性能特點：
Performance characteristics:
1．功能單元采用模塊設計，結(jié)構(gòu)緊湊，可隨意組合不同模數(shù)的抽屜單元，在較小的空間內(nèi)可容納較多的功能單元。抽屜單元互換性強。
1. The functional unit adopts modular design with compact structure. It can combine drawer units of different modules at will, and can accommodate more functional units in a smaller space. The drawer unit has strong interchangeability.
2．柜內(nèi)按一、二次回路的功能劃分為裝置抽屜隔室、電纜隔室、母線隔室以及二次端子隔室。隔室之間采用接地的鋼板和獨特設計的、阻燃的絕緣功能板進行間隔。無裸露帶電體，確保了設備運行和人員的人身。
2. The cabinet is divided into device drawer compartment, cable compartment, bus compartment and secondary terminal compartment according to the function of primary and secondary circuits. The compartments are separated by grounded steel plates and specially designed flame-retardant insulating functional plates. There is no exposed charged body, which ensures the equipment operation and personal safety of personnel.
柜體結(jié)構(gòu)特征
Cabinet structure features
1）外殼防護等級不低于IP40，且具有良好的自然通風結(jié)構(gòu)。用于嚴酷環(huán)境其防護等級可達到IP54。
