Problems solved by technology

[0002] The prefabricated cabin type substation is composed of a prefabricated cabin, a secondary equipment screen cabinet (or rack), a high-voltage cabinet, and cabin auxiliary facilities. The on-site primary equipment and secondary equipment are placed in the prefabricated cabin and battery prefabricated cabin. The main and secondary equipment prefabricated cabins are in two other warehouses; the primary equipment, secondary combined equipment, and batteries in the prefabricated cabins are all manufactured, assembled, wired, and debugged in the factory, and transported as a whole in the form of a box room to the project site; due to the large size of the prefabricated cabin, the prefabricated cabin needs to be hoisted to the prefabricated position by a truck crane for installation, and then the prefabricated cabin will be lowered to the prefabricated position through the command and cooperation of the on-site staff; Unified debugging is required, the overall construction workload is large, the construction period is long, and the construction details are cumbersome, and a little carelessness will bring indelible losses to the construction; so now a complete set of construction methods is urgently needed

Embodiment Construction

[0072] Below in conjunction with accompanying drawing, the present invention will be further explained and illustrated:

[0073] see figure 1 , a substation prefabricated cabin installation construction method is characterized in that: comprising the following steps:

[0074] 2) Construction preparation

[0075] A. Prepare the tools for hoisting and check whether the prefabricated cabin is damaged;

[0076] B. Clear the obstacles on the site, and take safety measures such as anti-tilting and anti-collapse of the crane before hoisting

[0077] C. After the prefabricated cabin is in place, bend the grounding lead model, and cut the material according to the size of the model. When cutting the material, a margin should be left. During the bending process of the flat steel, mechanical cold bending should be used to avoid hot bending damage to the cast layer; after production The grounding lead wire of the prefabricated cabin is bolted and fastened to the special grounding piece...
