Safety cutting contact with the electric motor, and potential separation of control unit and the cutting tool by means of optical waveguides - art (cutting facility with potential separation)

摘要

Safety - cutting facility, and electric potential isolation of operating unit and the cutting tool (cutting facility with control-to-load isolation) characterized in that the cutting in the case of a safety system of conventional design (si - plant) as the insulating distance between the cutting tool and the drive element which determines, as well as the safety distance, the electrically insulating, flexible hydraulic hose line as well as the in hydraulic hose line and the hydraulic system which is located as a pressure medium, insulating hydraulic fluid are replaced by one for the hydraulic operation of the invention, it is a general purpose, and not by their electrical (insulating) characteristic values and their length certain hydraulic hose line as well as a for general hydraulic applications usual hydraulic oil or also that the drive for the cutting tool; in the case of the omission of the hydraulic system hose line, is coupled directly to the cutting tool and with the latter forms a functional unit.
