电气贯穿件产品属于核能发电领域,涉及核安全的电气产品。在国内核电大发展的前期立项,当时国内在建和运营的核电站全部采用进口设备,设计和制造技术被国外垄断。立项目的就是打破垄断、填补空白、降低成本,生产拥有自主知识产权的产品。电气贯穿件是固定式核电站中沟通安全壳内外的电气联系,防止放射线泄漏的最后一道屏障的重要的电气设施。电气贯穿件必须在正常或事故条件下,它们都应能承担起由设计规定的功能,其在安装寿命期限内能保持核反应堆安全壳压力边界的密封性、电导线穿过的完
Electrical penetration products belong to the field of nuclear power generation, involving nuclear safety of electrical products. At the early stage of major development of nuclear power in China, all imported nuclear power plants under construction and operation in China were imported and the design and manufacturing technologies were monopolized by foreign countries. The project is to break the monopoly, to fill the gap, reduce costs and produce products with independent intellectual property rights. Electrical penetrations are important electrical installations in the stationary nuclear power plant that communicate the electrical connections inside and outside the containment and prevent the last barrier to radiation leakage. The electrical penetrations must, under normal or accidental conditions, be capable of assuming the function specified by the design and capable of maintaining the tightness of the nuclear reactor containment pressure boundary over the life of the installation.
