Abstract

This paper analyzes the 10 kV system removal-type switchgear’s accident reasons of two times 3-phase short circuit to ground occurred in normal operation

and the accident caused the personnel injury;puts forward the improvement measures of removal-type switchgear potential insulation defects.To avoid the similar accident happen again

the measures have been performed.The selection requirements of removal-type switchgear have been improved and the standard guidelines have been provided for Guangdong Power Grid Corporation use health and safety equipments.
