Description
Technical field
The present invention relates to a kind of electrical penetration of pressure vessel, particularly a kind ofly be applied to occasions such as nuclear power plant and various research containment vessels, and can satisfy the electrical penetration of anti-irradiation, high temperature, pressure-bearing, performance requirement such as airtight.
Background technology
China State Bureau of Technical Supervision has issued " npp safety shell electrical penetration " national standard (GB13538-92).The correlation technique of China in this field mainly contains the electric connector that the band single track electric conductor sealing of the Tsing-Hua University's high temperature gas cooled reactor development of doing is studied by the Ministry of Electronics Industry the 23rd at present, and element two factories of Jiangsu group of Huitong are the 1E level electric connector of Qia Xima reactor development, and China does not also have the development and production of electrical penetration product at present.External existing electrical penetration product, for example the Qinshan nuclear power plant of China has just adopted the electrical penetration that French AUXITROL company produces.In existing external electrical penetration, electric conductor adopts polyimide to insulate, conductor assembly adopts the polysulfones technology such as sealing of swaging to realize the sealing of two pass electric conductor and insulate, conductor assembly adopts bite type to be connected with end plate and seals, and external cable links to each other with the penetration piece conductor assembly by terminal row or the line nose among the junction box.The released gas rate of this electrical penetration is higher relatively, contain organism such as polysulfones in the particularly this electrical penetration, be difficult to satisfy the anti-irradiation of reactor, high temperature resistant, creep resistant, the specific (special) requirements of long-lived phase, and the complex manufacturing of this electrical penetration, yield rate low, involve great expense.
Summary of the invention
Fundamental purpose of the present invention provides a kind of simple and reliable for structure, cost is lower, can satisfy the electrical penetration of anti-irradiation, high temperature, chemical corrosion, airtight, antidetonation, specific (special) requirements such as fire-resistant, and guarantee that it has be no less than the serviceable life in 40 years under reactor environment, for the safe operation of reactor provides safeguard.
The present invention is achieved through the following technical solutions: a kind of containment vessel glass or ceramic post sintering electrical penetration; comprise the protective cover that is arranged in the pre-pipe laying; leak detecting device; the flange that links to each other with pre-pipe laying; cable plug and by conductor assembly; the electrical penetration body that package shell and end plate are formed; it is characterized in that: described conductor assembly contains one or more H shape conductor assemblies; each H shape conductor assembly is made up of the connector seat at one or more electric conductor and two ends thereof, and being connected between described electric conductor and the connector seat adopted glass or ceramic post sintering mode.
H shape conductor assembly of the present invention welds with the employing that is connected between the end plate; But described connector seat is made by the valve material; Cable plug adopts the electric connector plug of band sealing, directly is connected with the connector seat.
The present invention compared with prior art, have the following advantages and the high-lighting effect: because " H " shape conductor assembly adopts glass or ceramic post sintering mode to realize sealing of two pass electric conductor and insulation in the electrical penetration of the present invention, remaining is sealed into welding manner, so this electrical penetration has higher voltage endurance capability, lower released gas rate; Particularly this electrical penetration does not use organic material, therefore has anti-irradiation, high temperature, the characteristics of long-lived phase; Its mature production technology is reliable in addition, and cost is low.

Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Electrical penetration of the present invention comprises penetration piece body, leak detecting device, cable plug 1, protective cover 2 and joint flange 6.The penetration piece body comprises " H " shape conductor assembly 3, package shell 4 and two end plates 5, must design according to pressure container standard joint flange 6 and penetration piece body.Each " H " shape conductor assembly 3 is made up of the connector seat 8 at one or more electric conductor 7 and two ends thereof, adopts glass or ceramic 9 sintering to insulate between electric conductor 7 and the connector seat 8 and seals.But connector seat 8 is preferably made by the valve material, to guarantee having close thermal expansivity between connector seat 8, glass or pottery 9, electric conductor 7 threes, prevents to cause leakage because of temperature variation causes glass or pottery 9 crackings.Each electrical penetration can be arranged several " H " shape conductor assemblies 3 as required." H " shape conductor assembly 3 passes the penetration piece body, and two connector seats 8 weld with two end plates 5 respectively, form the confined space of penetration piece body.Leak detecting device links to each other with end plate 5 by pressure guiding pipe 10, comprises parts such as source of the gas 11, tensimeter 12, valve 13.Leak detecting device on the one hand can the continuous monitoring electrical penetration slip, make-up gas in electrical penetration where necessary on the other hand.Cable plug 1 can directly link to each other with two connector seats 8 of " H " shape conductor assembly 3 for the electric connector plug of band sealing, and the inside and outside electric path that provides of containment vessel structures is provided.Joint flange 6 on the penetration piece body welds mutually with pre-pipe laying 14 on the containment, forms the inside and outside pressure barrier of containment vessel, prevents that the objectionable impurities that reactor produces from escaping.The perforate sealing of entire reaction heap containment is realized by the welded seal between the welded seal between joint flange 6 and the containment vessel built-in fitting and " H " shape conductor assembly 3 and the two end plates 5.Protective cover 2 usefulness screws link to each other with end plate 5, with protection cable plug 1 and attached cable 15, also have dustproof, moistureproof effect in addition.The leakage monitoring function of electrical penetration body is realized by leak detecting device.
The electric conductor insulation and the sealing of two pass electric conductor of electrical penetration are realized by H shape conductor assembly 3, so H shape conductor assembly 3 is cores of this electrical penetration technology.The technical foundation of " H " shape conductor assembly 3 foundations is glass or ceramic post sintering electric connector technology, very mature and reliable, the widespread use in comprising a plurality of fields such as reactor engineering, Aero-Space of this technology." H " shape conductor assembly 3 is to have two connector seats 8 and conductor 7 two ends sintering with the key distinction of electric connector, and glass or ceramic 9 sintering had both played the effect of two pass electric conductor sealing, served as the insulation between electric conductor and the connector seat again." H " shape conductor assembly 3 can require according to the various electrical design of national standard " npp safety shell electrical penetration " regulation to design, can produce high voltage power, low-voltage-powered, low voltage control, instrument, coaxial, three various types of " H " shape conductor assemblies 3 such as coaxial according to the difference of employing electric conductor, satisfy the electrical penetration that the various electrical design of reactor require thereby can produce.
