Switching device and a switchgear

A switching device for electric power distribution, electrically connectable to an electrical conductor, the switching device comprising:

• a breaker electrically connectable to the electrical conductor, and
• an at least partially electrically conductive housing to which the breaker is mounted, the housing having an outer surface,
• the breaker comprising at least one electrically conductive first contact and one electrically conductive second contact, the second contact being movable and in relation to the first contact and in relation to the housing, and when the first and second contacts are in contact the breaker is in a closed position, and when the first and second contacts are separated the breaker is in an open position,
• the switching device being arranged to provide a current path between the breaker and the electrical conductor, and
• the housing houses at least one guiding member for operating the second contact, the at least one guiding member being movable in relation to the housing,
• the at least one guiding member comprising a biasing assembly arranged to bias the second contact against the first contact when the breaker is in the closed position, and
• the biasing assembly comprising a plurality of biasing members comprising a first biasing member and a second biasing member, characterized in that
• the housing is provided with a through-hole for suspension of the housing,
• the switching device comprises a shaft inserted into the through-hole of the housing, the shaft is rotatable about its longitudinal axis and in relation to the housing, the shaft is connected to the at least one guiding member and in that the shaft and its rotation is adapted to control the movement of the at least one guiding member,
• characterized in that the second contact is axially movable along a first axis, and in that the first biasing member is radially displaced from the second biasing member in relation to the first axis,
• characterized in that the biasing assembly is movable in the direction of the first axis, and in that the biasing assembly is indirectly or directly connected to the second contact,
• characterized in that the at least one guiding member comprises at least one pivoting arm rotatable about a pivot axis, in that the pivoting arm and the biasing assembly comprise complementary guiding means for transferring rotary movement of the pivoting arm to axial movement of the biasing assembly, and in that the pivoting arm is arranged to control the axial movement of the biasing assembly and of the second contact.
