Produce analyte and part free carbon when one, each diverter switch operates, and cause the oil product deterioration.
Two, when making the installation transformer, the microbe that meeting be can not see with dust, impurity and naked eyes in the oil etc. under anaerobic, also can form colloidal impurity and separate out gradually, spread.
Three, owing to the solid insulating material oxidation, thermal cracking generates hydrone and hydrocarbon gas, follows organic acid to produce.
When above-mentioned situation began, the colloidal particle diameter was less, was 10
-9～10
-7M suspends upwards, thus most suspended substances because of oil conservator above transformer, the automatic coalescent continuous motion of colloid, coalescent change is big.Because of action of gravity, part deposition, because of all dead sealings of weldering of metal bellow type oil conservator, and oil-out has only one, and the dunghill after the several years in the metal bellow type oil conservator will more amass the more, and each ripple unit is flexible inconsistent, then will influence the normal reciprocating motion of ripple, make the Buchholz relay would trip, serious damage ripple can not guarantee the safe operation of metal corrugated pipe oil tank in useful life.
The utility model content
The purpose of this utility model provides a kind of multifunction storage oil tank; it overcomes that prior art exists easily makes oil ageing, become of inferior quality defective; can play safeguard protection effect with air insulated; the function that has isolation of purified transformer oil again can also prolong useful life of transformer oil and corrugated expansion pipe.
The purpose of this utility model is achieved in that this device comprises tank body and its interior ripple expansion box of assembling, its technical essential is: the bottom of the ripple expansion box that is made of corrosion resistant plate is encapsulated on the fixed cover in the tank body, the top of box is sealed with along the upper and lower mobile upper cover plate of inner tank wall, upper cover plate is provided with vent valve, tank base is provided with the sump oil purification process chamber and the absolute oil drain chamber of band filter core, and the fuel inlet ball check valve in the sump oil purification process chamber is connected with the filter core that stretches into tank body by the particulate molecular sieve of suction, suction hydrocarbon gas.
Described sump oil purification chamber bottom is provided with blowdown pipe, on the mounting flange that fuel inlet ball check valve is fixed on oil tank of transformer communicates in the sump oil purification process chamber.
