Description

用于35kV变电站设备引流线带电断接作业的消弧装置的作业 方法The operation of the arc suppression device used for the live disconnection operation of the diversion line of the 35kV substation equipment method

技术领域technical field

本发明涉及变电站设备带电作业技术领域，具体涉及一种用于35kV变电站设备引流线带电断接作业的消弧装置及使用方法。The invention relates to the technical field of live operation of substation equipment, in particular to an arc suppressing device and a use method for live disconnection operation of 35kV substation equipment drainage lines.

背景技术Background technique

消弧装置是带电断接设备引流线作业时的专用工具之一，其由消弧滑车与带有一段铜导线的绝缘消弧绳组成。当对架空线路进行带电断接工作时，通常作业人员会借助绝缘软梯或绝缘斗臂车等绝缘平台以等电位方式进入到引流线附近安装消弧装置，完成此项工作后断开(或接上)引流线并远离安装地点一段距离，以确保电弧不会伤及人员。此时引流导线上的电流靠消弧绳上铜线导通，在操作消弧装置中消弧绳的2个地面工作人员的熟练配合下，其中1人快速拉动消弧绳而另1人同时放松消弧绳，依靠消弧绳上的铜线移动拉断(或接上)其所带电而产生的电弧，从而完成带电断接引流线工作。然而，当对变电站设备引流线进行带电断接工作时，上述方法已不适用。主要因为运行中的变电站设备引流线因受地面变压器、开关设备和避雷器等众多设备设施布局影响，导致绝缘斗臂车较难接近作业点，而且在挂接引流线的架空软母线导线或硬母线导线上悬挂绝缘软梯已非常困难且不安全，这时就需要作业人员根据地面设备布置方式，在构架横担上或借助如绝缘斗臂车等绝缘平台并使用相应的绝缘操作工具装拆适用于间接作业法的专用消弧装置，从而完成带电断接设备设施的引流线作业。The arc suppression device is one of the special tools for the operation of the drain line of the live disconnection equipment. It is composed of an arc suppression block and an insulated arc suppression rope with a section of copper wire. When carrying out live disconnection work on overhead lines, usually the operator will use an insulating platform such as an insulating ladder or an insulating bucket truck to enter the vicinity of the drain line to install an arc suppression device in an equipotential manner, and disconnect (or connect) after completing this work. above) drain wire and keep a certain distance away from the installation site to ensure that the arc will not hurt people. At this time, the current on the drain wire is conducted by the copper wire on the arc-suppression rope. With the skilled cooperation of the two ground workers who operate the arc-suppression rope in the arc-suppression device, one of them pulls the arc-suppression rope quickly and the other at the same time Loosen the arc-suppression rope, rely on the copper wire on the arc-suppression rope to move and break (or connect) the electric arc generated by it, so as to complete the work of disconnecting the drain wire when it is live. However, when carrying out live disconnection work on the diversion line of the substation equipment, the above method is no longer applicable. The main reason is that the running substation equipment drainage lines are affected by the layout of many equipment and facilities such as ground transformers, switchgears, and lightning arresters, which makes it difficult for the insulated bucket truck to approach the operating point, and the overhead soft bus conductors or hard busbars where the drainage lines are connected It is very difficult and unsafe to hang the insulating ladder on the wire. At this time, it is necessary for the operator to assemble and disassemble it on the cross arm of the frame or with the help of an insulating platform such as an insulating bucket truck and use corresponding insulating operating tools according to the layout of the ground equipment. The special arc suppression device of the indirect operation method can complete the operation of the drainage line of the live disconnection equipment and facilities.
