中间电位作业原理图解

Schematic diagram of intermediate potential operation principle

中间电位作业法是指人体处于接地体和带电体之间的电位状态，使用绝缘工具间接接触带电设备来达到其检修目的的方法。其特点是人体处于中间电位下，占据了带电体与接地体之间一定空间距离，既要对接地体保持一定的安全距离，又要对带电体保持一定的安全距离。在配电线路带电作业中，可以是既对接地体保持一定的绝缘强度，又要对带电体保持一定的绝缘强度，就可以进行作业。这是由于配电线路电压等级较低，可以通过绝缘材料包裹形成一定绝缘强度代替一定的空间距离，来达到安全作业。而输变电带电作业中，电压等级较高，没有绝缘材料能包裹形成一定绝缘强度，所以必须需要一定的安全距离来保证带电作业安全。中间电位工作原理中间电位作业位置示意图如下图所示所示。供应JFEM电机引出线 JFEM电机绕组线

The intermediate potential operation method refers to the method that the human body is in the potential state between the grounding body and the electrified body, and the insulating tool is used to contact the electrified equipment indirectly to achieve the maintenance purpose. Its characteristic is that the human body is in the middle potential, occupying a certain space distance between the electrified body and the grounding body. It should not0nly keep a certain safety distance to the grounding body, but also keep a certain safety distance to the electrified body. In the live working of distribution lines, the work can be carried out by maintaining a certain insulation strength not0nly for the grounding body, but also for the live body. This is due to the low voltage level of distribution lines, which can be wrapped by insulating materials to form a certain insulation strength instead of a certain space distance to achieve safe operation. In live working of power transmission and transformation, the voltage level is high, no insulating material can be wrapped to form a certain insulation strength, so a certain safety distance must be required to ensure the safety of live working. Working principle of intermediate potential working position diagram of intermediate potential is shown in the figure below.
