Features 1, the use of sophisticated high-pressure high-precision film capacitors, and precision high-pressure glass glaze resistance, high input impedance, reducing the test current, low power consumption and improve the instrument's measurement accuracy and stability; signal processing part, conducted using high-performance OP signal amplification, using the latest technology double integral AD sampling, LCD, a replacement product of two high-voltage electrostatic voltmeter, anti-jamming performance with special shielding technology. Aluminum alloy materials are smooth and glossy surface pressure the ball effectively improve both the electric field distribution of pressure around the ball to prevent point discharge, improve anti-interference ability to measure data. Low indicator enclosed all-metal construction shielding, high voltage divider and low display table using high quality coaxial cable, reduce the impact of high pressure to show value, in order to achieve high stability, high linearity 3, safe and reliable instrument is by high pressure and low pressure indicator constitute divider, high voltage divider using DuPont filling materials, special casting process, the structure is smaller, lighter, internal partial discharge to a minimum, and higher reliability. There is no leakage problems. High-voltage and low-voltage divider at work instruments using coaxial cable, high and low parts of distance, safe and reliable 4, simple operation using DIP switch high and low voltage, AC-DC, and convenient. Direct measurements of the liquid crystal display, simple and intuitive. 5 for the site, easy to carry a portable structure, the whole chassis with aluminum box as can be easily removable. Small size, light weight, easy to carry, easy to use technical parameters Model DBFRC-50 DBFRC-100 DBFRC-150 DBFRC-200 DBFRC-300D BFRC-400 voltage (kV) 50 100 150 200 300 400 DC Frequency (Hz) < 2 AC frequency (Hz) 30 ~ 300 A type Accuracy (%) AC: 1.5% / DC: 1.0% B type Accuracy (%) AC: 1.0% / DC: 0.5% - C Type Accuracy (%) AC: 0.5% / DC: 0.5% - - impedance (MΩ) 650 1200 1700M 2200M 3500M 4300M capacitance (pF) 320 180 150 120 120-500 100-800 dividing ratio of 1000: 1 or 10,000: 1 ratio of special Can be customized size (mm) 150 × 150 160 × 160 200 × 200 260 × 260 800 × 800 cable impedance (Ω) 50/75-scale range of 1, 2 points both high and low range, low range: 0 ~ 20 kV 3, high Range: 20kV- nominal rated voltage of a low range: 0 ~ 200 kV, 2, High Range: 200kV- nominal rated voltage cable length (m) 3456810 Weight (kg) 5.5 6.9 10.6 14.1 23.5 48.2 Dry filling medium inlet temperature range of polymer materials 0 ℃ ~ 45 ℃ Relative humidity <85% RH, non-condensing Altitude <1500 m, high altitude can be customized to limit the use of premises used indoors or under sunny weather conditions for outdoor use five series of high voltage measuring divider product information, application objects and major functional differences are as follows: 1, DBFRC Series AC and DC voltage divider for measuring accuracy of less than 0.5% of the power frequency AC high voltage or high voltage ac below 300Hz, DC accuracy of less than 0.5% of the DC measurement. Such as the provinces, municipal power supply bureau, power plants, various power companies to install or repair a variety of large-scale electric power units and other power companies. 2, DB-PD Series Precision DC voltage divider for measuring accuracy of 0.2%, 0.1% or 0.05% of the DC voltage precision measurement applications.
