? 結構說明 STRUCTURE DESCRIPTION
?柜架用 8MF 冷彎型鋼材局部焊接拼裝而成,其剛性及承載能力均達到電器元件的安裝要求,框架上分別有按 E=20mm 和 E=100mm 數(shù)排列的安裝孔,以提高產(chǎn)品的裝配的通用性。主母線排列在柜的上部,采用的 ZMJ 型母線夾為積木式組合結構,用高阻燃 PPO 材料熱注成型,機械強度和絕緣度高,能承受有效值 50kA,峰值 105kA 電流,熱穩(wěn)定沖擊力長期允許溫度可達 120℃。柜體防護等級 IP3X。
?柜架為 C 型材組合式結構,結構件都經(jīng)過鍍鋅處理或敷鋁鋅板制作。通過自攻鎖緊螺釘 8.8 級六角螺釘緊固互相連接成基本框架,再按方案變化需要,加上相應的門、封板、隔板、安裝支架,以及母線、功能單元等零部件,組裝成一臺完整的裝置,裝置內(nèi)零部件尺寸、隔室尺寸,實行模數(shù)化(模數(shù)單位 E=25mm)。
? The cabinet frame is made of 8MF cold-formed steel by local welding, and its rigidity and bearing capacity meet the installation requirements of electrical components. the frame has installation holes arranged according to the number of e = 20mm and e = 100mm respectively, so as to improve the universality of product assembly. The main bus bar is arranged on the upper part of the cabinet, and the ZMJ bus bar clamp is a building block type combined structure, which is made of high flame retardant PPO material and has high mechanical strength and high insulation, can bear the effective value of 50kA and the peak value of 105kA current, and the long-term allowable temperature of thermal stability impact force can reach 120℃ . The protection level of cabinet is IP3X.
? The cabinet frame is of C-profile combined structure, and all structural members are made of galvanized or aluminum-zinc coated plates. They are fastened and connected with each other to form a basic frame by self-tapping locking screws, 8.8-grade hexagon screws, and then a complete device is assembled by adding corresponding doors, sealing plates, partition plates, mounting brackets, bus bars, functional units and other components according to the requirements of scheme changes. The dimensions of components and compartments in the device are modularized (modular unit E = 25mm).
