登車橋控制系統(tǒng)短路的原因分析
1
、登車橋http://www.8kvv.com/局部電路短路，觸點(diǎn)粘合
，登車橋開關(guān)不釋放等，這種短路不產(chǎn)生大電流
，熔斷器保持完好
。一般表現(xiàn)為電梯失控或電路上出現(xiàn)某一繼電器不能釋放。
Ramps partial short circuit, contact adhesive, Ramps switch is not released, etc., this does not produce a large short-circuit current, the fuse intact. The general performance of the elevator control or a relay can not be released on the circuit appear.

，短路后產(chǎn)生極大的短路電流，能將熔斷器熔體燒毀；由于故障現(xiàn)象明顯，對(duì)登車橋電路分析即能查得排除，也可根據(jù)這一繼電器的有關(guān)登車橋電路進(jìn)行分段斷開，逐步將故障排除。
Ramps power short-circuit, short circuit generates a great short-circuit current, can melt the fuse burned; the obvious symptom of Ramps circuit analysis that is able to exclude Richard also be in accordance with the boarding of the relay bridge circuit is disconnected segments, gradually troubleshooting.
