电气接线图讲解

Explanation of electrical wiring diagram

电气接线图讲解接线图是根据电路原理图绘制的，应按照原理图来看。下图为接线图实例。 先看主电路，再看控制电路。看接线图要根据端子标志、回路标号，从电源端顺序查下去，搞清楚电路的走向和电路的连接方法，及搞清楚每个元器件 ...

Electrical wiring diagram explanation wiring diagram is based on the circuit schematic drawing, should be in accordance with the principle of view. The following diagram is an example of the wiring diagram. First look at the main circuit, and then look at the control circuit. The wiring diagram should be checked down from the terminal of the power supply according to the terminal mark and loop label, and we should make clear the way of the circuit and the connection method of the circuit, and figure out every component.

如何区分和判断火线零线地线

How to distinguish and judge the zero line ground wire of fire line

如何区分和判断火线零线地线在家里一般我们可以用颜色来区分，正常情况下黄色绿色红色三种颜色是火线，蓝色是地线，黄绿双色是地线。无法区分颜色时得用电笔来区分；当验电笔亮就是火线，不亮就是零线或地线。 亮是火线 不亮是零线对于零线和地 ...JGG电机引接线如何区分和判断火线零线地线

How to distinguish and judge the zero line ground wire at home can be distinguished by color. Under normal circumstances, yellow, green and red are the three kinds of fire lines, the blue is the ground wire, and the yellow green double color is the ground wire. Cannot distinguish between colors when using pencil to distinguish; when the test pencil light is not bright is FireWire, zero line or wire. The light is that the fire line is not bright, the zero line is to the zero line and the ground.
