摘　　要：ZDJ9道岔控制电路存在2DQJ继电器第一、二组加强接点拉弧灼烧氧化,导致的接点接触不良现象。因2DQJ第一组前接点与第二组后接点为表示共用接点,接点氧化可导致道岔失表故障;同时,道岔表示二极管存在被瞬间启动电流击穿的风险,也会导致道岔失表故障。现对道岔控制电路原理进行分析、调整电路逻辑,并对ZDJ9交流五线制道岔控制电路进行优化研究,避免道岔失表故障,来提高道岔设备的整体可靠性。The ZDJ9 AC fi ve-wire switch control circuits exhibit the phenomena of arcing,burning,and oxidation of the fi rst and second groups of strengthening contacts of the 2DQJ relays,resulting in poor contact of the contacts.Due to the fact that the fi rst group of front contacts and the second group of rear contacts of 2DQJ relays are shared contacts,oxidation of these contacts can lead to loss of indication of a switch;at the same time,there is a risk of instantaneous starting current striking and damaging outdoor diodes,which can also lead to loss of indication of a switch.The principle of the switch control circuits is analyzed,the circuit logic is adjusted,and the ZDJ9 AC fi ve-wire switch control circuits are optimized to avoid loss of switch indication failure and improve the overall reliability of the switch equipment.
