[艾爾電氣 變壓器繞組測試儀 產品簡介]
繞組變形測試儀，用于測試6kV及以上電壓等級電力變壓器及其它特殊用途的變壓器。電力變壓器在運行或者運輸過程中不可避免地要遭受各種故障短路電流的沖擊或者物理撞擊，在短路電流產生的強大電動力作用下，變壓器繞組可能失去穩定性，導致局部扭曲、鼓包或移位等變形現象，這樣將嚴重影響變壓器的安全運行。采用頻率響應分析法測量變壓器的繞組變形，是通過檢測變壓器各個繞組的幅頻響應特性，并對檢測結果進行縱向或橫向比較，根據幅頻響應特性的變化程度，判斷變壓器繞組可能發生的變形情況。
別名：變壓器繞組測試、繞組測試儀、繞組變形測試儀、繞組測試等等。

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
Sample the Vittal original package machine box
