The method of collection test waste oil.
Background technique
In oil for electric power experiment work, it is often necessary to relevant pretreatment operation is carried out to insulation oil samples, such as to oil
The part of detecting of test apparatus, carries out accurately adjusting etc. to the volume of insulation oil samples at the oily cleaning of test vessel progress.Due to
Pilot project is more, in addition test apparatus distribution is more dispersed, testing crew is frequently necessary to the mobile glass equipped with insulation oil samples
Glass container carries out the test of oil sample on different test apparatuses.In frequent mobile insulating oil sample, easily because of test
There is phenomena such as insulation oil samples are surprisingly lost, sample is contaminated, sample container and tester are broken in personnel's misoperation, sternly
Ghost image rings the development of oil test work.
In addition, can also generate a large amount of test waste oil during insulating oil test, conventional way is to test these
Waste oil is poured directly into open interim wasted oil bucket and collects, then by the direct waste treatment of oil.Since interim wasted oil bucket does not have
Complete seal approach, so that the exposure storage in air for a long time of test waste oil, it is continuous under the action of various extraneous factors
Oxygenolysis generates the volatilization oil vapour being largely harmful to the human body, seriously polluted the environment of laboratory.And many tests are given up
Oil itself or fresh oil, it is mixed with old oil after being introduced into interim wasted oil bucket, due to can not categorised collection, lose recycling
Value, can only make together waste treatment with old oil, a large amount of meaningless losses of insulating oil not only be caused, also easily because dealing with improperly
