I. Introduction DBM8000 ANI precision dielectric loss measuring instrument for field interference dielectric loss measurements, or laboratory precision measurement of dielectric loss. Instrument for the integration of structure, built dielectric loss bridge, power inverter, test transformer and standard capacitors. Using frequency interference and Fourier transform digital filtering technology, automatic intelligent measurement, strong interference measurements are very stable. Measurement results show that the large-screen LCD, comes with mini printer can print output. Second, the main features 1 frequency interference with frequency jamming technology, still precisely measured at 200 percent interference, test data stability, suitable for on-site tests do anti dielectric loss. 2 high-precision measurement with digital waveform analysis, and bridge self-calibration technology, with high-precision standard three-terminal capacitors, high-precision measurement of dielectric loss. All instrument scale input resistance is less than 2Ω, eliminating the influence of additional capacitance measuring cable. 3. Multi-level security, to ensure personal and equipment safety pressure protection: short circuit test, breakdown or high current fluctuations, can short-circuit the way high-speed cutting output. Low voltage protection: wrong connection 380V, power fluctuations or power outage, boot protection, does not cause over-voltage. Ground Protection: the instrument when the housing is poorly grounded with dangerous voltages start ground protection. CVT: High Voltage and current, low voltage and current limit of four protection, will not damage the equipment; mistakenly select menu does not output excitation voltage. No 10kV high voltage output CVT measurements. Prevent misuse: two power switch; voltage, current, real-time monitor; multi-press to confirm; Terminal high / low seasons; retarder boost, buck quickly, sound and light alarm. Anti "Yung L": there will be a voltage elevation "Yung up" effect when measuring large-capacity test, the instrument can automatically track the output voltage to maintain a constant test voltage. Seismic performance: The instrument uses a unique seismic design, can withstand strong long-distance transport vibration, bumps without damage. High voltage cables: for the high voltage insulated wire, can be used to drag. 4 powerful features, product serialization of the instrument belongs Model: E-type. (1) has a positive / negative wiring, internal / external standard capacitors, inner / outer high-pressure variety of operating modes, integrated structure, do a variety of conventional dielectric loss test, without any external auxiliary equipment. (2) liquid crystal display, menu operation, test data-rich, automatically distinguish capacitance, inductance, resistance-type test, comes with mini printer can print output. (3) has an external standard capacitor interface, external oil cups do precision insulating oil dielectric loss test, you can add a solid material to do precision measuring electrode insulation material dielectric loss test, also be an external high voltage standard capacitor dielectric loss do high-voltage test. (4) Automatic Identification 50Hz / 60Hz power supply system, and support for generator power, even if the frequency fluctuations, can also be normal measurements. (5) Built-in serial and parallel two kinds of dielectric loss measurement model, convenient instrument calibration. (6) can store 255 sets of measurement data. (7) CVT self-excitation measurement, C1 / C2 can be measured simultaneously once wiring, grounding and standard automatic compensation bus capacitor voltage divider effect, do not change the line and any external accessories. (8) Chinese graphic menu, large-screen backlit LCD display clearer, real-time monitoring of current and voltage. (19) optimized circuit design, the positive / consistent anti-wiring accuracy and stability. (10) automatically identify external high voltage test power frequency 40Hz ~ 70Hz, support the commercial power supply, power inverter and series resonant power supply bigger capacity, high voltage dielectric loss test. (11) having anti-wiring and low voltage shielding, grounding bus at 220kVCVT of C11 can be no stitches 10kV anti-wiring dielectric loss measurements. (12) with the computer interface. With this interface, measurement, data processing and report output can also be realized within the instrument measurement software upgrade. It can be integrated into a comprehensive high-voltage test car. Third, the main technical indicators Accuracy: Cx: ± (reading × 1% + 1pF) tgδ: ± (reading × 1% + 0.00040) interference indicators: interference frequency at 200% can still achieve the accuracy of interference power Capacity range: applying high pressure: 3pF ~ 60000pF / 10kV 60pF ~ 1μF / 0.5kV the applied high voltage: 3pF ~ 1.5μF / 10kV 60pF ~ 30μF / 0.5kV Resolution: up 0.001pF, 4 digits tgδ Range: Any resolution of 0.001%, capacitance, inductance, resistance test three kinds of automatic identification.
