怎样阅读电气原理图

How to read the electrical schematic

怎样阅读电气原理图电气原理图一般分为主电路和控制电路及保护电路。主电路中通过的电流相对较大，主要是对压缩机、风机、水泵、电加热等主要用电设备供电；控制电路主要是给控制器及控制器外围的电器元件如交流接触器、过流保护器等供 ...JEM电线JEM电缆JEM电机引接线

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.

双控开关的接线方法图解JEM电线JEM电缆JEM电机引接线

Diagram of connection method of double control switch

双控开关的接线方法图解双控开关就是一个开关同时带常开、常闭两个触点 L L1 L2（即为一对）。通常用两个双控开关控制一个灯或其它电器，意思就是可以有两个开关来控制灯具或电器的开关，比如，在楼下时打开开关，到楼上后关闭开关。 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...

家装电线的颜色代表什么？怎么识别零火线？

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

家装电线的颜色代表什么？怎么识别零火线？火线：红色零线：黄色、绿色、蓝色地线：黄绿双色 其实单纯的靠电线颜色分辨零火线的都是新手，吃过亏的电工都不会单纯的根据经验去判断，而是通过试电笔测试后来判断零火线，所以一只好的测电笔是电工生命的保障。

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.
