将 CircuiTikz 接地符号重新定义为 IEC 60417 变体

是否可以将 CircuiTikz 接地符号更改为更像 IEC 60417 接地符号？

答案1

是的！

我稍微改变了坐标和线宽，使其看起来更相似：

您要求的符号全部都是单极子，它们在文件中定义pgfcircmonopoles.tex。

以下是重新定义的单极子的代码：

您可以将其另存为 newmonopoles.tex，然后就可以了\input{newmonopoles}。或者，您也可以直接将此代码粘贴到您的 .tex 文件中。

以下是我上面展示的示例文档：

\documentclass{article}

\usepackage{tabularx}
\newcolumntype{C}{>{\centering\arraybackslash}X}

\usepackage{circuitikz}

\begin{document}
\pagenumbering{gobble}

CircuiTi\emph{k}Z versions:\hfill
\begin{tabularx}{0.6\textwidth}{*{4}{C}}

\tikz\draw (0,0) node [nground] {};&
\tikz\draw (0,0) node [pground] {};&
\tikz\draw (0,0) node [cground] {};
\end{tabularx}

\input{newmonopoles}
