IEC 60247 INSULATION OIL DIELECTRIC LOSS AND RESISTIVITY TESTER

Introduction Insulation Oil Dielectric Loss And Resistivity Tester

Insulation oil dielectric loss and resistivity tester is designed and manufactured according to GB/T5654-2007/IEC 60247 "Measurement of Relative Capacitance, Dielectric Loss Factor and DC Resistivity of Liquid Insulating Materials". Used for the measurement of dielectric loss factor and DC resistivity of insulating oil and other liquid insulating media. All-in-one structure. Internal integration of the main components such as dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, etc. The instrument adopts all digital technology, all intelligent automatic measurement, equipped with color large screen LCD, full Chinese menu, each step has Chinese prompts, test results can be automatically stored and printed out, the operator does not need professional training can be skilled to use.

Characteristic

(1) The oil cup adopts the three-electrode structure conforming to the national standard GB/T5654-20077/IEC 60247, with the inter-pole spacing of 2mm, which can eliminate the influence of stray capacitance and diarrhea leakage on the dielectric loss test results.
(2) The instrument adopts medium frequency induction heating and PID temperature control algorithm. The heating method has the advantages of non-contact between the oil cup and the heating body, uniform heating, fast speed and convenient control, so that the temperature is strictly controlled within the preset temperature error range.
(3) The internal standard capacitor is SF6 gas-filled three-electrode capacitor, the capacitor's dielectric loss and capacity are not affected by ambient temperature and humidity, so that the accuracy of the instrument is still guaranteed after a long time of use.
(4) AC test power supply adopts AC-DC-AC conversion method, effectively avoiding the influence of utility voltage and frequency fluctuation on the accuracy of dielectric testing, even if the generator generates electricity, the instrument can also operate correctly.
(5) Perfect protection function. When there is over-voltage, over-current, high-voltage short circuit, the instrument can quickly cut off the high voltage and issue a warning message. When the temperature sensor fails or is not connected, a warning message is issued.
There is a temperature-limiting relay in the medium-frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.
(6) Easy setting of test parameters. Temperature setting range 0～120℃, AC voltage setting range
500 ~ 2200V, DC voltage setting range of 300 ~ 500V.
(7) The use of large screen LCD display, with backlight, clear display. Friendly human-machine interface, just follow the Chinese menu prompts, input commands, the instrument can automatically carry out the test. And automatically store and print test results.
(8) Real-time clock, test date and time can be saved, displayed and printed with the test results.
(9) Empty electrode cup calibration function. Measure the electric capacity and dielectric loss factor of the empty electrode cup to judge the cleaning and assembly condition of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative capacitance and DC resistivity.
