Group 1: Technology and Innovation - Solid State Transformer (SST) has significant potential in flexible interconnection and new energy integration, facing challenges in materials, devices, circuits, control, and systems [2] - The company is focusing on "intelligent" and "high-voltage direct current" trends for circuit breakers, integrating IoT and algorithms for enhanced digital operation and proactive decision-making [2] - Solid-state circuit breakers (SSCB) are being developed to meet the rigid demand for core protection devices in the context of the "dual carbon" strategy and the large-scale integration of renewable energy sources [3] Group 2: Financial Performance - The company's gross margin has experienced fluctuations due to rising raw material prices, intense industry competition, and changes in customer and product sales structures, yet remains at the industry average [2] Group 3: Product Advantages - Solid-state circuit breakers offer advantages over traditional breakers, including microsecond-level fast interruption capabilities, no arc generation, and reduced risk of damage to power systems, enhancing safety and reliability [3] - The intelligent 1U circuit breaker integrates load protection, communication self-recognition, and metering functions, reducing height from 3U to 1U to meet space requirements in communication base station cabinets [3]

Core Viewpoint - Taiyong Changzheng announced on November 17 that both silicon-based devices and silicon carbide devices have applications, depending on the specifications of different current products. The company believes that the core competitiveness of solid-state circuit breakers lies in their product design and algorithms [1] Group 1 - The company highlighted the applicability of silicon-based and silicon carbide devices based on varying current specifications [1] - The core competitive advantage of solid-state circuit breakers is attributed to product design and algorithm capabilities [1]

Core Insights - The announcement from Taiyong Changzheng on November 17 highlights the fundamental differences between solid-state circuit breakers and solid-state relays, despite both utilizing semiconductor switching technology for circuit control [1] Group 1: Product Comparison - Solid-state relays function primarily as fast execution switches controlled by electrical signals, focusing on the reliability and lifespan of load circuit operations [1] - Solid-state circuit breakers serve as intelligent protection devices with real-time monitoring and fault diagnosis capabilities, designed to automatically detect and interrupt overloads and short circuits within microseconds, emphasizing system-level safety and fault current limiting [1] - Solid-state circuit breakers can also fulfill the functions of solid-state relays due to their high electrical lifespan characteristics [1]

Group 1: Solid State Circuit Breakers (SSCB) - SSCBs are not strictly necessary components in HVDC Panama power systems but are becoming key technology choices due to their high speed, reliability, and long lifespan [2] - SSCBs can achieve microsecond-level interruption speeds, effectively matching the rapid rise of fault currents in DC systems, thus preventing fault propagation [2] - The high operational cycle capability of SSCBs, up to one million cycles, reduces long-term maintenance costs and enhances the reliability of power supply from input to load [2] Group 2: Static Transfer Switches (STS) - STS devices are based on power electronics technology, enabling extremely fast switching (usually in milliseconds or microseconds) between two independent power sources [3] - The core value of STS lies in "rapid switching" and "high reliability," making them suitable for critical loads that cannot tolerate power interruptions, such as communications data, rail transportation, and healthcare [3] Group 3: Financial Performance and Market Conditions - The company's gross profit margin has shown fluctuations due to rising raw material prices, intensified industry competition, and changes in market customer and product structures [3] - Despite these challenges, the company's gross profit margin remains at the industry average, and it is actively pursuing cost reduction and efficiency improvement through technological innovation and process optimization [3] Group 4: Product Specifications and Comparisons - The company utilizes both silicon-based and silicon carbide devices for SSCBs, depending on the current specifications of the products [3] - The core competitiveness of SSCBs lies in product design and algorithms rather than just the materials used [3] - SSCBs differ fundamentally from solid-state relays in their core functions and design goals, with SSCBs focusing on real-time monitoring and fault diagnosis capabilities [3]

证券日报网讯中熔电气（301031）11月14日在互动平台回答投资者提问时表示，公司E-fuse产品还在研 发进程中。固态断路器未来并不会形成对熔断器的替代。在现有电路系统之中，机械式断路器和熔断器 是相互配合的作用。而固态断路器功能本质上是替代机械式断路器。固态断路器虽然有一定优点，但在 体积、成本、通流发热等方面都高于机械式断路器，更远高于熔断器，且短路耐受能力较机械式断路器 弱，短路分断能力不如熔断器。熔断器为一次性保护元件，它是在应对短路等极端故障时的最后防线。 在数据中心电源中，有很多级保护存在，从高压交流到多级直流支路，储能回路等，固态断路器可能在 一定位置应用是有一些优势的，而在一些位置并不适合。熔断器因其与生俱来的被动式、高可靠的保护 特性、高分断能力、小体积等优势，其作为安全底线的价值不仅不会消失，反而可能更加重要。中熔电 气将持续巩固和深化在传统电力熔断器市场的领先地位，同时积极拓展其他新兴产品，并紧密跟踪固态 断路器等前沿技术。 ...
