The high-voltage switchgear power-on test bench adopts separate transformer boost and DC to avoid burning the voltage regulator. It adopts digital voltage and current meter with higher precision. It adopts anodized aluminum panel, which is more resistant to dirt, wear and beauty. The high-voltage switchgear power-on test bench is widely used in the high- and low-voltage switchgear manufacturers to carry out various power-on tests before the factory. YTC1106 high and low voltage switchgear power supply test bench can provide a variety of AC and DC power supply, easy to detect the switchgear, improve work efficiency. Integrate a variety of AC and DC power supplies to facilitate the detection of switchgear and greatly improve work efficiency.
Due to the role of the high-voltage switchgear power-on test bench in the power system and its necessity for the safe and continuous power supply of the power system, the relay protection must have certain performance and characteristics. Therefore, the relay protection workers should also propose corresponding Claim. The high-voltage switchgear power-on test bench is an organic whole consisting of many complicated primary equipments and secondary protection, control, regulation, signal and other auxiliary equipment. Each device has its own unique operating characteristics and operating conditions at the time of failure. Failure of the high-voltage switchgear power-on test bench will immediately cause changes or damage to the normal operating state of the system, causing different degrees of impact on other devices and the entire system. Therefore, the work of relay protection of the high-voltage switchgear power-on test bench involves each electrical main equipment and secondary auxiliary equipment, and the working principle, performance, parameter calculation and fault status of the relay test bench for the high-voltage switchgear are required. The analysis and so on have a deep understanding, but also have extensive knowledge of production operations. In addition, there must be a clear concept for the planning and design principles of the entire power system, the basis for the development of operational methods, the theory of voltage and rate adjustment, the method of flow and stability calculation, and the principles and methods of economic dispatch and safety control.
The high-voltage switchgear power-on test bench is a comprehensive discipline. It is based on basic theories such as theoretical electrician, electrical engineering and power system analysis. It also has new theories and new technologies such as electronic technology, communication technology, computer technology and information science. close relationship. Throughout the history of the high-voltage switchgear power-on test bench, it can be seen that every major advancement in power system communication technology has led to the emergence of a new protection principle, such as high-frequency protection, microwave protection and fiber protection; The emergence of new electronic components has also caused a revolution in relay protection devices. The high-voltage switchgear power-on test bench from the electromechanical relay to the body tube protection device, integrated circuit protection device and microcomputer protection, fully illustrates this problem. At present, the protection of microcomputers and the realization of optical fiber communication and information networks are making fundamental changes in the face of relay protection technology.
Some new theories, new concepts and new methods will emerge in the design, manufacture and operation of the high-voltage switchgear power-on test bench. It can be seen that relay protection workers should pay close attention to the development of new theories, new technologies and new materials in adjacent disciplines, actively and cautiously use various new technological achievements, continuously develop the theory of relay protection and improve their technology. Level and reliability indicators improve the performance of the protection device to ensure safe operation of the power system. The high-voltage switchgear power-on test bench needs to use the theoretical knowledge of the course to analyze the system fault condition and the action of the protection device. It also needs laboratory test, digital simulation analysis, and dynamic model of the power system. Test, on-site manual failure test and commissioning under field conditions.
