| 电容电感测试仪工作原理 Working principle of capacitance and inductance tester 全自动电容电感测试仪采用桥式电路结构，标准电容器和被试电容器作为桥式电路的两臂。当进行电容器电容值测量时，合上测试开关K，测试电压同时施加在标准电容器和被试电容器上，处理器通过传感器同采集流过两者的电流信号并进行处理后得也被试电容器的电容值和阻性分量。 Full automatic capacitance and inductance tester adopts bridge circuit structure, standard capacitor and tested electric container are two arms of bridge circuit. When measuring the capacitance value of the capacitor, close the test switch K, and the test voltage is applied to the standard capacitor and the tested capacitor at the same time. The processor collects the current signals flowing through both through the sensor and processes them to obtain the capacitance value and resistive component of the tested capacitor. 全自动电容电感测试仪由于采用标准电容器，被试电容器同步采样技术，可不受电源电压波动的影响；加之测量过程是全自动进行的，避免了手动操作引起的误差，因此具有稳定性好，重复性好，准确可靠的特点。 The full-automatic capacitance and inductance tester adopts the synchronous sampling technology of standard capacitor and tested electric container, which can not be affected by the fluctuation of power supply voltage; in addition, the measurement process is fully automatic, which avoids the error caused by manual operation, so it has the characteristics of good stability, good repeatability, accuracy and reliability. |
