Description
技术领域technical field
本发明属于柜体框架结构的设计范畴和制造领域，具体涉及一种柜框架用三维连接件。The invention belongs to the field of design and manufacture of a cabinet frame structure, and in particular relates to a three-dimensional connector for a cabinet frame.
背景技术Background technique
以20、25为模数值的C型钢作为柜体框架的主结构件即立柱，已普遍使用在国内电力系统的一次设备所用的低压配电柜中，C型钢的端面形状设计是根据ABB公司引进的MNS型低压抽出式成套开关柜柜框架立柱的端面形状而来。因原设计端面形状过于简单，组装成柜体框架后，强度及稳定性较差，满足不了大电流设备的动稳定要求。多年来C型钢的端面形状已经多次改进，C型钢做为立柱本身的强度要求已经大为改观，可以满足现有大电流设备的动稳定要求，但做为柜体的立柱、横梁、侧梁三大主构件之间的连接，基本上还停留在二维连接的方法上，即横梁与立柱连接，立柱与侧梁连接，三大主构件之间仅靠横梁端头的螺栓拉住，而上述主构件的连接也只由原引进时的冷板折弯的二维连接改为冷板冲压成型后的二维连接，虽然连接件的强度增大了，但组成柜体后三个不同方向的稳定性并未得到改善，除柜体的承载负荷能力提高不了外，对于动稳定要求100KA及以上时的大电流配电柜的使用更是满足不了强度要求。The C-shaped steel with 20 and 25 as the modulus value is used as the main structural part of the cabinet frame, that is, the column. It has been widely used in the low-voltage power distribution cabinet used in the primary equipment of the domestic power system. The end shape design of the C-shaped steel is based on ABB company The imported MNS type low-voltage withdrawable complete set of switchgear cabinets comes from the end face shape of the frame column. Because the shape of the end face of the original design is too simple, after being assembled into a cabinet frame, the strength and stability are poor, which cannot meet the dynamic stability requirements of high-current equipment. Over the years, the shape of the end face of C-shaped steel has been improved many times. The strength requirements of C-shaped steel as a column itself have been greatly improved, which can meet the dynamic stability requirements of existing high-current equipment. The connection between the three main components basically stays in the two-dimensional connection method, that is, the connection between the beam and the column, and the connection between the column and the side beam. The three main components are only pulled by the bolts at the end of the beam, and The connection of the above-mentioned main components is only changed from the two-dimensional connection of cold plate bending at the time of introduction to the two-dimensional connection after cold plate stamping. The stability of the power distribution cabinet has not been improved, except that the load-carrying capacity of the cabinet cannot be improved, and the use of high-current power distribution cabinets with dynamic stability requirements of 100KA and above cannot meet the strength requirements.
