| 摘 要： | 主要研究背景为电力系统中配电柜体内温度检测与自动调节，系统供电若采用外部电源比如锂电池，由于配电柜开关设备的主回路中产生的焦尔热会使电池温度升高，大大减少电池的寿命，需要工作人员经常更换电池。因此提出了利用感应配电柜电流产生的电动势给整个系统供电的方案，重点研究了电流互感器的原理及电路设计。实验表明，采用这种方法可以很好的保证系统运行的可靠性和安全性。

| Abstract: | The main research background of the design is the temperature measuring of power distribution cabinet body and auto- matic adjustment in power system. The scheme of electric potential generated by the induction current distribution cabinet to the whole power system is put forward, and it focuses on the design principle and circuit of current transformer. Experiments show that this meth- od can be used with very good reliability and safety to assure the system operation. |
