Technical Field

[0001] The utility model relates to the technical field of oil medium testers, in particular to an oil medium loss and resistivity tester. Background Art

[0002] The existing oil dielectric tester adds the oil to be tested into the test tank for measurement. However, when it is used, it does not have a device for filtering the oil, which will cause the measurement results to be affected by impurities in the oil. For example, a Chinese patent discloses an "insulating oil dielectric loss and resistivity tester" with an application number of "202022593135.7". This device includes an insulating oil dielectric loss and resistivity tester body; a holder, which is arranged at the bottom of the insulating oil dielectric loss and resistivity tester body; a rectangular frame, which is slidably installed in the casing; a sliding frame, which is fixedly installed on the top of the rectangular frame, and the top of the sliding frame extends outside the casing and is fixedly connected to the bottom of the holder. This equipment has the advantages of being able to freely adjust the height, convenient transportation, fixed and stable, and able to reduce surrounding dust. However, when it is used, it does not have a device for filtering the oil, and the oil is not filtered, which may cause the test results to be affected by impurities, particulate matter and pollutants, thereby reducing the test accuracy. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art, and provides an oil medium loss and resistivity tester. By adding oil into the filter box, the oil passes through the filter membrane to filter out its own impurities, and then enters the test tank through the leakage port to be measured, which can improve the test accuracy. The filter membrane can effectively remove impurities, suspended matter and solid particles in the oil to ensure the purity of the oil during the test, which can avoid the influence of impurities on the test results, thereby improving the accuracy and reliability of the test, and the filter membrane can prevent impurities from entering the test tank, reduce the pollution and friction corrosion inside the test tank, and protect the cleanliness and integrity of the test tank. The heating plate at the bottom of the test tank is heated and the insulation layer is used for insulation, so that the measuring tank has a constant temperature environment, which can improve the stability of the test. The resistivity of the oil medium will change with the temperature, so keeping the constant temperature inside the test tank can eliminate the temperature influence, improve the stability and reliability of the test, and accelerate the test speed. The heating plate and the insulation layer of the heating tank can quickly reach the required temperature, shorten the test time, and improve work efficiency.

The above components can prevent the equipment from sliding and displacing easily.

[0012] Beneficial Effects

[0013] 1. Compared with the prior art, the oil dielectric loss and resistivity tester can improve the test accuracy by adding oil into the filter box, filtering out the impurities in the oil through the filter membrane, and then entering the test tank through the leakage port for measurement. The filter membrane can effectively remove impurities, suspended matter and solid particles in the oil to ensure the purity of the oil during the test, which can avoid the influence of impurities on the test results, thereby improving the accuracy and reliability of the test. The filter membrane can prevent impurities from entering the test tank, reduce pollution and friction corrosion inside the test tank, and protect the cleanliness and integrity of the test tank.

[0014] 2. Compared with the existing technology, the oil dielectric loss and resistivity tester has a constant temperature environment in the measuring tank through heating by the heating plate at the bottom of the test tank and insulation by the insulation layer, which can improve the stability of the test. The resistivity of the oil medium will change with temperature, so keeping the constant temperature inside the test tank can eliminate the temperature influence, improve the stability and reliability of the test, and accelerate the test speed. By heating the heating plate and insulation layer of the heating tank, the required temperature can be quickly reached, shortening the test time and improving work efficiency.
