The electrical equipment that Force system is crucial, electrical test seems abnormal important.
According to the old and new's standard-required of China's electric power code, the every examination before current transformer is installed or after replacing winding
Test the pilot project being all to detect.For the installation matter of the most objective kinetic current transformer body in field engineering
Amount, is allowed to meet application standard and correlation technique regulation, and it is qualified that secondary staff must examine and determine its various parameters, it is ensured that survey
The accuracy of amount, reliability.
The deficiency that at present on-site current transformer (CT) test exists has these points:
1) human-computer interaction interface operation inconvenience, there is limitation in system, algorithm.
On-the-spot CT tester is typically all the modes of operation such as touch screen, or roller, depends on its own system support completely, it is impossible to
Realize operation flexibly and data process and analytical calculation.
2) retardance of time, " data " (finger to finger test personnel, pilot project, testing equipment parameter, are joined by testing equipment
Number, test period, test data etc.) unreliability, imperfection.
On-the-spot application CT assay device uses embedded LCDs, is only limitted to current device under current operating conditions
Running, it is impossible to include above-mentioned " data ", meanwhile, in process of the test, typically all testing crew is manually recorded or strip prints relevant
Test data, the formation of CT test report can complete after can only waiting end-of-job, thus be easily caused data distortion, during report
Extend.
3) data acquisition sampling point is accurate not, and interpretation of result error is bigger.
CT tester data acquisition sampling point precision is inadequate, and C-V characteristic is only trace-point method simultaneously so that data results exists
There is error to a certain extent.
4) anthropic factor weight relatively affects greatly.
In process of the test, the reading people from scene of data is used valuation record, loses test knot to a certain extent
The accuracy of fruit.
5) complete test report can not be formed.
The consideration test feature that CT test is the most simple is tested, it is impossible to meets user's actual need and meets technology rule
Complete test report.
In order to solve above-mentioned deficiency, this application system is independent operating under PC operating system, in satisfied on-the-spot different CT examinations
Testing " data " in instrument process of the test, in real time in input (or being automatically imported) this software, software utilizes relevant mathematical method pair
Sampled data carries out process of refinement, depicts smooth conic section.Then, bis-Equivalent Model of CT and mathematical analysis are utilized
Data are carried out processing and being calculated corresponding result of the test by method, and finally, software is according to fixing test report establishment mould
Plate forms complete test report.
