| 摘 要： | 分析了采用常规平衡电桥原理的直流绝缘监察技术存在的问题,提出了采用不平衡与平衡电桥原理相结合来检测直流系统的绝缘状况,并给出了设计方法。该方法不但可以有效解决对称和不对称的直流接地,同时可以在很大程度上提高直流绝缘检测的灵敏度。 |
| 关 键 词： | 绝缘监察 平衡电桥 电压检测 |

| Abstract: | The problems of the DC insulation monitor theory adopted routine balance bridge theory were analyzed in this paper.The method based on unbalanced bridge and balance bridge principle to check direct-current system insulation situation at the same time was designed.The method can effectively resolve the problem of symmetrical and asymmetric direct-current ground connection and can improve the checking sensitiveness of ground connection electric resistance at a great extent. |
| Keywords: | insulated supervising balanced bridge voltage check |
