结构说明 Structure Description
柜架用新型8MF冷弯型钢材拼装而成，其刚性及承载能力均达到电器元件的安装要求，高低压开关柜厂家框架上分别有按E=20mm和E= 100mm数排列的安装孔，以提高产品的装配的通用性。主母线排列在柜的上部，采用的ZMJ型母线夹为积木式组合结构，用高阻燃PPO材料热注成型，机械强度和绝缘度高，能承受有效值50kA，峰值105kA电流，热稳定冲击力长期允许温度可达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%℃.
