HY-CDS Special Equipment For Capacitor Charging And Discharging

Product manual download：HY-CDS

HY-CDS series capacitor charging and discharging specialized equipment is applied to capacitor manufacturers, capacitor users, and capacitor testing and measurement units, and can perform dv/dt testing.

The method is to first charge the tested capacitor and measure the dv/dt value during the rapid discharge process of the capacitor. The signal voltage, frequency, and discharge resistance can be set as needed. The signal is applied to both ends of the tested capacitor, the test cycle is set, and the capacitor is continuously tested. During the test, the temperature rise, capacity, and loss of the capacitor are continuously monitored and recorded. Finally, evaluate whether the capacitor meets the requirements based on its temperature rise and changes in capacity and loss.

By using this method for detection, whether it is the characteristics of the material (polarization characteristics), or the differences in structural design (electrode resistance) and losses, they can be intuitively reflected through the temperature rise and capacity loss changes of the capacitor.

Features

■ Input voltage: 220VAC50HZ

■ Output voltage: 100~2000V continuously adjustable (customizable)

■ Charging and discharging test current: 0-3000A (customized)

■ It is necessary to detect the actual voltage on the tested product and display it (at a frequency of 1kHz, the average value of the charging voltage is taken every 10 times and displayed; the trigger time of the machine is about 300mS) to determine whether the product is fully charged; If there is no voltage, an alarm signal should be output;

■ Trigger mode can be manually and automatically switched; How long should it be triggered and how long should the device operate continuously.

■ Charging and discharging frequency: 0.5k/1kHz (customized)

■ Discharge resistance: 0 Ω

■ Test capacitance: 1nF~110uF (customized)
