[艾尔电气 变压器绕组测试仪 产品简介]
绕组变形测试仪，用于测试6kV及以上电压等级电力变压器及其它特殊用途的变压器。电力变压器在运行或者运输过程中不可避免地要遭受各种故障短路电流的冲击或者物理撞击，在短路电流产生的强大电动力作用下，变压器绕组可能失去稳定性，导致局部扭曲、鼓包或移位等变形现象，这样将严重影响变压器的安全运行。采用频率响应分析法测量变压器的绕组变形，是通过检测变压器各个绕组的幅频响应特性，并对检测结果进行纵向或横向比较，根据幅频响应特性的变化程度，判断变压器绕组可能发生的变形情况。
别名：变压器绕组测试、绕组测试仪、绕组变形测试仪、绕组测试等等。

AL102 Transformer loop transform tester
Implementation of standards.
DL/T911－2004
Function and characteristics:
Transformer loop transform tester is international ascend most the forerunner's method frequency respond to analysis method(FRA) to carry on a test, is a kind of diagraph transformer to round a set of frequency to respond to of high and intelligent degree test instrument.
The system constitute: The transformer rounds a set to transform a test instrument from measure part and analysis software part constitute, measure part born from the signal and the signal diagraph constitute of black box son, analyze part is complete by the notebook, measure part and notebook to pass an USB conjunction. Main technique characteristics:
Have the in keeping with built-in applied BIOS system of independent intelligent property right, the achievement consume small, make hardware system very of stability, very in keeping with bad of experiment environment.
The integral whole which has an independent intelligent property right turns main plank and gather signal occurrence, data to collect and the data processing deliver at the integral whole, can promise the credibility of host height.
The adoption makes according to the technique of TCP/IP network agreement instrument usage in brief dependable, deliver a data quickly, match with fast Chi ambulation technique chip and 10/100 Ms from orientation notebook, measure time is short. The test equipment provided with USB to connect in the meantime and make test equipment and notebook link very convenient.
Measure importation signal Vi and output signal Vo in the meantime, and with the Vo/Vi come to token to round the Pin of set ring characteristic, thoroughly remove in order to scanning electric voltage signal range unsteady result in of diagraph error margin.
Adopt the fast Fu signs a leaf transformation FFT and numeral to filter a technique to carry on preparing a processing to the signal Vi and the Vo and biggest strengthenned the anti- interference of the test system function;
Development of according to collect of Windows2000/XP operate system with analysis system software, make the parameter establish, the data collect, the document keep, the sketch analyze and the report output etc. operate to in brief and easily go, data management with proficiency.
Main technique parameter
Instrument from take a passage DDS signal to output conduct and actions to sweep encourage of Pin signal; The signal outputs for the sine wave, the most significant+5 Vs, the signal outputs the resistance as 50 Ωs.
The signal outputs to measure scope:1K-1MHZ
The signal outputs a way: Adopt software to automatically control exportation, the adoption line form distribute of sweep Pin diagraph a method
Signal frequency accuracy: The signal source outputs the frequency degree of sine signal to be no bigger than 0.01%
The signal converts parts of technique index signs
Two high speed measure passage
The biggest importation signal is:+25 Vs(many files automatically regulate quantity a distance)
The AD amount of conversion turns accuracy:12
Measure the biggest static state error margin:0.5%
Collect passage exportation resistance:1 M Ω
Each time passage the tallest sample rate:20Msps
Each time passage the tallest greatly saving capacity:The 60 K kind order
