Description
技术领域technical field
本发明属于电力设备检修领域，特别涉及在进行旁路转负荷作业过程中，对旁路引上电缆的固定。The invention belongs to the field of electric equipment maintenance, and in particular relates to the fixing of the lead-up cable of the bypass during the load transfer operation of the bypass.
背景技术Background technique
配电网在运行过程中经常需要进行检修以及项目改造等活动，在这过程中为了提高检修效率，以减少频繁以及长时间停电造成的影响，通常会选用综合不停电法进行负荷供转。基本方法就是将一条待检修线路的负荷侧通过旁路电缆临时转接到一条带电线路上，从而对待检修线路的电源测断开以进行停电检修，一方面进行了检修作业，一方面也保证了负荷侧的供电，提高了供电的可靠性。在进行旁路转负荷过程中，需要将三相旁路引上电缆搭接在线路上，为实现旁路引上电缆的固定，以往的作业过程中我们通常采用绝缘绳拴在导线上，这一固定方式存在的弊端就是当主导线线径较细时，可能造成主导线的断股甚至断线，危机了作业人员的安全以及电网的安全运行。而该发明设备解决了此项工作的问题。During the operation of the distribution network, maintenance and project transformation are often required. In order to improve the maintenance efficiency and reduce the impact of frequent and long-term power outages, the comprehensive non-stop power supply method is usually used for load transfer. The basic method is to temporarily transfer the load side of a line to be repaired to a live line through a bypass cable, so as to disconnect the power supply of the line to be repaired for power outage maintenance. On the one hand, the maintenance work is carried out, and on the other hand, it is guaranteed The power supply on the load side improves the reliability of power supply. In the process of bypass load transfer, it is necessary to lap the three-phase bypass lead cables on the line. In order to realize the fixation of the bypass lead cables, we usually use insulating ropes to tie the wires to the wires in the previous work process. The disadvantage of the fixed method is that when the diameter of the main wire is small, it may cause the main wire to be broken or even disconnected, which endangers the safety of the operators and the safe operation of the power grid. And this inventive device solves the problem of this work.
现有的作业工具或作业方法的缺点：Disadvantages of existing working tools or working methods:
在现有的技术条件下，在进行旁路转负荷作业时，通常采用绝缘绳将旁路引上电缆栓在主导线上，该方法在主导线线径较小时，极容易造成主导线的断股甚至断线，危机作业人员的安全以及电网的安全运行。Under the existing technical conditions, insulated ropes are usually used to tie the bypass lead-up cable to the main wire during the bypass load transfer operation. This method is very easy to cause the main wire to be broken when the main wire diameter is small. Units are even disconnected, which endangers the safety of operating personnel and the safe operation of the power grid.
