摘要
为了提高配电网供电可靠性,针对目前6～10kV配电系统中线路支线和配电变压器普遍采用的跌落式熔断器,存在的在频繁大风地区易出现接线端子与上、下引线间铜铝过渡设备线夹或铜铝过渡线鼻子易发生断裂缺陷的现象,根据多年的现场应用经验总结,研制了一种跌落式熔断器接线端子的设计方案,经在多个现场供配电线路中实用,应用效果表明,可极大地提高施工效率,提高供电线路运行可靠性。
In order to improve the reliability of distribution network power supply, a design scheme for development of new type terminal block of drop-out fuse was made according to the experience in view of the fracture defects during the use of drop-out fuses whivh are widely used in branch lines and transformers of 6-10 kV electric distribution systems at present. In some regions where there are strong winds frequently, it occurs commonly that the wire clamps of the equipment or the wire noses of the copper-aluminium transition wires which connected to the fuses are fractured. The new type terminal block of drop-out fuse has been used in many distribution lines. It improved the construction efficiency and the operational reliability of the electric supply lines.
