"<p>在物理学中,功率是完成工作的速度。它等于每单位时间消耗的能量。功率单位为<strong>每秒焦耳[J/s]</strong>,也称为<strong>瓦特[W]</strong>。功率随时间的积分定义了能量(完成的功)。通过电压乘以电流来计算电气系统的功率。</p>" }, { "question": "测量直流和交流功率有什么区别?", "answer": "<p><br />测量直流功率并不复杂,因为电压和电流是恒定的,因此没有频率,积分的时间间隔仅定义了功率计算的平均间隔。为了测量交流系统,需要知道周期时间。由于电网频率根据该确切时刻的能量供应和电力负载的平衡而不断变化的事实,不能通过将正常电网频率(例如50Hz)作为常数来完成。</p>" }, { "question": "传统型和Dewesoft的功率分析仪有什么区别?", "answer": "<p>传统的功率分析仪使用零点检测来确定周期时间。这意味着他们评估电压或电流何时越过该x轴,并使用该值来计算周期时间。另一方面,Dewesoft 功率分析仪使用特殊的FFT算法(软件PPL)来确定周期性时间(频率)。该算法使用多个周期的采样窗口,通过特殊的FFT算法确定信号的周期时间。计算出的频率非常准确(mHz),适用于每种应用(电机,逆变器,电网等)。</p>" }, { "question": "Dewesoft如何计算交流系统的功率?", "answer": "<p>Dewesoft在频域中计算功率。在预定的时间段内,对电压和电流进行了FFT分析,确定了一定数量的周期(对于电气应用,通常为10个周期)和确定的采样率。 FFT得到每个谐波的电压,电流和cos phi的幅度。这种FFT转换的一个主要好处是,现在可以校正整个频率范围内的放大器,电流或电压传感器在幅度和相位上的行为(使用Sensor XML)。</p>" }, { "question": "Dewesoft电力模块提供哪些布线图?", "answer": "<p>Dewesoft功率分析仪可以测量DC,单相,2相,3相以及6至12相特殊测量。Dewesoft X软件中,DC、单相、2相和各种3相都有预定义的测量配置可供选择(星形,三角洲,Aron,V型连接,3相2米),对于更高的相位,可以使用多单相电力模块测量,并使用数学模块将总和相加。</p>" }, { "question": "测量逆变器需要准备什么?", "answer": "<p>测量逆变器时,请始终使用高速放大器,因为电压会以高达几百kHz的开关频率进行调制,还应确保使用具有高带宽能力的电流传感器,并确保它们能够测量直流和交流电流。不要忘记将频率源设置为电流,并使用星形或三角形连接。切勿使用Aron或V型接头进行此类测量。</p>" }, { "question": "Dewesoft功率分析仪是否适合电动汽车测量?<br>", "answer": "<p>Dewesoft模块化测试系统与其功能强大的Dewesoft X软件和功率分析结合使用,可以测量所有类型的应用场景,对于电动汽车,Dewesoft电力测试捆绑包也得到了广泛使用。例如,可以使用6个单相电力模块并计算模块中的总功率来测量6相电动机。 .</p>" }, { "question": "Dewesoft 电量分析仪支持哪些电流传感器?", "answer":

MCTS2)。</p>" }, { "question": "鉴于数据量很大,我有哪些存储选项?", "answer": "<p class=\"p1\">由于计算量大且功能强大,记录的数据文件可能会变得相当庞大。幸运的是,DewesoftX 可根据您的具体应用需求提供多种存储选项:</p>\n<ul>\n <li class=\"p3\"><b>多文件存储</b></li>\n <li
