Once there is an obstacle in the line, it will cause interruption of communication and power. If the fault cannot be detected in time and eliminated quickly, it will cause great economic loss and adverse social impact. Therefore, the cable fault tester is an important tool for maintaining various cables.
The cable fault intelligent tester adopts a variety of fault detection methods, applies the most advanced electronic technology achievements, adopts computer and special electronic technology, and combines the company's long-term successful experience in developing cable testers. A new generation of high-tech products. The all-intelligent multi-pulse cable fault tester test consists of four parts: the system host, the multi-pulse generator, the fault locator and the cable routing instrument. and daily maintenance and management of cable archives. As well as accurate testing of railway airport signal control cables and street light cable faults.
During the high-voltage flashover test, due to the extremely high working voltage, a little carelessness will cause losses to personal safety and equipment. Therefore, before the fault test, you should read the instrument manual carefully, and master the operation steps and safe wiring of the instrument. At the same time, the following points should be paid attention to during the operation: 1. During the high-voltage flashover test, the high-voltage test equipment should be operated by professionals, and the instrument should be powered off and completely discharged during wiring and adjustment. 2. One of the main features of this cable fault tester is that there is no external power supply, and the equipment is all provided by the built-in battery in the machine.
This brings great convenience to the use of the instrument and improves the safety factor. Every time you go to the field to test the cable fault, the battery voltage of the machine must be sufficient. When charging from an external power supply,“test power”The light on the switch lights up to indicate that charging is in progress.
Generally, it takes 4 hours to charge. After the battery voltage is sufficient, it can guarantee normal operation for about 6 hours. When the instrument is in use, it can be connected to the AC power supply for floating charge.
However, when conducting a high-voltage flashover test, it must be completely disconnected from the external AC mains. 3. The grounding terminal of the current sampler must be grounded reliably, otherwise the high voltage discharge path will be disconnected, and the high voltage will be induced to the tester and cause a safety hazard to the instrument. 4. Considering the safety of the tester, the working menu must be in the flashover or direct flashover state during the flashover test. If the high-voltage flashover test is performed in the low-voltage pulse state by mistake, it may damage the low-voltage pulse circuit inside the tester.
5. It should be properly grounded, that is, high-voltage equipment, and the ground wire of the current sampler must be close to the lead package of the cable. The protective ground of the tester should be connected separately from the ground wire of the high-voltage equipment. 7. There should be no discharge sparks at each connection point during the test, otherwise the test waveform will be affected.
8. The cable fault tester is a highly sophisticated electronic device. Non-professionals must not disassemble lightly. If there is any problem with the instrument, please contact the dealer or our company in time.
If the instrument is damaged due to human factors, you will lose the right to the instrument warranty. 9. When the cable fault tester wants to exit the test state and shut down, it should enter the file menu and use the“quit”The function returns to the desktop system, and then shuts down the computer according to the normal procedure. After the computer is turned off, put the“switch”Disconnect to ensure that the computer is no longer draining power.
