Ig module is damaged due to poor heat dissipation The frequency converter makes a sudden sound during operation, and the external connection is burned. It is found that the IGBT module of the frequency converter is damaged after disassembly. Through the test of relevant boards, it is found that the IGBT trigger circuit is damaged, and other plates are normal. When removing the frequency converter board, it was found that there were a lot of oil and dust on the power board and current detection board. Turn on the fan of the heat sink of the frequency converter and see that the heat sink is also covered with oil and sundries, which completely blocks the heat dissipation channel of the frequency converter. It is inferred that the Ig module of the frequency converter is damaged due to poor heat dissipation. Maintenance process: first, completely disassemble the frequency converter, remove the heat sink of the heat dissipation channel, clean the heat sink with air pressure gas, and clean all the internal structural parts and boards of the frequency converter. Install the IGBT module. When installing the IGBT module, install it in sequence according to the requirements of the module, with appropriate torque. Repair the trigger circuit, and then install other devices in turn. After installation, conduct static test. After the static test results are good, conduct power on test and load test. The on load test is qualified and the maintenance is completed successfully. Experience summary: Based on the maintenance of several frequency converters in different models and different use environments, it is concluded that the main reason for the damage of frequency converter IGBT module is the poor use environment, which leads to the damage of electronic components on gate drive card and the blockage of heat dissipation channel of frequency converter* The easily damaged devices are voltage stabilizing tube and optocoupler. Check whether there is a problem in the driving circuit. Compare whether the resistance of each trigger terminal is consistent when power is off. The voltage waveform at the trigger end can be measured after power on. However, some frequency converters cannot be started without being installed into the module. At this time, a false load is connected in series at the p-end of the module to prevent the module from being burnt out due to touching the originator or other lines by mistake during inspection. Another important part of NTK's overall development environment is ABB automation builder tool suite. This provides an integrated development environment for various automation components used in control system projects such as NTK - from PLC, safety PLC and motion controller to driver and HMI. The tool significantly reduces software complexity and time to market. Knud Jansen, manager of mechanical control and automation products in ABB's automation products division, said: "this application illustrates the simplicity of PLC users using PLC based safety control system architecture. The key drivers of NTK are the ability to program in high-level structured text language and powerful safety code analyzer tools - providing immediate feedback to software developers when developing and testing PLC code modules." The PLC crane control system of NTK is installed in the protected cabinet in the cab. However, an "extreme condition" version of the PLC is also available, enabling users to configure enhanced functional safety PLC solutions for harsh conditions and extreme weather, such as those commonly used in some crane and winch applications. Working principle of AC servo motor The rotor inside the servo motor is a permanent magnet. The U / V / W three- phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder feedback signal of the motor is sent to the driver. The driver compares the feedback value with the target value to adjust the rotation angle of the rotor. The accuracy of the servo motor depends on the accuracy of the encoder (number of lines). 4. Servo motor? How many types? What are the characteristics of the work? A: servo motor, also known as executive motor, is used as an executive element in the automatic control system to convert the received electrical signal into angular displacement or angular speed output on the motor shaft. It is divided into DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation, and the speed decreases at a uniform speed with the increase of torque, What are the functional differences between AC servo motor and brushless DC servo motor? AC servo is better because it is controlled by sine wave and the torque ripple is small. DC servo is trapezoidal wave. But DC servo is relatively simple and cheap. Since the 1980s, with the development of integrated circuit, power electronics technology and AC variable speed drive technology, permanent magnet AC servo drive technology has made outstanding development. Electrical manufacturers in various countries have launched their own AC servo motor and servo driver series products, which have been continuously improved and updated. AC servo system has become the main development direction of contemporary high- performance servo system, which makes the original DC servo face the crisis of being eliminated. Since the 1990s, the digital servo motor drive system has been used all over the world. The development of AC servo drive in the field of transmission is changing with each passing day. Compared with DC servo motor, permanent magnet AC servo motor has the following main advantages: (1) there is no brush and commutator, so it works reliably and has low requirements for maintenance. ⑵ the heat dissipation of stator winding is convenient. ⑶ small inertia, easy to improve the rapidity of the system. (4) it is suitable for high-speed and large torque working state. (5) smaller volume and weight under the same power.

