Oil Dielectric Loss Tester
Product Characteristics
1, the oil cup adopts the three-electrode structure in line with the national standard GB/T5654-2007, the electrode spacing is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test results.
2, the instrument adopts medium frequency induction heating, 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, convenient control, etc., so that the temperature is strictly controlled within the preset temperature error range.
3, the internal standard capacitor is SF6 inflatable three-pole capacitor, the dielectric loss and capacitance of the capacitor are not affected by ambient temperature, humidity, etc., so that the accuracy of the instrument is still guaranteed after a long time of use.
4, AC test power supply using AC-DC-AC conversion mode, effectively avoid the mains voltage and frequency fluctuations on the dielectric loss test accuracy, even if the generator generation, the instrument can operate correctly.
5, perfect protection function. When there is overvoltage, overcurrent, high voltage short circuit, the instrument can quickly cut off the high voltage, and send a warning message. A warning message is issued when the temperature sensor fails or is not connected. A limited temperature relay is provided in the medium frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.
6. Convenient setting of test parameters. The temperature ranges from 0 to 120 ° C. The AC voltage ranges from 200 to 2200V. The DC voltage ranges from 0 to 500V.
7, the use of large screen TFT pure color LCD touch display, clear display. With a simple setup, the instrument can be tested automatically. And automatically store and print test results.
8, with 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 capacitance 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 permittivity and DC resistivity. 10, the instrument with RAM9 platform as the core, high test accuracy, fast speed.
