In view of the major equipment quality problems found in the past two years
the structure and principle of the internal transformer of the primary-secondary fused pole-mounted switch are analyzed.This paper analyzes the root cause of unqualified temperature rise test through test and disassembly inspection
and finally puts forward improvement suggestions from test standard
