The low-voltage cabinet is an authorized cabinet, which means the low-voltage switchgear product produced by ABB authorized cabinet electrical complete plant. The whole mns2.0 low-voltage cabinet adopts ABB's advanced technology and is designed according to the requirements of the actual site owner. Anhui Derun Electric has been authorized to produce mns2.0 low-voltage cabinet for more than 10 years. Before each production of mns2.0 low-voltage cabinet, a small production meeting will be held to convey the details and key points of each batch of products to the assemblers. I'll let you know.

一、當(dāng)殼體生產(chǎn)完時我們要進行殼體的檢查，包括噴涂、打磨、殼體厚度、殼體各配件是否完好等。

1、 When the shell is produced, we shall conduct a comprehensive inspection of the shell, including spraying, grinding, shell thickness, whether all accessories of the shell are intact, etc.

二、當(dāng)殼體檢查完后，我們就開始領(lǐng)每臺柜子的元器件準(zhǔn)備裝配了， 在裝配之前，我們還要對各元器件進行二次檢查（收貨時次檢查），看是否有不合格的產(chǎn)品。

2、 After the physical examination of the shell, we begin to get the components of each cabinet ready for assembly. Before assembly, we also need to conduct a secondary inspection on the components (the first inspection when receiving the goods) to see whether there are unqualified products.

三、將每一個元器件按照圖紙的步驟一步一步裝配到MNS2.0開關(guān)柜中。

3、 Assemble each component into mns2.0 switchgear step by step according to the steps of the drawing.

四、不同的柜型有不同的裝配工藝，比較難裝配的是抽屜柜中的每一個抽屜，因為抽屜柜分很多單元，每一個單元的尺寸不同，元器件大小也不同。這就需要裝配工有一定的生產(chǎn)工藝水平了。

4、 Different cabinet types have different assembly processes. It is more difficult to assemble each drawer in the drawer cabinet, because the drawer cabinet is divided into many units. The size of each unit is different, and the size of components is also different. This requires the assembler to have a certain level of production technology.

五、裝配完成后，我們會有車間檢驗員對每臺柜子進行檢查，包括螺絲是否擰緊，一批次開關(guān)柜內(nèi)的接線是否一致；機械聯(lián)鎖是否正常、抽屜是否方便關(guān)合；指示燈、按鈕和導(dǎo)線顏色是否符合規(guī)范；銘牌、警告標(biāo)志內(nèi)容等位置正確等。

5、 After the assembly, we will have workshop inspectors conduct all-round inspection on each cabinet, including whether the screws are tightened and whether the wiring in a batch of switchgear is consistent; Whether the mechanical interlocking is normal and whether the drawer is easy to close; Whether the colors of indicator lights, buttons and wires meet the specifications; The contents of nameplates and warning signs are correct.

六、后一步就是出廠前調(diào)試了，此項工作由售后工程師們完成。根據(jù)國標(biāo)要求，進行每一項出廠前試驗檢測。包括外觀試驗（電氣間隙、爬電距離、絕緣電阻測試等）；通電試驗，按電氣原理圖要求，接通設(shè)計規(guī)定的電源模擬動作，進行出廠前各項測試。各項要求都符合后，方可打包出廠。保證每一批次得潤電氣出廠的MNS2.0低壓柜到達(dá)項目現(xiàn)場安裝完成后通過現(xiàn)場簡單的運行調(diào)試就可以使用了。

Six, the last step is debugging before leaving the factory, which is done by customer service engineers. Carry out each pre delivery test according to the requirements of national standards. Including appearance test (electrical clearance, creepage distance, insulation resistance test, etc.); Power on test: according to the requirements of electrical schematic diagram, connect the power supply specified in the design, simulate the action, and carry out various tests before delivery. After all requirements are met, it can be packaged and delivered. Ensure that each batch of mns2.0 low-voltage cabinets delivered by Derun electric arrive at the project site. After installation, they can be used through simple on-site operation and commissioning.
