Regulators address voltage instability

The voltage regulator is essential for stabilizing voltage-type electrical equipment, which also urges us to develop more advanced voltage regulators to meet the needs of the equipment. Let's understand how important the voltage regulator is: the role of the voltage regulator is to stabilize the voltage. Unstable voltage can cause delay in production of the equipment, delay in delivery, and differences in production quality. It is a loss of reputation and even fatal injuries. It also accelerates the aging of the equipment at the same time, which will affect the service life of its equipment and even the damage of its accessories. This in turn will face the need for maintenance or update the equipment in a short time; in serious cases, it may Cause safety accidents and cause huge losses.

How to improve the accuracy of voltage transformers

In practical use, the voltage-regulating transformer cannot meet the accuracy range of some high-end users after transformation. The wide accuracy range is a major problem for voltage-regulation accuracy. Voltage-regulating transformers are also known as auto-coupled voltage regulators, which are divided into single-phase and three-phase. They have the functions of independent voltage regulation and voltage transformation. Hereinafter referred to as voltage regulators, the accuracy range of traditional voltage regulators is between 1-5%, the range is too Broad, unable to locate the exact required voltage, and cannot meet the needs of customers. In order to improve the output accuracy of the voltage regulator, the imported voltage regulator chip combined with the rotary scale adjustment technology was introduced, and the output voltage could reach 1%. The accuracy of the output accuracy has been greatly improved. The newly developed voltage regulator has also been improved in volume. The volume is 3% smaller than the original volume. Although not very large, it will be more beautiful and applicable overall

Working principle and wiring method of three-phase transformer

A three-phase dry-type transformer is a combination of three single-phase transformers of the same capacity. It has three iron core posts, each of which is wound around two coils of the same phase, one is a high-voltage coil and the other is a low-voltage coil. Coherent transformers are transformers commonly used in the power industry. Transformer connection and connection group: High-voltage windings used in domestic transformers are generally connected into Y-connections. The connection of medium-voltage windings and low-voltage windings depends on system conditions. The so-called system situation refers to the relationship between the voltage phasor of the high-voltage transmission system and the voltage phasor of the medium-voltage or low-voltage transmission system. For low-voltage distribution system, it can be decided according to the standard. In China, the voltage phasors of 500, 330, 220 and 110kV transmission systems are all in phase. Therefore, for three-phase three-winding or three-phase autotransformers with the following voltage ratios, high-voltage and medium-voltage windings must be star-shaped. Connection. In the case of a three-phase three-core core structure, the low-voltage windings can also use star connection or angle connection. It depends on whether the voltage phasor of the low-voltage transmission system is in phase or lagging with the voltage phasor of the medium-voltage and high-voltage transmission system 30 & deg; electrical angle. 500/220 / LVkV─YN, yn0, yn0 or YN, yn0, d11 220/110 / LVkV─YN, yn0, yn0 or YN, yn0, d11 330/220 / LVkV─YN, yn0, yn0 or YN, yn0, d11 330/110 / LVkV─YN, yn0, yn0 or YN, yn0, d11 Domestic 60 and 35kV transmission system voltages have two different phase angles. For example, the 220 / 60kV transformer uses YNd11 connection, and the 220/69 / 10kV transformer uses YN, yn0, d11 connection. The two 60kV power transmission systems differ by 30 & deg; electrical angle. When 220/110 / 35kV transformers are connected by YN, yn0, d11, and 110/35 / 10kV transformers are connected by YN, yn0, d11, the voltage phasors of the two 35kV transmission systems also differ by 30 & deg; electrical angle. Therefore, care must be taken when deciding the connection of 60 and 35kV windings, and the connection must meet the requirements of the voltage phasor of the transmission system. According to the relative relationship of voltage phasor, the connection method of 60 and 35kV level windings is determined. Otherwise, even if the capacity and voltage ratio are correct, the transformer cannot be used, the connection method is incorrect, and the transformer cannot be connected to the power transmission system. Domestic 10, 6, 3 and 0.4kV phasors of transmission and distribution systems also have two phases. In Shanghai, there is a 60 & deg; electrical angle between the voltage phasor of 10kV and 110kV transmission systems. At this time, a three-phase three-winding power transformer with a voltage ratio of 110/35 / 10kV and YN, yn0, and y10 can be used. Three-phase three-core core type iron core. However, it should be noted that when a single-phase transformer is connected into a three-phase group connection method, a three-phase group connected by YNy0 cannot be used. The three-phase shell-type transformer cannot be connected with YNy0. The three-phase five-column core transformer must adopt YN, yn0, yn0 connection. There must be an angular connection in the transformer. The fourth winding does not lead out. (The structure leads out when the electrical test is performed. This example). When transformers of different connection groups are operated in parallel, the general rule is that the numbers of the connection groups must be the same. When the distribution transformer is used in the mine area, the Yzn11 connection can be used. When the z connection is used, the impedance voltage algorithm is different from the Yyn0 connection. At the same time, the copper consumption of the z connection winding is more. The lightning protection performance of Yzn11 connection distribution transformer is better. The three-phase transformer cannot use the YNy0 connection method when using four rolled core frames. The above are used for domestic transformer connection. For export, appropriate connection methods and connection group numbers should be provided according to requirements. Generally, there are taps and tap-changers connected in the high-voltage winding. Therefore, when selecting a tap-changer (including on-load tap-changer and non-excitation tap-changer), you must pay attention to the transformer connection and tap-changer connection (including connection method, test voltage, rated current, each Level voltage, voltage regulation range, etc.). For the on-load tap-changer used in the on-load voltage-regulating transformer of the YN connection method, it should also be noted that the midpoint must be able to lead out.

