1. 概述
1.1 MNS系統(tǒng)為工廠組裝低壓開關(guān)裝置。技術(shù)標準符合IEC439-1、VDE660part500、BS5486part1、UTE63-410、GB7251.1 作為船用的產(chǎn)品還符合l1oyd，s Register 船用標準。
MNS系列低壓開關(guān)柜包括固定技術(shù)和抽屜技術(shù)。選用材料又分鋼板結(jié)構(gòu)技術(shù)和塑料結(jié)構(gòu)技術(shù).后者技術(shù)水平達到當(dāng)代國際水平。
MNS系統(tǒng)能適應(yīng)各種供電配電的需要，能廣泛用于陸用、電站、核電站、船用、石油平臺等各種工礦企業(yè)配電系統(tǒng)。
1.2 產(chǎn)品特點
*設(shè)計緊湊:以較小的空間能容納較多的功能單元。
*結(jié)構(gòu)通用性強、組裝靈活：以25mm為模數(shù)的C型型材能滿足各種結(jié)構(gòu)型式，防護等級及使用環(huán)境的要求。
*彩用標準模塊設(shè)計：分別可組成保護、操作、轉(zhuǎn)換、控 制、調(diào)節(jié)、測定、指示等標準單元，用戶可根據(jù)需要任意選用組裝，以200 余種組裝件可以組成不同方案的柜架結(jié)構(gòu)和抽屜單元。
*安全性：大量采用高強度阻燃型工程塑料組件，有效加強防護安全性能。
*技術(shù)性能高：主要參數(shù)達到當(dāng)代國際水平。
*壓縮場地：三化程度高，可大大壓縮儲存和運輸預(yù)制件的場地。

1. GENERAL
1.1 The modular low-voltage switchgear system MNS is a type tested factory-built switchgear assembly(FBA)in accordance withIEC4391,VDE660,part 500,BS5486 part 1,UTE63-410.The cubicle used for shipping should also conbbbb to Lloyd,s Register of shipping.
The structure of MNS switchgear is of two variwties;the fixed type and the withdrawable type,its selective materials are classified as the sheet steel structure and the plastic structure,the technology of which reaches 80s,international advanced level.
MNS system are suitable for use in all installations where electrical enetgy is generated,distributed and utiliced and are widely used as disteibution system in power station 、nubbbbb power station 、shipping、oil placbbbb and other enterprises.
1.2 FEATURES
*Compact,space saving design.
*High generalization in structure design and flexibility in makeup.The Cprofiles of sheet steel with 25mm modular interval can meet the needs of all kinds of strucrural types、protetion degrees、operating and enyironmental conditions.
*Adoption of standard module design:They xan make up avariety of standard units for protection、operating、switching、controlling、regulating、measuring and indication.The user may choose at option the relevant standard unit for assembly according to requirement.
Up to more than 200of structure parts and functional modules make it possible to make up a variety of structrue frames and drawer units for sifferent schematic requirememts.
*Adoption of arge number of the high strengthy flameresisting plastic modulars and functional partirion plates are effextive to strengthen the perbbbbance of safety protection.
*High technical characteristics,main bbbbbeters reach afairly high international advanced level.
*Reduction in space requirement for storing and transporting prefabricated parts thanks to the high degree of seriation,standardization and generalization of the structrue.
