Further, the solid impurity filter is mounted on the frame plate by anchor ear.
The beneficial effects of the utility model are: realizing online degasification, water removal to transformer oil using the present apparatus, except living together
Reason, without shutting down transformer, ensure that work continuity, and by after transformer oil Hand scarf, wirelessly replace fresh oil, also save
About cost.
Detailed description of the invention
Fig. 1 is the structure chart of transformer oil electrified maintenance device provided by the embodiment of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
In order to illustrate technical solution described in the utility model, the following is a description of specific embodiments.
Fig. 1 shows the structure of transformer oil electrified maintenance device provided by the embodiment of the utility model, for the ease of saying
It is bright to illustrate only part relevant to the utility model embodiment.
As shown in Figure 1, transformer oil electrified maintenance device provided in this embodiment includes pedestal 1, it is fixed on the pedestal 1
There is frame plate 2, solid impurity filter 3 and pneumatic filter 4 are installed on the frame plate 2, oil storage barrel is installed on the pedestal 1
5, temporary storage barrel 6 and water-oil separating centrifuge 7, the pneumatic filter 4 include hermetically sealed can 41, and described 41 one end of hermetically sealed can is oil inlet
Pipe, the other end is flowline, there is degassing net 42 in the hermetically sealed can 41, and 42 inner wall of degassing net has circle degassing film 43,
The oil inlet pipe and flowline stretch in degassing net 42, and there are also exhaust tube 44, the flowlines for 41 side wall of hermetically sealed can
Bottom end is connected to the water-oil separating centrifuge 7 by connecting tube, and 7 bottom of water-oil separating centrifuge is connected by oil exit pipe
To the temporary storage barrel 6, the arrival end of the solid impurity filter 3 is connected to inside the temporary storage barrel 6 by oil way flexible pipe, institute
