Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings. In the specification, the same or similar reference numerals denote the same or similar components.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.
FIG. 1 shows a schematic diagram of an electrical penetration for a pressure vessel according to one embodiment of the present invention. As shown in fig. 1, the electrical penetration includes: conductor assembly 1, comprising: a conductor 10; the sheath body 20 is sleeved outside the conductor 10, a gap 21 is formed between the sheath body 20 and the conductor 10, and the sheath body 20 provides insulation protection for the conductor 10; a sealing part 30 connected with the conductor 10 and the sheath body 20 and enclosing a cavity 31 together to seal the end of the gap 21; wherein the sheath 20 is configured to be mounted to an opening of a shell of a pressure vessel; or the electric penetration piece also comprises a mounting part 2, the mounting part 2 is provided with a through hole 51, the conductor component 1 penetrates into the through hole 51, and the sleeve body 20 is mounted at the through hole 51.
In the electric penetration piece for the pressure vessel according to the embodiment of the invention, the gap 21 is formed between the conductor 10 and the sheath body 20, so that the gap 21 can absorb the expansion of the conductor 10 and the sheath body 20 under the high-temperature condition, the generation of excessive thermal stress is avoided, and the electric penetration piece is ensured to be suitable for the high-temperature environment. In addition, the end part of the gap 21 is sealed by the cavity 31 enclosed by the sealing part 30, the conductor 10 and the sleeve body 20, which is beneficial to ensuring the good sealing performance of the electrical penetration piece and avoiding the influence of the existence of the gap 21 on the sealing performance.
The conductor 10 of the electrical penetration assembly needs to be mounted to other components, and in order to avoid the conductor 10 from being in direct contact with other components at the mounting position to be electrically conducted, a structure having an insulating property needs to be provided at least at the mounting position of the conductor 10 to provide insulation protection, and such a structure may be, for example, a sheath 20. However, if the sheath 20 is tightly connected to the conductor 10, when the electrical penetration assembly is applied to a high temperature environment, the expansion of the conductor 10 and the sheath 20 may cause a large thermal stress between the two, causing damage to the electrical penetration assembly or posing a safety threat. The present invention solves this problem by providing a gap 21 between the jacket 20 and the conductor 10.
The jacket body 20 may be mounted in any suitable manner to fit over the conductor 10 with a gap between the conductor 10. For example, the conductor 10 is provided with a first projection and a second projection between which the sheath 20 abuts. Alternatively, the jacket body 20 is mounted by being connected to the conductor 10 by a connection structure, which may be, for example, the seal 30, i.e., the jacket body 20 may be connected to the conductor 10 by the seal 30.
The provision of the gap 21 may cause a problem in terms of sealability. When the electrical penetration is mounted to the pressure vessel, the gap 21 may communicate the internal and external environment of the pressure vessel, which is undesirable. The invention solves the technical problem by arranging the sealing part 30, and realizes the internal sealing of the pressure container by isolating the internal and external environments of the pressure container by the sealing part 30. The seal portion 30, together with the conductor 10 and the covering 20, encloses a cavity 31, and an end of the gap 21 communicates with the cavity 31 but cannot communicate with a space outside the cavity 31. Thus, when the electrical penetration is mounted to the pressure vessel, the cavity 31 may prevent the gap 21 from communicating the internal and external environments of the pressure vessel.
The sealing portion 30 may be a cylindrical structure, and is disposed outside the conductor 10, and has one end connected to the conductor 10 and the other end connected to the sheath 20. In order to ensure a good sealing of the cavity 31 against the end of the gap 21, a tight connection between the seal 30 and the conductor 10 and the jacket body 20 is obtained. In the embodiment of the present invention, the sealing portion 30 is welded to the conductor 10 and the sheath body 20, so that the sealing performance of the joint can be achieved in a simple manner, and the cavity 31 can be ensured to perform good sealing on the end of the gap 21. Of course, in other embodiments, the sealing property of the joint between the sealing portion 30 and the conductor 10 and the sheath body 20 may be achieved by a sealing member.
In some embodiments, the sealing portion 30 includes a corrugated sleeve or a tapered sleeve, so as to absorb deformation of the conductor 10 at high temperature, and prevent large thermal stress from being generated at the connection of the conductor 10 and the sealing portion 30. The surface of the corrugated sleeve is in a wave shape. The tapered sleeve is trapezoidal in cross section, and the radial dimension of the first end of the tapered sleeve is smaller than the radial dimension of the second end. The seal 30 may comprise a plurality of interconnected sleeves.
In some embodiments, the electrical penetration may not include the mounting portion 2, and the jacket 20 is configured to be mounted to an opening of a casing of a pressure vessel such that one end of the conductor 10 is located inside the casing and the other end is located outside the casing. The jacket body 20 may be configured to be welded to an opening of a shell of the pressure vessel; alternatively, the jacket body 20 may have a flange, and the flange (e.g., a flange) may be mounted to the opening periphery of the casing of the pressure vessel by a fastener (e.g., a bolt), and may be sealed at the connection of the flange and the casing by a sealing member (e.g., a gasket). Such an embodiment is suitable for use in situations where only a small number of conductor assemblies 1 need to be provided at the opening of the housing of the pressure vessel.
In other embodiments, a plurality of conductor assemblies 1 may need to be disposed at the opening of the casing of the pressure vessel, and the electrical penetration assembly further includes a mounting portion 2, wherein the plurality of conductor assemblies 1 are mounted on the mounting portion 2, and then the mounting portion 2 is mounted at the opening of the casing of the pressure vessel. The mounting portion 2 is formed with a plurality of through holes 51, a plurality of conductor assemblies 1 are inserted into the plurality of through holes 51, and the covering 20 is mounted to the through holes 51. In the embodiment of the present invention, the sheath body 20 is welded to the through hole 51, which ensures both the secure attachment of the sheath body 20 to the mounting portion 2 and the sealing of the attachment, and the sealing is simple. Of course, in other embodiments, other connection means and other sealing means at the connection may be used. The number of conductor assemblies 1 to which the mounting part 2 is mounted can be determined in combination with the actual requirements and the dimensions of the mounting part 2.
In some embodiments, the mounting portion 2 is configured to be welded to an opening of a shell of a pressure vessel. In other embodiments, the mounting portion 2 has a flange that is mounted to the periphery of an opening in the casing of the pressure vessel by fasteners, and a seal may be provided to provide sealing at the mounting. The flange may be a flange.
The mounting part 2 may include a cylinder 52 and an end plate 54, wherein the end plate 54 is provided at one end of the cylinder 52, the other end of the cylinder 52 is open, and a through hole 51 is formed in the end plate 54. The cylinder 52 and the end plate 54 may be welded as one body. The cylinder 52 may be threaded into an opening in the shell of the pressure vessel and welded thereto. A flange may be provided on the barrel 52 or end plate 54 for connection to a flange at an opening in the reactor pressure vessel. The barrel 52 and end plate 54 may be made of a nuclear grade stainless steel material to provide good heat dissipation.

The parts to be welded to the jacket body 20 are often made of a metal material. The sheath 20 needs to have at least an insulating material for insulation.

The two connecting portions 34 are welded to the two ends of the insulating portion 32 to form an integral cylindrical structure.
