HIGH VOLTAGE SWITCHGEAR HAVING ROUNDING SHIELD FOR ENHANCING THE DIELECTRIC STABILITY AND SHIELD EDGE STRUCTURE OF HIGH VOLTAGE SWITCHGEAR

摘要

PURPOSE: A high voltage switchgear with a curved shield and a barrier rib structure for improving insulating stability are provided to improve electric stability of a high voltage switchgear by preventing accidents due to dielectric breakdown between a vacuum circuit breaker pole and a metal barrier rib in the high voltage switchgear. CONSTITUTION: A metal barrier rib(20) is formed with a barrier rib structure. A number of inserting holes are formed on one side of the metal barrier rib. A surface mounting member(30) is combined with an outer circumferential area of the inserting hole. A vacuum circuit breaker(10) is mounted on inside of the metal barrier rib. A shield edge(50) is combined with a connection part(40) of the metal barrier rib and the surface mounting member.
