Electricity accompanies the tropical fault detection technology method

　　With the development of modern industry, pipeline heat preservation, anti-freezing and other problems are more and more attention. Among the many solutions, electric accompanying heat tape has gradually become the preferred solution because of its unique advantages and wide range of application fields. However, electric accompanied by tropical in the process of using, due to various reasons may appear fault, affect its normal operation. Therefore, the research and application of electric accompanying tropical fault detection technology method is particularly important.

　　In this paper, we will discuss the electric accompanied by the tropical fault detection technology method in detail.

　　First, the importance of electric accompanied by tropical fault detection

　　Electric accompanied by tropical in the use process, due to various reasons, may appear fault, affect its normal operation. For example, the electric accompanied by the tropical may be because of the influence of the external environment, there is a broken line, short circuit, grounding and other faults; May also be because of improper human operation, there is overheating, burning and other problems. These problems will not only affect the normal operation of electric accompanied by tropical, but also may lead to the pipe insulation effect decline, and even cause safety accidents. Therefore, the importance of electric accompanied by tropical fault detection is self-evident....

　　Second, the electric accompanies the tropical fault detection technology method

　　1. Wire finding method

　　Wire finding method is a traditional electric accompanied by tropical fault detection method. The method is mainly through the measurement of electric accompanied by tropical resistance to ground or phase to judge the location of the fault point. Specific operation steps are as follows: first of all, will be accompanied by tropical from the middle of the disconnection; Then, from the disconnection of the measurement of resistance to ground or phase to phase, determine the fault point in the area before and after the breakpoint; Finally, determine the scope of the region and then will be the fault of the section from the middle of the disconnection, a analogy until the fault will be confirmed in the 20cm. Although the method is simple, but the electric accompanied by tropical damage.

　　2. Disconnection search method

　　Broken wire finding method is a kind of method specially used to find the electric accompanied by the tropical broken wire fault. This method is mainly through the measurement of the electric accompanied by the tropical to the ground through the situation, to judge the location of the fault point. Specific operation steps are as follows: first of all, will be accompanied by the tropical middle insulation layer cut, will be one end of the ground; Then, with a multimeter to measure the accompanying tropical to the ground of the through situation, determine and fault point in the first half or the second half; Finally, after confirming the fault section of the middle of the insulation layer cut, and so on until you find the fault. Although the method is complicated, but the damage to the electric companion belt is small.

　　3. Cable fault detector search method

　　Cable fault detector to find method is an advanced electric accompanied by tropical fault detection method. This method is mainly use the electric accompanied by the tropical structure and cable structure similar characteristics, with cable fault instrument detector to determine the scope of the fault point, and then use the acoustic method, audio method and so on different fixed-point method for accurate fixed-point, improve the efficiency of fault finding, reduce the electric accompanied by tropical damage. The method is not only simple operation, and the electric accompanying tropical damage is small, is currently the most commonly used electric accompanying tropical fault detection method.

　　4. Insulation resistance meter detection method

　　Insulation resistance meter detection method is a kind of commonly used electric accompanying tropical fault detection method. This method is mainly through the measurement of electric accompanied by tropical insulation resistance, to judge the location of the fault point. The specific operation steps are as follows: firstly, remove the iron and insulation layer on the thermostat and explosion-proof end terminal box, remove the heat-resistant pressure-sensitive adhesive tape and aluminium foil tape, and remove the thermostat and end; then, use the insulation resistance meter to clamp any one of the two busbars at the end of the thermostat (or the end), and carry out the insulation performance test of the braided layer; finally, according to the test results, determine the position of the fault point. Although the method is complicated, but the electric accompanied by tropical damage is small.

　　Third, the electric accompanies the tropical fault detection technology method development trend

　　With the development of science and technology, the electric accompanied by the tropical fault detection technology method is also in constant progress and development. For example, in recent years, with the development of artificial intelligence technology, more and more electric accompanied by tropical fault detection equipment began to use artificial intelligence technology, to achieve the automation and intelligence of fault detection. In addition, with the development of the internet of things technology, more and more electric accompanied by tropical fault detection equipment began to use the internet of things technology, realize the fault detection of remote and network. The application of these new technologies not only improves the efficiency and accuracy of the electric accompanied by tropical fault detection, but also greatly reduces the cost and workload of fault detection.

　　To sum up, the research and application of electric accompanied by the tropical fault detection technology method has important significance for guaranteeing the normal operation of electric accompanied by the tropical, improving the heat preservation effect of the pipeline, and preventing the occurrence of safety accidents.
