There is one layer of screen pack, be uniformly equipped with layer of non-woven fabric filter cotton on the outside of screen pack, the filter bores, glass fiber filter cotton,
Activated carbon filter cotton, screen pack, the pore size filter of non-woven fabrics filter cotton reduce successively, can be in batches to the gold in transformer oil
Category impurity is filtered, and prevents metal impurities from being resulted in blockage to the less filter layer in aperture, moreover it is possible to is effectively removed in transformer oil
The larger metal impurities of particle, improve the filter efficiency of cartridge filter, and form filtration channel between magnetite and adjacent magnetite
Setting, the less metal impurities of some particles is adsorbed when passing through filtration channel by both sides magnetite, further increase
The filter efficiency of cartridge filter；
2. filter use for a long time needs to change, magnetic valve and circulating pump can be controlled to stop work by control device
Make, then the filter in cooler bin is split out, the filter after being changed is accessed in decontamination mechanism again
Realize the replacing of filter, substitute mode is simple；
3. flowline and inflow pipeline are alternately formed by connecting by vertical section and ball-type section, ball-type section can effectively increase
The transformer oil and the contact area of air passed through in pipeline, it can substantially increase the cooling effect of oil-filled transformer；
4. the use of cooling oil box so that the transformer oil for cooling down circulation increases, and has been obviously improved the cold of transformer
But effect, the heat-sinking capability of transformer is added, improves the service life of transformer, saved cost.
