Product Introduction
In the preventive insulation test of power equipment it is required to measure the insulation oil parameters of power equipment periodically. The measurement of dielectric loss and resistivity of insulating oil is one of the most important. For a long time most of them adopt the bridge method for measurement which is complicated in operation and the measurement accuracy is affected by many factors thus leading to a large measurement error. With the rapid development of electronic technology and the power industry for small volume light weight easy to operate rapid measurement high precision measurement instrument requirements I refer to domestic and foreign related instruments developed in the domestic leading insulation oil dielectric loss factor and dc resistivity tester. The instrument is designed and manufactured according to gb5654-2007 and related standards. It is controlled by microcomputer easy to use high measurement accuracy high test efficiency and greatly reduces labor intensity.

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. Calibration data is automatically saved for accurate calculation of relative permittivity and DC resistivity.
Wollastonite
Wollastonite is one of the most versatile minerals. It is a naturally found mineral that is a mixture of calcium, silicon and oxygen. However, it is majorly found in the regions of Rajasthan, Gujarat and some parts of Tamil Nadu in India
The physical properties of Wollastonite include an eclectic needle looking structure which is high in brightness and has superior tones of white. It also has low moisture, oil-absorbing and high thermal stability with less solubility in water. It is low in volatility and has a high melting temperature. Wollastonite has medium hardness with rank of 4.5 on Mohâ??s scale.
