Description

  The present invention relates to a distribution board having two or more incoming lines in a cabinet.

  In the distribution board 31 having a plurality of incoming lines, the electric device 32 and the conductive bar 33 are arranged separately for each system. For example, as shown in FIG. As shown in FIG. 4, a method of arranging the upper and lower parts separately has been adopted.

As shown in FIG. 5, when connecting to each bus 34 group without dividing a plurality of incoming lines, the bus 34 group is arranged in two stages, the front side and the bottom side, and is configured by the bus 34 and the like. The charging part was fixed to the support base.

  However, in the distribution board 31, since the conductive bars 33 are arranged side by side, the distribution board 31 needs to have a wide width, the cabinet constituting the distribution board 31 becomes large, and the installation location is also restricted. At the same time, there was a drawback that the price would rise. Further, since the charging unit is fixed to the support base 35, modification such as addition of a branch requires a complicated work of removing all the charging units, and thus cannot be easily performed.

  Therefore, the present invention aims to reduce the cabinet size of a distribution board with a plurality of incoming lines, and its structure is such that fixed rails are arranged at both ends of the cabinet, the rails are passed to the fixed rails, and the rails are Attach the slide rail, fix the equipment mounting rail to the end of the slide rail, attach the branch panel to the equipment mounting rail or fixed rail, and place and fix the electrical equipment on the branch panel to configure the distribution board. When the electrical panel is composed of multiple systems, the branch panel is attached to the equipment mounting rail or fixed rail for each system, and the electrical equipment attached to the equipment mounting rail can be moved by sliding operation, and the mounting position can be changed as necessary. It is possible to do.

  Also, the busbars are stacked by system, and the branch breaker arranged on the distribution board can be connected to a bus group of another system by inverting the branch bar that connects the branch breaker and the busbar. .

  In the distribution board according to the present invention, according to the present invention, fixed rails are arranged at both ends of the cabinet, the rails are passed to the fixed rails, the slide rails are attached to the rails, and the equipment mounting rails are attached to the ends of the slide rails. If a distribution panel is constructed by attaching a branch panel to the equipment mounting rail or fixed rail, and mounting and fixing electrical equipment on the branch panel, and the distribution board is composed of multiple systems, branch by system Since the panel is attached to the equipment mounting rail or fixed rail, the electrical equipment attached to the equipment mounting rail can be moved by sliding movement and the mounting position can be changed as necessary. Makes it easy to perform construction, inspection, modification, etc.

  In addition, the busbars are stacked for each system, and the branch breakers placed on the distribution board can be connected to a group of busbars in another system by inverting the branch bar that connects the branch breaker and busbar. Thus, there is no need to arrange electrical equipment, space saving and assembly work is easy.

  With the goal of providing a distribution board that can store electrical equipment in a space-saving manner, construction, inspection, and modification can be performed easily with the minimum number of parts.

  An embodiment of a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The distribution board 1 is configured by arranging electrical devices such as a branch breaker 2 in a cabinet 3. Fixed rails 4 are arranged at both ends of the cabinet 3. The rail 5 is passed and fixed to the fixed rail 4. A slide rail 6 is attached to the surface of the rail 5 so as to be movable by a sliding operation. A long hole 7 is formed in the slide rail 6, and a position to be fixed to the rail 5 within the range of the long hole 7 can be changed. The device mounting rail 8 is fixed to the end of the slide rail 6.

  The branch breaker 2 is mounted and fixed on the branch panel 9, and a fixing hole 10 is provided so that the branch panel 9 can be fixed to both the fixed rail 4 and the device mounting rail 8. Depending on the system, the branch panel 9 is attached to the fixed rail 4 or to the equipment mounting rail 8. For example, the first system branch breaker 2 a is fixed to the device mounting rail 8, and the second system branch breaker 2 b is fixed to the fixed rail 4. Further, branch breakers 2 of the same system are connected to the same group of buses 11 via branch bars 12. The bus 11 group has two upper and lower stages. For example, the first system branch breaker 2a is connected to the lower first bus group 11a in FIG. 1, and the second system branch breaker 2b is connected to the upper branch circuit 2b in FIG. Connect to the two bus group 11b.

  Normally, when the electrical equipment is stored in the cabinet 3 of the distribution board 1, the bus bar 11 can be stored in a minimum space when arranged in a vertically stacked state. However, as shown in FIG. 1, when the bus bars 11 are stacked for each system, the connection screw 13 of the branch bar 12 connected to the lower bus bar group 11b cannot be visually observed. In that state, work such as construction, expansion, and inspection cannot be performed. During the work, the branch breaker 2a of the first system attached to the equipment mounting rail 8 is slid by the slide rail 6, the upper and lower busbars 11 are shifted, and the lower busbar group 11b is also visible from the front. Move.

  At the time of storage, the bus bars 11 are overlapped to form a small space, but at the time of work, the position of the bus bars 11 can be moved so that the work can be performed.

  The connecting portion between the bus bar 11 and the branch bar 12 is formed in a plane, and the height of the terminal portion of the branch breaker 2 and the bus bar 11 is adjusted by bending the branch bar 12. The bending step of the branch bar 12 can connect the branch bar 12 to the first bus group 11a and, when inverted, connect to the second bus group 11b.

  Conventionally, the branch breaker 2 is arranged for each system. However, since the branch bar 12 can be reversed to connect to the bus group 11 of another system, the branch breaker 2 is continuously arranged regardless of the system. Can save space. In addition, when adding circuits, the branch breaker 2 can be arranged regardless of the system, saving space.

  Further, when the existing branch breaker 2 is to be connected to another system, the rail for mounting the branch panel 9 is changed from the fixed rail 4 to the equipment mounting rail 8 or from the equipment mounting rail 8 to the fixed rail 4. This is possible by inverting 12.

  The branch panel 9 on which the branch breaker 2 is placed and fixed can be moved to a fixed position by being fixed to the slide rail 6. In a normal use state, the branch panel 9 is compactly stored in the cabinet 3 for construction, expansion, inspection, etc. In this work, the distribution panel can be moved together to create a work space, providing a distribution board that is easy to work with while saving space.
