Fault Handling of Catenary Overhead Line System Ratchet Compensation Device
With the increasing requirements for safety and stability of the railway traction power supply system,the catenary,as the main component of the railway power supply system,should play an important role in ensuring the normal operation of the electric locomotive.The ratchet compensation device is an important part of the catenary,often used in the catenary suspension system of railway,subway and light rail,is a tension adjustment device,with the characteristics of high compensation efficiency and good braking performance of broken line,mainly used to continuously adjust the tension of the clue and reduce the scope of the accident,so as to ensure that the catenary con-tinues to supply the electric locomotive with electric energy to meet the normal operation of the train.Ratchet compensation devices are widely used because of their advantages of flexible rotation,high transmission efficiency,fast disconnection braking,and ability to reduce the scope of accidents[12].
