there is nothing to expand ...

\define at key[psset]{pst-3d}{normal}{\def\psk at normal{#1 }}


the space behind #1 is important.
my working example:

\documentclass{article}

\usepackage{pst-3d}
\makeatletter
\define at key[psset]{pst-3d}{normal}{\def\psk at normal{#1 }}
\makeatother
\begin{document}

   \ThreeDput[normal=30 cos 0 30 sin ](0,0,0){(some graphics)}

   \ThreeDput[normal=-30 cos 0 -30 sin ](2,0,0){(some graphics)}

\end{document}
