浅析“同名端”的应用

The Application of the Dotted Terminal

在分析电路原理、观察仪表或使用某些电气设备时,经常遇到“*”或“·”的特殊标记,此即“同名端”。在某些电器的实际使用中,如果不注意同名端的标记,会造成电器无法正常使用,甚至烧毁电器等严重后果。笔者就“同名端”在变压器、功率表中的应用作了较详细分析。

In the course of analyzing the principles of the electric circuits, the meters or using some electric equipment, we often come across some special marks such as ' * 'or '· ', namely, the 'Dotted Terminal'. Negligence of these marks may cause the failure, even burnout of the electric devices. The author offers a detailed analysis of the application of the 'Dotted Terminal' in voltage transformer and power meter.
