How to Quickly Locate Cable Faults
How to Quickly Locate Cable Faults
With the different cable laying methods, the difficulty of cable fault location is gradually increasing. Among them, the positioning and search of bridge, tunnel and open laying in ditch is relatively simple, and the positioning and search of direct burial is the most difficult. When the fault nature is simple, the special cable fault location equipment can be used to locate the fault within dozens of minutes. When the fault is special, it often takes 4-5 days or even longer to locate the fault. How to quickly locate cable faults? When using echo method for cable fault location, sometimes by transferring the fault phase and wiring mode, complex faults are often transformed into simple faults, and the fault location is quickly determined to win time for the emergency repair of on-site lines, which is of great significance to the power supply user department. Low voltage power cables are generally multi-core cables. After laying and continuous use, they generally show two core and multi-core phase to phase or phase to ground short circuit faults. Sometimes, when it is detected that the fault waveform collected by a core is not ideal, it can be considered to convert the wiring to other fault cores for fault waveform detection, which often has unexpected effects. The collected and detected waveforms will become more typical and regular, so the specific location of cable fault point can be determined quickly. During the long-term on-site measurement of cable customers, it is found that the fault of small cross-section copper core directly buried power cable (35mm2 and below) and aluminum core cable may be accompanied by short-circuit and wire breaking fault at the same time. During on-site detection, changing the short-circuit fault to wire breaking fault measurement according to the different fault nature of each fault core will often double everything with half the effort. For the medium voltage direct buried power cable with extruded armor as the inner lining, the fault is mostly caused by external mechanical damage. When the insulating core fails, the inner lining may have been damaged. In case of special cable insulation fault, it is difficult to collect waveform with professional cable fault instrument. It can be considered to use the acoustic method to apply the high-voltage pulse directly between the steel strip and copper shielding layer of the cable, which will often be fixed quickly. In the field measurement process, we also found that when using the acoustic measurement method to locate the fault point of low-voltage cable, when the high-voltage line and ground wire are connected between the bad phase and the metal shield or armor, the sound is very small, so the probe can not be used to listen to the fixed point, and the effect is not ideal. Through the actual listening side on site for many times, it is found that if the distance between the discharge ball gap is appropriately increased, and the high voltage and grounding wire are connected between the two phases of the fault, the discharge sound will become larger and the fault point will be determined quickly.

Cable Fault Tester Has Become a Common Equipment for Cable Fault Detection
Cable Fault Tester Has Become a Common Equipment for Cable Fault Detection
As we all know, the rapid development of society is inseparable from the construction of infrastructure, in which the laying of power plays an important role, and the development of the whole society is inseparable from the stable operation of power. If the power failure is not solved quickly, it will have a negative impact on the regional economy, production and life. Therefore, the equipment that can quickly judge the cable fault point is extremely important. Cable fault tester is such a device. The working principle of cable fault tester is to first measure the reflected waveform of low-voltage pulse, and then use high-voltage pulse to impact the fault point passing through the cable to produce arc. When the arc voltage drops to a certain value, the medium voltage pulse is triggered to stably prolong the arc time, and then the low voltage pulse is sent out to obtain the reflected waveform of the fault point. After the two waveforms are superimposed, it can also be found that the divergence point is the corresponding position of the fault point. Because the medium voltage pulse is used to stably prolong the arc time, it is easier to obtain the fault point waveform than the secondary pulse. Compared with the second pulse method, the third pulse method does not need to select the synchronous arc burning time, and the operation is simpler. The triple pulse method adopts the double impact method to prolong the arc time, stabilize the arc, and can easily locate high resistance fault and flicker fault. The triple pulse method has advanced technology, simple operation, clear waveform and rapid and accurate positioning. It has become the mainstream positioning method of high resistance fault and flicker fault. The third pulse method is an upgrade of the second pulse method. Full length and approximate position between cable fault point and test end. The cable fault locator determines the exact location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, the working principle of power cable fault tester: the power cable fault tester is composed of three main components: power cable fault tester host, cable fault locator and cable path tester. The host of cable fault tester is used to measure the nature of cable fault. A Pathfinder is required to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault cable, the cable fault point is broken down, the cable fault is broken down, the electromagnetic wave occurs when discharging, and sound is emitted at the same time. Let the high resistance fault of the cable click through the arc. At the same time, the low-voltage pulse for measurement is added to the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and the arc surface is reflected. Due to arc combustion, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will have obvious changes in impedance characteristics, so that the waveform of lightning measurement becomes a low-voltage pulse short-circuit waveform, making the waveform particularly simple and clear. This is the so-called secondary pulse method to receive low-voltage pulse fault, which is equivalent to instantaneous short-circuit fault. The low-voltage pulse fault is combined with the traditional high-voltage pulse fault discharge method to discharge the low-voltage pulse fault to a positioning method (the secondary pulse fault is discharged into the high-voltage short-circuit fault in a positioning method, the low-voltage short-circuit fault is discharged, the high-voltage pulse fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, and the low-circuit fault is discharged.
