Principle and Application of Cable Oscillation Wave Test
Principle and Application of Cable Oscillation Wave Test
1、 Principle of cable oscillation wave test through cable oscillation wave test can not only diagnose the overall insulation of cable, but also test partial discharge and locate defects. The principle is LCR damping oscillation principle. On the basis of completing the cable pressurization, a damping oscillation voltage wave is formed through the built-in high-voltage reactor, high-voltage solid-state switch and the test cable. A sinusoidal voltage wave similar to the power frequency is applied to the test cable to excite the partial discharge signal at the potential defect of the cable. Based on the pulse current method, the partial discharge signal is detected with high sensitivity, and the detection, acquisition and upload of partial discharge signal are completed with high-speed data acquisition equipment. The single test process is about one minute, with high test efficiency and no damage to the tested cable. On the basis of obtaining the partial discharge data, the data analysis software automatically completes the cluster analysis and traveling wave positioning, which is convenient for users to comprehensively evaluate the cable state. 2、 Purpose: the cable oscillation wave test standard passes the field test to check the insulation condition and internal partial discharge condition of the cable without damaging the insulation of the cable itself, so as to evaluate the cable insulation. The high voltage unit of cable oscillation wave test can generate oscillation wave high voltage signal, and the high voltage generator can generate any high voltage of 0-30kv; For the partial discharge test device with no blind area from the partial discharge signal, there is no blind area, and it can detect the cable below 250m for partial discharge test; One laptop can be used for control; External safety control units such as operation software (Chinese / German / English version); Analysis software (Chinese / German / English version); A 7.5m high-voltage connecting line without partial discharge, with anti falling off safety design; The partial discharge under system voltage is less than 1pc III. cable oscillation wave test case analysis through the above understanding, let's talk about examples below, so that you can better understand its actual field use. Firstly, connect the test line according to the instructions, and then turn on the power supply. The waveform diagram during the test is as follows: through a waveform analysis, we found a damaged gap in the outer sheath at about 132M in the field survey, which is the cable insulation damage caused by external construction force. After disassembly, the main insulation is damaged

Common Detection Methods of Power Cable Fault Tester
Common Detection Methods of Power Cable Fault Tester
Power cable is an underground equipment. Generally, the soil layer plays a protective role for the cable. However, once a fault occurs, it is also very difficult to find it. It takes a lot of time, which is a great waste of human and material resources. In this case, it is necessary to use cable fault detection equipment, such as power cable fault tester. The initial measurement method of common fault cable is divided into control circuit bridge balance method, bottom pressure single pulse reflector method and flash detector method. In the initial measurement method of cable fault, the appropriate cable fault detector is adopted according to the different characteristics of common faults, The distance between the common fault point and the test case and the relative path of the common fault point are accurately measured and calculated by using the cable route technical document. There are three key methods of initial measurement: control circuit bridge balance method, bottom pressure single pulse reflector method and flash detector method. The method to improve the sensitivity of the galvanometer can refit the DC amplifier in front of the galvanometer, but the gain value of the amplifier is too high, resulting in serious zero drift and the bridge can not be balanced. When the working voltage of the switching power supply of the bridge rises, the compressive strength of the insulating layer of the bridge body to the ground must be relatively increased and the safety precautions for the maintenance and actual operation personnel shall be taken. When the working voltage of the switching power supply rises to a certain value, the common fault resistor is generally unstable. If the resistance of the grounding wire suddenly decreases to zero, High voltage will be applied to the bridge and the galvanometer will be damaged. Common use methods of power cable fault tester. The characteristics and provisions of the bridge method are: it is only applicable to accurately measure the server downtime in the cable line. If there are many other common fault points in the line, it can not be used. The less the jumper wire at the other end of the cable route, the higher the jumper wire. Its cross section shall be close to the cross section of the cable conductor, and the connection shall be tightened to make its contact resistance close to zero. When raising the experimental working voltage for fault test of high resistor grounding device, be sure to give a very safe prompt. After the common fault burn through equipment is used to convert the common fault of flashover into the common fault of grounding device, the power bridge method shall be used for accurate measurement immediately, so as to prevent the insulation layer from being repaired and the common fault point from being closed again. In addition, it