Overview

The ZGF-40kV/4mA DC high voltage generator is a new generation portable DC high voltage generator redesigned and manufactured according to the requirements of the Chinese industry standard ZBF24003-90 "General Technical Conditions for Portable DC High Voltage Generators".

Product Details

1、 Product Introduction:

The ZGF series DC high voltage generator adopts new technologies, materials, and devices from the 1990s, with the characteristics of high output power, small size, and light weight. It has reliable overvoltage, overcurrent, and zero position closing protection functions, with a 0.75 times voltage latch function, and is equipped with a time relay, which can set timed sound alarms during testing. The entire instrument is portable, easy to operate, safe and reliable, especially suitable for on-site testing in the power sector.

The ZGF-40kV/4mA DC high voltage generator is suitable for conducting DC high voltage tests and leakage current tests on equipment such as zinc oxide lightning arresters, power cables, generators, transformers, and switches in the power sector and enterprise power departments.

3、 Product Features:

1. The ZGF-40kV/4mA DC high voltage generator is smaller in size compared to similar products. It is not only beautiful, reliable, and fully functional, but also lighter in weight, easy to operate, and fully functional. It can also be used in the field.
2. ZGF-40kV/4mA DC high voltage generator has high precision and accurate measurement. The voltage and current meters are both digital displays with a voltage resolution of 0.1kV and a current resolution of 1uA. The voltage meter on the control box directly displays the voltage value applied to the load test sample without the need for an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends for measuring leakage current, and the high voltage end is displayed with a circular shielded digital meter, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.
3. The ZGF-40kV/4mA DC high voltage generator has added the function of high-precision 75% VDC-1mA, which brings great convenience to the measurement of zinc oxide lightning arrester. A gentle press does not require calculation. There is a 75% voltage function key on the control box of this instrument. When conducting lightning arrester tests, when the current rises to 1000uA, press the 0.75UDC-1mA button. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, immediately return the voltage regulator potentiometer to zero and press the green button to cut off the high voltage and turn off the power switch before conducting other tests.
4. The convenient overvoltage setting function adopts a digital dial switch, which can intuitively display the set voltage value, making your operation more flexible. The displayed value is in kV.
