Requirements for increasing operational reliability of pantographs continually grow in relation to increased speeds and operational conditions. Prevention of current collector failures can be attained by using automatic devices for diagnostical tests directly on tracks and at stations. One of the chief characteristics of the current collector is its static depression. The analysis of existing methods and mechanisms for verification of the static depression characteristics permitted composition of a generalized structural schema for automatic registration of the current collector depression (ARNT) and formulation of the basic technical requirements for its production. This article presents a description of devices for registration of the current collector depression; characteristics are examined and its operational peculiarities are analyzed. The fundamental goal of utilizing the proposed mechanism is increased reliability of the current collector due to control and registration of its static characteristics in its entire operational range. The mechanism must avoid damage to the catenary network and current collectors, lower the wear and tear of the catenary leads, and the collector's plates. Completion of economic calculations revealed the expediency of working out this device. The mechanism allows automatic measuring of the static depression in the entire operational of range heights without a stop of the electric locomotive. The operation revealed its capability and the simplicity of servicing, and finally, with the complete operation of the ARNT-4 mechanism ensures reliable operation with established accuracy.
