1、Simple operation: three modes: automatic tuning(finding resonance point automatically),automatic test(finding resonance point automatically and voltage boosting automatically)and manual test(finding resonance point manually and voltage boosting manually)
2、It can set the test voltage, frequency range, protection current and boosting time.
3、automatic mode: only need to set the test voltage and time; system regulate frequency and voltage automatically; complete the test and save the data
4、It has grounding and flashover protection functions.
5、It can automatically track the change of power grid voltage and adjust the voltage in real time to keep the high voltage stable.
6、Easy to operate: single phase 220v or three phase 380v input power supply is universal, convenient for on-site electricity.
7、Reactors with the same voltage grade and capacity are smaller in size and lighter in weight. small temperature rise at rated load; dry epoxy casting, high mechanical strength, good electrical insulation, beautiful and reliable.
8、Flexible configuration: the reactor can be used in series/parallel to meet the requirements of different test products, to achieve multi-purpose and cost-effective.
9、The large-screen touch LED LCD color screen and external mouse directly complete the setting of various parameters, and the test results can be saved, printed, uploaded and checked back.
10.The ZCVF-B cable ac voltage withstand series resonant testing system is composed of variable frequency power supply, excitation transformer, reactor and capacitor voltage divider. The capacitance and the reactor of the tested product constitute a series resonant connection mode. The voltage divider is connected in parallel on the test object to measure the resonant voltage on the test object and make the over-voltage protection signal. The frequency modulation power output is coupled to the series resonance circuit by the excitation transformer, providing the excitation power of series resonance.
11. ZCVF-B cable ac voltage withstand series resonant testing system adopts multi-stage superposition mode, multiple reactors can be used in parallel and series, the voltage divider is used to measure the test voltage, but also can be used as a small capacitance test of the compensation capacitance, so that the resonate frequency can be in the range of 30-300Hz to complete a variety of power equipment ac voltage withstand test. The basic principle of variable frequency series resonance is to generate ac test voltage by using adjustable(30-300Hz) series resonance test equipment and test object capacitor resonance.
