Abstract
The invention provides a diagnosis method for displaying faults of an oil chromatography by utilizing a visual coordinate graph. The diagnosis method comprises the steps as follows: using the three groups of codes of the ratio ranges of C2H2/C2H4, CH4/H2 and C2H4/C2H6 as horizontal and vertical coordinates, dividing the coordinate graph into multiple zones and filling the zones with different colors for representing various faults; setting a color scale reference chart at the right side of the coordinate graph to distinguish various faults by the same color method as the coordinate graph; inputting the values of C2H2, C2H4, CH4, H2 and C2H6 and calculating the ratios of C2H2/C2H4, CH4/H2 and C2H4/C2H6; obtaining the three groups of codes of the ratio ranges of C2H2/C2H4, CH4/H2 and C2H4/C2H6 by contrasting improved three-ratio method encoding rules or no-encoding three-ratio method encoding rules; and locating the current position by the codes obtained from the step 3, marking the current position on the coordinate graph by a small red point, observing and contrasting the zone in which the small red point is positioned with the color scale at the right side, thus drawing the fault conclusion. The diagnosis method can overcome the defect that the fault type of oil-filled equipment can not be displayed visually by the existing method.
Description
Technical field
The present invention relates to the method for a kind of transformer technology field fault detect, particularly a kind of coordinate directly perceived diagram of can utilizing shows the oil chromatography fault Diagnosis Method.
Background technology
Through after a large amount of practices; It is found that the fault diagnosis of oil-filled equipment can not only depend on the component concentration of oil dissolved gas, also should depend on the relative content of gas, so International Electrotechnical Commission (IEC) uses C2H2/C2H4; CH4/H2; The ratio of C2H4/C2H6 is judged the fault type of oil-filled equipment, is called the improvement three-ratio method, and its coding rule and fault category determination methods are following:
Improvement three-ratio method coding rule:
Improvement three-ratio method fault type determination methods:
But because the fault type that the improvement three-ratio method can not all oil-filled equipments of limit does not have coding ratioing technigue and its additional each other application so adopt, its coding rule and fault category determination methods are following:
There is not coding ratioing technigue nature of trouble analysis and diagnosis method:
| Nature of trouble | C2H2/C2H4 | C2H4/C2H6 | CH4/H2 |
| Cryogenic overheating | ＜0.1 | ＜1 | Irrelevant |
| Middle temperature is overheated | ＜0.1 | 1＜ratio＜3 | Irrelevant |
| Hyperthermia and superheating | ＜0.1 | ＞3 | Irrelevant |
| High-energy discharge | 0.1＜ratio＜3 | Irrelevant | ＜1 |
| High-energy discharge is held concurrently overheated | 0.1＜ratio＜3 | Irrelevant | ＞1 |
| Low-yield discharge | ＞3 | Irrelevant | ＜1 |
| It is overheated that low-yield discharge is held concurrently | ＞3 | Irrelevant | ＞1 |
Though more than two kinds of methods can judge the various fault types of oil-filled equipment well; But its expression is directly perceived inadequately, three correlative values of utilizing gas is also arranged as coordinate axis in the practice, a kind of spatial coordinate graphic interpretation of foundation; Perhaps adopt triangle coordinate graphic interpretation to come whether fault of auxiliary judgment equipment; But these methods can only be used by the professional, its account form and actual graphic technique more complicated, and the operation maintenance personnel of transformer station reach and do not possess such professional knowledge; So need a kind of method intuitively to demonstrate the fault type of oil-filled equipment, the operation maintenance personnel can be come into plain view to the fault state of oil-filled equipment.
Summary of the invention
The technical matters that the present invention will solve has been to provide a kind of and can have changed the utilization coordinate diagram directly perceived demonstration oil chromatography fault Diagnosis Method that existing method can't intuitively show the defective of oil-filled equipment fault type.
The technical matters that the present invention will solve is achieved in that
A kind of coordinate directly perceived diagram of utilizing shows the oil chromatography fault Diagnosis Method, it is characterized in that: may further comprise the steps:
Step 3, contrast improvement three-ratio method coding rule does not perhaps have coding three-ratio method coding rule, draws three group codings of the ratio range of C2H2/C2H4, CH4/H2 and C2H4/C2H6;
Step 4, the coding that obtains with above-mentioned steps 3 location current location, and with dots in red on coordinate diagram, mark out above-mentioned position;
Step 5, the colour code of observing contrast dots in red region and the right contrasts, get final product the conclusion that is out of order.
When adopting improvement three-ratio method coding rule, said step 1 can be refined as: elder generation is divided into 27 zones with the coding of the ratio range of C2H2/C2H4, CH4/H2 and C2H4/C2H6 with seat figure; Again fault of the same race is filled above-mentioned 27 zones with color of the same race, different faults with different colours.
When adopting nothing coding three-ratio method coding rule, said step 1 can be refined as: use C2H2/C2H4 to set up coordinate diagram as horizontal ordinate, CH4/H2 and C2H4/C2H6 as ordinate earlier; Again coordinate diagram is divided into 9 zones, and fills above-mentioned zone with different colours; Said step 3 can be refined as: whether judge C2H2/C2H4 < 0.1; If, then calculate the value of C2H4/>C2H6, and be horizontal ordinate with C2H2/C2H4, with C2H4/C2H6 ordinate location current location; If not, then calculating the value of CH4/H2, and be horizontal ordinate with C2H2/C2H4, is ordinate location current location with CH4/H2.
The present invention has overcome the shortcoming that prior art can't intuitively show the oil-filled equipment fault type, makes the operation maintenance personnel of transformer station can in time grasp the fault type of current oil-filled equipment, minimizing accident occurrence probability intuitively.
