Product Specification

Portable DC Hipot Test Set , High Voltage Measurement Equipment , Hipot Test Equipment

I. Product Description

The test set is mainly composed of control box, cylinder type HV booster , fully shielded microammeter and DC discharge rod. The control box is used for control the test process and display test data , the cylinder type HV booster is to output DC high voltage , the fully shielded microammeter is for accurate display of leakage current and transfer the data to the control box.

Newly researched, designed, and manufactured according to  Common technical condition for portable DC HV generator of China Industry Standard, the ZGF series DC hipot test set is a technology product of new era, suitable for DC high voltage test and leakage current measurement on zin oxide arrester ,magnetic blow-out arrester, power cable, power motor or generator, transformer, and switch in electric power department, scientific research unit, railway station, power plant, chemical plant and so on.

Major parts of ZGF series high frequency DC high voltage generator adopt components made in America, Germany, Japan and so on with advanced technology, making equipment more reliable, more stable. Multi-voltage tube is developed and produced with German technology. With the features of small size, large capacity, strong overload capacity, and easy field operation test, high frequency transformer specially is designed by experts. Looking ahead, the company will continue to actively develop the market, take quality and credibility as its life, constantly improve its technology, develop a sophisticated quality products to meet the needs of users, and strive to open up and recast a new century glory.

II. Product features

1. DC HV generator is widely applied in the DC HV tests carried out for the zinc oxide lightening arrester, magnetic blow-out arrester, power cable, generator, transformer, circuit breaker, etc.
2. HZZGF-Z intelligent series of DC HV generator has the following main technical characteristics and functions:
3. Use large touch LED screen with human-machine dialogue function;
4. Full-automatic MOA voltage rise measuring function: good repeatability, high accuracy;
5. Automatic voltage rising function: With preset test voltage, the output voltage can be maintained constant;
6. Automatic timing function: Preset the voltage rising time of the standard test voltage, after rising to the standard test voltage, the timing will start automatically, when the timing is completed the voltage will drop automatically;
7. The HV over-voltage setting uses micro-processor for setting, which is highly precise and highly reliable;
8. Preserve the manual test mode;
9. Data storage function: Being able to timely catch the test parameters and automatically preserve the test results;
10. Based on the electromagnetic compatibility theory, use the special shielding, multi-level isolation and grounding and various other protection strategies to form a organized protection combination, during discharging under rated voltage the equipment will not be damaged;
11. ZGF totally intelligent series of DC HV tester possesses the online operation function with built-in online control software. The host computer (such as being equipped with PC) is installed with control software and auxiliary communication cable (optional) which can realize the online control.

III. Test circuit connection figure

Note : The control box(cabinet) is used for control the test process and display test data , the cylinder type HV booster(HV generator) is to output DC high voltage , the fully shielded microammeter(uA) is for accurate display of leakage current and transfer the data to the control box.

the discharge rod is for earthing grounding and discharge after finish DC test.
