Description
技术领域 technical field
本发明属于引流线保护技术领域，尤其涉及一种可以带电处理引流线线夹螺栓的工具及其带电作业的方法。 The invention belongs to the technical field of drain wire protection, and in particular relates to a tool capable of live-handling clamp bolts of drain wires and a live working method thereof.
背景技术 Background technique
引流线及其线夹在运行过程中因风的振动等因素会出现紧固螺栓松动的现象，会导致引流线和导线间存在放电现象，需要对螺栓进行紧固。在输电线路运行的过程中，人员、杆塔以及架空地线等都必须与带电导线保持一定的安全距离。根据电压等级的不同，安全距离也不尽相同。表1列出了常见输电线路电压等级对应的安全距离。 During the operation of the drainage wire and its clamp, the fastening bolts will loosen due to wind vibration and other factors, which will cause discharge between the drainage wire and the wire, and the bolts need to be tightened. During the operation of transmission lines, personnel, towers and overhead ground wires must keep a certain safe distance from live conductors. According to different voltage levels, the safety distance is also different. Table 1 lists the safety distances corresponding to common transmission line voltage levels.
表1 带电作业时人身与带电体的安全距离 Table 1 Safety distance between the person and the live body during live work
为了保证上述安全距离，不发生放电、触电等事故，现有紧固螺栓作业是基于停电条件或者带电等电位条件完成的。停电条件下主要采用的工具有：扳手、木梯等，紧固螺栓流程如下所述： In order to ensure the above-mentioned safe distance and avoid accidents such as discharge and electric shock, the existing bolt tightening operation is completed based on power failure conditions or electrified equipotential conditions. The main tools used under power failure conditions are: wrench, wooden ladder, etc. The process of fastening bolts is as follows:
首先、工作负责人向调度人员申请对作业线路进行转负荷和停电操作； First, the person in charge of the work applies to the dispatcher for load transfer and power outage operations on the operation line;
第二、作业人员通过木梯攀爬至螺栓松动处，用扳手紧固后回到地面； Second, the operator climbs to the loose bolt through the wooden ladder, tightens it with a wrench and returns to the ground;
第三、工作负责人向调度人员汇报工作完毕，恢复送电。 Third, the person in charge of the work reports to the dispatcher that the work is completed and the power transmission is resumed.
此种更换技术对于大面积紧固螺栓而言是经济有效的，但是如果仅对一处或两处紧固螺栓的话，需要在每次更换的过程中进行停电操作并重复进行作业工器具的布置，这会严重影响线路的可靠性。 This replacement technique is cost-effective for fastening bolts in large areas, but if only one or two bolts are fastened, it is necessary to perform power-off operations and repeat the arrangement of work tools during each replacement process , which will seriously affect the reliability of the line.
带电等电位条件下主要采用的工具有：扳手、软梯、屏蔽服等，紧固螺栓流程如下所述： The main tools used under charged equipotential conditions are: wrench, soft ladder, shielding suit, etc. The process of fastening bolts is as follows:
首先、工作负责人向调度人员申请对作业线路进行停用重合闸操作； First, the person in charge of the work applies to the dispatcher for the deactivation and reclosing operation of the operation line;
第二、辅助人员登杆向导线上挂好软梯； Second, the auxiliary personnel board the pole and hang the soft ladder on the guide line;
第三、作业人员穿好屏蔽服通过软梯攀爬至螺栓松动处，用扳手紧固后回到地面； Third, the operator wears the shielding suit and climbs through the soft ladder to the loose bolt, tightens it with a wrench and returns to the ground;
第四、工作负责人向调度人员汇报工作完毕，恢复重合闸。 Fourth, the person in charge of the work reports to the dispatcher that the work is completed and resumes reclosing.
此种更换技术只能用于无法停电的线路，不适合大面积或者个别几处的紧固螺栓操作，每次都要重复作业工器具的布置，这会严重影响线路的可靠性。此外，如果作业地点位于山区等地带，软梯等无法按照作业指导书的要求进行布置，更换作业将难以进行。 This kind of replacement technology can only be used for lines that cannot be powered off, and is not suitable for fastening bolts in large areas or in a few places. The arrangement of operating tools must be repeated every time, which will seriously affect the reliability of the line. In addition, if the work site is located in a mountainous area and other areas, the ladders cannot be arranged according to the requirements of the work instructions, and the replacement operation will be difficult.
