1、 Product Introduction:
ZGF-200kV/5mAThe DC high-voltage generator is based on Chinese industry standardsZBF 24003 – 90According to the requirements of the "General Technical Conditions for Portable DC High Voltage Generators", a new generation of portable DC high voltage generators has been redesigned and manufactured. This 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.
2、 Product features:
1TheZGF-HDC high-voltage generators are smaller in size, not only beautiful, reliable, and fully functional compared to similar products, but also lighter in weight, easier to operate, fully functional, and can be used in the field.
2High precision and accurate measurement. The voltage and current meters are both digital displays, with a voltage resolution of0.1kVThe current resolution is1uAThe voltmeter 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.
3The 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 unit iskV.
4Added high precision75%VDC-1mAThe function of zinc oxide lightning arrester measurement brings great convenience. A gentle press does not require calculation. There are on the control box of this instrument75%The voltage function key, when conducting lightning arrester tests, when the current rises to1000uAPress and hold0.75UDC-- 1mAThe button displays the values on the voltmeter and ammeter75%After completing the data, the voltage regulator potentiometer should be immediately returned to zero position, and the green button should be pressed immediately to cut off the high voltage and turn off the power switch. Conduct other experiments.