Selection and magic of power regulator

The power voltage regulator is a voltage regulating power supply that can adjust the voltage to the load. It can call up a variety of power supply voltages suitable for electrical equipment. Therefore, with the development of the power system, the improvement of the voltage level and the increase of the transmission capacity, the power supply voltage regulator is widely used due to the small loss and low cost. So how do we choose the power regulator that suits us? It is mainly determined by the following three points. 1. Voltage range: The voltage range should meet the needs of the load equipment. 2. Rated capacity: The capacity of the power supply regulator should be higher than the total capacity of the load, especially the inductive load and the capacitive load must leave the shock margin at startup, under normal circumstances it is 30- 40%. For example, if a capacity of 40KVA is required, and it is an ordinary purely resistive load, we can choose a power regulator of 45KVA. If it is an inductive load or a capacitive load, a power regulator of 60KVA or more is used. 3. Rated current: The rated current of the power supply regulator is the current that is higher than the working voltage of the load. If it is an inductive load or a capacitive load, a 30% margin should be left. So how can power regulators work? With China's economic development, the demand for resources will continue to increase. The rational use of resources and the avoidance of waste have become an indispensable part of our lives. This is even more important for businesses. Many enterprises may have such troubles. There are many types of equipment that have different supply voltages and are not in line with the grid voltage. It is too expensive to allocate transformers one by one, and these equipments are not used often. It is especially wasteful to maintain it often. With such distress, you may choose a power supply voltage regulator to solve this series of problems, because the power supply voltage regulator has this magical function, because its feature "voltage regulation" can meet the needs of different power supply voltage equipment. And it is easy to move and easy to maintain. * Mainly it can be used in one machine to avoid waste. It is a very good choice.

The development of technology makes the transformer technology continue to rise

In recent years, China has been vigorously building infrastructure, including of course the large-scale construction of thermal power, hydropower and wind energy bases. As a result, the output of power transmission and transformation equipment has been increasing and the prospects are bright. Transformers are the main equipment of power transmission and transformation systems. Under the favorable situation of the industry, transformer manufacturers and transformer traders have grown and developed rapidly. This makes the competition intensify, coupled with the rising prices of raw materials such as silicon steel sheets. When the factory is difficult to run, and even faces closure, some people have used their brains, so a lot of good, The phenomenon of fake and inferior transformer products with fakes and fakes has caused the already fierce competition in the transformer market to become more severe, and it is a bit worthwhile. Now, with the continuous development of society, economic prosperity, the original transformer functions and many other aspects It is no longer able to adapt to the development of society. The transformer must constantly innovate technology, so that it can meet the needs of society and the development of various fields, and the transformer will have a good market environment. Under such circumstances, vigorously improving the transformer technology is the way I asked **. Only by continuously improving the technology can we improve competitiveness. Therefore, transformer manufacturers must vigorously research the transformer technology. The development of the transformer manufacturing process is mainly combined with new technology. Develop a suitable process for the characteristics of the product and the new structure, and focus on the development and application of new materials and new equipment to continuously improve the quality and reliability of the product, and continue to make technical breakthroughs in various aspects such as performance and structure. And innovation, so that we can meet the needs of various fields. We must continue to innovate in transformer technology, break through previous technical difficulties, and adapt to the development of society.
