China has many various types of nuclear reactors and nuclear facilities, particularly China built, and or the nuclear power plant that also will build a greater number, these reactors and nuclear facilities will be equipped with the electrical penetration of containment.For satisfying technical requirement, China State Bureau of Technical Supervision has issued " npp safety shell electrical penetration " (GB13538-92), State Administration for Quality Supervision and Inspection and Quarantine and national standardization management committee have issued " Quality Identification of npp safety shell electrical penetration " (GB/T25837-2010), at present, Chinese Nuclear Power Design Academy and Kodak Electromechanical Control company limited of Shanghai Power Equipment Research Institute have got permission at production safety shell electrical penetration.The electrical penetration that some nuclear power plant of China has also adopted French AUXITROL company to produce.The crucial insulated enclosure technology of above these electrical penetrations all adopts the organic materials such as polyimide, polysulfones, polyetheretherketone, and these organic materials are difficult to satisfy the anti-irradiation of reactor, high temperature resistant, anti-glutinous change, the specific (special) requirements of long-lived phase.Tokyo Electric Power points out to the analysis of Fukushima nuclear leakage event that electrical penetration with the organic material epoxy sealing cannot stand the temperature and pressure under the accident and generating hydrogen leaks.The electrical penetration complex manufacturing of the organic material sealing that China is using, yield rate is low, involves great expense.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of ceramic seal electrode electrical penetration, be a kind of simple and reliable for structure, cost is lower, can satisfy anti-irradiation, the electrical penetration of high temperature, chemical corrosion, airtight, antidetonation, the specific (special) requirements such as fire-resistant, and guarantee that it is no less than 60 year serviceable life at reactor environment, for the operation of reactor long-term safety provides safeguard.
The utility model technical solution problem adopts following technical scheme:
Ceramic seal electrode electrical penetration, comprise cylindrical shell, be axially disposed within many interior bodys of cylindrical shell, be welded on the pressure guiding pipe on the cylindrical shell, tensimeter and the impact tube that links to each other with described pressure guiding pipe, the two ends of described cylindrical shell are welded with seal flange, seal with cutting ferrule between the two ends of described body and the described seal flange, be axially arranged with one or more conductor in the described body, the two ends of body are welded with end plate sealing, between the two ends of described conductor and the described end plate with ceramic seal electrode sealed with brazing.
Design feature of the present utility model also is:
Described internal diameter of tube body forms radial support to being provided with a plurality of ceramic support plates to described conductor.
Described cylinder internal diameter forms radial support to being provided with a plurality of support plates to described body.
Described cylinder internal diameter is to being provided with screen layer, and described screen layer and described cylinder inboard wall and tube wall are tightly connected.
The outer wall of described cylindrical shell is welded with joint flange.
The two ends of many described conductors are connected in parallel in the junction box by extended line.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Because electrical penetration conductor assembly of the present utility model adopts ceramic seal electrode method for welding to realize sealing and the insulation of electric conductor, therefore this electrical penetration has high high temperature resistant, pressure and lower released gas rate, this electrical penetration only uses metal and the stupalith of physics, stable chemical performance, do not use organic material, so the anti-irradiation of this electrical penetration, high temperature, the characteristics of long-lived phase; Mature production technology is reliable in addition, and cost is lower.
