解决方案：
有了这种洞察力，ABB的工程师解决了这个问题，并提供了一个简单的解决方案：变阻器以专有的布置策略性地沿着绕组放置，以限制断路器内部可能发生的再点燃以及变压器内部谐波共振产生的任何放大电压的瞬态过电压。结合先进的绕组设计，这项工程技术可以控制可能出现的峰值电压，而无需了解连接系统的特性。TVRT技术还消除了与充油电容器相关的风险和维护。这对于依赖干式变压器来降低维护需求和降低火灾风险的数据中心尤为重要。海底应用ABB于1998年交付了世界上第一台商用海底变压器，这是一项开创性的成就。坚固耐用、免维护且异常可靠的变压器如今被常规用于为位于海底的石油和天然气工业现场设备供电：增压器、泵、压缩机、管道加热系统和变频器→3.在不久的将来，海底变压器和反应堆将用于波浪能、潮汐涡轮机和海上风电场的电网连接。没有水下电机的传统生产设施必须应对储层压力的不断下降和油田经济寿命的缩短。通常水下增压泵增加油流的压力，
GPG dry-type transformer
Raleigh, North Carolina, USA joel.a.kern@us.abb.comPablo Pacheco GPG Power Transformer C ó rdoba, Spain Pablo.Pacheco@es.abb.com Ruggero Borden abb GPG Power Transformer Monselice, Italy Ruggero.Bordon@it.abb.com 52 abb reviewed that strong switching of fast circuit breakers (such as vacuum circuit breakers and SF6 circuit breakers) can produce fast transient overvoltage in transformer windings; Some of them will cause failures, and then lead to downtime and irreparable equipment; Both are extremely expensive for network managers. ABB's Transient Voltage Resistance TM Transformer (TVRTTM) provides complete peace of mind during network switching operation → 2. TVRT can operate in any power grid because it is the only solution to control transient voltage. All its components are oil-free, which greatly reduces the installation cost and eliminates the risk of fire or leakage; This is the safest solution for people, property and the environment. The development of TVRT by ABB engineers has enabled people to realize that, unlike lightning voltage transients, switching transients are generated inside windings. In addition, the over-voltage caused by high-frequency reignition is the main source of voltage stress, rather than the voltage amplification caused by the internal resonance of the transformer.
Solution:
With this insight, ABB's engineers solved this problem and provided a simple solution: the rheostat is strategically placed along the winding with a proprietary arrangement to limit the possible reignition inside the circuit breaker and the transient overvoltage of any amplified voltage generated by the internal harmonic resonance of the transformer. Combined with advanced winding design, this engineering technology can control the possible peak voltage without knowing the characteristics of the connected system. TVRT technology also eliminates the risks and maintenance associated with oil filled capacitors. This is particularly important for data centers that rely on dry-type transformers to reduce maintenance requirements and reduce fire risks. In 1998, ABB Submarine Applications delivered the world's first commercial submarine transformer, which is a pioneering achievement. Durable, maintenance free and extremely reliable transformers are now routinely used to power on-site equipment in the oil and gas industry located on the seabed: superchargers, pumps, compressors, pipe heating systems and frequency converters → 3. In the near future, submarine transformers and reactors will be used for the power grid connection of wave energy, tidal turbines and offshore wind farms. Traditional production facilities without underwater motors must cope with the continuous decline of reservoir pressure and the shortening of economic life of oil fields. Generally, the underwater booster pump increases the pressure of oil flow,
