Description
Technical field
The present invention relates to the tool of network communication technology, database software and Computer Control Technology in terms of transformer test
A kind of body application, and in particular to transformer test data acquisition processing system.
Background technique
At present in transformer test preliminary preparation, generally by technical staff's Design of Transformer testing program.And
When Design of Transformer testing program, transformer test standard, design of transformer value and transformer according to relevant voltage grade are used
Family technical protocol needs to take considerable time calculate repeatedly with energy and checks evaluation, could finally provide a set of reasonable
Testing program.Designing unreasonable testing program, to directly result in transformer test data untrue, or even is difficult to reflect transformation
Device designing quality and service life.
In addition, the transformer test measurement method that transformer production producer generally uses is: doing which kind of instrument which kind of tests
Device, and test data is manually recorded on paper or in measuring instrument, existing transformer test data processing method be mostly by
Collected test data handles manually offline, then is compared with standard value and design value, whether judges this test data
Meet the mode of design requirement and standard criterion, but this data processing method real-time is poor, low efficiency cannot timely and effective place
Test data is managed, analysis transformer whether there is problem.Even if as partial discharge, temperature rise, it is long when unloaded, lightning impulse can online into
The test of row Test Data Collecting processing, there is also experimental data processing ability is poor and sharing difference disadvantage.Work as test data
When abnormal, the test situation of related technical personnel's current transformer cannot be informed in time, take measures to handle transformer event as early as possible
Barrier.For experimental technique personnel, since every Transformer Plant Test project kind is various, the test period is long, tests number
Big according to amount, the professional skill of technical staff is variant, along with experimental data processing personnel are different from test operator, can make
Missing is omitted at transformer test data record, processing lag, accident analysis is not in place, the problem of sharing difference, thus
Cause to be difficult to find transformer fault type and reason in time, user's prison makes representative and checks test data difficulty, or even influences to become
Production, factory and the time of delivery of depressor and production efficiency various aspects problem.
For test report writes personnel, similarly, since every transformer all include routine test, type approval test,
Special test, pilot project is various, and test data amount is big, and data and curves and table are more, and the transformer test data preparation period is short
The characteristics of, it in turn results in transformer test report and compiles and edit that task is tight, and the period is long, wrong careless mistake, transformer time of delivery easily occur
It is long, waste technical staff's extensive work matter of time.The test report achieved in paper form will cause and consult history transformer
Test data is very difficult, and transformer production test process trackability is poor, is especially to look at the production of same model different time
Transformer test data the problem of.
Summary of the invention
