电表怎么接线(家用220v电表接线图)
大家好，我是小豆。今天介绍一种非常常用的电器元件，基本上家家户户都在用。电能表是家庭使用的单相电表。首先，我们来看看家用电路。
1.电源电涌保护器通常与电路系统并联。雷击时，进入建筑物内的各种金属管道、电线产生高强度电磁感应，产生大量脉冲能量。电源浪涌保护器将起到引导过电流到大地和降低设备各端口电位差的作用。
2:外引电表，表盘，10000 1000 100 1 0.1。读数时，小数点不读，其他正常读数。220伏5-20安50赫兹
3.接线方式:单相表接线公式；一二三进二四出。下图中，火线进1号好端子，2号端子出火线，3号端子进零线，4号端子出零线。公式是火线1，零线3，火线2，零线4。
