Electric, there is an unparalleled status in our daily life, you can say this, if there is no electricity, our life will be a mess. However, the demand for electricity is so large, the cable will stop failure, to clear the fault in time, the relevant testing equipment is electricity, there is an unparalleled status in our daily life, you can say that if there is no electricity Will be a mess. However, the demand for electricity is so large, and the cable will be inevitable. If you want to clear the fault in time, the relevant testing equipment is essential.
Today, Xiaobian gives you some relevant knowledge about the power cable path. The power industry, due to the power cable outline failure needs to determine the location of the fault, then in order to accurately find the fault location, reduce the engineering amount of excavation and the search time, you need to use the smart cable path detector to quickly and accurately determine the cable path. There are many communication cables and TV cables in the communication industry. It also needs to be determined when it is detected when these cables need to be detected.
In engineering construction, in order to avoid the pipeline of the underground, reduce unnecessary economic losses, accelerate the progress of the project, need to accurately know the position of the underground buried pipeline. Due to the incomplete data of the past underground pipeline, the urban construction planning department has not accurately mastered the distribution of pipelines under the city, leading to many problems in the process of urban planning. In this case, it should be re-right. The underground line is detected and saved. Since the cable is buried or buried in the cable ditch, it is difficult to observe the cable path in the GIS data. Therefore, after booking the cable, the next step should be used to find the cable to the cable, find the point of the fault point. The accuracy point behind the position is meaningful.
At present, the commonly used cable path detection method is an audio induction method, that is, an audio current signal of a specific frequency is added to the cable, which generates a magnetic field signal around the cable, and uses an induction coil inductive magnetic field signal. After filtering, converted into the filter. Sound or waveforms and exhibited by headphones or displays, where there is a sound or waveform display is where the cable passes, thus detecting the cable path. When using an audio induction method to detect the cable path, you must want to get a relatively strong magnetic field signal on the ground surface, and must pass some current on the earth, otherwise the magnetic field signal may be relatively weak. The power cable path is a device that detects the underground cable path, which not only has the function of the previous old-fashioned underground cable path detector, but also has some new features, and has achieved certain technological breakthroughs 1, peak mode, this mode can be judged The cable and the operator's relative position and indicate the direction of the operator to move, and then find the buried position of the underground cable.
2, valley mode, this mode has a compass function, can determine the direction of deflection between the operator and the cable and prompt the operator to correct your own direction in time until the location of the cable is found. 3, automatic search and locking frequency function, can search for signal frequencies in the case of unknown frequency input, and then determine the access frequency and lock it. 4, current and depth display, can display real-time display of the current size and buried depth of the underground cable.
5, GPS positioning, when the location of the cable has been determined and the current geographic location information is required to record the current geographic location information, record the geographic location information of the current cable, and finally upload to the computer to manage cable data. About the related knowledge of the power cable path, Xiaobian will introduce you to you today. More exciting content, we will see you next time! .
