How to Select the Appropriate Cable Fault Tester
How to Select the Appropriate Cable Fault Tester
Cables bear the great responsibility of transmitting electric energy, so it is very important to ensure the normal use of cables. What if the cable fails? This requires the use of cable fault tester to find out the fault point, and then repaired by professional staff. Different types of equipment have different configurations, so how to select the appropriate cable fault tester? Let's have a look. As the cable fault types are divided into high resistance, low resistance, broken wire and composite faults, the cable fault detectors sold in the market are generally high and low voltage complete sets, including many components and accessories. A set of equipment components are as few as 5-6 pieces and as many as 10-11 pieces. As a cable manufacturer, it is necessary to timely locate and deal with various cable faults in the production process in the plant to ensure timely delivery of products; At the same time, we should also take into account the location of sudden cable faults after the cable laying at the customer's site or during operation. Therefore, as a cable manufacturer, when purchasing the cable fault detector, it is a complete set of high and low voltage purchase configuration, and the equipment components are 6-10 pieces. In case of direct buried cable fault location at the customer's site, the handling and transportation of the whole set of equipment must be transported by a special cable fault detection vehicle, otherwise the transportation quality of the instrument is not guaranteed. There are also some special cable fault detectors, such as the railway household coat cable fault detector. More specifically, it can be called the railway single core cable outer sheath fault tester. These two configured cable fault testers are suitable for railway. According to the characteristics of railway cable outer sheath fault, under the condition of separation of cable sheath and shielding layer, The bridge method or voltage drop method is used to initially measure the grounding fault of the cable outer sheath, and then cooperate with the special receiver to accurately find the fault point. The instrument has a built-in high-precision measurement unit. If there is a good auxiliary cable sheath, the fault is initially measured by the bridge method. Without moving the instrument to the opposite end, the test instrument can directly display the fault distance and realize rapid measurement. If there is no good auxiliary cable sheath, the fault distance of the outer sheath can also be calculated by testing both ends of the outer sheath of the faulty cable and using the resistance (voltage) comparison method, If the resistance value of the sheath per kilometer is known, the fault distance of the outer sheath can be calculated through the single end voltage drop test of the outer sheath of the faulty cable. The outer sheath transmitter and the fixed-point receiver can realize the accurate fixed-point of cable sheath grounding fault. At present, the cable fault detectors sold on the market are mainly divided into two types: one is the cable fault detector designed according to the principle of echo method: the components mainly include intelligent waveform detection analyzer, Pathfinder, DC high-voltage generator (including console and AC / DC dual-purpose high-voltage test transformer), capacitance, ball gap, pointing instrument, etc. The second is a cable fault detector designed and manufactured according to the principle of bridge method: the components mainly include fault location bridge (high and low voltage bridge), pointing instrument, path instrument, wave reflection fault location instrument, etc.
