Overview
Many power systems, railway systems, large-scale petrochemical plants and enterprises have a lot of electrical equipment whose internal insulation are mostly oil-filled insulation type, and therefore, test on insulating oil dielectric strength is common and necessary. To meet the needs of the market, we have developed and produced a series of insulating oil dielectric strength testers according to national standard GB/T507-2002, industry standard DL429.9-91 and the latest Electric Power Industry Standard DL/T846.7-2004 by ourselves. This instrument, by using a single-chip microcomputer as the core, can operate in full automation with high accuracy, greatly improving work efficiency and reducing the labor intensity of workers. Moreover, it is small in size and convenient to carry.

Features 1, the oil cup conforms to the standard GB/T5654-2007 three electrode structure, the inter electrode spacing is 2mm, it can eliminate stray capacitance and the effect of leakage on the dielectric dissipation test results. It has oil discharge electromagnetic switch, the operator can remove the sample oil from oil cup under the condition of don’t remove the oil cup, and can clean the oil cup with sample oil. 2, the instrument uses induction heating, PID temperature control algorithm. The heating mode has the advantages of oil cup and heating body non-contact, heat evenly, fast, and easy to control the temperature strictly controlled within the preset temperature error range. 3, the internal standard capacitor is the SF6 inflatable three electrode type capacitor. The dielectric dissipation and capacitance of the capacitor are not affected by the ambient temperature and humidity. The precision of the instrument is guaranteed after long time use. 4, AC test power supply using AC-DC-AC conversion, which can effectively avoid the influence of mains voltage and frequency fluctuation on the accuracy of dielectric dissipation test. Even if the generator is generating electricity, the instrument can run correctly. 5, this instrument has a perfect protection function. When there is over-voltage, over-current, high voltage short circuit, the instrument can quickly cut off the high pressure, and issue a warning message. When the temperature sensor fails or is not connected, a warning message is issued. In the medium frequency induction heating furnace with limit temperature relay, when the temperature exceeds 120 degrees, the relay release, heating stop. 6, test parameter setting is convenient. The temperature setting range is 0 ~ 125 ?, the AC voltage setting range is 500 ~ 2200V, and the DC voltage setting range is 0 ~ 500V. 7, the instrument uses a large-screen LCD display, with backlight, clear display and so on. Friendly man-machine interface, just follow the English menu prompts, enter the command, the instrument can be automatically tested. And automatically store and print test results. 8, this instrument has a real-time clock, test date and time can be saved with the test results, display and print. 9, this instrument has an empty electrode cup calibration function. It can measure the capacitance of the empty electrode cup and dielectric dissipation factor to determine the cleaning and assembly of empty electrode cups.
