4）Oil sample is connected in sampler, takes Man Houzai that sampler is taken out into housing by base；
5）After sampling is finished, enclosure interior is cleaned, is that next time is standby.
Beneficial effects of the present invention：
In order to ensure the cleannes in transformer oil sample granularity sampling process, the survey that environmental factor is brought is reduced to greatest extent
Error is measured, the present invention proposes a kind of field sampling protection device.Sampler is positioned over shell by bottom opening during sampling
In vivo, oil sample is flowed into sampler by injection port, and the oil sample sputtered in sampling process can be accepted by housing, and sampling is protected
Protection unit has converged the oil sample of sputtering, while playing the effects such as isolation dust storm, dust.
The present invention can effectively reduce external environment influence, while the environment at sampling scene is protected again, practical, behaviour
Make simple, it is convenient and swift, it is safe and reliable.
