一种电缆断路点位置检测方法
摘要：
本发明涉及一种电缆断路点位置检测方法，1、在电缆中选择两根等长、等间距的均匀导线，其中，导线cd为发生断路的导线；2、将电容测试仪器或设备的两个测试表笔分别连接到导线ab和导线cd的端点a和端点c，测得导线ab和导线cd之间的分布电容C1；3、将电容测试仪器或设备的两个测试表笔分别连接到导线ab和导线cd的端点b和端点d，测得导线ab和导线cd之间的分布电容C2；4、根据公式计算得到断点位置距端点c的相对距离X：本发明解决了现有电缆故障点检测方法测试要求高、测试过程复杂的技术问题，本发明具有方便、易于操作等优点。
摘要（英）：

The invention relates to a cable open-circuit point position detecting method, including the following steps: 1. selecting two uniform lead wires with equal distances and lengths from the cable, wherein the lead wire cd is an open-circuit lead wire; 2. connecting two test pens of a capacitance testing instrument or equipment with the end point a of the lead wire ab and the end point c of the lead wire cd to measure the distributed capacitance C1 between the lead wire ab and the lead wire cd; 3. connecting two test pens of the capacitance testing instrument or equipment with the end point b of the lead wire ab and the end point d of the lead wire cd to measure the distributed capacitance C2 between the lead wire ab and the lead wire cd; 4, calculating the relative distance X from the open-circuit point position to the end point c according to the formula. The method solves the technical problems that the existing cable fault point detecting method has high test requirement and complex test process, and has the advantages of convenience and easiness in operation.
