With the continuous development of science and technology in our country, intelligent technology has been applied in many equipment to control it in an orderly way, so as to improve the overall work efficiency. It is self-evident that switch cabinet is the main control device in the power system. In the development of sensing technology, computer technology and communication technology, people also realize the feasibility of intelligent switch technology, so as to improve the application efficiency of switch controller and ensure the safe and stable operation of the power system. Here are some suggestions. The analysis is expected to provide some reference for the relevant people. For the intelligent controller of power switch, its core is the application of intelligent technology, such as communication technology, data processing technology and computer technology. On the basis of the original power switch cabinet, it has been rationally improved, and part of the performance of the controller has been optimized, so that it can be intellectualized and automated in practical application. On this basis, the application of these advanced technologies also greatly improves the security and stability of these controllers, which is conducive to their future development. For the use of intelligent controller in switch cabinet, its remarkable function is to monitor the power system. It is clear to all in the industry that the circuit is a very important component in the power system. If the internal fault of the component occurs, it will lead to the decline of power supply quality and the actual power supply efficiency to a large extent.
This situation can be analyzed carefully by technicians. Intelligent controller can be installed in circuit breaker. In the actual operation process, the intelligent controller can accurately monitor the current flow through the circuit breaker, magnetic field structure, contact wear, number of switches, collect data and information from these aspects, and accurately use the circuit breaker. Life, current operation and so on are judged comprehensively to ensure the safe and effective operation of power system and circuit breaker. In the process of data monitoring, not only the current and voltage data can be monitored, but also the capacitance data can be collected. If the capacitance problems occur and the data changes seriously during the operation of the system, the circuit breaker will not work properly, which will directly affect the quality of power supply in the whole power system. The intelligent controller of power switch cabinet should be reasonably used to effectively monitor the switching capacitance and the switching capacitance. On this basis, it should be handled in time to ensure the normal work of circuit breaker. For the controller, its basic function is the operation function.
Using the control of the module and the related automatic monitoring module, it can fulfill its only operation function. In the automatic monitoring module, it can monitor the capacitance level, the closing voltage, the circuit breaker and so on very well. If abnormal situation is found, it can monitor. The measurement system will give an alarm, and in the detection and processing module of the controller center, the corresponding operation commands will be issued, so as to directly carry out intelligent control.
For example, in actual use, combined with the actual situation, the number of synchronous closing of circuit breaker can be adjusted to ensure its accuracy and synchronization, which can reduce the probability of no-load situation of the system very well, and ultimately ensure the safe and stable operation of the power system and circuit breaker, prolong the service life of each component, find problems and problems. Times police, to win time for maintenance personnel, to avoid further expansion of the problem. For the intelligent controller in the power switch cabinet, it belongs to its protection device, which can effectively protect the circuit breaker of the power system. At the same time, the device is also its technical core. Therefore, in practical application, the relevant technical personnel must consider the intelligent controller comprehensively and master its protection and control functions. In addition, In the design process, we should introduce the current advanced technology, optimize the system design, improve its practicability, thermostatic element and ultimately realize the functions of automatic monitoring, intelligent operation and active protection of the intelligent controller of the power switch cabinet. In the process of design, these design functions and principles must be guaranteed, otherwise the market demand can not be met. The module of intelligent switch controller is shown in Figure 2. In the design of this aspect, the sensitivity of the sensor should be taken into account. In the process of use, the sensor can monitor the parameters of voltage and current signals very well. In the application, the program should be set up beforehand, and the upper limit value should be set reasonably. If the change of signal parameters exceeds the standard range, especially in different links. Characteristic signals can be effectively monitored and fed back, and a reasonable judgment of the system’s own situation can be made to ensure the safety and reliability of the system. Figure 3 is the principle of the structure design of the automatic monitoring unit, which I hope can be referred for analysis. In the design process, the intelligent operation unit should also be designed to ensure the rationality of each structure design, mainly relying on data processing technology and computer technology, and then using the developed software to effectively receive information and data, and to process and analyze these data, to control the relevant components, and to control purposefully. The system operation makes the intelligent controller of the power switch cabinet make intelligent judgment on its running state. In many switchgear intelligent control design, MCU and CPU are also used, which leads to higher cost of controller and more complex internal circuit design. In view of this situation, special integrated circuit is introduced in the design process, and anti-interference of equipment is improved.
In addition, computer technology is also very important in the process of research and development. To strengthen the development of network control software, effectively improve the quality of controller hardware, strengthen the development and research of network software, optimize the interface, simplify the overall design, greatly reduce the complexity of the circuit, optimize the entire design process, and reduce the probability of failure. Summary: Through the above analysis of the application status and design essentials of intelligent controller for power switch cabinet, it is found that its role is very important. It can monitor the operation of each system, collect relevant data and ensure its normal operation. However, there are still some problems, such as more lines, easy problems in connection and high cost of components. It is not conducive to long-term development, so in the future design and development, we should actively take measures to solve the problem and innovate its design and application methods.
