LI Duan-jiao. Improvement of Potential Defects for 10 kV System Removal-type Switchgear[J]. High voltageapparatus, 2013, 49(2): 110-115+119. DOI: 10.13296/j.1001-1609.hva.2013.02.022.
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.
