小型便携式电缆沟巡检小车的设计与应用

Design and Application of a Type of Portable Cable Trench Inspection Vehicle

随着国家电网公司少人及无人变电站的大力推行,变电站运维人员的维护工作量成倍增加。电缆沟常常发生积水、电缆脱落、防火封堵损坏等一系列缺陷,因此,规程要求检查电缆沟需要翻开电缆沟盖板进行定期检查,而人力检查电缆沟需要翻动每1块电缆沟盖板,且由于电缆沟盖板沉重、不宜翻动,导致工作费时、费力,人员容易受伤,设计了1种可反复修改动作指令程序的、检查变电站电缆沟情况的便携式遥控小车,用于替代人工检查电缆沟。

With the vigorous implementation of State Grid company’s less-staff and unmanned substations, the maintenance workload of substation personnel has increased exponentially. Because the cable trench often suffers water accumulation, cable fall-off, fireproof plugging damage,etc., the regulations require that the cable trench cover should be opened for regular inspection. However, if this job is done by manpower, it is laborious and easy to get injured. This paper describes a portable remote control vehicle that can repeatedly modify the action command program to check the condition of the substation cable trench, which is used to replace the manpower to inspect the cable trench.
