I. Overview
In order to prevent transformer failure better and more comprehensively, the power
industry has set higher requirements for the safe operation of transformers at all levels,
and the test requirements for the gas content of transformer oil have also increased
accordingly.
The insulating oil gas content tester is based on the DL423-91 power industry
standard and relevant national standards. It uses imported high-precision sensors and the
latest sensor technology. The determination of gas content in ultra-high pressure oil-filled
equipment is an ideal test equipment in the laboratory. It will make your work easier!
Its main features are as follows:
1, all metal structure, to avoid the glassware tester fragile, poor sealing and other
problems.
2. The inlet differential pressure sensor with high precision and stability is applied to make
the test data more accurate and more repeatable.
3. The test circuit contains sensors for measuring atmospheric pressure and ambient
temperature. No matter when and where you are, you can automatically measure the
temperature and atmospheric pressure of the environment you are in, automatically
convert to the air content at 0 degrees of standard atmospheric pressure, and display it
directly on the LCD screen, making your work easier.
4. The unique anti-calibration test procedure of gas injection can conveniently test
whether the calibration or measurement of the instrument is correct.
5. The test time of oil sample is short, and the whole test time only needs about seven
minutes.
6. During the test of the instrument, the operation of the vacuum pump is controlled by the
instrument itself according to the state, which greatly reduces the noise and prolongs the
service life of the vacuum pump.
7. The instrument can automatically store dozens of last test data, and simultaneously
store test time, temperature, atmospheric pressure, etc., so as to check the data
