Method.
Background technology
Transformator is one of important electrical in power system, and it once breaks down, it will have serious consequences.
By the way of gas chromatography carries out constituent content analysis to Gases Dissolved in Transformer Oil, monitor transformator healthy
Operation conditions has been one of effective means of a kind of acknowledged guarantee transformer safety, stable operation.In recent years, for improving
The real-time monitoring level of high-power transformer and fault pre-alarming ability, in State Grid Corporation of China's system, Gases Dissolved in Transformer Oil is online
Monitoring device outfit rate presents a rapidly rising trend.But as a kind of emerging technology, Gases Dissolved in Transformer Oil on-line monitoring skill
Art and equipment quality are the most immature, effectively verify means owing to lacking, and large number quipments also exists the problems such as data accuracy is low,
Wrong report, misrepresenting deliberately and happen occasionally, working to transformer state evaluation and fault diagnosis brings new difficulty.Along with power transmission and transforming equipment
Carrying out in a deep going way of repair based on condition of component and appraisal, developing one can carry out level to chromatographic detection apparatus in electrical network system
Change appraisal procedure, it is ensured that Detection accuracy and the stability of transformer oil chromatographic on-Line Monitor Device are particularly important.
Summary of the invention
Patent of the present invention is to be solved technical problem is that proposition one can be to chromatographic detection apparatus in electrical network system
Carrying out stratification appraisal procedure, this method combines Comparability test, desk-top chromatograph by laboratory chromatographs, molten in transformer oil
Solve and between On-Line Monitor Device of Gas three, form stratification transmission of quantity value, solve Gases Dissolved in Transformer Oil on-line monitoring
The difficult problem that device cannot be traced to the source, may be implemented in line monitoring device detection data accurately, stable after put into operation, and improve online
When monitoring device real-time oversight transformator runs health status, the credibility of detection data.
For achieving the above object, the technical solution adopted in the present invention is:
Chromatographic detection apparatus stratification appraisal procedure in a kind of electrical network system, comprises the following steps:
(1) metrological service is sent to carry out measurement verification desk-top chromatograph；
(2) the desk-top chromatograph that measurement verification is qualified participates in chromatograph associating Comparability test calibrating；
(3) chromatograph of associating Comparability test assay approval is applied to the on-Line Monitor Device of Gases Dissolved in Transformer Oil；
(4) on-Line Monitor Device of described Gases Dissolved in Transformer Oil carry out an acceptance inspection in chromatograph checking experiment room qualified after install
To transformer station, the health status of transformator is exercised supervision.
Further, to step (1) and step (2) being examined and determine underproof desk-top chromatograph depot repair, the most again
Calibrating.
Further, the acceptance method in step (4) is: by drawing oil sample transformator, utilizes checking experiment room desk-top
Chromatograph and Gases Dissolved in Transformer Oil on-Line Monitor Device analyze same batch oil sample, if Gases Dissolved in Transformer Oil exists
The detection data chromatographic detection data desk-top with checking experiment room of line monitoring device keep consistent, then acceptance(check).
The present invention has the advantage that with good effect:
(1) patent of the present invention achieves chromatograph associating Comparability test, desk-top chromatograph, and Gases Dissolved in Transformer Oil is supervised online
Survey and between device three, form stratification transmission of quantity value；
(2) patent of the present invention effectively solves the difficult problem that Gases Dissolved in Transformer Oil on-Line Monitor Device cannot be traced to the source；
(3) patent of the present invention improves the on-Line Monitor Device Supervision Level to the health status of operating transformer, and improves electricity
Net safety and power supply reliability.
Accompanying drawing explanation
The flow chart of chromatographic detection apparatus stratification appraisal procedure in Fig. 1 electrical network of the present invention system.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the present invention is specifically described and illustrates:
The specific embodiments of chromatographic detection apparatus stratification appraisal procedure in a kind of electrical network system, by saving the verification of DianKeYuan chromatograph
Laboratory organizes multiple stage chromatograph associating Comparability test between a different experiments room every year regularly, evaluates the desk-top of participant
Chromatographic measurement accuracy, repeatability, it is considered that the data that the chromatograph of participation Comparability test is given are in certain deviation
In the range of, then it is assumed that assay approval, specifically can determine deviation model according to the requirement Stringency of chromatograph using area, environment
Enclosing, the desk-top chromatograph participating in chromatograph associating Comparability test need to be by the qualified instrument of metrological service of this province measurement verification, and metering is not
Qualified desk-top chromatograph is carrying out censorship again after need to returning maintenance；Participate in after chromatograph combines Comparability test undesirable
Desk-top chromatograph, need to find out the problem self existed or return factory and office's reason；Desk-top color qualified after participating in chromatograph associating Comparability test
Spectrometer, can carry out next step transmission of quantity value to Gases Dissolved in Transformer Oil on-Line Monitor Device.
Described Gases Dissolved in Transformer Oil on-Line Monitor Device need to carry out arrival in DianKeYuan chromatograph checking experiment room and test
After folding lattice, just may be mounted to transformer station and the healthy operation conditions of transformator is carried out day-to-day supervision；By transformator is taken oil
Sample, utilizes desk-top chromatograph and Gases Dissolved in Transformer Oil on-Line Monitor Device to analyze same batch oil sample, confirms transformation
The detection accuracy of device oil dissolved gas on-Line Monitor Device, if the detection of Gases Dissolved in Transformer Oil on-Line Monitor Device
Data detection chromatographic with lab bench data keep consistent, then show Gases Dissolved in Transformer Oil on-Line Monitor Device
Supervision to the healthy operation conditions of transformator has credibility.
