怎樣閱讀電氣原理圖

How to read the electrical schematic

怎樣閱讀電氣原理圖電氣原理圖一般分為主電路和控制電路及保護電路。主電路中通過的電流相對較大，主要是對壓縮機、風機、水泵、電加熱等主要用電設備供電；控制電路主要是給控制器及控制器外圍的電器元件如交流接觸器、過流保護器等供 ...JEM電線JEM電纜JEM電機引接線

How to read electrical schematic electrical schematic generally divided into main circuit and control circuit and protection circuit. The current in the main circuit is relatively large, mainly for compressor, fan, water pump, electric heating and other main electrical equipment. The control circuit is mainly for the electrical components such as AC contactor and overcurrent protector on the controller and controller.

雙控開關的接線方法圖解JEM電線JEM電纜JEM電機引接線

Diagram of connection method of double control switch

雙控開關的接線方法圖解雙控開關就是一個開關同時帶常開、常閉兩個觸點 L L1 L2（即為一對）。通常用兩個雙控開關控制一個燈或其它電器，意思就是可以有兩個開關來控制燈具或電器的開關，比如，在樓下時打開開關，到樓上后關閉開關。 如果 ...

The double control switch wiring method graphic double control switch is a switch at the same time, often open, often closed two contacts L L1 L2 (that is, a pair). Usually two double control switches are used to control a lamp or other electrical appliances. It means that there are two switches to control lamps or electrical switches. For example, turn on the switch downstairs and turn on the switch after upstairs. If...

家裝電線的顏色代表什么？怎么識別零火線？

What does the color of the household wire represent? How to identify the zero fire line?

家裝電線的顏色代表什么？怎么識別零火線？火線：紅色零線：黃色、綠色、藍色地線：黃綠雙色 其實單純的靠電線顏色分辨零火線的都是新手，吃過虧的電工都不會單純的根據經驗去判斷，而是通過試電筆測試后來判斷零火線，所以一只好的測電筆是電工生命的保障。

What does the color of the household wire represent? How to identify the zero fire line? The red line: zero line: yellow, green, blue and yellow green color in the ground: simply by wire color resolution zero are novice, suffered losses are not simply according to the electrical experience to judge, but through shidianbi test later to determine zero FireWire, so a good electrical life test pencil the security.
