Transformer Oil-immersed Transformer Oil Storage Cabinet And Cooling Method-ERG
- May 17, 2018 -

Five, oil-immersed transformer oil storage cabinet


Transformer oil storage tank has two functions, one is to provide thermal expansion and contraction of the transformer oil in the tank; the other is to separate the transformer oil from the outside atmosphere to prevent transformer oil aging.


As shown in Figure 1, the capsule-type oil conservator, which uses rubber capsules to separate the transformer oil from the outside atmosphere, provides transformer oil with space for thermal expansion and contraction.


2. Diaphragm-type oil conservator, using rubber diaphragms to separate the transformer oil from the outside atmosphere, and provide transformer oil with space for thermal expansion and contraction.


3. Corrugated oil conservator, a metal expander made of metal corrugated sheets separates the transformer oil from the outside atmosphere, and provides transformer oil with space for thermal expansion and contraction. Corrugated oil storage tanks are divided into internal oil type and external oil type. Internal oil type performance is better, but the volume is larger.



Six, oil-immersed transformer cooling method


As shown in Figure 1, the symbol for the cooling method

The first letter: O-mineral oil, K-synthetic insulation, L-insulated gas.

The second letter: N-natural convection cycle, F-forced oil cycle, D-forced-orientation cycle.

The third letter: A-air, W-water.

The fourth letter: N-natural convection, F-forced circulation (fan, pump).
