GGD型低壓固定封閉式成套開關設備
GGD type, Low-voltage Fixed Connection Assemblies
性能與用途
    GGD型電柜是一種安全、經濟、合理、可靠的新型低壓配電柜。電柜的主開關采用ME、DZ20等；旋轉操作式刀開關HD13BX和HS13BX，為GGD型電柜的專用設計，故大大提高了主電路的動穩定能力及安全性能。
    柜體采用通用柜的形式，構架用8MF冷彎型鋼局部焊接組裝而成。
    通用柜的零部件按模塊原理設計，并有20mm模數的安裝孔，通用系數高。
    適用于發電廠、變電站、廠礦企業等電力用戶的交流50Hz、額定工作電壓380V(660V)，額定工作電流至3150A的配電系統，作為動力、照明及配電設備的電能轉換、分配與控制之用
Functions and Applications
    GGD type electrical cabinet is a kind of safe, economical, reasonable, and reliable new-type low voltage distribution cabinet, using ME, DZ20 and so on, as its main switch. Rotary knife-switch HD13BX and HS13BX are specially designed for GGD electrical cabinet, thus greatly raise the dynamic stability ability and safety of the main circuit.
    The body adopts in-common-use type; the frame is composed with 8MF cold-bending section welding material.
    The section and elements of the in-common-use is designed according to the modular principle, it has20mmmodulus installation holes, and it has high flexibility.
    It is used in distributing system of power consumer, such as power plants, substitution, mine and industrial enterprise with AC 50Hz, rated working voltage 380V(660V) and rated working current up to3150Afor changing, distributing and control the power of the power device, illumination device and distributing equipment.
