0.4kV低压开关柜标准化定制技术研究

Research on Standardized Customization Technology of the 0.4 kV Low-Voltage Switchgear

0.4kV低压开关柜在电力系统发生故障时可将故障设备从电网中快速切除,其标准化定制程度制约着配电网设备标准化设计定制的建设工作。以型号为SLVA-2500/Z001的配电组柜为研究对象,通过元器件选型、结构设计、一二次接插件、绝缘材料等关键件的选取,并借助于三维建模及仿真,经实际样柜生产及型式试验,验证了其整体方案的可行性和合理性。

The 0.4kV low-voltage switchgear can quickly remove the faulty equipment from the power grid when the power system fails.The degree of standardization and customization restricts the construction of standardized design and customization of distribution network equipment.In this paper,the distribution cabinet model SLVA-2500/Z001 is taken as the research object.Through the selection of key components,structural design,primary and secondary connectors,insulation materials and other key parts,and 3D modeling and simulation,the feasibility and rationality of this overall scheme is verified by test of the actual sample cabinet production and testing institution.
