HV switching unit for mining equipment - has grounded rod with insulated handle insertable into eyelet contacts to ground them

摘要

The switching unit supplies mining equipment with a high voltage and has a connection box (4) at one end. The connection box contains grounding connected to feedthrough conductors. The grounding contacts can be connected to a grounded conductor (14) in the connection space. The grounding contacts are eyelets. A grounding rod (12) can be inserted through the eyelets to ground them. The rod has an insulating handle (13) for this purpose and is connected to the flexible grounded conductor (14). The grounding rod is rotated to lock it in the grounded position.
