Integrated measurement of dielectric loss and volume resistivity of insulating oil
Three, the integration of insulating oil dielectric loss and volume resistivity tester is introduced:
:
Integrated oil dielectric loss and volume resistivity of insulating tester is used for high precision instrument insulation oil liquid dielectric of dielectric loss angle and the volume resistivity. Integrated structure. The internal integration of the dielectric loss oil cup, Wen Kongyi, a temperature sensor, dielectric loss measuring bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source and other major components. The heating part adopts the most advanced high frequency inductive heating mode, heating mode has the advantages of the cup and the heating body non-contact, even heating, fast speed, convenient control etc.. 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. The internal standard capacitors SF6 inflatable 3-pole capacitor, dielectric loss and capacitance of the capacitor is not affected by environmental temperature, humidity, ensure instrument after a long time still consistent accuracy.
