Пристрій для підтримання оптимального натиску струмоприймача трамвая

Abstract

A device for maintaining optimum pressure of a current collector on an overhead contact system includes a pressure sensor, a setting device of reduced masses of the current collector and a catenary, a speed sensor, a differentiator, functional converters, setters of the value of contact pressure, AD converter, comparators, a sensor of height of contact wire, an indicator. In case of change of motion parameters, in particular of speed, carriage loading, relief, the device generates and supplies a control signal to the circuit of electric drive of a spring of current collector and an adjusting signal to the circuit of traction electric drive of the tram.
