照）。It is necessary to penetrate the electric conductor into the containment vessel of the reactor for the purpose of measuring, controlling, and supplying power to the reactor, etc. In order to prevent leakage, it is required to penetrate through the partition wall in an airtight manner. In general, this kind of electric conductor penetrating device is composed of a cylindrical housing with a metal flange to be welded through a penetration sleeve attached to the partition wall in a gas-tight manner by welding or the like, and the electric conductor is formed by this cylindrical member. The housing is hermetically pierced and mounted by spaced sealing means so as to form an airtight chamber in the middle of the housing. Epoxy resin is used as one prior art sealing means (see Japanese Patent Application Laid-Open No. 50-100489), and another prior art sealing means is a method of connecting between a cylindrical housing and an electric conductor penetrating the cylindrical housing. And a compound such as rubber or epoxy resin filled in a cylindrical housing so as to embed the sealing material therein (Japanese Patent Publication No. 53-7031 and Japanese Utility Model Publication No. 53-7437).

が長くなり、更に貫通導体の本数を増加することが困難
なため多心化することができない欠点があった。However, the sealing means made of an epoxy resin sealing material has a possibility that airtightness may be broken due to aged deterioration due to a difference between a thermal expansion coefficient of an electric conductor and a thermal expansion coefficient of an epoxy resin. In addition, since the sealing means including a ceramic or glass sealing material and a compound in which the sealing material is embedded must connect conductors on both sides of the sealing material, it is necessary to connect through conductors in an airtight chamber. The airtight chamber becomes long, and it is difficult to increase the number of through conductors.

を特徴とする電気導体貫通装置を提供するものである。The present invention, in order to solve the above-mentioned problem, comprises two cylindrical housings which are hermetically joined to each other, and a conductor penetrating pipe hermetically sealed to each housing and through which a conductor passes. The tubular housing extends through the conductor penetrating pipe inside the two housings in a sealed manner and extends parallel to the conductor from the hermetic chamber between the two hermetic seal portions and opens to the outside to seal the airtightness of the hermetic chamber. An object of the present invention is to provide an electric conductor penetrating device having an airtight detection hole for detection.

きる。With such a configuration, the conductor to be penetrated does not require a connection portion of the conductor in the hermetic chamber, so that the hermetic chamber is not lengthened, and the hermetic seal does not directly penetrate the conductor but a conductor penetrating pipe through which this conductor penetrates. Conducting on the housing, the conductor is hermetic seal, for example, processing of the conductor because it does not receive heat history during glass welding,
The surface treatment can be easily performed, and each hermetic seal portion is separately formed in two cylindrical housings, so that these cylindrical housings are merely air-tightly joined to each other to easily form an airtight chamber therebetween. Can be formed.

により熱伸縮を吸収することができる実益がある。According to the present invention, as described above, since the conductor to be penetrated does not require a connection portion of the conductor in the hermetic chamber, the hermetic chamber does not need to be long, so that the entirety can be formed short.
Also, the hermetic seal does not seal the conductor directly to the housing but seals the conductor penetrating pipe through which the conductor penetrates to the housing, so that the conductor does not receive the heat history at the time of hermetic sealing, and furthermore, each hermetic seal portion Are formed separately in the two cylindrical housings, so that the airtight chamber can be easily formed only by joining these cylindrical housings to each other in an airtight manner. Furthermore, since the airtightness detection hole as the airtightness detection means extends in the housing in parallel with the conductor, the housing can be formed compact without increasing the diameter of the housing. By providing an offset, there is a benefit that thermal expansion and contraction can be absorbed.
