原谅我误闯了你的世界 07-29 05:50

（１）装设之前，应先根据设备接地处所的位置选择合适的接地线，提前进行检查，保证接地线合格良好待用。（２）准备好所使用的工器具和安全防护用具。如：阴雨天气，应备好雨具，登高时的梯子；需在杆塔上挂设时，必须系好安全带等。（３）现场应先理顺展放好地线。因挂地线是和验电一起进行的。验明确无电压后，*作人先将接地极装好，选择挂设时合适的站立位置。如：在平台、凳子上*作时应站稳，注意人身防护，保持好接地线与周围带电设备的安全距离，特别是部分停电地点，空间距离窄小时更应注意保持安全距离。在接通导体端的整个过程中，*作人员*不得挨靠接地线金属部分。

接触轨接地线是由绝缘*作杆、接线夹、接线端子、接地软铜线几大部分组成。原理：所谓的接地就是在停电的系统或者某个基准面之间建立低阻的导电通路。怎么安装接地线呢？我们想使用它必须要懂得怎么正确的安装，首先把导线的一头接在轨接线夹上，另一端接到接触轨接线夹上，绝缘梯螺丝一定要牢固，以确保接地线不掉不下来，在工作的时候可以正常使用就行。在挂接接地线的时候要确保无电后，立即接导体端并保证接触良好，双方的连接可靠。如果不用了想拆除接地线，拆接地线的顺序要与此相反。装、拆接地线均应使用绝缘棒和戴绝缘手套。人体不得碰触接地线或未接地的导线，以防止感应触电。以上说的这些一定要禁忌，切勿触电。在装短路接地线的时候它和带电设备的距离，考虑的因素有很多，例如考虑接地线摆动的影响，其安全距离应不小于安全工作规程所规定的数值。禁止不用线夹而用缠绕方法进行接地线短路。在平时工作过程中接地线使用的注意事项：第一、在正式工作之前必须检查整套接地线，软铜线是否有断线事情，检查绞线松股，检查护套是否有破损，夹具螺丝连接处有无断裂或松动，线钩的螺旋是否正常，不符合要求应及时更换或修好后再使用。第二、挂接地线前线路必须确保没有电压电流后，在进行接地线的挂接，验电时必须使用合格的、与电压等级相符的验电器进行验电。未验电挂接地线是基层中较普遍的习惯性违章行为，而验电的目的是确认现场是否已停电，能消除停错电、未停电的人为失误，防止带电挂接地线。第三、不得将接地线随意放置，挂在运行线路中的拉线或金属管上。其接地电阻不稳定，往往太大，不符合技术要求，还有可能使金属管带电，给他人造成危害。第四、按不同电压等级选用对应规格的接地线。这也是容易发生习惯性违章之处，地线的线径要与电气设备的电压等级相匹配。第五、不准把接地棒线夹接在表面油漆过的金属架或金属板上。这是在电气设备检修场，绝缘梯所挂接地线时常见的违章现象。虽然金属与接地系统相连，但油漆表面是绝缘体，油漆厚度的耐压达10kV/mm，可使接地回路不通，失去保护作用。第六、严禁使用其它金属线代替接地线。其它金属线接触也不牢固，故障电流会迅速熔化金属线，断开接地回路，危及工作人员生命

许我看向你 07-29 06:06

挂接地线前，应带好绝缘手套，用符合电压等级的验电器验电，确认无电后应进行放电，将完整良好的接地线先紧固在接地螺丝上，再接在停电设备上，拆地线顺序相反。在配电柜中，一般接配电柜的地线铜牌!在配电柜或者配电箱中找一下，一般没有用绝缘子而是直接用导体装在柜子上的铜牌或铜端子就是地线铜牌(或地线端子。)在机房工程中，一般接等电位接地铜牌或者等电位接地端子箱。在大楼的强电间可以找到等电位端子箱，在机房的静电地板下可以找到等电位接地铜牌。
