Abstract
A kind of transformer oil moisture measurement test paper, the scraps of paper are set to white rectangles structure, the rectangle scraps of paper are divided in the longitudinal direction upper and lower two regions, a side region scribble anhydrous slufuric acid copper powders, and another region is that white space does not smear any material.Whether the utility model is mainly used in measuring transformer oil containing moisture.The test paper scribbling anhydrous slufuric acid copper powders is put into transformer oil, if anhydrous slufuric acid copper powders becomes blueness, proves to contain moisture in transformer oil, if nondiscolouring, then show that transformer oil is not moisture.Whether this novel test paper related to is simple to operate, easy to carry, can not pollute transformer oil, can judge in transformer oil rapidly moisture in laboratory or scene.
Description
Technical field
Whether moisture the utility model relates to a kind of test paper, especially for test paper in measuring transformer oil.
Background technology
Transformer oil is through distillation, refining and a kind of mineral oil of obtaining in natural oil, the potpourri of to be lube cut in oil through acid-alkali refining process obtain pure stable, viscosity is little, good insulating, cooling are good liquid natural hydrocarbons.Good transformer oil should be clean and transparent liquid, must not have sediment, mechanical impurity suspension and flocculence material.If its contaminated and oxidation, and produce resin and sediment, transformer oil oil will be deteriorated, and color can gradually become light red, until become auburn liquid.When transformer has fault, the color of oil also can be made to change generally, just should not use again when transformer oil is light brown.In addition, transformer oil can show as muddy emulsus, oil colours blackout, obfuscation.The muddy emulsus of transformer oil, shows in oil containing moisture.Oil colours shades, and shows transformer oil insulation ag(e)ing.Oil colours turns black, and even has empyreumatic taste, shows that inside transformer has fault.
At present, the main moisture adopted in micro-water analyzer measuring transformer oil, the method measuring accuracy is higher, is mainly used in the content of the micro-water of Measurement accuracy transformer oil.Whether moisture for fast qualitative measuring transformer oil, the party's rule seems complicated, and efficiency is not high.
For the problems referred to above, this new design goes out a kind of simple test paper, and simply easy to operate, test paper can reuse, and has not only saved cost, has also improved detection efficiency.
Utility model content
Whether the purpose of this utility model is: contain this feature of moisture according in the transformer oil of long operational time, designs and is applicable to test paper that is on-the-spot and laboratory use, moisture for qualitatively judging in transformer oil.
The utility model realizes by following technical solution.
A kind of transformer oil moisture measurement test paper, the utility model feature is, the scraps of paper are set to white rectangles structure, the rectangle scraps of paper are divided in the longitudinal direction upper and lower two regions, one side region is provided with anhydrous slufuric acid copper powders on the scraps of paper, and opposite side region is that white space is not provided with any material on the scraps of paper.
The utility model is covered with the aperture of proper alignment in anhydrous cupric sulfate powder area being provided with, around this region, be provided with black surround mark, anhydrous slufuric acid copper powders is filled in aperture.
The utility model scraps of paper are made up of unwetted material.
Mechanism of the present utility model: working time, longer transformer oil was moisture; Anhydrous slufuric acid copper powders is met water and is become blueness; Transformer oil viscosity is little, arranges small structure, increases duration of contact and the contact area of oil and anhydrous cupric sulfate.
Whether the beneficial effects of the utility model are: this novel test paper related to is simple to operate, easy to carry, can not pollute transformer oil, can judge in transformer oil rapidly moisture in laboratory or scene.Meanwhile, after drying with the test paper crossed, reusable.Therefore, originally novel have beneficial effect with low cost, to improve detection efficiency.
The utility model content is set forth further below in conjunction with drawings and Examples.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.Wherein 1 is the scraps of paper, 2 black surround marks, and 3 is white space (not smearing any material), and 4 is aperture (filling anhydrous slufuric acid copper powders).
Embodiment
See accompanying drawing 1, a kind of transformer oil moisture measurement test paper, the utility model feature is, the scraps of paper 1 are set to white rectangles structure, the rectangle scraps of paper are divided in the longitudinal direction upper and lower two regions, one side region scribbles anhydrous slufuric acid copper powders, opposite side region is that white space 3 is not provided with any material.
The utility model is provided with the aperture 4 being covered with proper alignment in anhydrous cupric sulfate powder area, and around this region, be provided with black surround mark 2, anhydrous slufuric acid copper powders is filled in aperture 4.
The utility model scraps of paper are made up of unwetted material.
The method of operating of the utility model test paper is as follows:
(1) execute-in-place method
1, utilize special sampling instrument, transformer oil is taken out, puts into drying receptacle;
2, test paper being scribbled anhydrous cupric sulfate region immerses in oil samples, leaves standstill 1 minute;
3, test paper is taken out, observe in test paper black surround region whether have variable color;
4, test paper becomes blueness, and transformer oil is moisture, test paper nondiscolouring, and transformer oil is not moisture;
5, sample withdrawal is dried.
(2) laboratory operating method
1, transformer oil is put into drying receptacle;
2, test paper being scribbled anhydrous cupric sulfate region immerses in oil samples, leaves standstill 1 minute, or sets level test paper, utilize dropper oil samples to be dropped in test paper black surround;
3, observe in test paper black surround region whether have variable color;
4, test paper becomes blueness, and transformer oil is moisture, test paper nondiscolouring, and transformer oil is not moisture;
5, sample withdrawal is dried.
Claims (3)
1. a transformer oil moisture measurement test paper, it is characterized in that, the scraps of paper are set to white rectangles structure, the rectangle scraps of paper are divided in the longitudinal direction upper and lower two regions, one side region is provided with anhydrous slufuric acid copper powders on the scraps of paper, and another region is that white space does not smear any material on the scraps of paper.
2. a kind of transformer oil moisture measurement test paper according to claim 1, is characterized in that, being provided with the aperture being covered with proper alignment in anhydrous cupric sulfate powder area, around this region, be provided with black surround mark, anhydrous slufuric acid copper powders is filled in aperture.
