Subway substation direct current equipment insulation construction method based on BIM prefabrication
The invention discloses a BIM (Building Information Modeling) prefabrication-based insulation construction method for subway substation direct-current equipment, which comprises the following steps of: according to a design drawing and an equipment manufacturing drawing, adopting BIM modeling, determining the sizes of a basic channel steel frame, an insulation cushion block and an insulation plate and the positions of hole sites in the basic channel steel frame, the insulation cushion block and the insulation plate, and performing factory prefabrication processing; the insulating cushion blocks and the insulating plates are additionally arranged between the DC equipment cabinet base and the basic channel steel frame, so that the upper and lower fixing bolts are not communicated with each other, the basic channel steel frame and the DC equipment cabinet base are completely isolated, and splicing seams of the adjacent insulating cushion blocks are blocked by the sealing plates, so that the pollution of dust and impurities on the ground is completely eradicated; therefore, electrical isolation between the cabinet metal frame and the basic channel steel frame of the direct current equipment is realized, condensation conduction between the bolt metal piece for fixing the cabinet body of the direct current equipment and the basic channel steel frame under a humid working condition is avoided, and the acceptance requirement of ground insulation of the direct current equipment is met.
本发明公开一种基于BIM预制的地铁变电直流设备绝缘施工工法，根据设计图纸以及设备制造图纸，采用BIM建模，确定基础槽钢框架、绝缘垫块和绝缘板的尺寸，以及基础槽钢框架、绝缘垫块和绝缘板上各孔位的位置，进行工厂化预制加工，在直流设备柜体底座与基础槽钢框架之间增加绝缘垫块与绝缘板，使上下固定螺栓之间彼此不连通，基础槽钢框架与直流设备柜体底座之间完全隔离，相邻绝缘垫块拼缝之间采用封板封堵，杜绝地面灰尘杂质污染，以此实现直流设备的机柜金属框架与基础槽钢框架之间的电气隔离，避免了在潮湿工况下，固定直流设备柜体的螺栓金属件与基础槽钢框架之间被凝露导通，达到直流设备对地绝缘的验收要求。
