Abstract
The utility model discloses a removal-free dielectric strength measuring oil cup capable of automatically discharging oil, aiming to solve the problems of the existing insulating oil dielectric strength measuring instrument that the oil cup needs to be repeatedly installed and removed, the operation is complex and testing data are inaccurate. The dielectric strength measuring oil cup comprises a testing oil cup and an electrode inserted into the testing oil cup, the testing oil cup is funnel-shaped, the bottom of the testing oil cup is provided with an oil discharging hole with the diameter being 8-12mm, the oil discharging hole is externally connected with an oil discharging pipe, and the oil discharging pipe is provided with a solenoid valve for opening and closing control. When oil samples to be tested are changed, the opening and closing of the oil discharging pipe can be controlled through the solenoid valve, the oil cup needs not to be repeatedly installed and removed, the pollution of the oil samples to be tested and the oil cup caused by oil discharging, cleaning and oil injection can be avoided, the accuracy of testing data can be improved, possible electric shock and fire hazards can be eliminated, and the working efficiency can be increased.
Description
Technical field
The utility model relates to a kind of dielectric oil dielectrical strength determinator, but relates in particular to a kind of dielectric strength mensuration lubricating cup of automatic oil draining.
Background technology
Existing dielectric oil dielectrical strength analyzer structure comprises standard testing lubricating cup, potential electrode of splendid attire test specimen etc.In the time need measuring to the dielectric strength of certain batch of insulation oil sample, at first splendid attire to be tested the lubricating cup of oil sample and in analyzer, remove the back taking-up, pour out waste oil sample in the lubricating cup, lubricating cup is cleaned, inject then and treat the formation testing sample.Reinstall lubricating cup, start the mensuration program; Mensuration finishes when changing oil sample, removes in the analyzer again and takes out lubricating cup, pours out waste oil sample in the lubricating cup, cleans lubricating cup, injects the new formation testing sample for the treatment of, reinstalls lubricating cup, carries out so circularly.Its shortcoming is: when 1, changing oil sample, laboratory technician's finger is touched the lubricating cup inwall easily, and finger sweat and dirt are retained in the lubricating cup, influences oil quality; 2, repeated disassembled and assembled can change two potential electrode distances, and has a strong impact on determination data, has also damaged lubricating cup and analyzer; 3, during the dismounting lubricating cup,, the high pressure Danger Electric shock risk is arranged if protection of instrumentation lost efficacy; 4, during actual dismounting lubricating cup, usually with the oil sample water clock in analyzer, when analyzer generation electric fault, easy initiation fire; 5, the not only numerous and diverse work efficiency of repeated disassembled and assembled lubricating cup but also low.
The utility model content
The purpose of this utility model is to overcome the prior art defective, but provides a kind of dielectric strength of exempting from the dismounting automatic oil draining to measure lubricating cup.
But the technical solution of the utility model is achieved in that the dielectric strength of automatic oil draining and measures lubricating cup, comprise the test lubricating cup and insert the electrode of testing in the lubricating cup, it is, described test lubricating cup is an infundibulate, in test lubricating cup bottom outage is arranged, the external draw-off pipe of outage is equipped with the solenoid valve of controlling folding on the draw-off pipe.
It is that described outage diameter is 8～12mm.
The utility model is when changing the test oil sample, by the folding of solenoid control draw-off pipe, do not need the repeated disassembled and assembled lubricating cup, stopped because of in oil extraction, cleaning, the oiling operating process to the pollution of tested oil sample and lubricating cup, improved the accuracy of determination data, eliminate contingent electric shock and disaster hidden-trouble, improved work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1-tests lubricating cup, 2-outage, 3-solenoid valve, 4-draw-off pipe, 5-electrode.
Embodiment
Be further described below in conjunction with accompanying drawing.
As shown in the figure, but the dielectric strength of automatic oil draining is measured lubricating cup, comprise test lubricating cup 1 and insert the electrode of testing in the lubricating cup 15, satisfying under GB/T507-2002 or the prerequisite of DL429.9-91 standard, will test lubricating cup 1 bottom and make funnel type, be provided with outage 2 in test lubricating cup 1 bottom to the lubricating cup requirement, outage 2 diameters 8～12mm, outage 2 external draw-off pipes 4, draw-off pipe 4 will have oil resistance preferably, is equipped with the solenoid valve 3 of control folding on the draw-off pipe 4.
Before measuring dielectric oil dielectrical strength, prepare a clean syringe earlier, draw an amount of oil sample to be measured with clean syringe, inwall and electrode 5 to test lubricating cup 1 on analyzer carry out two to three cleanings, clean the back oil sample and can pass through outage 2, solenoid valve 3 and oil-drain pipe 4 are discharged outside the analyzer, close solenoid valve 3 subsequently, in test lubricating cup 1, slowly inject an amount of oil sample to be measured by the technical standard requirement, and start the test routine of dielectric oil dielectrical strength analyzer by technical standard, opens solenoid valve 3 oil extractions again after test finishes, the waste oil sample of having tested is passed through outage 2, solenoid valve 3, draw-off pipe 4 is discharged outside the analyzers, repeats above step when measuring next oil sample.
Claims (2)
1. but the dielectric strength of automatic oil draining is measured lubricating cup, comprise the test lubricating cup and insert the electrode of testing in the lubricating cup, it is characterized in that: described test lubricating cup is an infundibulate, in test lubricating cup bottom outage is arranged, the external draw-off pipe of outage is equipped with the solenoid valve of controlling folding on the draw-off pipe.
2. but the dielectric strength of automatic oil draining according to claim 1 is measured lubricating cup, and it is characterized in that: described outage diameter is 8～12mm.
