  • 加热管的接线方法及三角形接法与星形接法的区别

    2015年11月20日 by admin

    加热管的接线方法:

    如果是额定电压220V的加热管,要接在380V的电路中,需要采用星形接法。
    如果是额定电压380V的加热管,要接在380V的电路中,需要采用三角形接法。
    如果是额定电压380V的加热管,采用星形接法,则达不到加热管的额定功率。实际功率为原来额定功率的(220*220)/(380*380) .约三分之一左右。

       电热管的发热主要是靠内部的电热丝通过电流发热,而接线方式决定了通电的电流电压状态,所以说电加热管的接线方式很重要。关于接线方式对电热管的影响可以通过关于电热管接线方式的影响一文了解。电热管在合理的使用条件下,电压和功率越大发热效率越高。而加热管接线方式则决定了外部电压电流通过电阻丝的方式,所以说电热管的接线方式的选择具有很重要的现实意义。那么我们如何选择电加热管的接线方式呢?
    下面就这个问题做简要介绍:电热管的接线方式在加热管上常用的有两种:三角形接法和星形接法(也就是俗称的Y形接法)
    1、三角形接法:
    ①三角形接法:电加热管每个元件的首端接另一个元件的尾端,三个接点分别接三根相线的接线方式;
    ②三角形接法的特点:三个电加热管元件额定电压为380伏;如三个元件电阻值不同,也不影响这种接法的可行性。三角形接法比星形接法功率和电流都三倍。
    2、星形接法:
    ①星形接法:三个电热管的加热元件,每个元件的首端连在一起(这个点称中性点),三个尾端分别接三根相线的接线方式。
    ②三个元件额定电压为220伏时;如果三个元件电阻值不同,则中性点应该接零线。

    翻译:Electric heating pipe connection methods:

     

    If the heating tube is rated voltage 220 v, to pick in the 380 v circuit, need to use y connection.

    If the heating tube is rated voltage 380 v, to pick in the 380 v circuit, need to adopt the delta connection.

    If the heating tube is rated voltage 380 v, adopts y connection, could not reach the rated power of heating tube. The actual power as the original power rating (220 * 220)/(380 * 380). About a third.

     

    Electric heat pipe heat is mainly rely on internal heating wire through the current fever, and connection mode determines the current of the electric voltage state, so it is important to the connection mode of electric heating tube. Effect on connection mode of electric heat pipe can be through the effects of electric heat pipe connection mode is understanding. Under the condition of reasonable use, electric heating tube voltage and power, the greater the heat efficiency is higher. While heating pipe connection mode determines the external voltage current through the way of resistance wire, so the choice of the connection mode of electric heating tube has very important practical significance. So how do we choose the connection mode of electric heating tube?

    Here is to do a brief introduction to the problem: the connection mode of electric heating tube used in heating tube has two kinds: delta connection and Y connection (also known as Y connection)

    1, the delta connection:

    1) delta connection: electric heating tube head end of each element after the end of another component, the three contacts respectively by three phase line connection mode;

    (2) the characteristics of the delta connection: three electric heating tube elements rated voltage of 380 v; Such as three components resistance value is different, also does not affect the feasibility of this kind of connection. Delta connection is three times than y connection power and current.

    2, y connection:

    (1) y connection: three electric heat pipe heating elements, each element of the head end together (this point called a neutral), three end respectively by three phase line connection mode.

    (2) three elements when the rated voltage of 220 v; If the three components resistance value is different, the neutral point should be zero.
