Detailed description of the invention
Embodiments provide and a kind of filter the technique of fiber grain in transformer oil, be used for solving prior art side
Method filters fiber grain speed in transformer oil slow, the longest, inefficient problem.
For making the goal of the invention of the present invention, feature, the advantage can be the most obvious and understandable, below in conjunction with the present invention
Accompanying drawing in embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that disclosed below
Embodiment be only a part of embodiment of the present invention, and not all embodiment.Based on the embodiment in the present invention, this area
All other embodiments that those of ordinary skill is obtained under not making creative work premise, broadly fall into present invention protection
Scope.
Refer to Fig. 1, a kind of reality filtering the technique of fiber grain in transformer oil that the embodiment of the present invention provides
Execute example to include:
101, transformer oil and normal hexane reagent are mixed into mixture liquid according to preset volume ratio.
102, described mixture liquid is joined in defecator filter.
103, the fiber grain in the described transformer oil after filtering is obtained.
Above-mentioned is that provide the present invention a kind of filters the step of the technique of fiber grain in transformer oil and carry out detailed
Describe, detailed process will be described in detail below, refer to Fig. 2, a kind of filtration transformator that the embodiment of the present invention provides
In oil, another embodiment of the technique of fiber grain includes:
201, transformer oil and normal hexane reagent are mixed into mixture liquid according to the volume ratio of 1:4；
In the present embodiment, transformer oil mixes according to the volume ratio of 1:4 with normal hexane, through experiment repeatedly,
Find that the oil of same volume filters after processing again, about 3 hours can be shortened compared to untreated situation
Time, substantially increase efficiency；Additionally under 1:4 ratio, filtration fastest, efficiency is the highest；And normal hexane will not be with
Fiber grain reacts.
202, mixture liquid is joined defecator carries out the filtration of three phases, sequentially pass through three different mesh
The screen cloth of number filters；
In the present embodiment, the screen cloth of three different meshes can filter out the fiber grain of different-grain diameter size, with convenient
Fiber grain is studied.
203, fiber grain from the screening of three different meshes online transformer oil obtained after filtering.
Above-mentioned is that provide the present invention a kind of filters the technique of fiber grain in transformer oil and retouch the most in detail
State, below will with an application process, present invention is described, refer to Fig. 3, Fig. 4 (a), Fig. 4 (b) and Fig. 4 (c), the present invention
There is provided a kind of filter the application examples of the technique of fiber grain in transformer oil and includes:
By needing the transformer oil filtered to mix according to the ratio of volume 1:4 with normal hexane, stir, then pour funnel into
Filter in 2, find to filter the transformer oil of same volume, find to filter again, compared to not locating after processing
The situation of reason can shorten the time of about 3 hours, and vacuum pump 11 can not have because of the overheated stall that works time long
Problem.If insulating oil and normal hexane are according to other proportional arrangement, it is possible to shorten filtration time, but under the ratio of 1:4, mistake
Filter shortest time, efficiency is the highest.
Referring to Fig. 3, defecator is mainly by funnel 2, and is arranged on the screen cloth group of interior three different meshes of funnel 2
Become, the screen cloth of different meshes, the fibrous particle that size is different can be filtrated to get；Transformer oil and normal hexane are with 1:4's
After volume ratio mixes, the time decreasing filtration makes the working time of vacuum pump 11 also reduce, it is ensured that vacuum pump
The normal work of 11.
The above, above example only a kind of filters fiber grain in transformer oil in order to illustrate that the present invention provides
Process technology scheme, is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, this area
Those of ordinary skill is it is understood that the technical scheme described in foregoing embodiments still can be modified by it or right
Wherein portion of techniques feature carries out equivalent；And these amendments or replacement, do not make the essence disengaging of appropriate technical solution
The spirit and scope of various embodiments of the present invention technical scheme.
