Recently, reporters learned from SPIC Shandong Nuclear Power that Haiyang Nuclear Power Units 1 and 2 in Yantai have been operating safely and stably for five years, with a cumulative power generation of 104.3 billion kWh. During these five years, key equipment such as isolating switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses and arresters have played an indispensable role in power transmission and distribution, ensuring the stable supply and safe use of power. .
These equipments play a vital role in the Haiyang Nuclear Power Project. For example, the isolation switch plays an important role in isolating the power supply during the maintenance of the power system, while the vacuum circuit breaker can quickly cut off the fault current and protect the power system from damage. Transformers are responsible for regulating voltage to ensure that power can be transmitted safely and efficiently. As a key equipment for power distribution, switchgear can control and protect the normal operation of circuits. The drop-out fuse will automatically blow when the current is too large and play the role of short-circuit protection. Lightning arresters can effectively prevent lightning damage to power facilities.
In addition to their role in electricity transmission and distribution, these devices also play an important role in nuclear power heating. Haiyang Nuclear Power not only provides stable heating for 400,000 residents in Haiyang and Rushan, setting a world record for the heating capacity of a single nuclear power base, but also achieves zero-carbon emission heating through advanced nuclear energy comprehensive utilization technology. In this process, equipment such as isolation switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses and lightning arresters play a key role in ensuring the stable operation of the heating system.
It is understood that Haiyang Nuclear Power Units 1 and 2 are the world's first third-generation nuclear power units and are projects supporting my country's third-generation nuclear power independence. Relying on the successful construction and operation of these units, Shandong Nuclear Power has accelerated the independent research and development and innovation of third-generation nuclear power technology, helping my country form a complete, safe and economical third-generation nuclear power industry chain. In this process, equipment such as isolating switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses and lightning arresters also play an important role.
In addition, Haiyang Nuclear Power Units 3 and 4 are under steady construction and are scheduled to be fully operational in 2027. After the entire base's eight units are fully completed, the annual power generation capacity will reach approximately 80 billion kilowatt-hours, which can meet the daily electricity needs of residents in Shandong Province for approximately one year. The stable operation of these units is also inseparable from the support of isolation switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses, lightning arresters and other equipment.
As a leader in the field of nuclear energy heating in my country, Shandong Nuclear Power has not only ensured the safe and stable operation of its units, but also created a nuclear energy heating brand "Warm Core No. 1", taking the first step in the comprehensive utilization of nuclear energy. Equipment such as isolating switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses and lightning arresters also play an important role in nuclear energy heating systems to ensure the stable operation of the heating system. These devices play an indispensable role in power transmission and distribution, providing a demonstration sample for clean heating in winter in our country.
In short, equipment such as isolating switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses and arresters play a vital role in the Haiyang Nuclear Power Project. They are an important part of the power system, providing a strong guarantee for the stable transmission and safe use of power. With the further development of Haiyang Nuclear Power Base, these equipment will continue to play an important role and contribute to my country's energy security and green development.
