带电检修扳手Live maintenance wrench

技术领域 technical field

本实用新型涉及一种带电检修扳手,适用于电力系统检修技术领域。 The utility model relates to a live maintenance wrench, which is suitable for the technical field of power system maintenance.

背景技术 Background technique

目前,国家电力部门的架空线路使用一段时间后,往往需要进行检修,如110-220KV变电站一次设备(开关、CT、PT引线等)的松动,将会导致线路发热,容易引发电路故障,影响人们正常的生产生活。导致一次设备松动的原因主要有:接触面氧化;风力过大引线摇摆;螺栓质量差;线卡质量差。这些故障原因往往发生在夏季用电高峰期,事故一旦发生,需要马上停电检修处理,以一条110KV线路停电2小时为例,每处理一次故障造成的停电损失约为3万KWh。对于电力设备的检修,目前通用的的工具主要有用于紧固螺栓的检修扳手等,现有的检修扳手都是导电材质,需要停电检修;另外现有的检修扳手需要检修人员登高接近电力设备,才能进行检修,效率低,安全可靠性差。因此,迫切需要一种能够带电使用且不用登高的检修扳手。 At present, the overhead lines of the national power department often need to be repaired after being used for a period of time. For example, the looseness of the primary equipment (switches, CTs, PT leads, etc.) normal production and life. The main reasons for the looseness of primary equipment are: oxidation of the contact surface; swinging of lead wires due to excessive wind force; poor quality of bolts; poor quality of line cards. The causes of these failures often occur during the peak power consumption period in summer. Once an accident occurs, it needs to be repaired immediately. Taking a 110KV line outage for 2 hours as an example, the power outage loss caused by each failure is about 30,000 KWh. For the maintenance of electrical equipment, the current general-purpose tools mainly include maintenance wrenches for fastening bolts, etc. The existing maintenance wrenches are made of conductive materials and require power-off maintenance; To carry out maintenance, low efficiency, poor safety and reliability. Therefore, there is an urgent need for an inspection wrench that can be used with electricity and without climbing.
