      为什么有些国际电联将蓝线用作地线

    


    

       安全与使用哪种色线无关。仅仅是电线设备的分色现在主要是一种标准化,以便识别实线的哪种颜色代表什么。对于外行来说,所有线路都是相同的,但是对于专业电工来说,看到线路并不是问题。 唯一的安全隐患是非专业人员按照常识进行操作。

      可以使用接地线代替零线吗?接地线用作中性线时会发生什么

    


    

       首先解释一下接地线和中性线:电力变压器的次级公共端,称为中性线,中性线端子将两根电线(一相和三根火线(相线))绞入房屋,这是众所周知的 作为同轴四线制,一根埋在地下并与变压器设备的外壳连接。到达房屋后,选择相线和中线之一。 两条线构成干线。 相线称为火线,中心线称为中心线。这显示了城市。

    

  



    

    

      

      24伏电流等于220伏电流测量

    


    

       24V电流与220V电流测量值相同吗? 首先,普及电能计量的基础知识。 毕竟,每个家庭都必须用电。 知道某些知识有助于保护他们的权利。电能表应直言不讳。 这是为了计算通过电表的电能消耗,通常称为多少度电。有三个数据,一个是电压,另一个是电流,第三个是时间。换句话说,要实现用电。

    

  



    

    

      

      开关L1和L2是否连接到火线和零线

    


    

       根据图片; 接线的位置和目的不同,我将针对不同的安装和目的回答以下接线方法:(1)如果用于带有三极插座的双控灯电源,则应使用以下接线方法: 开关插座面板左后侧双控制开关的L端子在一侧连接到电源相线(也称为主相线),然后在右侧。

    

  



    

    

      

      低压家庭配电的负载,电线和断路器的选择

    


    

       以下内容将根据家用低压220V电压分布,铜导体的近似负载功率以及匹配的断路器来回答您的问题,以保护导体的安全; 横截面为1平方毫米的铜导体的最大安全负载功率约为1000W,并且在线路开始处安装了跳闸电流波形6A的断路器或漏电断路器导体。 1。5级

      Why do some ITUs use the blue wire as a ground wire

    


    

       Safety is independent of which color thread is used.It is just that the color separation of the wire installation is now mainly a standardization in order to identify which color of the solid line represents what.For the layman, all lines are the same, but for professional electricians, seeing the line is not a problem. The only safety hazard is that non-professionals operate through common sense.

    

  



    

    

      

      Can the ground wire be used instead of the neutral wire?What happens when the ground wire is used as a neutral wire

    


    

       First explain the grounding wire and the neutral wire: the secondary common end of the power transformer, called the neutral wire, the neutral wire terminal twists two wires, one and three live wires (phase wires) into the home, which is well known的 作为三相四线制,一根埋在地下并与变压器设备的外壳连接。After arriving at the house, choose one of the phase and neutral lines. The two lines form a trunk line. The phase line is called the fire line, and the center line is called the center line.This shows the city.

      24 volt current equals 220 volt current measurement

    


    

       Is the 24V current the same as the 220V current measurement? First, popularize the basic knowledge of electric energy measurement. After all, every family must use electricity. Knowing certain knowledge helps protect their rights.The electric energy meter should be outspoken. This is to calculate the electric energy consumption through the electric meter, which is usually called how many degrees of electricity.There are three data, one is voltage, the other is current, and the third is time.In other words, to achieve electricity.

    

  



    

    

      

      Are switches L1 and L2 connected to live and neutral

    


    

       According to the picture; the location and purpose of the wiring are different, I will answer the following wiring methods for different installations and different purposes: (1) If it is used in the case of a dual-controlled lamp power supply with a three-pole socket; switch socket panel back leftThe L terminal of the dual-control switch on the side is connected to the power phase line (also called the main phase line), and then to the right side.

    

  



    

    

      

      The selection of load and wire and circuit breaker for low-voltage home distribution

    


    

       The following content will answer your question based on the household low voltage 220V voltage distribution, the approximate load power of the copper conductor and the matched circuit breaker to protect the safety of the conductor; the maximum safe load power of the copper conductor with a cross section of 1 square millimeter is about 1000W,并且在线路开始处安装了跳闸电流值为6A的断路器或漏电断路器 导体。 1.Level 5.
