Density detection for the treatment of oil filter equipment used for waste insulation oil
2018/5/15 Viewers:
The main application areas of insulating oil, insulating oil and other liquid insulating medium need to test the dielectric loss angle and volume resistivity, such as the use of MS101Y insulating oil dielectric loss tester.
1. arc extinguishing makes the arc in the middle of the contact quickly extinguish.
2. insulation makes each pole of the switch mutually insulated, while the conductive part of the switch is insulated from the oil tank.
3. anticorrosion prevents contact between contacts and air to avoid contact oxidation.
4. the heat emitted by the heat sink contacts absorbs the oil and rapidly dissipates heat by convection in the tank. Less oil circuit breakers, because of the small amount of oil, the oil only plays an arc extinguishing function. Its outer casing is usually electrified, and it must not be touched.
The following matters should be paid attention to when measuring the density of oil products.
(1) densitometer must be wiped clean before use. After wiping, do not grasp the following parts of the highest dividing line, so as not to affect the reading.
(2) the diameter of the measuring cylinder for measuring the density of the test oil should be twice larger than the diameter of the body by the densitometer, so as to prevent the density meter from colliding with the inner wall and influence the accuracy, and its height should be appropriate.
(3) when the density meter is immersed in the oil test, do not use the hand to push down the densitometer. It should be gently placed to prevent the density gauge from sinking at the bottom of the measuring cylinder and breaking the densitometer.
(4) the position of the readings, regardless of the determination of the transparent or dark oil, should be read on the upper edge of the liquid surface, and the eye and the upper edge of the liquid must be at the same level when reading.
(5) do not take the end of the density gauge sideways to prevent breaking.
(6) if the density scale displacement of the densitometer is found and the glass has cracks, it should be stopped.
(7) the bubbles will be affected when bubbles are inside or on the surface of the sample, and bubbles should be removed before testing.
(8) when measuring the density of mixed oil, it must be stirred evenly.
(9) while reading, the temperature of the specimen should be recorded.
