数据中心SST的核心配件--固态断路器

Core Insights - The article discusses the rapid advancements in HVDC (High Voltage Direct Current) and SST (Solid State Transformer) technologies, highlighting the increasing interest in power export and the implications of recent developments in the industry [1][2]. Group 1: SST Developments - NVIDIA has indicated that the SST penetration rate is expected to reach 15-20% by 2027, urging suppliers to accelerate technological advancements [1]. - Meta has reversed its previous stance against SST solutions, providing SST architecture parameters (3MW) to various manufacturers, with Eaton expected to deliver samples in Q1 next year and another domestic SST company in Q2 [1]. Group 2: Solid State Breakers - The progress of SST is faster than anticipated, with expectations for solid-state circuit breakers to significantly increase in value [2]. - Solid-state circuit breakers can achieve rapid fault current interruption in microseconds, minimizing the impact on the power grid and enhancing safety and reliability [6][7]. - When solid-state breaker technology matures and costs decrease, it will become an ideal choice for DC power system protection, offering high-speed response, long electrical lifespan, and reduced maintenance costs [7]. Group 3: Comparison of DC Protection Devices - A comparison of different types of DC protection devices shows that solid-state breakers outperform traditional mechanical breakers in terms of speed, reliability, and maintenance [6]. - Solid-state breakers do not produce electric arcs, which further reduces the risk of damage to power sources and loads [6]. Group 4: Industry Trends - The article notes the ongoing trend of power export, particularly in the context of the US power system and the recent trade framework established between China and the US [1]. - The acquisition of Power Distribution by Eaton and the introduction of liquid cooling solutions for SST are also highlighted as significant industry movements [1].
