力集中控制、方便安装维护等要求而开发的一种新型低压成套开关设备。技术标准符合IEC60439

《低压成套开关设备和控制设备》、GB7251.1《低压成套开关设备和控制设备》等标准。

GCS Low-voltage withdrawable switchgear is a new-type low-voltage complete switchgear with foreign advanced

techniques, it is meeting the requirements of loadability expansioncomputer interfacingpower-control centralization

easy assembly and maintenance.It meets the reguirements of IEC60439Low-voltage complete switch equipment

and controller》GB 7251.1《Low-voltage complete switch equipment and controller》standard.

产品特点Product feature

■装置的框架为组合式结构，基本骨架由E=20mm的KS型材组装而成。柜架的全部结构件经过镀锌

处理，通过自攻锁紧螺钉或88级六角螺栓紧固连接成基本柜架。装置内部尺寸、零部件尺寸、隔室

尺寸均按模数化(E=20mm)变化。

■柜体被分隔成三个小室，即水平母线室(在柜后部)、功能单元室(在柜前部)、电缆室(在柜下

部或柜前右边)。室与室之间用镀锌钢板或高强度阻燃塑料功能板相互隔开，各室作用相对独立;上

下抽屉功能单元之间有带通风孔的金属板隔离，有效防止电器元件因故障引起的飞弧与母线或其它线

路短路造成的事故。进出线方式分类;上进上出、上进下出、下进上出、下进下出。电缆隔室的设计

使电缆上、下均有出线通道，解决了老产品无法上出线的难题。

为降低功能单元的接插件、电缆头、分隔板的温升，设计了GCS柜专用的转接件，与同类产品比

较转接件热容量增大，温升降低。

馈电柜和电动机控制柜设有专用的电缆隔室，电缆隔室的宽度为440mm。功能单元室与电缆室的连

接通过转接件或转接铜排实现，即提高了电缆的使用可靠性，又极大地方便了用户对电缆的安装与维修。

The frame of the quipment is combination-structurethe fundamental framework is assembled by KS-profiled bar

with 20mm modulus.All structural components are treated with galvanization,and connecting up to form the

fundamental framework by self-lock bolt and 8.8 grade hexagon head tap boltThe internal size of eauipment and

the sizes of components and isolation compartments could be accordina to the change of modulus(E=20mm).

The cubicle is divided into three compartments:horizontal busbar compartment (at the rear end of a cubicle)

function unit compartment(at the front of the cubicle)cable compartment(at the bottom of the cubicle or the right-

hand of fore part of the cubicle)There have qalvanized armor plate of high strength flame retardant plastic function

boards ot part the compartments,and the function of the compartments is independent from each other.There have

metal plates with blowholes to insulate the drawers top and bottom.it effectively avoids the electric arc arise from

the fault of electric components and the accidents arise from short circuit of busbar or other circuits.Classified by

wire incoming and outgoing:incoming on top and outgoing on topincoming on top and outgoing at the bottom

incoming at the bottom and outgoing on topincoming atthe bottom and outgoing at the bottom.The desian of the

cable make it owns outgoing &incoming channel on top and at the bottom.that solves the question of without

outgoing &incoming on top for the old product.

For reducing the temperature rise of insertscable terminals and clapboardswe have designed special

transferrer for GCS switchgear,comparing with the same kind of productthe thermal capacity of thistransferrer is

increased,and the temperature riseisreduced.

There have special cable compartment is feeder switchgear and motor control switchgear,the width of it is 440mm

There adopts transferrer or transfer busbar to connect function unit compartment and cable compartment together

it improves the use reliability of cablesand makes the installation and maintenance convenience.
