Description

technical field [0001] The invention relates to the electrical field, in particular to a high-strength fully insulated large-current DC busbar fastening assembly. Background technique [0002] Research on the current situation of installing high-current DC busbars at home and abroad has found that most of the fastening of high-current DC busbars is fastened by channel steel or angle steel, and is insulated by porcelain insulators. However, with the development of science and technology, especially the wide application of high-current equipment, the fastening and insulation of high-current DC busbars have become particularly important. Although the previous porcelain bottle-type insulator assembly fixtures can also meet the needs, but in the actual application process It is found that the porcelain bottle insulator is not only bulky, but also has poor shear resistance. Taking the commonly used ZD-10F porcelain bottle insulator as an example, the bending failure load is 20KN, ...

Problems solved by technology

However, with the development of science and technology, especially the wide application of high-current equipment, the fastening and insulation of high-current DC busbars have become particularly important. Although the previous porcelain bottle-type insulator assembly fixtures can also meet the needs, but in the actual application process It is found that the porcelain bottle insulator is not only bulky, but also has poor shear resistance. Taking the commonly used ZD-10F porcelain bottle insulator as an example, the bending failure load is 20KN, and the glued part is prone to breakage during the operation of the equipment. If the fastening device The use of channel steel and angle steel has very high insulation requirements, and some of them will produce tip discharge phenomena. Therefore, the high-strength fully insulated and high-current DC bus fastening components composed of epoxy material clamps and epoxy insulators can solve the problem in practical applications. The occurrence of insulation and fracture problems
