道岔懶人包(二) 高鐵道岔(2)-轉轍器 For Dummies 2: HSR Switches
高鐵轉轍器內部結構。

高鐵轉轍器之主要構件包括:馬達、電源切斷開關、微動開關、離合器、滑動偵測桿、推動桿及轉轍器箱體與蓋。
轉轍器的故障以機械與電氣2類為主,目前除微動開關異常正積極進行改善與控制外,其餘問題已甚少發生。因轉轍器是由機械、電機與電子零件組成,有其生命週期限制,可能因單一或多種因素發生故障,就像人會生病、汽車會故障一樣;但是人生病、設備故障,都有其徵兆及過程,然後才會發病、故障,故轉轍器如能透過勤加檢查、持續監控,當有故障徵兆時即預作處理及排除,即可降低後續造成的影響。
轉轍器故障的具體改善作為包括:加強對微動開關未正式使用前的檢驗、增加檢查及保養頻率、執行24小時監測、增加維修駐點及維修人力等,只要一發現有故障的徵兆時立即檢查及排除,可避免影響高鐵列車正常運轉;即使轉轍器發生故障,因為高鐵系統有自動安全保護設計,並無安全上的疑慮。
俗話說「預防勝於治療」,轉轍器也是一樣,經由持續的監測與定期保養,一發現有故障徵兆就及時加以排除或隔離,可有效降低營運中斷的風險。

The major components of a HSR switch are motor, power switch, snap switch, clutch, sliding detection lever, pushing rod, and box & lid of the switch.
Switch malfunction includes mechanical and electrical failures. Currently, the most frequent problem occurs at the snap switch in which the HSR team is actively preventing and controlling the situations. Malfunction in other parts of the switch happen rarely. Due to the composition of the switch including mechanical, electrical and electronic parts, each part is limited by its life cycles. Like all life forms and machinery, the switch parts can be detected of errors prior to the actual failure. Thus, frequent examination and constant monitoring will effectively eliminate malfunctioning errors promptly before they lead to consequential impact.
Improvement measures to prevent malfunctions include enhance pre-usage examinations on snap switches, increase inspection and periodical maintenance frequencies, fully execute 24-hour non-stop monitoring and increase maintenance stations (call points) and manpower. All errors shall be eliminated promptly after confirmed detection to avoid further impact to normal HSR operation. Moreover, since the HSR system is designed with fail-safe concept, the HSR system shall still be risk-free even if the switch malfunctions.
As the saying goes "prevention is always better than cure", by constantly monitoring and periodically maintaining the switch and eliminate or isolate the errors immediately, the risk of switch malfunctions affecting HSR operation will be greatly decreased.
