Technical solutions for intelligent vacuum circuit breakers
As an important component of the power system, how to achieve the needs of intelligence, proactivity, and interactivity has become a long-term focus of attention for various research institutions and production units.
Recently, several experts and professors have expressed their views on the bottleneck problems encountered by intelligent vacuum switches. Starting from the needs of future users, in addition to its general function as a vacuum switch, intelligent vacuum switches should also have cognitive, logical thinking, discriminative ability, and execution power. That is to say, as long as the information is analyzed, processed, and published, operation instructions and detection can be carried out. As long as its functions are flexible enough, it can accurately obtain a large amount of peripheral information and efficiently react to the analysis and processing results and perform necessary operation functions. In response to the above needs, experts point out that the three key issues faced by intelligent vacuum switches are: to improve. His biggest challenge is how to utilize his cognitive abilities. Sensors must have high quality, high color fastness, insulation layer, spacing, speed, temperature and other information. Sensors can convert this information into different signals, which can accurately, reliably and flexibly reflect changes in information. In addition to having high quality and high color fastness, sensors also need to have characteristics such as operating habits, small operating space, and convenience.

The second issue in vocational skills is the implementation of logical judgment function. This is a smart administrative center, and the implementation of this function inevitably relies on modern electronic information technology, electronic information technology, and communication technology. In system software, the input includes both conscious functional input and functional feedback, as well as the control of the system's software; In the software of the system, by organizing these data, it is possible to actively identify fault states, adjust fault states, record key data, and inspect faulty components and operating conditions; On the one hand, the output execution function of the intelligent controller provides instructions, and on the other hand, the switch operation status is displayed through the system software. In addition to intelligent recognition function, intelligent controllers must have high reliability, long lifespan, and strong anti-interference ability. The third is the difficulty in achieving vocational skills, that is, the ability to achieve work.
The execution function should be strictly executed according to the operating instructions issued by the controller, using a vacuum switch to execute the switch and switch; The execution function also requires additional high strength, service life, and compact size. The current development and application of rare earth permanent magnet operating mechanisms have basically met the requirements in practical use.
