Vertical difference between corrugated inner oil and outer oil

1, which combines the advantages of internal and external oil structures, is more reliable and safer. The corrugated core works vertically, which is the most reasonable, reliable and ideal structure without additional stress. As an air bag (external oil type) instead of an oil bag (internal oil type), the corrugated core eliminates the risk that the power must be cut off immediately once the corrugated core leaks oil, which directly affects the safety of the transformer.

Used as an airbag, it has the function of secondary leakage protection and can provide buffer time for handling defects.

2. The outer wall of the oil storage tank is welded and sealed, and the inside is transformer oil, so there is no need to worry about the corrosion and decay of the outer cover of the internal oil storage tank due to condensation on the inner wall.

3. The problems that the corrugated core of the internal oil storage tank can't bear pressure, is easy to be damaged, can't meet the transformer withstand voltage test, and some products can't be filled with oil in vacuum are solved.

The full range of external vertical oil storage tanks can meet the requirements of transformer full vacuum oil filling and oil tank pressure test, and have the functions of oil level alarm, oil level remote transmission, leakage alarm and so on. And the corrugated airbag will not be damaged due to excessive oil filling.

4. Ultra-flexible waveform design of corrugated airbag and additional flexible processing technology. The additional pressure generated when the product works is 1~5Kpa, which is less than the existing products in the market. There is no need to add any counterweight plate to the corrugated movable end, which will not affect the work and parameter setting of gas relay and pressure relief valve, and there is no need to worry about the influence of corrugated iron core rigidity and oil pressure on transformer seal.

5. The patented technology realizes that the iron core is not dewed, the corrugated iron core is completely immersed in transformer oil, and the inner surface is a heat dissipation surface, so it does not have dew condensation conditions and does not produce dew condensation.

The running test shows that even if half a glass of water is poured into corrugated medium paper, it will evaporate after two weeks.

6. All products adopt a single set of corrugated cores to eliminate multiple sets of parallel invalid spaces and realize super compensation ability.

Under the same compensation volume, the product size is reduced by 30%, the total number of welds is reduced by 50%, and the product reliability is greatly improved.

7. The external magnetic coupling turnover oil level meter designed by patented technology accurately displays the position of the extended end of bellows to the external oil level meter through magnetic coupling, which is completely isolated from the oil storage cavity, convenient for inspection and replacement, safe, reliable, clear and accurate. 8, concise and beautiful, without any dead ends and redundant edges.
