Product Description

Specification

XHYS101 Insulation oil dielectric loss tester 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. Internally integrated dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, megger, DC high voltage source and other main components.

The interior of the instrument adopts all-digital technology, all intelligent automatic measurement, equipped with a large-screen (240×128) LCD display, full English menu, every step has English prompts, the test results can be automatically stored and printed out, and the operator does not need to be professional. Training can be used proficiently.

Features (1) The oil cup adopts a three-electrode structure conforming to the national standard GB/T5654-2007, and the distance between electrodes 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 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 can be strictly controlled within the preset temperature error range.

(3) The internal standard capacitor is an SF6 gas-filled three-electrode capacitor. The dielectric loss and capacitance of this 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 can effectively avoid the influence of the mains voltage and frequency fluctuation on the accuracy of the dielectric loss test. Even if the generator generates power, the instrument can also operate 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-limiting relay in the medium-frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.

(6) The test parameters are easy to set. Temperature setting range 0～125℃, AC voltage setting range 500~2200V, DC voltage setting range 0~500V.

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

(8) With its own real-time clock, the test date and time can be saved, displayed and printed along 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 status of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
