JKJD 200-1 Insulating oil dielectric loss and resistivity tester

The main functions and features： 1, Oil cup used in line with the national standard GB/T5654-2007 of the three-electrode structure,interelectrode spacing 2mm,can eliminate the stray capacitance and xie leakage effects on dielectric loss test results. 2, The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of the oil cup and the heating body non-contact, even heating, fast speed, convenient control, strict control of the temperature in the temperature error within the preset range. 3, Internal standard capacitor of SF6 gas-filled three-electrode capacitance of the capacitor dielectric loss and electrical capacity independent of ambient temperature, humidity and other effects, the instrument accuracy is ensured even after prolonged use. 4, AC test power supply using AC-DC-AC conversion mode, effectively avoid the influence of voltage and frequency fluctuation on the accuracy of dielectric loss test, even if the generator, the instrument can also run properly. 5, Perfect protection functions. When there is an overvoltage, overcurrent, short-circuit high voltage, the instrument can be quickly cut off the pressure, and issued a warning. When the temperature sensor fails or is not connected, the warning message. In the medium frequency induction furnace equipped with a limited temperature relay, when the temperature exceeds 120 degrees, the relay releases, the heating is stopped. 6, Test parameter settings and convenient. Temperature setting range 0 ~ 125 ℃, the AC voltage setting range 500 ~ 2200V, DC voltage setting range 0 ~ 500V. 7, Using a large-screen LCD display with backlight, clear display. Friendly interface, simply follow the Chinese menu prompt, enter the command, the instrument can be automatically tested. And automatically store and print test results. 8, Built-in real-time clock, the test date, time may be retained with the test results, display and print.
