Description
Technical Field
The invention relates to the technical field of transformers, in particular to a respirator based on transformer application.
Background
A Chinese transformer oil storage breather is an important safety protection device of power transmission equipment, and is installed at the tail end of a pipeline which is communicated with air and arranged in a transformer oil storage cabinet. When the oil temperature of the transformer rises, the oil level of the oil storage cabinet rises correspondingly, so that the gas in the capsule is discharged through the respirator; on the contrary, when the temperature of the transformer is reduced, the oil level of the oil storage cabinet is also correspondingly reduced, and the capsule sucks part of gas through the respirator. Changing main transformer respirator silica gel is one of the integration project that the maintenance is regularly maintained, for the dielectric strength who guarantees transformer oil, when the silica gel discolours in the main transformer respirator and reaches silica gel total amount 2/3, need follow the change.
At present when changing with the silica gel in the respirator, need get off the respirator is whole to be dismantled, it is comparatively troublesome to in-process changing with silica gel, mix together the silica gel that discolours and the silica gel that does not discolour easily, can generally with the respirator in whole silica gel with change, cause the waste of 1/3 silica gel that does not discolour.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a respirator based on transformer application, which does not need to replace uncolored silica gel when replacing the silica gel in the respirator, and improves the replacement efficiency of the silica gel.
The invention is realized by the following technical scheme:
a breather based on transformer application comprises an upper cover, a cylinder body used for storing silica gel particles, a cylinder bottom and an oil cup, wherein the upper cover is connected with one end of the cylinder body through threads, the cylinder bottom is welded in the other end of the cylinder body, the inside of the cylinder body is in a sealing state, the oil cup is connected with the cylinder bottom through threads, a first disc and a second disc are arranged in the cylinder body, the circumferential outer wall of the first disc is fixed on the inner wall of the cylinder body, the second disc is positioned above the first disc, the second disc can move along the axial direction of the cylinder body and can rotate around the axial direction of the cylinder body, the first disc and the second disc are of the same structure, the first disc is provided with a plurality of through holes, the diameter of the through holes is larger than that of the silica gel particles, the through holes are distributed in an array manner along the circle center of the first disc, the first disc is also provided with a plurality of air holes, and, still be equipped with the dwang in the barrel, the dwang is vertical to run through in the oil cup stretches into to the barrel to the dwang is connected with the second disc, and the dwang can remove along barrel axial direction, and the dwang can also rotate round the axial of barrel.
In the technical scheme, when the silica gel particle separating device runs normally, the first disc is contacted with the second disc, and the through holes in the first disc are staggered with the through holes in the second disc, namely, the through holes in the first disc are aligned with the air holes in the second disc, and the air holes in the first disc are aligned with the through holes in the second disc, so that silica gel particles cannot fall downwards through the first disc and the second disc, and the normal work of the silica gel particles is ensured; when the silica gel grain is changed color from bottom to top, and when the silica gel grain changes color and reaches total silica gel amount 2/3, utilize the rotatory second disc of dwang, make through-hole on the second disc and the through-hole on the first disc align, the silica gel grain that is located on the second disc drops through the through-hole this moment, because the silica gel grain changes color by lower supreme gradual change of color, therefore, after 2/3's silica gel that discolours passes through first disc, rotate the second disc once more, prevent silica gel from continuing to drop down, can effectively separate the silica gel that discolours and the silica gel that does not discolour through setting up first disc and second disc, only need follow the silica gel that changes color, remain the silica gel that does not discolour, continue to use, thereby effectively reduced the quantity of following the silica gel that changes each time, and saved the cost.
Further, still be equipped with the guide bar in the barrel, guide bar one end runs through the upper cover, and the oil cup is run through to the other end, the dwang cover is on the guide bar to the dwang can move along the outer wall direction of guide bar.
