Abstract
SC350 switches are difficult to maintain and have a high failure rate due to factors such as complex structure,densely located connection parts,and difficult adjustment.This paper analyzes and discusses the typical problems encountered during the maintenance of this type of switches,such as the high rebound force of the switch rail,switch gap,asynchronous switch point closure,and improper closure of the point frog.Based on on-site maintenance practices,measures are proposed mainly from the perspective of electrical maintenance,including distinguishing the source of the rebound force of the switch rail,relieving the stress on the frames,standardizing the adjustment of the throw of switch,and inspecting the relative state of the point frog,in order to reduce the failures of this type of switches.Through practical application of the aforementioned methods and measures,the failure rate of the SC350 switches has been significantly reduced.These analyses and maintenance suggestions are of great significance for enhancing the reliability and safety of the application of the SC350 switches.关键词
