Cable Fault Tester
Cable Fault Tester
Cable fault detector can be seen everywhere in our daily life. Cable fault detector plays a lot of roles. Cables on the road can divert people and vehicles. The guardrail beside the river can protect people from falling into the river. The guardrail beside the lawn can protect the lawn from being trampled by animals and people. Therefore, the role of guardrail is still great, The installation of guardrail is also very important. The installation of river guardrail needs special attention. Let's follow the traffic guardrail manufacturer to see how to install River guardrail. The river guardrail is a guardrail product installed next to the river to prevent pedestrians on the river road from falling into the river. The base to be fixed during the installation of the river guardrail can only be in the original position, which may cause the base to not be fixed and lose the significance of setting the river guardrail. Simply put, it is to install the guardrail at an oblique angle, hit 2 Road nails to fix the base, and the remaining 2 nail holes are used for later maintenance. After the base of the river guardrail is fixed, the column is installed. Insert the column into the base, and then install the expansion screw. After the screw is fixed, two people need to cooperate when tightening the screw. One person holds the column to keep it vertical. When tightening the screw, the other person can tighten the screws at both ends. In this way, the column and base are installed. The next step is to install the guardrail piece. The steel connecting sleeve connects the river guardrail and the column. This is generally fixed on the column before leaving the factory, so as to reduce the on-site operation process of constructors. Align the guardrail piece with the upper and lower connecting sleeves of the column, and connect the left and right accurately. The above is the introduction to the steps of installing the river guardrail. When installing the river guardrail, we should follow the steps strictly and master the installation skills of the river guardrail, so that we can make fewer mistakes in installation and ensure the performance of the river guardrail in the process of use. We are a professional guardrail manufacturer. If you need to buy our guardrail products, you can call us to communicate with us.

Working Principle of Cable Fault Tester
Working Principle of Cable Fault Tester
Working principle of power cable fault tester consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the 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, a pathfinder shall be used 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 power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time. The working principle of the application of arc reflection method (secondary pulse method) in cable fault location: firstly, a high voltage pulse with a certain voltage level and energy is applied to the faulty cable at the test end of the cable to make the high resistance fault point of the cable break down and burn arc. At the same time, add the low-voltage pulse for measurement at the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and reflects on the surface of the arc. When arcing, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will change obviously in impedance characteristics, so that the waveform of flashover measurement becomes a low-voltage pulse short-circuit waveform, making the waveform discrimination particularly simple and clear. This is what we call the "secondary pulse method". The received low-voltage pulse reflection waveform is equivalent to the waveform of a wire core completely short circuited to ground. Superimpose the low-voltage pulse waveform obtained when releasing the high-voltage pulse and when not releasing the high-voltage pulse. The two waveforms will have a divergence point, which is the reflected waveform point of the fault point. This method combines low-voltage pulse method with high-voltage flashover technology, which makes it easier for testers to judge the location of fault point. Compared with the traditional test methods, the advantage of the secondary pulse method is to simplify the complex waveform in the impulse high-voltage flashover method into the simplest low-voltage pulse short-circuit fault waveform, so the interpretation is very simple and the fault distance can be accurately calibrated. The triple pulse method adopts the double impact method to prolong the arc burning time and stabilize the arc, which can easily locate the high resistance fault and flashover fault. The triple pulse method has advanced technology, simple operation, clear waveform and fast and accurate positioning. At present, it has become the mainstream positioning method of high resistance fault and flashover fault. The third pulse method is an upgrade of the second pulse method. The method is to first measure the reflected waveform of the low-voltage pulse without breaking through the fault point of the measured cable, then impact the fault point of the cable with the high-voltage pulse to generate an arc, trigger the medium voltage pulse when the arc voltage drops to a certain value to stabilize and prolong the arc time, and then send the low-voltage pulse, Thus, the reflected waveform of the fault point is obtained. After the superposition of the two waveforms, 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 stabilize and prolong the arc time, it is easier to obtain the fault point waveform than the secondary pulse method. Compared with the secondary pulse method, the triple pulse method does not need to select the synchronization time of arc burning, and the operation is also more simple.
