With the rapid development of society, the number of electric equipment is increasing day by day. However, the aging and lagging development of power transmission and distribution facilities, as well as poor design and insufficient power supply, cause the voltage of end users to be too low, while the voltage of wire end users is often too high, which is a unique time bomb for electrical equipment, especially high-tech and precision equipment with strict voltage requirements. As a public power grid, the municipal power system is connected with thousands of various loads. Some of the larger inductive, capacitive, switching power and other loads not only obtain power from the grid, but also in turn affect the grid itself, deteriorate the power supply quality of the grid or local grids, and cause the distortion of the voltage waveform or frequency drift of the municipal power. In addition, unexpected natural and man-made accidents, such as earthquake, lightning strike, power transmission and transformation system open circuit or short circuit, will endanger the normal power supply, thus affecting the normal work of the load. Unstable voltage may cause fatal injury or malfunction of equipment, affect production, delay delivery date, unstable quality and other losses. At the same time, it accelerates the aging of equipment, affects the service life and even burns the accessories, making the owner face the trouble of needing maintenance or updating the equipment in a short time, wasting resources; Serious accidents even occur, causing immeasurable losses. Therefore, the use of voltage regulators is essential for electrical equipment, especially for high-tech and precision equipment with strict voltage requirements.
Over the years, China's electric power has developed rapidly, power supply has been tense, and the great development has brought great prosperity. The huge power construction has brought opportunities and challenges to the voltage regulator industry, which has promoted the industry to achieve great development in history. The prices of iron core materials and conductive materials used in electronic products of voltage stabilizer pictures have risen continuously, and the upstream raw materials form a seller's market. As the power user of downstream electronic voltage regulators, they can select and purchase globally, forming a buyer's market. In the middle of the electronic voltage regulator industry, only by taking the road of technological innovation can we get rid of this dilemma of being frustrated at both ends. However, in the mature electronic regulator industry, technical innovation is more difficult. But every small step of improvement can bring new ideas and new products. Take the road of technological innovation and always remember the purpose to be achieved. The electronic voltage regulator in the power supply, like all products as commodities, carries out any technological innovation, must complete specific functions under specific use conditions, and pursue the best performance price ratio. Power supply products are generally characterized by "light, thin, short and small" and are developing towards miniaturization and portability. The electronic voltage regulator must meet the requirements for volume and weight of power supply products as users. At the same time, the price of raw materials for electronic voltage regulators rose. Therefore, how to reduce the volume and weight, how to reduce the cost, become the main direction of the development of electronic regulators. China has more than 2000 units engaged in research, development and production of electronic voltage regulators, including state-owned, private and foreign-funded enterprises. Although China has considerable strength in small capacity and occupies an important position in the international market, China's technical strength is still very weak in high-capacity and ultra-high capacity regulators, which has caused the situation that China cannot enter the high-capacity and ultra-high capacity regulator market of developed countries in Europe and the United States, which will hinder the future development of China's regulator industry, It needs high attention. With the rapid development of China's national economy, the demand for electric power is also increasing. As the main equipment in the power transmission and transformation system, the voltage regulator has also been greatly developed. Failing to keep up with the pace of the market and meet the needs of users, many voltage regulator manufacturers have actively reformed and developed new products in order not to be eliminated by the market. The domestic voltage regulator industry has greatly improved the variety, level and capacity of high-voltage voltage regulators by introducing foreign advanced technology. The types of voltage regulators produced by domestic enterprises include ultra-high voltage voltage regulators, converter voltage regulators, fully sealed voltage regulators, epoxy resin dry voltage regulators, coil core voltage regulators, and combined voltage regulators. In addition, with the continuous application of new materials and new processes, domestic voltage regulator manufacturers also continue to develop and develop voltage regulators of various structural forms. Innovation will be a major development direction of the voltage regulator industry.
