Abstract

During the winter und summer half I pass 50days university practice and in this time I from beginning familiarized with processes of firm Elektropohony s.r.o. At first I operated in electric workshop where I acquainted with single components of switchboards, assembly and connection from drawing documentation. My final task of this practice was: design switchboard for ski-lift and sequentially connect it up and prove. My project solves speed regulation of ski-lift drive, whereas motor is fed from frequency convertor V1000-VZA4011 FAA. This solution gives the higher comfort of ski-lift operation, because enables continuous run-up, after-running und continuous adjustable speed. Frequency convertor saves asynchronous motor against overload and together with other instrumentation is situated in switchboard 1RM11. Connection diagram is mentioned in drawing documentation.
