The attenuators and the sensitivity of detectors are calibrated in varied frequencies. the attenuation of the cable is also calibrated
對晶體檢波器在不同頻率下的礦靈敏度進行了測定;對同軸信號線的衰減量瓣行了標定。When this fault is cutted off and the breaker is reclosed, this scheme ca n ' t start by mistake. the availability of this scheme is proved with matlab test. the single phase high - impedance grounding fault is settled properly
Matlab模擬分析證明了該方案耐受過渡電阻的能力強,在故障切除和重合閘時不會因出現的暫態信號而誤啟動,不受系統振蕩、頻率偏差的影響,克服了常規保護靈敏度不足的缺點,較好地解決了單相高阻接地故障的難題。In the course of theory analyses, acoustic / vibration signal acts on the coupling area of a coupler. there are two different actions - horizontal operation and vertical operation and two different transmissions - traveling wave and standing wave. the responses of the sensor analyzed with matlab shows that the length of coupling and the frequency of acoustic / vibration signal will influence the sensitivity of the sensor
理論分析過程中,聲振動信號對傳感器的耦合區有不同作用方式(橫向作用縱向作用)以及不同傳播形式(駐波傳播/行波傳播) ,用數學軟體matlab對其響應進行模擬分析,得出了耦合長度和聲振動信號頻率會影響傳感器的靈敏度。That extremely promotes the development of the receiver. also the requirement of receiver becomes more rigorous. as the name implies, receiver need to improve the linearity, to reduce the distortions rate and bit error rate, and to expend the dynamic range, of course should ensure the signal detect capability precondition
這些要求同樣也促進了中頻接收機的不斷進步,要求其在保證信號檢測能力(即極高的靈敏度)的前提下:盡可能的提高接收機的線性度,使信號失真最小、誤碼率最低;盡可能的展寬接收機的動態范圍,使接收機的適應度更大、抗干擾能力更強。Because of the good sensibility, ultrasonic narrow band signal analysis technique with 1mhz central frequency was chosen to differentiate the heat treatment samples above - mentioned. there are obvious differences among heat treatment products in principal frequency, spectral peak ' s quantity, amplitude and distribution. that is to say, the technique of ultrasonic narrow band power spectral can be applied to characterize the microstructures of multi - phased alloy steels
利用窄帶信號頻譜分析技術靈敏度高的突出優點,選取中心頻率為1mhz的窄帶超聲信號,對上述不同熱處理試樣進行超聲功率譜分析,發現不同熱處理產物在功率譜主頻率、譜峰特徵(幅度、數量、分佈)等方面,都存在不同程度的差異。分享友人
