是的。下面是电流互感器的详细说明:
定义:
UR8LH电流互感器将一次电路的大电流直接转换为二次电路的小电流，为测量仪器、仪表、继电保护等类似电器供电。
它根据电磁感应原理工作，将一次侧的大电流转换成二次侧的小电流进行测量。
结构组成:
UR8LH电流互感器由封闭铁芯和绕组组成。
初级侧绕组的匝数非常小，串在需要测量电流的线路上，因此经常有整个线路的电流流过。
二次绕组匝数比较大，在测量仪和保护回路中串联。
初级线圈在主电路中连接，初级线圈必须与初级线路电压对地绝缘，以保证次级电路和人身的安全。
它是如何工作的:
UR8LH电流互感器的工作原理是磁感应。当外部电流通过初级绕组时，产生磁场，磁场诱导磁芯产生磁感应电动势。这个磁感应电动势就是电流互感器输出的电流。
变压器的转换率(即一次电流与二次电流的比值)可以通过调节磁芯的匝数和线圈的匝数来调节。

Yes. The following is a detailed explanation of the current transformer:
Definition:
UR8LH current transformer converts the large current of the primary circuit directly to the small current of the secondary circuit to supply measuring instruments, meters, relay protection and other similar electrical appliances.
It works according to the principle of electromagnetic induction, converting the large current on the primary side into a small current on the secondary side to measure.
Structure composition:
The UR8LH current transformer consists of a closed core and winding.
The number of turns on the primary side winding is very small and is strung in the line where the current needs to be measured, so there is often the entire current of the line flowing through.
The number of turns of the secondary winding is relatively large, which is connected in series in the measuring instrument and the protection loop.
The primary coil is connected in the main circuit, and the primary coil must be insulated with the primary line voltage to the ground to ensure the safety of the secondary circuit and the person.
How it works:
The UR8LH current transformer operates on the principle of magnetic induction. When the external current passes through the primary winding, a magnetic field is generated, and the magnetic field induces the magnetic core to generate a magnetic induced electromotive force. This magnetic induced electromotive force is the current output by the current transformer.
The transformer conversion ratio (that is, the ratio of the primary current to the secondary current) can be adjusted by adjusting the number of turns of the magnetic core and the number of turns of the coil.
