江苏春晨电缆有限公司生产JEH电机引接线电机引出线电机绕组线,高压电机引接线，星形接法和三角形接法？三相电负载连接方法的选择
Star connection and triangle connection? Selection of three phase electric load connection method
如果本文中有些难理解的疑点，您可能需要了解负载的星形连接、负载的三角形连接的各自特点。
If there are some difficult questions in this article, you may need to understand the characteristics of the star connection of the load, the triangle connection of the load.
在对称三相电路中，对于负载的连接方法来讲，究竟是采用星形接法还是三角形接法？
In a symmetrical three-phase circuit, is it a star connection or a triangular connection for the load connection method?
我们要根据各相负载额定电压与电源线电流的大小而定，其主要依据两个：JEH电机引接线电机引出线电机绕组线
We must depend on the rated voltage of each phase and the current of the power line, which is mainly based on two:
如果各相负载的额定电压等于电源线电压的1/√3（1÷√3，也就是说线电压等于额定电压的根号3倍）时，则负载的连接应采用星形接法。
If the rated load voltage of each phase is equal to the power line voltage of 1/ V 3 (1 / 3 V, that is to say the line voltage is equal to the rated voltage of the square root of 3 times), the load shall be connected with star connection.
例如三相电炉铭牌上的电压是220V，电源线电压为380V时，额定电压是三相电源线电压的1/√3（根号3=1.73）时，因此采用星形连接。
For example, voltage three-phase furnace on the nameplate is 220V, power line voltage is 380V, rated voltage of three-phase power line voltage of 1/ V 3 (root 3=1.73), so the use of star connection.
如果各相负载的额定电压等于电源的线电压时，则负载应采用三角形接法。如有一台电动机（三相电动机）其铭牌上的额定电压为380V，与电源的线电压相等，因此应采用三角形联连接。JEH电机引接线电机引出线电机绕组线
If the rated voltage of each phase is equal to the line voltage of the power supply, the load should be triangular connected. If a motor (three phase motor) has a rated voltage of 380V on its nameplate, it is equal to the line voltage of the power supply, so a triangle connection should be used.
对于三相负载来讲，选用什么方式的接法是非常重要的，**不可接错。如果错误的选用了连接方法，将有可能会出现以下故障
For three phase load, it is very important to **ose the way of connection. If the connection method is wrongly **sen, the following failure may occur
本应采用星形接法而错误的采用三角形连接，结果是每相负载的相电压比额定电压升高√3倍，这样导致线电流和电功率要增大3倍，负载将会倍烧坏。
This should be the star connection and error by triangular connection, is the result of every phase voltage load than the rated voltage increases 3 times which leads to tick, line current and electric power will increase 3 times, the load will burn out times.
应采用三角形接法而错误选用星形连接时，每相负载的相电压只有额定电压的1/√3，电流、电动势也随之减少，负载会因功率不足而引发事故。
The triangle connection method and error selection of star connection, each load phase voltage of the rated voltage of 3 V only 1/, current, electromotive force is also reduced, the load due to power shortage caused by accident.
