是的。下面是電流互感器的詳細(xì)說明:
定義:
UR8LH電流互感器將一次電路的大電流直接轉(zhuǎn)換為二次電路的小電流，為測量儀器、儀表、繼電保護(hù)等類似電器供電。
它根據(jù)電磁感應(yīng)原理工作，將一次側(cè)的大電流轉(zhuǎn)換成二次側(cè)的小電流進(jìn)行測量。
結(jié)構(gòu)組成:
UR8LH電流互感器由封閉鐵芯和繞組組成。
初級側(cè)繞組的匝數(shù)非常小，串在需要測量電流的線路上，因此經(jīng)常有整個(gè)線路的電流流過。
二次繞組匝數(shù)比較大，在測量儀和保護(hù)回路中串聯(lián)。
初級線圈在主電路中連接，初級線圈必須與初級線路電壓對地絕緣，以保證次級電路和人身的安全。
它是如何工作的:
UR8LH電流互感器的工作原理是磁感應(yīng)。當(dāng)外部電流通過初級繞組時(shí)，產(chǎn)生磁場，磁場誘導(dǎo)磁芯產(chǎn)生磁感應(yīng)電動(dòng)勢。這個(gè)磁感應(yīng)電動(dòng)勢就是電流互感器輸出的電流。
變壓器的轉(zhuǎn)換率(即一次電流與二次電流的比值)可以通過調(diào)節(jié)磁芯的匝數(shù)和線圈的匝數(shù)來調(diào)節(jié)。

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.
