串聯(lián)諧振英文翻譯

DAXZ series variable frequency cascade resonance test device is applicable to the high voltage withstand test of large capacity，high voltage capacitive insulating tested instruments，such as electric generator，power transformer，high voltage cross-linking cable，voltage and current transformer，casing pipe and so on .Device voltage and capacity can be customized according to users’ needs. Variable frequency cascade resonance test device adopts the principle of LC cascade resonance. By changing the output frequency，cascade resonance occurs between the reactor inductance L and tested instrument capacitance C in the loop circuit. Resonant voltage is the voltage on the tested instrument. FS series variable frequency cascade resonance test device meets the requirements of DL/T 849.6-2004 "high voltage resonance test device"

DAXZ系列變頻串聯(lián)諧振試驗(yàn)裝置適用于大容量、高電壓電容式絕緣測試儀器，如發(fā)電機(jī)、電力變壓器、高壓交聯(lián)電纜、電壓、電流互感器、套管等的高耐壓試驗(yàn)裝置，可根據(jù)用戶需要定制電壓和容量。變頻串聯(lián)諧振試驗(yàn)裝置采用了串聯(lián)諧振的原理。通過改變輸出頻率，在回路電路中的電抗器電感L和測試的儀器電容C之間發(fā)生級聯(lián)共振。諧振電壓是測試儀器上的電壓。DAXZ系列變頻串聯(lián)諧振試驗(yàn)裝置符合DL/T 849.6-2004“高電壓諧振試驗(yàn)裝置的要求”

調(diào)頻串聯(lián)諧振試驗(yàn)裝置主要功能和特點(diǎn) 

1、 High reliability.  The system adopts imported power components as the core of power conversion. The output voltage and frequency output is stable；electromagnetic compatibility is designed reasonably，and protection function is perfect. After several times short circuit tests of high voltage to ground, the system remains intact. and the system has strong ability of overload.

2、 Strong automatic tuning function. When it tunes automatically，the system will sweep from 30Hz to 300Hz automatically, display swept frequency curve，which users can watch intuitively. After sweeping，the system will find the resonant frequency point initially according to the swept frequency ，and then within the range of ± 5Hz and taking the resolution of 0.01Hz，it will sweep the frequency carefully，and finally pinpoint the resonant frequency.    

3、 Support multiple test patterns. The system supports the test modes "automatic tuning + manual voltage regulation ", "automatic tuning and automatic voltage regulation", "manual tuning and manual voltage regulation"and so on. The mode of "automatic tuning + manual voltage regulation" is recommended. It can find the resonance point quickly, and control the test process by manual adjustment of voltage，which is safer.    

4、 The system has friendly man-machine interface. Test parameters，test control and test results can display on the screen, intuitive and clear, and it has the function of automatic timing and operation indication. Touching screen operation and display；It can also store and query data.    

5、 Perfect protection function.  It has the function of zero protection (if the voltage output control knob is not at zero, the system is prohibited to boot), over-voltage protection, over-current protection, flashover protection and so on，which ensures the reliability of the system.
