第一电容器和第二电容器分别被设计为第一变容二极管和第二变容二极管。
The first capacitor and the second capacitor are designed as a first varactor and as a second varactor, respectively.
第二部分是光纤传输和光电转换器，从传感头输出的频率调制信号驱动装在高压端的发光二极管，进而转换成光脉冲信号；
The first one is a sensor head converting the current flowing in the power line into the optical pulse FM signal. The second one is optical fiber transmission and optolectric conversion.
用于第一开关和第二开关中的每一个的相关联的反并联二极管，其配置成当与该二极管相关联的开关无效时，提供电通路；
For each of the first and second switches, an associated anti-parallel diode is configured to provide an electrical path when the switch associated with the diode is inactive.
巡查方式：第二开关上的发光二极管会发作100流明的电池节能方式，将持续权利高达44小时；
Patrol mode: second switch-on, the LEDs will produce 100 lumens in battery power saving mode which will continuously work upto 44 hours ;
巡查方式：第二开关上的发光二极管会发作100流明的电池节能方式，将持续权利高达44小时；
Patrol mode: second switch-on, the LEDs will produce 100 lumens in battery power saving mode which will continuously work upto 44 hours ;
