Problems solved by technology

The gas leakage rate of this kind of electrical penetration is relatively high, especially this kind of electrical penetration contains organic substances such as polysulfone, which is difficult to meet the special requirements of the reactor for radiation resistance, high temperature resistance, creep resistance, and long life. The production process of electrical penetration parts is complicated, the yield rate is low, and the cost is expensive

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] The electrical penetration of the present invention includes a penetration body, a leak detection device, a cable plug 1 , a protective cover 2 and a connecting flange 6 . The body of the penetration includes an "H"-shaped conductor assembly 3, an assembly housing 4 and two end plates 5, and the connecting flange 6 and the body of the penetration must be designed according to the pressure vessel standard. Each "H"-shaped conductor assembly 3 is composed of one or more electrical conductors 7 and connector sockets 8 at both ends, and the electrical conductors 7 and connector sockets 8 are sintered with glass or ceramics 9 for insulation and sealing. The connector holder 8 is preferably made of a valveable material to ensure that the connector holder 8, the glass or ceramics 9, and the electrical conductor 7 have similar thermal expansion coefficients to...

Abstract

The penetration piece comprises the protection cover buried in the tube, the leak detection set, the connecting flange, the cable plug, the conductor assembly and the body of the penetration piece etc. The conductor assembly contains one or more H type conductor unit. Each H type conductor unit comprises the one or more electrical conductor and the connector socket. The agglomeration of glass or pottery and porcelain is used to connect the conductor with the socket. Since the dual seal and insulation of the agglomeration or the solder method are accepted as well as no organic material is used in the penetration piece, the invention possesses the features of higher withstanding voltage, low gas leakage rate, high temperature and radiation resistant.

Description

technical field [0001] The invention relates to an electrical penetrating piece of a pressure vessel, in particular to an electrical penetrating piece used in nuclear power plants and various research reactor containments, which can meet performance requirements such as radiation resistance, high temperature, pressure bearing, and airtightness. through pieces. Background technique [0002] my country's State Bureau of Technical Supervision has issued the national standard (GB13538-92) of "Nuclear Power Plant Containment Shell Electrical Penetrations". At present, my country's related technologies in this field mainly include the electrical connector with single-channel electrical conductor seal developed by the 23rd Research Institute of the Ministry of Electronics Industry for the high-temperature gas-cooled reactor of Tsinghua University, and the second component factory of Jiangsu Huitong Group for the Qiaxima reactor. Developed 1E-level electrical connectors, and current...
