由于配电网络绝缘水平低，在大气过电压、污秽或其他外界因素作用下易发生故障，检修工作量大，难以满足可靠供电的要求。为提高配网供电可靠性、减少停电损失、提高可靠性指标，带电作业是电力设备测试、检修、改造的重要手段，在带电作业过程中常常需要对负荷进行转移来进行故障设备的更换工作，以保证线路的持续供电，因此引流线的使用非常频繁。以往的引流线采用套筒式线夹，在挂接过程中需要将套筒拧下才能实现引流线与导线连接紧固，作业人员穿戴绝缘手套在操作过程中十分不便，且动作幅度较大，增加了作业人员在作业过程中的不安全因素和作业难度。 Due to the low insulation level of the distribution network, failures are prone to occur under the influence of atmospheric overvoltage, pollution or other external factors, and the maintenance workload is large, which makes it difficult to meet the requirements of reliable power supply. In order to improve the reliability of distribution network power supply, reduce power failure losses, and improve reliability indicators, live work is an important means of testing, repairing, and transforming power equipment. During live work, it is often necessary to transfer loads to replace faulty equipment. In order to ensure the continuous power supply of the line, the use of the drain line is very frequent. In the past, the drainage wire used a sleeve-type clamp. During the hooking process, the sleeve needs to be unscrewed to realize the connection and fastening of the drainage wire and the wire. It is very inconvenient for the operator to wear insulating gloves during the operation, and the movement range is relatively large. Increased the unsafe factors and difficulty of operation of operators in the operation process.
通过检索可知，目前有多个关于引流线夹改进的报道，但大多采用活扳子式结构，由于活扳子式结构的夹口为敞口，所以被夹持的电缆容易脱出，而且在高空也不易操作。目前尚未见既容易操作，被夹持的导线也不容易脱出的卡具式绝缘引流线夹的报道。 According to the search, there are currently many reports on the improvement of the drainage clamp, but most of them adopt the wrench structure. Since the clamp of the wrench structure is open, the clamped cable is easy to come out, and it is not easy at high altitude. operate. Have not yet seen both easy to operate at present, and the report of the clip-type insulating drain wire clamp that the clamped wire is not easy to come out yet.
