Background technique
Need to carry out vacuum oil inside mutual inductor, conventional traditional mutual inductor carries out oiling using vacuum impregnating lubricating cup, very
Oil eliminator is free of in empty oil filling pipeline, it, can be in vacuum impregnating lubricating cup since oiling later period mutual inductor pasta gradually tends to filled state
It generates a large amount of foams to enter by mistake through in vacuum hose, and then forms " oil sealing " at the low-lying place of vacuum hose and block vacuum hose, sternly
Ghost image rings the product handling system technological effect of mutual inductor, and partial discharge is unqualified when most direct consequence is exactly manufacture test, and form is gas
Body electric discharge.
Utility model content
The utility model aim is to provide a kind of tooling for improving mutual inductor partial discharge qualification rate, can be to avoid producing in vacuum tube
Oil generation blocks plug, and strong operability avoids generating oil sealing phenomenon in vacuum tube, ensure that the partial discharge qualification rate of finished product delivery test,
Rework cost is substantially reduced, the above problem present in background technique is solved.
The technical solution of the utility model is:
A kind of tooling improving mutual inductor partial discharge qualification rate includes mutual inductor, vacuum impregnating lubricating cup, oil eliminator, vacuum pump
And filling pump；Vacuum impregnating lubricating cup is equipped at the top of mutual inductor, vacuum impregnating lubricating cup is connect by oil fuel tube with filling pump, vacuum impregnating lubricating cup
It is connect by oil inlet pipe with oil eliminator, oil eliminator is controlled to a vacuum pump by vacuum tube, the oil eliminator, comprising upper
Lid, cylinder, oil baffle, bottom cover and leak oil line, the top and bottom of cylinder pass through respectively upper cover and bottom cover closing, vacuum tube and into
Oil pipe both passes through upper cover and enters cylinder, and oil inlet pipe connects leak oil line in cylinder, and oil leak bottom of the tube is equipped with oil baffle, sets on bottom cover
There is oil exit pipe.
The leak oil line is equipped with the pipe that keeps out the wind, and is equipped with vent valve above upper cover.
Pass through screw rod bolt fastening between the upper cover and bottom cover.
The oil fuel tube is equipped with oiling valve；Oil inlet pipe both ends are respectively equipped with oil return valve one and oil return valve two；Very
Blank pipe is equipped with vacuum valve.
In use, filling pump passes through oil fuel tube to mutual inductor oiling, in a large amount of foams that the oiling later period generates through vacuum impregnating
After lubricating cup, oil eliminator is flowed by oil inlet pipe, is collected in the bottom of oil eliminator, the low-lying place for avoiding enter into vacuum tube is formed
" oil sealing ", it is ensured that unobstructed, the final partial discharge qualification rate for guaranteeing manufacture test of vacuum line.The volume of oil eliminator is according to most
Big oil weight product overflows depending on the total amount of formation of foam oil.
The beneficial effects of the utility model are: can be to avoid oil sealing blocking is generated in vacuum tube, strong operability avoids vacuum
Oil sealing phenomenon is generated in pipe, be ensure that the partial discharge qualification rate of finished product delivery test, is substantially reduced rework cost.
