[First Embodiment]
A cable penetration (wiring penetrating device) according to the first embodiment of the present invention will be described.

  FIG. 1 is a longitudinal sectional view of a first cable penetration 10A which is an example of a cable penetration (wiring penetrating device) according to the first embodiment of the present invention.

  A first cable penetration 10A shown in FIG. 1 includes, for example, a sleeve 2 as a nozzle attached to a vessel such as a reactor containment vessel 1, a header ring 3 attached to one end of the sleeve 2, and the header ring. 3, a module unit support 5 which is attached to a support rod 4 and holds and fixes the first cable support module unit 11 </ b> A inside the sleeve 2, and a cable portion 7 of the cable module 6 is attached inside the sleeve 2. The first cable support module unit 11A to be protected and the shell 12 for fixing the first cable support module unit 11A inside the sleeve 2 are configured. Note that reference numeral 8 shown in FIG. 1 is a shielding wall. Although not shown in the present embodiment, the plane (front surface, upper surface, and lower surface) and cross section are configured in substantially the same manner as conventional cable penetration.

  FIG. 2 is a configuration diagram illustrating a configuration example of the first cable support module unit 11A according to the first cable penetration 10A, and FIG. 2A is a front view of the first cable support module unit 11A. FIG. 2B shows the first cable support module unit 11A constituting the first cable support module unit 11A. FIG. 2B shows the first cable penetration 10A as viewed from a direction perpendicular to the axial direction (up and down direction of the paper surface). FIGS. 2 (c) and 2 (d) are front views showing an example of the cable support module 13A, and the first cable support module 13A shown in FIG. 2 (b) is indicated by arrows AA (BB). It is a top view at the time of seeing from a direction (arrow view).

  The first cable support module unit 11A shown in FIG. 2A includes a first cable support module 13A that holds the cable portion 7 of the cable module 6 inside the sleeve 2, a cover 14 that covers the periphery, A centering piece 15 for positioning one cable support module 13A in the circumferential direction in the sleeve 2 is attached.

  The first cable support module 13A shown in FIG. 2B has, for example, a plate-like holding portion 18 that holds the cable portion 7 at two positions on both ends, and is in a reel shape (FIG. 2C described later). The cover 14 that covers the periphery of the support 19A formed in a circular shape in the center of the support 19A is fixed by a fixing means such as a screw 20 or the like. As shown in FIG. 2 (a), the modules are multistaged as necessary, and the modules are connected by connecting means such as bolts 21 and nuts 22, and as necessary, the cover 14 and the centering piece 15 Are attached to complete the first cable support module unit 11A.

  In the first cable support module unit 11A shown in FIG. 2A, for convenience of explanation, a bolt 21 and a nut 22 that connect the first cable support module 13A shown in FIG. (Although it is illustrated as if bolts 21 and nuts 22 are present on the outer diameter side with respect to the cover 14 at first glance), the inner diameter side actually covered with the cover 14 is illustrated. So that the cover 14 is not visible from the outside unless the cover 14 is transparent.

  The first cable support module 13A shown in FIG. 2B is an example, and the structural unit is not limited to that shown in FIG. What is comprised of at least two or more parts can be referred to as a cable support module. For example, a structure formed by connecting two supports 19A with bolts 21 and nuts 22 may be referred to as a first cable support module 13A.

  In this case, the cover 14 can double the axial length of the first cable support module 13A shown in FIG. 2A so that the two supports 19A can be covered together. A configured cover or a cylindrical cover that is formed in an integral structure and can cover the entire circumference may be applied.

  Furthermore, the passage hole 25 of the cable portion 7 provided in at least one support 19A is, for example, as shown in FIG. 2C, so that the number of the cable modules 6 and the number of the passage holes 25 are 1: 1. Alternatively, as shown in FIG. 2D, the passage hole 25 may be a long hole 26, and the number of cable modules 6 and the number of long holes 26 may be a plurality of one-to-one. In the case of the support 19 </ b> A having a plane shown in FIG. 2C, the cable portion 7 of each cable module 6 can have a function of ensuring a predetermined separation distance.

  Furthermore, although the support 19A is formed in a reel shape as an example, the support portions 18 may be configured to be independent from each other, that is, a plurality of disk-like structures. In this case, the cover 14 supports the holding portions 18 in the first cable support module 13A.

  On the other hand, in order to easily adjust the length of the first cable support module 13A in the axial direction, a disk-shaped spacer having the same cross section as that of the support 19A is prepared, and a plurality of such spacers are inserted as appropriate. The support 19A may be connected.

  Next, referring back to FIG. 1, a method for installing the first cable penetration 10A will be described with reference to FIG.

  First, in the first cable penetration 10A shown in FIG. 1, first, the header ring 3 side (the upper side in FIG. 1) is sealed. That is, one end of the sleeve 2 is sealed by welding or the like to the header ring 3 to which the module unit support 5 is attached and the sleeve 2. Thereafter, the first cable support module unit 11A corresponding to the length of the sleeve 2 is loaded. The first cable support module unit 11A is assembled by connecting a plurality of first cable support modules 13 with bolts 21 and nuts 22 in advance, and attaching the cover 14 and the centering piece 15. Then, the shell 12 is attached and fixed in the final stage, and the shell 12 and the sleeve 2 are sealed on the shell 12 side (the lower side in FIG. 1) by welding or the like.

  Here, when the length in the axial direction does not match during on-site work, conventionally, the cover of the integrated cable support module unit is removed, and then the position of the support, support rod and cover The workability is not good because work such as adjustment of the length is required, whereas in the first cable penetration 10A, the first cable support module 13A is connected to be added one step or disassembled to be deleted one step or The axial length of the first cable support module unit 11A can be relatively easily adjusted by adjusting a spacer to be inserted into the connecting surface between the first cable support module 13A and the first cable support module 13A. Can be adjusted.

  Note that the direction in which the first cable support module unit 11A is loaded can be changed from the reverse side. The installation method in this case is substantially the same as that described above. However, in this case, the shell 12 and the holding portion 18 of the support 19A that is the end of the first cable support module unit 11A are connected, and the shell 12 and the sleeve 2 are sealed by welding or the like. Then, the header ring 3 with the module unit support 5 attached is attached and fixed at the final stage.

  According to the first cable penetration 10A and its installation method, the cable support module unit 11A is modularized, and a compact cable that enables installation or adjustment work in smaller units that could not be realized by conventional cable penetration. Since the support module 13A is provided, the work area can be reduced (narrowed) compared to the conventional case. Further, even when the axial length adjustment occurs, the adjustment can be performed more easily than in the past.
