大型落地式动力配电箱的安装一般是分散靠墙安装在厂房内。调查表明,有的配电箱贴墙(柱)安装,距墙柱距离仅2～3cm而产生压迫感,有的则距墙柱过远而形成孤立感。动力配电箱最佳距墙柱距离应是10±1cm,而且箱背与墙柱之间的间距形成穿堂风,利于箱体散热.并便于穿线和维修。现以XL-21型动力配电箱为例(图
Large floor-mounted power distribution box installation is generally scattered around the wall installed in the plant. Survey shows that some distribution boxes attached to the wall (column) installation, distance from the wall column only 2 ~ 3cm and create pressure, while others are far away from the column and the formation of a sense of isolation. Power distribution box The best distance from the wall column should be 10 ± 1cm, and the back of the box with the formation of the spacing between the wall columns to create a hallway wind, which will help the cabinet heat. And easy to threading and maintenance. Now to XL-21-type power distribution box as an example (Figure
