The electrician knowledge channel of the company has not been updated for a long time. Now it continues to share some basic knowledge provided by some engineers. I see that many customers always mention the wiring diagrams of some electrical appliances, and I share some here. The main content of this paper is the wiring mode of current transformer connected to ammeter and voltmeter.

首先，實物接線圖如下：

Firstly, the physical wiring diagram is as follows:

互感器，電流表，電壓表的實物接線圖

Physical wiring diagram of transformer, ammeter and voltmeter

相關產品說明：電流互感器3臺，電流表三只，指示燈三只，電壓表一只，LW2萬能轉換開關一個。

Related product description: three current transformers, three ammeters, three indicator lights, one voltmeter and one lw2 universal transfer switch.

基本的接線方式如上，附一些相關說明：

The basic wiring mode is as above, with some relevant instructions attached:

2 5 7接電源，3、6接電壓表

2, 5 and 7 are connected to the power supply, 3 and 6 are connected to the voltmeter

A，B，C相線，A接5，B接7，C接2。知識圖中所示接線，一般情況下，任意接，通過旋轉開關轉換供電壓表顯示相應兩相的電壓值即可。

A. B and C phase lines, a connected to 5, B connected to 7 and C connected to 2. Generally, the wiring shown in the knowledge diagram can be connected arbitrarily, and the voltage value of the corresponding two phases can be displayed on the power supply voltmeter by rotating the switch.
