Development of Conductor Feedthrough Module of LV Electrical Penetration Assembly for Research Reactors

本文介绍了一种用于各种实验研究堆反应堆厂房内、外电缆连接的新型灌封组件式低压电气贯穿件。该贯穿件采取模块结构,便于拆卸和更换。导体组件自身的孔道密封采用阻燃型环氧树脂灌封实现,与端板孔道之间的密封由“O”型橡胶圈来保证,已通过气密性和电气性能型式试验的验证,满足实验研究堆工程要求。

A LV electrical penetration assembly with perfusion sealing conductor feedthrough module was developed, which can be used for the connection of internal and external cables through the wall of the research reactor workshop. The LV electrical penetration assembly was combined with several independent modules. The maintenance and replacement of the assembly can be easily done in service. The sealing of conductor feedthrough module was achieved with the perfusion of self-extinguishing epoxy. The leakage between the conductor feedthrough module and the end plate module was blocked with rubber rings. The result of the leakage test and the electrical performance test for the samples of conductor feedthrough module satisfied the requirement of research reactor. The structure of the new electrical penetration assembly is simple and compact. It can be manufactured with mature technology and cost low price. The performance of the assembly is steady. It can be used widely in research reactors.
