METAL-CLAD TYPE SWITCHGEAR

摘要

The present invention relates to a metal closed type switchgear, capable of maintaining a control circuit when a high voltage circuit is in a live wire state by stacking two feeders in a housing having an existing size and separately making a control means in each circuit breaker to be embedded in a separate compartment. In addition, the metal closed type switchgear separately provides a pressure relief passage to upper and lower circuit breaker rooms, a bus bar room, and upper and lower cable rooms not to transmit aftereffects of an accident to a neighboring distributing board and reduces maintenance costs and manufacturing costs.
