Title:
SWITCHGEAR SYSTEM HAVING TRUCK DRIVEN SHUTTER MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/178964
Kind Code:
A1
Abstract:
A switchgear system and a method for operating the switchgear system are disclosed. The switchgear system (100) may include a switchgear frame (124) and a truck (150) carrying a circuit breaker (250) and supported for linear movement on the switchgear frame. A drive mechanism (152) may rack in the truck where the circuit breaker is in electrical connection with primary circuit contacts (220a), and may rack out the truck where the circuit breaker is electrically disconnected from the primary circuit contacts. As the drive mechanism racks in the circuit breaker, a shutter linkage (316) moves a shutter (312, 314) opened, and as the drive mechanism racks out the circuit breaker, the shutter linkage moves the shutter closed over the primary circuit contacts. The switchgear system includes shutters that cover primary circuit contacts, but not cause sparks and burning.
