Description

The vacuum static electricity oil conditioner
A kind ofly be used for purifying transformer oil moisture content, gas and well cuts particulate vacuum static electricity oil conditioner.
Transformer oil is subjected to the influence of ambient conditions in production, transportation, storage process, can produce materials such as moisture content, gas, impurity particle, and fluid must purify just before use can reach service requirements.
Existing vacuum oil purifier mainly is made up of strainer, vacuum pump, vacuum degasser, well heater, oil drain pump and strainer etc.Impurity particle in the fluid comes filtering by strainer, the filtering accuracy of strainer depends on the precision of filtration mediums such as the filter paper of strainer or filter cloth, the precision height of medium, fluid is big by the resistance of strainer, the easily sticking impurity of filter core, so, must be often renew cartridge more, make troubles and cause economically waste to use.The voltage breakdown of the transformer oil of usually conduct is below the 70KV.
The purpose of this utility model is to provide a kind of transformer oil efficient height, vacuum static electricity oil conditioner that filtering accuracy is high of purifying.The voltage breakdown of the transformer oil after the purification can reach 90KV.
The purpose of this utility model is realized by following technical scheme: a kind of vacuum static electricity oil conditioner, comprise and being fixed on the base plate (12), strainer (1) by the pipeline connection, electric heater (2), by vacuum tank (9), the liquid level valve (7) that is provided with in the vacuum tank (9), the vacuum degasser (3) that degassing element (8) is formed, vacuum pump (4), oil drain pump (6), its special character is: also comprise by casing (19), be fixed on the oil inlet pipe (13) on casing (19) sidewall, insulation joist (21), insulation joist (21) go up fixed several just, auxiliary electrode plate (16,17), just, auxiliary electrode plate (16,17) collecting plate (18) that is provided with between, go up fixed loam cake (20) at casing (19), go up fixed oil outlet pipe (11) at loam cake (20), electrostatic power unit (14), insulation of the high-voltage contact (23) of electrostatic power unit (14) and loam cake (20) and the electrostatic oil cleaner device (5) that contacts and form with positive plate (16), the oil inlet pipe (13) of electrostatic oil cleaner device (5) is connected with oil drain pump (6).
Vacuum static electricity oil conditioner of the present utility model is compared with existing vacuum oil purifier, and oil conditioner of the present utility model is by being provided with the strainer that the electrostatic oil cleaner device replaces known oil conditioner.Avoid the inconvenience that frequent filter rinsed brings and changed the waste that strainer causes.Has the transformer oil of purification efficient height, the filtering accuracy advantages of higher.The voltage breakdown of the transformer oil after the purification can reach 90KV.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
