HRBFXZ系列变频串联谐振交流耐压高压试验装置 |
|
| |
对于任何一个电抗器（其电感为L）和电容器（其电容为C）组成的串联LC谐振电路而言，他都有一个固定的频率f=1/2π根号LC，当外加电源信号的频率等于这个频率时，该电路将发生谐振。谐振时，电感上及电容上获得的电压最大，而大多数的被试品都可以等效成一个电容器。基于这一思想，在串联谐振电路前提供一个调节频率又可调节电压的变频变压电源，在电容两端并联一个分压器作测量及反馈之用，这样就可构成该套装置。 |

For any reactor (inductance as L) and capacitors (the capacitor for
C) consisting of series LC resonant circuit, he has a fixed frequency
f = 1/2π radical LC, when the external power signal equal frequency
when the frequency of the resonant circuit will occur. Resonance,
the inductance and capacitance on the voltage on access to the largest,
and most of the sample can be equivalent to a capacitor. Based on
this idea, in the series resonant circuit to provide a voltage regulator
can adjust the frequency of the inverter transformer power supply,
in parallel at both ends of a capacitor voltage divider for the measurement
and feedback purposes, then this will constitute the set of devices.
