Product details
1、 Product Overview:
The HZBP-DL series cable specific frequency conversion series resonant withstand voltage device adopts the method of adjusting and controlling the power supply frequency to achieve series resonance between the reactor and the tested capacitor, generating high voltage and small current on the tested sample. This is a new method and trend in high-voltage testing that has been widely applied and recognized at home and abroad.
The HZBP-DL series variable frequency series resonant withstand voltage device adopts a dedicated broadband voltage regulation power supply with a voltage regulation range of AC0-400V and a frequency modulation range of 20-300Hz. The frequency fineness can reach 0.1Hz, and the output waveform is good throughout the entire frequency range; Ensure instrument stability and safety with minimal weight and volume. The HZBP-DL series frequency conversion resonant withstand voltage device consists of a frequency modulation and voltage regulation power supply, an excitation transformer, a reactor, and a capacitive voltage divider.
