DBJF-2020 intelligent partial discharge detector

Reference Standard: DL / T849.6-2004 Introduction DBJF-2020 intelligent partial discharge detector is the latest generation of digital-to-market of intelligent instrument, which in the original product DBJF-2002, DBJF-2006 PD meter based on ARM embedded system using a central processing unit, control 12-bit resolution analog to digital converter chip for high-speed data acquisition, the collected data is stored in the dual-port RAM. Achieve leap from analog to digital. Use a high-resolution 26 million color TFT-LCD module in real-time digital LCD display discharge pulse waveform with a VGA interface, external monitor, waveform analysis can be locked, automatically generated test report prints. Product Features 1. Color monitors, color display waveforms, more clear and intuitive; 2. Lockable waveform, easier carefully review the discharge waveform detail; 3. Automatically measure and display frequency test power base, without having to manually switch; 4. Equipped with a VGA interface to an external large-size display; 5. Equipped with micro-printer, can print directly generate test reports; 6. Compared with CRT live longer. Capacitance range of technical parameters l, detection of the product: 6PF a 250uF 2, the detection sensitivity "0.02pc (capacitor 50pf) 3. When scanning oval base: 50HZ and any frequency (and test power direct synchronization) 4, ellipse rotated 30 ° for a file, can be rotated 360 ° for 5, amplifiers: 3db low end frequency fL: lOKHZ, 20KHZ, 40KHZ, optional ;-end: 80KHZ, 200KHZ, 300KHZ optional. Gain adjustment range> 120db. Gain difference between stall 20 ± ldb, positive and negative impulse response asymmetry
