage automatic tracking voltage, voltage normal fluctuation automatically adjust the voltage to the target voltage, by the user according to the test conditions for operation.

▲ Full voltage output protection: in the process of voltage regulation, strictly ensure that the inverter power supply will not be full voltage output.

▲ Software through strict simulation operation test, safe, stable and reliable operation.

▲ Automatic storage of test data, data query function, according to the query conditions query past experimental data.

▲ LCD display can display power supply voltage and current; The frequency, voltage, and current of the high voltage output.

▲ Protection function: with power, over current, over voltage machine flashover protection function.

▲ Over voltage protection: can be manually set over voltage protection value; When the output voltage of the whole device reaches the protection setting value, the whole device will be cut off automatically.

▲ Breakdown protection: with discharge or flashover protection function, when the high voltage side occurs to the ground flashover, automatically cut off the whole device. It will not cause damage to the test equipment and human body, and the electronic components in the frequency conversion power supply will not break down.

▲ Power protection: after the test power supply is off, the device can be quickly protected.

Bring device automatically when the frequency sweep frequency starting point can be set freely within the prescribed scope, square can sweep up and down to select, LCD screen display scanning curve at the same time, the convenient user intuitive understanding whether find resonance point, adopting the technology of DSP platform, can according to user needs to increase or decrease in function and upgrade, also makes more humanized human-computer interface exchange.

▲ Quality factor: the device itself Q≥30 (F =45Hz).

▲ Working time: continuous 60min under rated load.

▲ Temperature rise: continuous 60min under rated load.
