china is more by 35-110 kv transformer quantity at present, and electric power system provides qualified voltage for ensureing to society, can arrangement transfer the files according to local transformer-supplied load condition, thereby adjust voltage.Yet when the transformer time of putting into operation surpasses more than 2 years, because showing Kong Xianjun, gear adopts the mode of adding a cover polymethyl methacrylate, polymethyl methacrylate is being subject to, under the long-time irradiation of daylight ultraviolet ray, variable color to occur, and easily influenced by ambient temperature, shrink, cause gear demonstration inside, hole to advance dust, cause not seeing its content of Chu, and plexiglass cover have to be pried open.After repeatedly carrying out repeatedly, numerical value in it more and more difficulty is read, and now, for guaranteeing that the gear of adjusting can meet the advice note of transferring the files, just needs the survey gear to be calculated, and repeated multiple timesly just can guarantee it is qualified.The consuming time of this process will be more and more longer, and easily exceeding arranges to have a power failure transfers the files the time, thereby brings harmful effect to enterprise.
Summary of the invention
the utility model provides a kind of power transformer gear to show the hole dust guard, overcome the deficiency of above-mentioned prior art, it can effectively solve existing power transformer gear and show that inside, hole is difficult for seeing clearly, reading length consuming time, and the process of transferring the files easily exceeds the problem of the time of transferring the files that arranges to have a power failure.
the technical solution of the utility model realizes by following measures: a kind of power transformer gear shows the hole dust guard, comprise power transformer gear display device and dust guard, be distributed with gear on the power transformer gear display device and show hole, dust guard comprises tube connector and dust cap, the gear demonstration is fixed with tube connector on hole, is installed with dust cap on tube connector.
below the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned gear shows that hole can be stepped hole, and the bottom of tube connector is positioned at the upper inner that gear shows hole, and the lower end seat of tube connector shows the step upper end in hole in gear.
above-mentioned gear shows that the lower inner part in hole can be oval hole shape.
the bottom of above-mentioned tube connector and gear show that hole can be fixedly installed togather by fluid sealant.
the top of above-mentioned tube connector is fixing can external thread column, and there is internal thread hole the inside of dust cap, and internal thread hole and external thread column are fixedly installed togather.
the lower outside of above-mentioned tube connector can be hexagon.
the outside of above-mentioned dust cap can be hexagon.
the utility model reasonable and compact in structure, easy to use, it by installing tube connector and dust cap outside the power transformer gear shows hole, can avoid sunlight to the direct projection of power transformer gear display device inside and entering of dust, just reading of numerical value in the inner, thereby improve reading and the efficiency of transferring the files, shorten the operating time that has a power failure and transfer the files.
The accompanying drawing explanation
accompanying drawing 1 is looked the half section structural representation for the master of the utility model most preferred embodiment.
accompanying drawing 2 is accompanying drawing 1 overlooks the broken section structural representation.
the local structure for amplifying schematic diagram that accompanying drawing 3 is A place in accompanying drawing 1.
the local structure for amplifying schematic diagram that accompanying drawing 4 is B place in accompanying drawing 2.
coding in accompanying drawing is respectively: 1 is the power transformer gear display device, and 2 for gear shows hole, and 3 is tube connector, and 4 is dust cap, and 5 is external thread column, and 6 is internal thread hole, and 7 is fluid sealant.
Embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete execution mode according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all to be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1 to 4, this power transformer gear shows that the hole dust guard comprises power transformer gear display device 1 and dust guard, be distributed with gear on power transformer gear display device 1 and show hole 2, dust guard comprises tube connector 3 and dust cap 4, the gear demonstration is fixed with tube connector 3 on hole 2, is installed with dust cap 4 on tube connector 3.Can avoid like this sunlight to the direct projection of power transformer gear display device 1 inside and entering of dust, just reading of numerical value in the inner; In use, dust cap 4 is opened, be can read gear and show the numerical value in hole 2, after reading, it is closed and gets final product.
can according to actual needs, to above-mentioned power transformer gear, show that the hole dust guard makes further optimization and/or improvements:
as shown in accompanying drawing 1 to 4, gear shows that hole 2 is stepped hole, and the bottom of tube connector 3 is positioned at the upper inner that gear shows hole 2, and the lower end seat of tube connector 3 shows the step upper end in hole 2 in gear.Stepped hole both can realize spacing to tube connector 3 also having good dust-proof effect.
as shown in accompanying drawing 1 to 4, gear shows that the lower inner part in hole 2 is oval hole shape.So not only can meet the numerical value shape, numerical value can be showed fully, also can reduce interior hole dimension simultaneously, reduce entering of dust.
