输电线路导线悬垂线夹螺母紧固器和开口销补销器的研制与应用

由于阿拉善地区输电线路导线受风沙影响较大,而且金具产品生产不规范,使得悬垂线夹上的开口销丢失严重。而补装开口销需要停电或采用等电位作业方法处理,给企业带来较大的经济损失。因此研制了悬垂线夹螺母紧固器和开口销补销器。开口销补销器利用废旧的破销器根部与操作杆连接,前部加工为适合放置开口销的模板;悬垂线夹螺母紧固器是利用克泵扳手及破销器的根部加工而成。通过采用研制的新工具,不仅减少了工作程序、提高了工作效率,而且降低了操作人员的劳动强度,提高了输电线路运行的可靠性。

Application and Development of Suspension Clamp Nut Fastener and Cotter Pin Mending Device for Transmission Line

The transmission line conductors were affected by the sandstorm in Alashan, and metal fitting products were not standardized, so that the cotter pins on the suspension clamp lost seriously. Supplementary cotter pins installation required cutting power supply or equipotential treatment which affected the economic benefits of the company, thus the suspension clamp nut fastener and cotter pin mending device were developed. Cotter pin mending device connected the root of the pin puller and the operating lever, the front of the pin puller was processed to suit for placing cotter pins with reflector; suspension clamp nut fastener utilized gram pump wrench and the root of the pin cutter. By using the new-developed tool, it can not only reduce working programs and improve word efficiency, but also reduce the intensity of operation crews, eventually enhance reliability of the transmission lines.
