Scanner equipment is an important substation equipment of the power grid. To ensure its stable operation, it should strengthen control from design, materials, process, test, selection, operation and maintenance. Strictly follow the typical design requirements, combined with national and industrial standards, put forward design and technical requirements, and fundamentally eliminate hidden wiring problems. According to national and industry standards, as well as anti-accident measures, develop strict bidding documents for equipment to prevent unqualified products from entering the network; strengthen the supervision of the factory, strictly witness the key points of production and factory tests, and resolutely test the products for unqualified scanners. It is not allowed to leave the factory. This article will introduce you to high speed scanners.
In the linear power supply of the scanner, the voltage regulator circuit is a key component. Early scanner regulators were made up of discrete devices and the like. When the scanner's three-terminal integrated voltage regulator appeared, it was widely welcomed with its simple circuit and good performance. The scanner linear power supply is a regulated power supply with an early application and mature circuit. Its biggest advantage is that the circuit is simple, the performance is reliable, the number of components is small, the ripple is small, and the characteristics are good; the disadvantage is that the efficiency is low and the loss is large.
The main factor affecting the size and weight of the scanner is that the voltage regulator requires a radiator with a large enough area; the second is the use of a power frequency power transformer. The main reason for the low efficiency of the scanner is the application of a linear regulator. The scanner linear regulator regulates and regulates the voltage by adjusting the on-state voltage drop of the power regulator device.
Scanner industry segmentation products still have a large proportion of dedicated scanners, mainly focused on experimental scanners and analytical scanners. As far as the analysis of scanners is concerned, the current demand has not only increased in daily life and industry, but the demand has been relatively stable, and it is still the most stable market in the entire industry.
