1、 Product Overview:

The HZJC-204B oil dielectric loss and resistivity tester is designed and manufactured in accordance with GB/T5564-2007 "Measurement of relative permittivity, dielectric loss factor, and DC resistivity of liquid insulation materials". Used for measuring the dielectric loss factor and DC resistivity of liquid insulation media such as insulating oil. Integrated structure. Internally integrated with main components such as dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss testing bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, etc.

The insulation oil dielectric loss tester adopts fully digital technology for intelligent and automated measurement, equipped with a large screen 5.7-inch TFT pure color LCD touch display and a fully Chinese menu. The test results can be automatically stored and printed out, and operators can proficiently use them without professional training.

Product nickname: Oil dielectric loss tester, Insulation oil dielectric loss tester, Oil dielectric loss tester, Insulation oil dielectric loss and volume resistivity tester, Insulation oil volume resistivity tester.

2、 Product features:

1. The oil cup adopts a three electrode structure that complies with the national standard GB/T5564-2007, with a spacing of 2mm between electrodes to eliminate the influence of stray capacitance and leakage on the dielectric loss test results.

2. The instrument adopts intermediate frequency induction heating PID temperature control algorithm. This heating method has the advantages of non-contact between the oil cup and the heating element, uniform heating, fast speed, and easy control, which strictly controls the temperature within the preset temperature error range.

3. The internal standard capacitor is SF6 gas filled three-point polar capacitor. The dielectric loss and capacitance of this capacitor are not affected by environmental temperature, humidity, etc., ensuring the accuracy of the instrument even after long-term use.

4. Complete 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 will be issued. A temperature limiting relay is installed inside the medium frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay releases and stops heating.

5. Convenient setting of experimental parameters. Temperature setting range: 40-120 ℃ AC voltage setting range, 200-2200V DC voltage setting range: 0-500V.

6. Adopting a large screen TFT pure color LCD touch display for clear display. Simply set up the instrument to automatically perform the test. And automatically store and print test results.

7. The built-in real-time clock test date and time can be saved, displayed, and printed along with the test results.

8. Empty electrode cup calibration function. Measure the capacitance and dielectric loss factor of the empty electrode cup to determine its cleaning and assembly condition. Calibration data is automatically saved for accurate calculation of relative permittivity and DC resistivity.

9. The instrument is based on the RAM9 platform for high testing accuracy and fast speed.
