Product Description


XHYS101 insulating oil dielectric loss tester is designed and manufactured according to GB/T5654-2007 "Measurement of relative permittivity, dielectric loss factor and DC resistivity of liquid insulating materials".

It is used to measure the dielectric loss factor and DC resistivity of liquid insulating media such as insulating oil. Integrated structure. 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, and DC high voltage source are integrated inside. The instrument adopts all-digital technology, all intelligent automatic measurement, and is equipped with a large-screen (240×128) liquid crystal display. The test results can be automatically stored and printed out, and operators can use it proficiently without professional training.

Features

(1) The oil cup adopts a three-electrode structure in accordance with the national standard GB/T5654-2007, and the distance between the electrodes is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test results.

(2) The instrument adopts intermediate frequency induction heating and PID temperature control algorithm. This 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 dielectric loss and capacitance of the capacitor are not affected by ambient temperature and humidity, so that the accuracy of the instrument can still be guaranteed after long-term use.

(4) The AC test power supply adopts the AC-DC-AC conversion method, which effectively avoids the influence of the mains voltage and frequency fluctuations on the accuracy of the dielectric loss test. Even if the generator generates electricity, the instrument can run correctly.

(5) Perfect protection function. When there is overvoltage, overcurrent, or 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 limit relay in the intermediate frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.

(6) It is convenient to set test parameters. Temperature setting range 0~125ºC, AC voltage setting range
500~2200V, DC voltage setting range is 0~500V.

(7) Adopt large-screen LCD display with backlight and clear display. Friendly man-machine interface, just follow the Chinese menu prompts and input commands, the instrument can automatically test. And automatically store and print test results.

(8) With a real-time clock, the 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 conditions of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculations of relative permittivity and DC resistivity.
