Chambers national teams of unilateral service CSR-393AV TYPE AND STATUS OF ITS INDEX vacuum switches

摘要

The invention relates to electrical engineering and can be used in the production of high-voltage equipment. Luggage team unilateral service type CSR-393AV comprises at the top of its housing busbars attached to the rear side of the housing a linear and tire adapted to be mounted in the gap it open contacts technological protective baffles, disconnectors, a high voltage vacuum switch mounted within the housing horizontal and closed at the front side of the removable panel with a window, a current transformer, outputted on the front side of the housing and disposed below the seat attachment high ovoltnogo vacuum switch levers drives the linear and bus disconnectors disposed on the front side of the housing, a low-voltage compartment, fixed with screws on the edge of shaft drive plate high-voltage vacuum circuit breaker, partly envelope the drive shaft axis, and having flat portions marked state high voltage vacuum switch, and the window removable panel formed at the respective side end of the chamber opposite the plate portion corresponding to the state of high voltage vacuum switch. Pointer state high voltage vacuum circuit breaker comprises a sleeve fixed to the high-voltage vacuum circuit breaker end of the drive shaft, a curved plate fixed to the sleeve and configured having two bulleted flat portion corresponding to ON and OFF states of high voltage vacuum switch, and partially envelope the sleeve in a plane perpendicular to the axis of the shaft drive.
