Dielectric constant experimental device GCSTD-C power frequency automatic dielectric loss tester Meet the standard: GB/T1409-2006 Recommended method for measuring the electrical permittivity of electrical insulating materials at power frequency, audio, high frequency and dielectric loss factor I. Overview The dielectric loss insulation test can effectively find the overall moisture deterioration and deterioration of electrical equipment insulation, as well as local defects, etc., and is widely used in electrician manufacturing, electrical equipment installation, handover and preventive tests. The anti-interference dielectric loss tester adopts the variable frequency power supply technology, and uses the single chip microcomputer and electronic technology to perform automatic frequency conversion, analog/digital conversion and data calculation, and achieves the functions of strong anti-interference ability, fast test speed, high precision and easy operation. The variable frequency power supply adopts high-power switching power supply, output 45Hz and 55Hz pure sine wave, automatic pressure, can provide voltage up to 10kV; automatically filter out 50Hz interference, suitable for field test of large electromagnetic interference such as substation. Second, the performance characteristics 1. The instrument has high measurement accuracy and can meet the oil dielectric loss measurement requirements. Therefore, only the standard oil cup and the special test line can be used to measure the oil dielectric loss. 2, using frequency conversion technology to eliminate 50Hz power frequency interference on-site, even in the environment of strong electromagnetic interference can also measure reliable data. 3. Over-current protection function, the instrument is not damaged when the sample is short-circuited or broken down. 4, with standard capacitors and high-voltage power supply, easy to field test, reduce field wiring. 5. The instrument adopts a large-screen liquid crystal display. The test process is intuitive and easy to operate through the Chinese menu prompt. Dielectric constant experimental device Third, technical indicators 1. Measurement range: Capacitance value: 4 ~ 60000 pF Dielectric loss value: 0 ~ 100% 2, the maximum error: capacitance accuracy: ± (1.0% × reading ± 1 pF) Dielectric loss accuracy: ± (1.0% × reading ± 0.04%) 3. Resolution: Capacitance resolution: minimum resolution 0.001 pF Dielectric loss resolution: minimum resolution 0.001% 4, high voltage output: 0.5 ~ 10kV45Hz and 55Hz, current output ≤ 200mA 5, low voltage output: output voltage 3 ~ 50V output current 3 ~ 30A 6, power supply: AC 220V ± 10%, 50Hz or generator power supply
