1、 Product Overview:

The series resonance withstand voltage equipment adopts the method of adjusting and controlling the frequency of the power supply to achieve series resonance between the reactor and the capacitor of the test object, generating high voltage and small current on the test object. This is a new method and trend in high-voltage testing for power detection, which has been widely applied and recognized at home and abroad.

The series resonance withstand voltage equipment is suitable for various occasions that require AC withstand voltage. It can meet the withstand voltage requirements of high voltage and large capacity products as well as small capacity and high voltage.

Reference standard: GB50150DL/T 474.4-2006 DL/T 596-2005 DL/T849.6-2004.

The series resonance withstand voltage equipment adopts a dedicated broadband voltage regulation power supply with a voltage regulation range of AC0-400V and a frequency modulation range of 30-300Hz. The frequency fineness can reach 0.1Hz, and the output waveform is good throughout the entire frequency range; Ensure instrument stability and safety with small weight and volume. The device consists of a frequency and voltage regulating power supply, an excitation transformer, a reactor, and a capacitive voltage divider.

2、 Product features:

The requirement for the capacity of the test power supply is small, only 1/Q of the traditional power frequency withstand voltage capacity is needed, with Q ≥ 30. Multiple power supply methods facilitate on-site access to electricity;

High reliability and good stability. The core components adopt imported components for stable voltage and frequency output, electromagnetic compatibility design, reasonable protection functions, and are fully applicable to different occasions;

Intelligent frequency conversion tuning can automatically tune and scan the resonant frequency, or manually search for it. When the system performs automatic scanning, it automatically scans from 30Hz to 300Hz. After completing the frequency scanning, the system preliminarily finds the resonant frequency point within its ± 5Hz range and performs a frequency fine scan with a resolution of 0.01Hz to accurately lock the resonant frequency;

Finding the resonant frequency device of the system allows for automatic boosting and completion of the test according to pre-set segmented or single test, and recording of the test results. It is also possible to manually adjust the voltage for withstand voltage testing;

When the test sample is punctured, the disappearance of high voltage due to system detuning causes minimal damage to the test sample;

The protection function is complete. Having zero position protection, overvoltage protection, overcurrent protection, flashover protection and other functions ensures the reliability of the system;

Flexible configuration and selection of different combinations of reactors can meet different testing requirements.
