能源需求正在增长
预计到2040年，用电量将增长70%，其中一半以上的增长预计将在印度和中国[1]。随着可再生能源越来越多地成为这些国家发电的一部分，以减少损失的方式远距离传输能源的需求变得越来越迫切。然而，可再生能源可以位于需要电力的负载中心数千公里之外。在这些极端情况下，超高压（UHV）通常是传输日益增长的电力的最经济的方式，而换流变压器是交流网络和直流系统之间重要连接的关键技术。ABB开创了这一技术的先河，致力于提高电压水平，开发突破性组件，以满足在最恶劣的现场条件下传输前所未有的电力容量的严格要求。ABB在变压器设计和制造方面拥有100年的经验和专业知识，在20世纪50年代的高压直流变压器技术开发中发挥了先锋作用，为其科学家和01 Mattias Viksten Markus Pettersson高压直流变压器提供了基础。viksten@se.abb。com标记。彼得森@se.abb。com Ryan Ladd电力变压器Ludvika，瑞典ryan.ladd@se.abb.com交流母线交流侧直流侧高压直流变压器直流输电56 ABB REVIEW第01章工程师在电力传输发展中达到里程碑，从而一次又一次创造世界纪录。
高压电力变压器
ABB为1100 kV DC和1200 kV AC开发的高压电力变压器采用了最先进的技术。在提高介电性能方面取得了最显著的进展，但在所有相关领域也取得了进展，如热性能和机械性能。高压直流换流变压器高压直流换流变压器在其必须克服的挑战方面是独一无二的，以可靠和高效地运行。作为交流系统和直流转换器之间的电气和机械接口，此类变压器同时满足两个系统的要求→1.高压直流换流变压器的主要功能是将换流阀的直流电压与高压直流系统所连接的交流网络隔离。流经HVDC系统的所有电力都经过换流变压器，从而以合适的电压电平将电流输送到换流阀，该电流由AC网络电压电平转换而来。换流变压器的物理尺寸通常很大，部分原因是额定功率高，并且两个绕组都需要高度绝缘；AC绕组经常连接到高压AC电网，而DC绕组具有更高的绝缘要求。因此，介电性能对高压直流换流变压器的设计至关重要。
Energy demand is growing
It is estimated that by 2040, electricity consumption will increase by 70%, and more than half of the increase is expected to be in India and China [1]. With more and more renewable energy becoming a part of power generation in these countries, the demand for long-distance energy transmission in a way that reduces losses has become increasingly urgent. However, renewable energy can be located thousands of kilometers away from load centers that require electricity. In these extreme cases, ultra-high voltage (UHV) is usually the most economical way to transmit the growing power, and converter transformer is the key technology for the important connection between AC network and DC system. ABB pioneered this technology, committed to improving the voltage level and developing breakthrough components to meet the strict requirements of transmitting unprecedented power capacity under the worst site conditions. ABB has 100 years of experience and expertise in transformer design and manufacturing, played a pioneering role in the technical development of high-voltage DC transformers in the 1950s, and provided a foundation for its scientists and 01 Mattias Viksten Markus Pettersson high-voltage DC transformers. viksten@se.abb 。 Com tag.

High voltage power transformer
High voltage power transformers developed by ABB for 1100 kV DC and 1200 kV AC use the most advanced technology. The most significant progress has been made in improving dielectric properties, but progress has also been made in all relevant areas, such as thermal and mechanical properties. HVDC converter transformer The HVDC converter transformer is unique in the challenges it must overcome to operate reliably and efficiently. As the electrical and mechanical interface between the AC system and the DC converter, this type of transformer meets the requirements of both systems → 1. The main function of the high-voltage DC converter transformer is to isolate the DC voltage of the converter valve from the AC network connected to the high-voltage DC system. All the power flowing through the HVDC system passes through the converter transformer, so that the current is transmitted to the converter valve at the appropriate voltage level, which is converted from the AC network voltage level. The physical size of converter transformer is usually very large, partly because of the high rated power and the high insulation of both windings; AC windings are often connected to high-voltage AC power grids, while DC windings have higher insulation requirements. Therefore, the dielectric property is very important to the design of HVDC converter transformer.
