FIELD: mechanical design of electric switching apparatuses and method for their assembling.
SUBSTANCE: proposed electric switching apparatus has arc-control casing designed to accommodate at least one pole arc-control unit that incorporates two laminated arc-control units disposed either side of movable contact bridge along horizontal axis. Arc-control casing has first member incorporating base formed by first horizontal side of switching apparatus to organize chamber that has space for first laminated arc-control unit and second member connected to first one; second member has base formed by second horizontal side of switching apparatus opposing first one to form chamber that has space for accommodating second laminated arc-control unit.
EFFECT: enhanced mechanical strength and tightness of switching apparatus at superhigh gas pressures, facilitated assembly and reduced time required for this procedure.
