| 摘要 |
The invention relates to an electrical penetration assembly (100) for a nuclear reactor vessel, that can be mounted in an aperture (20) of a nuclear reactor vessel (10), said electrical penetration assembly (100) being characterised in that it comprises: a penetration body (105) comprising: a first end (110) suitable for being positioned inside the vessel; a second end (120) suitable for being positioned outside the vessel; a sealed electrical connector (130) providing a first seal for the electrical penetration assembly (100), said sealed electrical connector (130) insulating the penetration body (105) at the first end (110); a feed-through carrier flange (140) having a plurality of unitary electrical feed-throughs (123), each unitary electrical feed-through (123) allowing a single electrical conductor (160) to pass therethrough, thereby ensuring the continuity of the electrical connections, each unitary electrical feed-through (123) being individually insulated by an individual insulator (142) providing a second seal, the unitary electrical feed-throughs (123) insulating the penetration body (105) at the second end (120); and an anti-ejection device formed by the engagement between a narrowed portion (141) provided at each unitary electrical feed-through (123) and a shoulder (151) that is larger in size than the narrowed portion (141) of each unitary electrical feed-through (123) and provided on each of the electrical conductors (160) of said unitary feed-throughs (123). |
