1. After the distribution cabinet is transported to the site, organize unpacking inspection to check whether there is deformation and paint falling, whether the instrument components are complete, and whether there are defects in spare parts and instructions, and make unpacking records.

2、根據施工圖的布置，按順序將開關柜放在基礎型鋼上。成列柜就位后，先找正兩端的柜，再在柜下上三分之二高的位置繃上小線，逐臺找正，以柜面為標準。找正時采用0.5mm墊片進行調整，每處墊片多不能超過三片。

2. According to the layout of the construction drawing, the switch cabinet shall be placed on the foundation section steel in sequence. After the rows of cabinets are in place, first align the cabinets at both ends, then stretch a small line at the two-thirds height from the bottom to the top of the cabinet, and align them one by one, taking the cabinet surface as the standard. The alignment shall be adjusted with 0.5mm gaskets, and each gasket shall not exceed three at most.

3、就位找正后，按柜固定螺孔尺寸進行固定，柜體與柜體、柜體與側擋板均用鍍鋅螺絲連接。高、低壓開關柜與預留角鋼進行牢固焊接，電纜夾層上空明露部分用花紋鋼板滿鋪，柜前、柜后均用1200mm×10mm（寬×厚）絕緣滿鋪。

3. After positioning and alignment, fix the cabinet according to the size of the cabinet fixing screw hole. The cabinet body and the cabinet body, and the cabinet body and the side baffle are connected with galvanized screws. The high and low voltage switchgear shall be firmly welded with the reserved angle steel. The exposed part above the cable interlayer shall be fully paved with checkered steel plate, and 1200mm shall be used in front and back of the cabinet × 10mm (width) × Thick) insulation shall be fully paved.

4、開關柜其相鄰兩柜頂部水平度偏差不大于2mm，全部柜頂部水平偏差不大于5mm，其相鄰兩柜邊不平度不大于1mm，全部柜面不平度不大于5mm，柜間接縫不大于2mm。

4. The levelness deviation of the top of two adjacent cabinets of the switchgear shall not be greater than 2mm, the levelness deviation of the top of all cabinets shall not be greater than 5mm, the edge unevenness of two adjacent cabinets shall not be greater than 1mm, the unevenness of all cabinets shall not be greater than 5mm, and the joint between cabinets shall not be greater than 2mm.

5、設備定位后，對內部緊固件再次緊固及檢查，尤其是導體連接端頭處。柜內接線完畢，用吸塵器柜內雜物，保持設備內外清潔，準確標識設備位號、回路號。配電柜安裝完成后，安裝柜上方的的橋架。配電柜進出電纜開孔位置由供貨方按尺寸預留。電纜敷設完成后封閉。橋架與柜內接地母排用專用接地線可靠接地。橋架與配電箱（柜）連接處采用橡膠板連接，以保護導線和電纜。

5. After the equipment is positioned, the internal fasteners shall be tightened and checked again, especially at the conductor connection end. After the wiring in the cabinet is completed, remove the sundries in the cabinet with a vacuum cleaner, keep the inside and outside of the equipment clean, and accurately identify the equipment tag number and circuit number. After the distribution cabinet is installed, install the bridge above the cabinet. The opening position of incoming and outgoing cables of the distribution cabinet shall be reserved by the supplier according to the size. Close after cable laying. The bridge and grounding busbar in the cabinet shall be reliably grounded with special grounding wire. The connection between bridge and distribution box (cabinet) is connected with rubber plate to protect wires and cables.
