摘要
Abstract
To support the on-site switch transformation from single-machine driving to double-machine driving with ZD9 DC switch machines,research work is conducted for ZD9 DC switch machines suitable for four-wire double-machine driving control circuit.The transmission ratio of the transmission system composed of gear box and lead screw is adjusted to allow the ZD9 switch machine to meet the technical requirements for switching time and working current.The ZD9 switch machine suitable for four-wire double-machine driving control circuit is tested in view of the usage characteristics of the four-wire double-machine driving control circuit.The test results indicate that the proposed switch machine can meet the requirements for on-site application.Moreover,maintenance recommendations are made for on-site application.关键词
