TB-1型轴承故障检查仪是我厂设备点检工作中经常使用的监测仪。为了扩大使用范围,我们通过对仪器的工作原理、构造进行认真研究分析后发现:它除了用于运行状态下各种轴承的故障诊断监测外,还可用于电气故障的诊断监测,特别是对电气线路中经常出现的“短路”、“开路”,及“断路”故障的诊断比较准确,对电器设备的“接地”及“绝缘”情况进行监测诊断也有效。诊断电器设备中出现的“短路”或“接地”故障时,首先切断电源,然后将仪器坐标按键搬到X档位,检查仪的接地线接在被测试线路的一端,测试触头触及被测量线路的另一个端点。当检查仪读数在“危险”区域,则说明该电路中有“短路”或“接地”故障;读数在“警告”区域,说明电路中的某些线头联
TB-1 bearing fault tester is my factory equipment inspection work frequently used monitors. In order to expand the use of the scope of our instruments through the working principle of careful study and analysis found that: In addition to its operation for a variety of bearing fault diagnosis monitoring, but also for the diagnosis of electrical fault monitoring, especially for electrical The diagnosis of “short circuit”, “open circuit” and “open circuit” frequently occurring in the circuit is relatively accurate, and it is also effective to monitor and diagnose the situation of “grounding” and “insulation” of electrical equipment. When diagnosing “Short circuit” or “Grounding” fault in electrical equipment, first turn off the power and then move the instrument coordinate key to the X position. The earth wire of the tester is connected to one end of the tested circuit, and the test contact touches the measured The other end of the line. When the checker reading is in the “Danger” area, there is a “short circuit” or “ground” fault in the circuit; the reading is in the “Warning” area, indicating that some of the line headers in the circuit
