What issues should be considered during the installation of a box-type substation?
Release time： 2025-02-11
I. Pre-Installation Preparations
-
Technical Preparation : Construction personnel must be familiar with the construction drawings and understand the model, specifications, technical parameters, and installation requirements of the box-type substation. Additionally, a technical briefing should be conducted for all workers to ensure everyone comprehends the construction process, quality standards, and safety precautions.
-
Equipment Inspection : Carefully inspect the packaged substation equipment to verify that its model and specifications meet the requirements, and check for any damage or deformation in its appearance.
-
Tool preparation : Prepare and debug all types of tools, ensuring that equipment like cranes is safe and reliable, and that small tools perform optimally.
II. Foundation Construction
-
Basic Requirements :The strength grade of the foundation concrete should not be lower than C20, the dimensional deviation of the foundation must not exceed ±20 mm, and the surface levelness error per meter should be no more than 5 mm.
-
Drainage and Corrosion Protection During foundation construction, design should be carried out appropriately based on the dimensions and weight of the packaged substation, ensuring both the stability and durability of the foundation. Additionally, pay attention to essential treatments such as drainage and corrosion protection for the foundation.
-
Grounding system :The grounding grid of the box-type substation should be buried at a depth of more than 1 meter to reduce grounding resistance and minimize the distribution of ground voltage. The burial depth and welding requirements for the grounding system must comply with both design specifications and relevant regulatory standards.
3. Equipment Lifting and Transport
-
Lifting equipment : Use dedicated lifting equipment, and ensure the lifting points are positioned strictly according to the manufacturer’s specifications. Additionally, soft padding must be placed where the lifting slings come into contact with the sharp edges of the equipment to prevent damage to the device’s exterior casing.
-
Lifting and Transport Process When lifting large box-type substations, use a specialized crane. Before lifting, inspect the hook, ropes, and other equipment. During the lift, ensure precise command from the supervisor and steady operation by the operator, while also setting up a safety warning zone.
