Replaceable ceramic or glass type sealed electrical penetrating piece assembly

Abstract

The invention discloses a replaceable ceramic or glass type sealed electrical penetrating piece assembly. The penetrating piece assembly comprises a circular-tube-shaped stainless steel assembly shell, an insulated conductor is coaxially arranged in the assembly shell, ceramic sealing pieces are arranged at two ends of the insulated conductor, the outer walls of the ceramic sealed pieces and the inner wall of the end part of the assembly shell are sealed through elastic metal transition rings; a plurality of penetrating piece assemblies are coaxially arranged in a circular-tube-shaped stainless steel penetrating piece body, end plates are arranged at two ends of the circular-tube-shaped stainless steel penetrating piece body, the peripheries of the end plates and the inner wall of the penetrating piece body are sealed through elastic metal sealing rings; and the assembly shell and the end plates arranged at the two ends are sealed through sealing blocks and sealing holes. The penetrating piece assembly can solve the problem of the change of an electrical penetrating piece sealing conductor. Double-way sealing and multi-way sealing structures are realized to adapt to different electrical penetrating requirements.

Description

Technical field: [0001] The invention relates to a replaceable ceramic or glass type sealed electrical penetrating part assembly, which is applied to nuclear power plants and various research reactor containment vessels and the like. Background technique: [0002] With the development of my country's nuclear power industry, the research, production and use of electrical penetrations on containment are also developing continuously. From 1974, Shanghai 728 Design Institute began to develop electrical penetrations for nuclear power plants; then Dalian 523 Factory also conducted trial production of low-voltage power ceramic electrical penetrations. Up to now, two factories in my country, China Nuclear Power Research and Design Institute and Shanghai Power Generation Equipment Design and Research Institute, have begun to produce polysulfone electrical penetrations for nuclear power plants, and have begun to supply the needs of the domestic nuclear power market. These two product...

Problems solved by technology

Therefore, the disadvantage of this structure is that it is not easy to replace the sealed insulated conductor. If the sealed conductor leaks or is damaged during use, the sealed conductor cannot be replaced, and the entire electrical penetration needs to be replaced.

This has brought great inconvenience and loss to the project
