Double flexible catenary latch
The paper analyzes operating conditions of a typical articulated catenary latch and identifies its main drawbacks. New designs of the device locking the contact wire are proposed, their parameters are given, advantages and disadvantages discussed. The methodology of experimental research of the proposed devices is described, and its results are discussed. Performance of the proposed devices is compared with standard latch. Conclusions are made about the appropriateness of the proposed designs, and ways to improve them are formulated.