Circuit breaker refers to the switching device that can close, carry and disconnect the current under normal circuit conditions, and can close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low- voltage circuit breakers according to their scope of use. The division of high- voltage and low-voltage boundaries is relatively vague. Generally, those above 3KV are called high-voltage appliances. The circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, and protect the power line and motor. When they have serious overload, short circuit, undervoltage and other faults, it can automatically cut off the circuit. Its function is equivalent to the combination of fuse switch and over and under heating relay. Moreover, it is generally not necessary to change the parts after breaking the fault current. At present, it has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is an electrical appliance with large amount and wide range of use. working principle The circuit breaker is generally composed of contact system, arc extinguishing system, operating mechanism, release, shell, etc. In case of short circuit, the magnetic field generated by large current (generally 10 to 12 times) overcomes the reaction spring, the release pulls the operating mechanism to act, and the switch trips instantaneously. In case of overload, the current increases, the calorific value intensifies, and the bimetallic sheet deforms to a certain extent to promote the action of the mechanism (the greater the current, the shorter the action time). For the electronic type, the transformer is used to collect the current of each phase and compare it with the set value. When the current is abnormal, the microprocessor sends a signal to make the electronic release drive the operating mechanism. The function of circuit breaker is to cut off and connect the load circuit and cut off the fault circuit to prevent the expansion of accident and ensure safe operation. The high-voltage circuit breaker needs to break the arc with 1500V and current of 1500-2000a. These arcs can be elongated to 2M and still continue to burn. Therefore, arc extinguishing is a problem that must be solved for high voltage circuit breaker. The principle of arc blowing and arc extinguishing is mainly to cool the arc and reduce heat dissociation. On the other hand, arc blowing lengthens the arc to strengthen the recombination and diffusion of charged particles, and blow away the charged particles in the arc gap to quickly restore the insulation strength of the medium. Low voltage circuit breaker, also known as automatic air switch, can be used to turn on and off load circuit, and can also be used to control infrequently started motor. Its function is equivalent to the sum of some or all functions of knife switch, overcurrent relay, voltage loss relay, thermal relay and leakage protector. It is an important protective appliance in low-voltage distribution network. Low voltage circuit breaker has many protection functions (overload, short circuit, undervoltage protection, etc.), adjustable action value, high breaking capacity, convenient operation, safety and other advantages, so it is widely used. Structure and working principle low voltage circuit breaker is composed of operating mechanism, contact, protection device (various releases), arc extinguishing system, etc. The main contact of low-voltage circuit breaker is closed manually or electrically. After the main contact is closed, the free tripping mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply. In case of short circuit or serious overload of the circuit, the armature of the overcurrent release is pulled in to make the free tripping mechanism act, and the main contact disconnects the main circuit. When the circuit is overloaded, the thermal element of the thermal release generates heat, which bends the bimetallic sheet and pushes the free release mechanism to act. When the circuit is under voltage, the armature of the under voltage release is released. It also makes the free tripping mechanism act. The shunt release is used for remote control. During normal operation, its coil is powered off. When distance control is required, press the start button to power on the coil.

The shell is made of aluminum with a net weight of about 12.8kg. The device has four fans. These fans help to dissipate the heat of the machine. The machine generates a lot of heat due to its high hash rate and high power consumption. Nevertheless, the presence of four fans helps to maintain the machine at an optimal and efficient temperature by dissipating the heat generated by the machine. In order to improve heat dissipation, a1246 equipment is equipped with high temperature resistant 12038 cooler main fan. There are double fans on the front. These fans are air inlet. Each of them has seven blades, which further increases the pressure in the air contact area and deepens the air penetration into the shell while the internal dust is blown away. This special design helps prevent the accumulation of dust on the instrument panel, which may cause a short circuit due to static electricity.
