KR15B intelligent integrated precision oil dielectric loss volume resistivity tester is a high precision instrument for dielectric loss angle and volume resistivity of liquid insulating medium such as insulating oil. Integrated structure. It integrates 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 and DC high voltage source. The heating part adopts the most advanced high-frequency induction heating method at present, and the heating method has the advantages of non-contact between the oil cup and the heating body, uniform heating, high speed and convenient control. The AC test power supply adopts the Ac-Dc-Ac conversion method to effectively avoid the influence of the mains voltage and frequency fluctuation on the accuracy of the dielectric loss test. Even if the generator generates electricity, the instrument can operate correctly. The internal standard capacitor is SF6 gas-filled three-pole capacitor. The dielectric loss and capacitance of the capacitor are not affected by ambient temperature and humidity, ensuring consistent accuracy after long-term use.
The instrument adopts all-digital technology, all intelligent automatic measurement, equipped with large screen (240×180) liquid crystal display, full Chinese menu, Chinese prompts in every step, test results can be printed and output, operators can do without professional training.
