結(jié)構(gòu)說明  Structure Description

柜架用新型8MF冷彎型鋼材拼裝而成，其剛性及承載能力均達(dá)到電器元件的安裝要求，高低壓開關(guān)柜廠家框架上分別有按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(jié)構(gòu)，用高阻燃PPO材料熱注成型，機(jī)械強(qiáng)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(dá)120C。

The frame is assembled by new type 8MF cold-bend steel with rigidity and bearing capacity meeting installation requirement of electrical components. Installation holes of E=20mm and E=100mm are provided on the frame toimprove the assembly and universality of products. Main bus is arranged on the top of the switchgear adopting ZMJ-type bus clamp in the structure of block combination. It is molded by high flame-resistance PPO material through thermal injection with high mechanical strength and insulation degree, and can bear current with effective value of 50kA and peak value of 105kA. The long-term allowable temperature of thermal stability impact force can reach 120%℃.
