Insulation oil volume resistivity detector

Overview

ceaseInsulation oil volume resistivity detectorIt is a high-precision integrated testing instrument designed and manufactured in accordance with GB/T5564-2007 "Measurement of relative permittivity, dielectric loss factor, and DC resistivity of liquid insulation materials". It is mainly used for measuring the dielectric loss factor and DC resistivity of liquid insulation media such as insulating oil. 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, DC high voltage source, etc. The instrument utilizes advanced measurement and control technology to fully automate processes such as temperature rise, control, high-speed data sampling, computation, display, printing, and storage. Advanced measurement principles and highly digitized technology make your work easier and more convenient.

The instrument adopts fully digital technology internally, with intelligent and automated measurement. It is equipped with a large screen color touch screen, a fully Chinese menu, and Chinese prompts for each step. The test results can be printed out, and operators can proficiently use them without professional training.

Instrument Features

1. Highly automated, temperature rise, measurement of dielectric loss, and measurement of resistivity can be completed in one go;

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

3. 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 element, uniform heating, fast speed, and easy control, which strictly controls the temperature within the preset temperature error range.

4. Adopting advanced DSP and FFT technology to ensure data stability, accuracy, and reliability.

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

6. Large screen color touch screen, Chinese operation menu, convenient conversation, simple and clear operation, easy to understand at a glance.

7. Equipped with warm reminders such as opening the lid to break high voltage, short circuit of high and low voltage electrodes in the oil cup, etc., to eliminate safety hazards and ensure the personal safety of operators and the normal operation of equipment.

8. Equipped with a real-time clock, the test date and time can be saved, displayed, and printed along with the test results; The device can display the ambient temperature and detect the experimental environment in real time.

9. Automatically store measurement data, capable of storing 100 sets of measurement data.

10. 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.
