This master's thesis is focused on comparison of various conception of slide contacts. Studies of this theme are based on laboratory models and consequential experiments and measurements to the application of innovated slide contacts. The innovation is based on application Teflon on the slide contact's components. In this project there are presented results from measurements with application of innovated brushes „sT“, brush holders with „sT“ and new conception of slide contact with auxiliary teflon brush on DC machine. Next part is about innovation of trolley-bus traction collector, which was used on trolley-bus and results of its laboratory experiments. The last part presents results of long term experiments with "sT" technology, which was applicated in a few variants of industrial usage. |
