Low Price High Voltage Digital Partial Discharge Tester

I. Product Information:


Product Description:
HZJF-124 digital partial discharge detector is the newly development digital LCD partial discharge detector for solving the problem of low brightness and short service life of the traditional local discharge detector. It is wildly used in measurement of partial discharge of various HV electrical products such as transformer, mutual inductor, HV switch, switch cabinet, zinc oxide surge arrester, power cable etc.

Product  Features:
1.After digital processing,the partial discharge signal is displayed by liquid crystal.
2.Easy operation
3.With multiple display mode like ellipse,line,or sinusoidal.
4.Adopt digital windowing technique to avoid influence of interference to measurement.
5.Arbitrary phase windowing,with selection of single window and double window,ellipse rotating 150 degree.
6.The current discharge map can be stored,static observation and analysis to partial discharge pulse.
7.Can store the current discharge map.

X Ray Machine

The system matches with metal ceramic X-ray tube and high frequency solid insulate industrial X-ray HT generator, it applies forced cooling system to make sure X-ray machine can normally continuous work for 24 hours. The dimension of this kind of small focus X-ray tube is half of traditional focus tube, geometry unintelligibility is an important factor which affects image quality, if focus bigger, correspondingly, geometry unintelligibility is deeper, and also makes image edge much more blur; if focus smaller, geometry unintelligibility is lighter, it can improves image quality at same time, also focus is smaller can inspect smaller failure which is favor to improve X-ray RTR inspection stability.

The controlling part of system is researched and manufactured by ourselves, the intelligent main control PLC works matches with touch screen, beautiful and complete functional stainless steel panel that can display and adjust parameters much more convenient. When high voltage of system opens, there will be red light alarming signal outside of protect door, here installs interlock devices between lead door and system, in the case of opening lead door, system will stop radiation at once to assure safety of operators.
