摘　　要：开关柜是电网设备的重要组成部分,内部湿度是影响开关柜正常运行的关键因素之一,与开关柜相连的电缆沟是开关柜湿气的主要来源。文章分析了传统混凝土预制电缆沟盖板的弊端及现有电缆沟除湿现状,通过对盖板挠度和位置等相关因素的对比试验,提出了一种应用于室内,由焊冲孔网和不锈钢格板组合而成的盖板,使电缆沟的通风除湿效果达到最优,并介绍了实际应用情况。As an important part of power grid equipment,the internal humidity is one of the key factors affecting the normal operation of the switch cabinet,and the cable trench connected with the switch cabinet is the main source of the moisture in the switch cabinet.This paper analyzes the disadvantages of the traditional concrete precast cable trench cover plate and the present situation of cable trench dehumidification.Through the comparison of related factors like cover deflection and position,the paper presents a kind of cover plate,made up of welded punching mesh and stainless steel lattice plate and applied indoors to optimize the ventilation and dehumidification effect of cable trench,and then introduces the practical application.
