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，按順序將開關櫃放在基礎型鋼上。成列櫃就位後，先找正兩端的櫃，再在櫃下上三分之二高的位置繃上小線，逐台找正，以櫃麵為標準。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、就位找正後，按櫃固定螺孔尺寸進行固定，櫃體與櫃體、櫃體與側擋板均用鍍鋅螺絲連接。高、低壓開關櫃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，櫃前、櫃後均用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、開關櫃其相鄰兩櫃頂部水平度偏差不大於2mm，全部櫃頂部水平偏差不大於5mm，其相鄰兩櫃邊不平度不大於1mm，全部櫃麵不平度不大於5mm，櫃間接縫不大於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、設備定位後，對內部緊固件再次緊固及檢查，尤其是導體連接端頭處。櫃內接線完畢，用吸塵器櫃內雜物，保持設備內外清潔，準確標識設備位號、回路號。配電櫃安裝完成後，安裝櫃上方的的橋架。配電櫃進出電纜開孔位置由供貨方按尺寸預留。電纜敷設完成後封閉。橋架與櫃內接地母排用專用接地線可靠接地。橋架與配電箱（櫃）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.
