High-performance power cable fault distance finder The most advanced cable fault distance finder in China at present, adopts advanced embedded operating system, large-screen LED color LCD, high-speed acquisition chip, and the sampling frequency can reach 200MHz; innovative scale design concept And the question in the picture: High-performance power cable fault distance finder Answer: At present, the most advanced cable fault distance finder in China adopts advanced embedded operating system, large-screen LED color LCD, high-speed acquisition chip, and the sampling frequency can reach 200MHz; innovative ruler design concept and picture-in-picture split-screen display. The performance of the whole instrument is excellent, and the operation interface is very friendly. The following is a brief introduction: Power cable fault distance finder-1. The entire operating system adopts an advanced embedded operating system, which has the following characteristics:·The design adopts the structure design of embedded operating system Wince 6.0+ARM9, stable software design, and higher processing speed.
·Dedicated software management platform to complete software upgrade, backup, restore and other functions. 2. It has advanced multiple pulse testing methods, as well as low-voltage pulse testing and multiple pulse testing methods. Multiple pulse test, low voltage pulse test, pulse current test 3. Using the most advanced high-speed acquisition chip, the highest real-time sampling is 200MHz.
Especially in the pulse current mode, the sampling frequency can also reach 100MHz.·The highest sampling frequency of similar instruments in China is in line with the highest international level.·Provides a ranging resolution of up to 0.4m, with a small measurement blind area, especially effective for near-end faults and short cables.
4. The new LED large-screen color liquid crystal display is adopted. Because the LED liquid crystal has high brightness and large vision, it overcomes the problem that the displayed information is not easy to see when the ordinary liquid crystal is used in the field. The JCD-971 power cable fault distance finder adopts a high-brightness 8-inch large-screen LED color LCD with a viewing angle of up to 160°5. Ruler function·Visually display the basic situation of the cable, you can set 1 starting point, 10 contacts, 1 fault, and 1 full length.·The screen displays the ruler and the test waveform at the same time, which makes analyzing the cable waveform more intuitive and easier to understand.
6. Picture-in-picture temporary storage display function, the interface display adopts the picture-in-picture method, which consists of a main window and four temporary storage windows. Four temporary storage waveforms can be viewed at the same time, which makes the waveform comparison function more simple, intuitive and convenient. The figure below shows the comparison of the pulse current test waveform and the low voltage pulse test waveform.