is not necessary to burn the resistance of the grounding wire of common faults too low, so as to prevent the difficulty of producing too little sound when using the precise measuring point method. The bottom pressure single pulse reflector method, commonly known as the single pulse method, uses the basic principle of the radio wave reflector caused by the mismatch of wave impedance when the differential signal is dispersed in the cable line. The time of the single pulse wave reflector and the wave speed of the cable are measured on the digital oscilloscope to clarify the distance between the cable fault points. In general, the characteristic impedance in the cable line is not matched with the right point. In addition to the disconnection (lead) of the electrical conductor, short circuit fault and common faults of the grounding device, there are all points with uneven characteristic impedance at the cable joint and where the cable crosses the metal material pipeline, which will also cause the reflection surface of the wave. Be sure to identify them carefully during detection. Especially when the resistance of the grounding wire exceeds about 2 3 times of the wave impedance of the cable, the fluctuation amplitude of the reflecting surface is small, and it is impossible to identify common fault points. The single pulse method is most suitable for measuring the common faults of disconnection. In addition, it is also suitable for measuring the resistance of grounding wire less than 100 & omega; Faulty cable.

Cable Identifier Manufacturers Popularize Science on Information Security of Power System
Cable Identifier Manufacturers Popularize Science on Information Security of Power System
China's science and technology are developing continuously and its economy is growing steadily. In this environment, the development speed of China's power industry is not the same as before. However, in today's society, facing the increasing demand for power in people's production and life, the power industry can ensure people's power consumption only by doing a good job in safe production. Now let the cable recognizer manufacturer popularize some knowledge about power system information security. In recent years, with the rapid development of power grid, especially power grid dispatching automation system, power dispatching control business has become the lifeblood of power system. According to the security protection regulations of power grid, power plant computer monitoring system and dispatching data network, the power control system must be effectively and safely isolated from the office automation system. The above-mentioned isolation means that the dispatching data network used by the power control system must be physically isolated from the public information network and the Internet, and a national power system information security protection system, security responsibility system and security joint defense system must be gradually established. The goal of power grid information security is to prevent the power grid, power plant computer monitoring system and dispatching data network from being attacked, prevent power system accidents caused by attacks, ensure the safe, stable and economic operation of power system, and protect the safety of important national infrastructure. Therefore, building the security protection system of dispatching automation system has become an important task of power grid dispatching automation in the future. Power grid information security has become an important link in the production, operation and management of power enterprises. 1、 Security protection scheme of main station of network dispatching automation system security protection strategy of main station of network dispatching automation system. Security zoning, network dedicated, horizontal isolation and vertical authentication are the basic strategies for security protection of power secondary system. Its core idea is two isolation, namely, effective and safe isolation between control system and office automation system, and physical isolation between dispatching data network, public information network and Internet. 2、 The basic principle of security protection of power real-time data network system. In theory, although the power real-time data network system with absolute security and confidentiality can not be established, if some reasonable principles are followed at the beginning of construction, the corresponding security and confidentiality will be greatly improved. When designing the security mechanism of power data network, we should follow the following principles from the perspective of Engineering Technology: among them, the integrity principle of network information security system comprehensively considers the factors such as security protection, monitoring and emergency recovery. Because the security and confidentiality of network information can not be guaranteed, it is required that when the network is attacked and damaged, the service of the network information center must be restored as soon as possible to reduce losses. Therefore, the security protection mechanism, security monitoring mechanism and security recovery mechanism of information security system should be included. Principle 2: Barrel Principle of security and confidentiality; It is necessary to consider the balance and comprehensive security protection of network data and information. The cable identifier manufacturer believes that it is a necessary prerequisite for designing the information security system to fully, comprehensively and completely analyze, evaluate and detect the security vulnerabilities and security threats (including simulated attacks) of the system.
