該產(chǎn)品具有分?jǐn)嗄芰Ω?、?dòng)熱穩(wěn)定性好、電氣方案靈活、組合方便、系列性實(shí)用性強(qiáng)、結(jié)構(gòu)新穎、防護(hù)等級(jí)高等特點(diǎn)。 

GGD 交流低壓配電柜符合 IEC439《低壓成套開關(guān)設(shè)備和控制設(shè)備》及 GB7251.1《低壓成套開關(guān)設(shè)備》等標(biāo)準(zhǔn)。

GGD AC LV fixed type switchgear is applicable to the distribution system with AC 50Hz, rated working voltage 380V, rated current to 3150A below in power station, substation, plant enter-prise etc., used for power transfer, distribution and control for power, lighting and distribution devices. 

The product has characteristics of high breaking capacity, fine dynamic and thermal stability, flexible electric project, convenient combination, better serial practicability, novel structure and high protection grade etc.

It accords with the standards IEC439 “Low voltage complete switch device and control device” and GB7251.1 “Low voltage complete switch device”etc.

主要特點(diǎn)   Main feature

1. GGD 交流低壓配電柜的柜體采用通用柜形式。構(gòu)架用 8MF 冷彎型鋼局部焊接組裝而成。構(gòu)架零件及專用配套零件由型鋼定點(diǎn)生產(chǎn)廠配套，以保證柜 體的精度和質(zhì)量。通用柜的零部件按模塊原理設(shè)計(jì)，并有 20 模的安裝孔，通用系數(shù)高。 

2. 充分考慮到柜體運(yùn)行中的散熱，在柜體上下兩端均有不同數(shù)量的散熱槽孔。 

3. 按現(xiàn)代工業(yè)產(chǎn)品造型設(shè)計(jì)要求，采用黃金分割比的方法設(shè)計(jì)柜體外形和各部分的分割尺寸，使整柜美觀大方。 

4. 柜門用轉(zhuǎn)軸式活動(dòng)鉸鏈與構(gòu)架相連，安裝、拆卸方便。門的折邊處均嵌有一根山型緣膠條，關(guān)門時(shí)門與構(gòu)架之間的嵌條有一定的壓縮行程，能防止 門與柜體直接碰撞，也提高了門的防護(hù)等級(jí)。 

5. 裝有電器元件的儀表門用多股軟銅線與構(gòu)架相連。柜內(nèi)的安裝件與構(gòu)架間用滾花螺釘連接，整柜構(gòu)成完整的接地保護(hù)電路。 

6. 柜體頂蓋在需要時(shí)可拆除，便于現(xiàn)場(chǎng)主母線的裝配和調(diào)整，柜頂?shù)乃慕茄b有吊環(huán)，用于起吊和裝運(yùn)。 

7. 柜體的防護(hù)等級(jí)為 IP30，用戶可根據(jù)環(huán)境的需要在 IP20~IP40 之間選擇。

1. The body of GGD AC LV fixed type switchgear adopts universal cabinet type. Framework is assembled with 8MF cold bending bar steel through part welding. Framework components and special mating elements are matched by bar steel pointed manufactory for ensuring the precision and quality of cabinet. Components of universal cabinet is designed according to module principle,and with 20 modulus mounting hole and high universal coefficient. 

2. Completely in view of the heat rejection during cabinet running. Heat rejection slots of different quantities are installed in upper and underside both ends of cabinet. 

3. According to the requirements on mold design for modern industry products, adopting the method of golden mean ratio to design cabinet outline and parting dimensions of each part, to make the whole cabinet beautiful and decent. 

4. Cabinet gate is connected with framework with rotation axis type movable hinge. With convenient installation and disassembly. One mount type rubber strip is set in edge fold of gate. Filler rod between gate and framework has certain compression stroke when closing the gate. It can prevent gate from impacting cabinet directly and also advance the protection grade for gate. 

5. Connect the meter gate set with electrical components with framework by multistrand soft copper wire.Connect the mounting pieces inside the cabinet with framework by knurled screws.The whole cabinet constructs complete earthing protective circuit. 

6. Top cover of cabinet can be disassembled if necessary for convenience to the assembly and adjustment for main bus bar at site. Four squares of cabinet are set with slinger for hoisting and shipping. 

7. Protection grade of cabinet: IP30. User can choose within IP20~IP40 according to environmental requirements.
