江蘇春晨電纜有限公司生產(chǎn)YFFB扁電纜三相交流電，單相交流電主要有單相兩線式、単相三線式供電方式。家庭用電一般都是單相交流電，單相與三相交流電照明配電線路圖解
Diagramming of single phase and three phase alternating current lighting distribution lines
單相交流電主要有單相兩線式、単相三線式供電方式。家庭用電一般都是單相交流電。
The main power supply single-phase AC single-phase two wire, single phase three wire. Household electricity is usually a single phase alternating current.
1）單相兩線式
1) single phase two line type
單相兩線式照明配電線路如下圖。
Single phase two line lighting distribution lines are illustrated as follows.
The two lines from the three-phase three line high voltage transmission line are sent to the high voltage transformer, and the voltage after voltage change (as from high voltage 6600V to 220V) provides 220V voltage to the home lighting line, the primary and secondary isolation of the transformer, and the voltage between the output fire line and the zero line is 220V.

2）單相三線式
2) single phase three line type
単相三線式配電線路圖如下。YFFB扁電纜三相交流電
Single phase three wire distribution circuit diagram as follows.
単相三線式供電中的一條線路作為地線與大地相連。此時(shí)，火線與地線之間的電壓為220V，零線N（中性線）與火線（L）之間電壓為220V。由于不同接地點(diǎn)存在一定的電位差，因而零線與地線之間可能有一定電壓。
Single phase three line power supply line as the ground wire is connected to the earth. At this time, the voltage between the fire line and the ground wire is 220V, and the voltage between the zero line N (neutral line) and the fire line (L) is 220V. Because there is a potential difference between different grounding points, there may be a voltage between the zero line and the ground wire.
