电动葫芦远程控制故障的解决

分析了视频远距离遥控操作防爆电动单梁起重机控制装置频繁出现故障的原因,即控制箱受到多方面的震动影响,控制线路上产生较大的线路压降.将控制箱移至地面靠近电源处,减小了线路电压降,避免了震动影响.实际运行降低了故障率,也保证了检修人员的安全.

A Solution to the Electromotion Calabash Remote Distance Control

Failure causes on video control explosion-proof electric single-girder crane controlling device are analyzed, i.e., the controlling box is affected by the vibration from every side of the controlling box and a greater pressure drop is caused on the controlling circuitry. Remove the control box to the ground near the power supply, which can reduce the circuitry voltage drop and avoid the effect of vibration. This innovation can not only reduce the failure rate in the actual operation, but also assure the safety of the maintenance personnel.
