Description
技术领域technical field
本发明涉及电器线路安全防护技术领域，具体涉及一种接地线夹。The invention relates to the technical field of electric circuit safety protection, in particular to a grounding clamp.
背景技术Background technique
接地线是将已停电设备临时短路接地用的一种安全用具，其作用是对高压设备进行停电检修或进行其他工作时，防止设备突然来电和邻近高压带电设备产生感应电压对人体的危害，同时泄放断电设备的剩余电荷。The grounding wire is a kind of safety tool for temporarily short-circuiting the grounding of the equipment that has been powered off. Its function is to prevent the sudden call of the equipment and the induced voltage generated by the adjacent high-voltage live equipment from harming the human body when the high-voltage equipment is powered off for maintenance or other work. Discharge residual charge from de-energized equipment.
传统舌型压紧式接地线主要有导线端线夹、绝缘操作棒、多股裸软铜线和接电端线夹等部件组成。其中，导线端线夹为连接于接地网上或者接地端上的夹持器，通过弹簧舌片，利用弹簧压力将待接地导线夹紧在导线夹里，使接地线与导线可靠连接；短路线为接地用的多股裸软铜线，外面套有热缩硅橡胶套管，分别利用螺丝与导线端线夹、接地端线夹紧固；接地操作棒为装在导线端线夹上的绝缘手柄，用以悬挂、装卸线夹。舌型压紧式接地线使用方便，应用广泛。然而，该接地线因其自身结构原因，在悬垂竖直导线上挂装或遇大风时，连接不稳固，容易使导线从线夹滑脱，加大了检修人员的作业风险，不能很好地满足生产需要。因此，必须改进现有的短路接地线的导线端线夹，增加接地线的连接可靠性和稳定性，避免导线从线夹脱落事件的发生。The traditional tongue-shaped compression grounding wire is mainly composed of conductor end clamps, insulating operating rods, multiple strands of bare soft copper wires, and electrical terminal clamps. Among them, the wire end clamp is a holder connected to the grounding grid or the grounding end. Through the spring tongue, the spring pressure is used to clamp the grounding wire in the wire clamp, so that the grounding wire and the wire are reliably connected; the short-circuit wire is the grounding wire. The multi-strand bare soft copper wires used are covered with heat-shrinkable silicone rubber sleeves, which are respectively fastened with screws, wire end clamps, and grounding end clamps; the grounding operation rod is an insulating handle installed on the wire end clamps for hanging , Loading and unloading clips. The tongue-type compression ground wire is easy to use and widely used. However, due to its own structural reasons, the grounding wire is not securely connected when it is hung on the vertical wire or encounters strong winds, and it is easy for the wire to slip off from the wire clip, which increases the operating risk of the maintenance personnel and cannot meet the requirements Production needs. Therefore, it is necessary to improve the wire terminal clamp of the existing short-circuit grounding wire, increase the connection reliability and stability of the grounding wire, and avoid the occurrence of the event that the wire falls off from the wire clamp.
目前普遍应用变电站中的接地线夹主要有三种：螺旋线路型、双舌拉紧式、鱼口线夹，其中，螺旋压紧式接地线夹简单耐用、接触牢固良好，使用比较广泛。但它只能挂在接近垂直被接地导线上。所以一般都只能将它挂在耐张塔的跳线或直线塔的导线上，在检修跳线时，接地线就必须挂在绝缘子串外侧导线上。接地棒和绝缘子串外侧导线夹角太小，人员无法操作。折衷办法是先将两副接地挂都到耐张塔的跳线上，再用软梯或爬绝缘子串的方法，将一根接地线取下，转挂到瓷瓶串外侧导线上。由于技术人员在接地线保护范围外冒险操作，存在违规行为。即使不接触导线，也无法保证足够的安全距离；另两种接地线夹结构存在线夹与导线可能接触不牢固、受撞击或拉扯易脱落的安全隐患；这两种采用螺栓紧固式或其他具有锁止功能型式的线夹已全面停止使用。At present, there are mainly three types of grounding clamps commonly used in substations: spiral line type, double-tongue tensioning type, and fish mouth clamping type. Among them, the spiral compression type grounding clamp is simple, durable, and has good contact and is widely used. But it can only be hung on a nearly vertical grounded conductor. Therefore, generally it can only be hung on the jumper wire of the strain tower or the wire of the straight tower. When the jumper wire is overhauled, the ground wire must be hung on the outer wire of the insulator string. The angle between the grounding rod and the outer wire of the insulator string is too small for personnel to operate. The compromise method is to first connect the two sets of grounding wires to the jumper of the strain tower, and then use a ladder or climb the insulator string to remove one grounding wire and transfer it to the outer wire of the porcelain bottle string. Violations exist as technicians venture outside the protection of the ground wire. Even if the wires are not in contact, a sufficient safety distance cannot be guaranteed; the other two grounding wire clip structures have potential safety hazards that the wire clips and wires may not be in firm contact, and may fall off easily by impact or pulling; these two types use bolt fastening or other The clamps with locking function have been completely discontinued.
所以目前常用接地线夹结构不合理之处：一是，导线端挂钩与接地棒之间成一直线，接地线夹导线挂钩与接地棒之间的角度不能根据检修人员所站位置手持接地棒与导线所成角度进行相应调节；二是，线夹存在与导线接触不牢固，在碰撞、拉扯或大风作用下易发生脱落的安全隐患。一旦左右夹页张开，导线极易从弧形卡槽中脱落，导线端与地线端随即断开，接地线丧失保护功能，人员极易发生触电。究其原因，该线夹仅靠两夹叶夹住，没有锁止功能。Therefore, the commonly used grounding clamp structure is unreasonable: first, the wire end hook and the grounding rod are in a straight line, and the angle between the grounding wire clamp wire hook and the grounding rod cannot be held by the maintenance personnel according to the position of the maintenance personnel. The formed angle is adjusted accordingly; the second is that there is a potential safety hazard that the wire clamp is not in firm contact with the wire and is prone to fall off under the action of collision, pulling or strong wind. Once the left and right folders are opened, the wires will easily fall off from the arc-shaped slots, and the wire end will be disconnected from the ground wire end immediately, the ground wire will lose its protective function, and personnel will easily get an electric shock. The reason is that the wire clip is only clamped by two clip leaves and has no locking function.
因此，亟需提供一种解决上述问题的接地线夹。Therefore, there is an urgent need to provide a ground clamp that solves the above-mentioned problems.
