Abstract

<P>PROBLEM TO BE SOLVED: To provide a compact distribution board satisfying standard values with a simple structure. <P>SOLUTION: The distribution board 1 is formed compactly while satisfying standard values of wiring dimensions without altering the dimensions of a breaker 3 by providing an apparatus mount 6 for securing an electric apparatus on the bottom face of a base 5, forming the apparatus fixing face 6a of the apparatus mount 6 with inclination, and fixing the breaker 3 while inclining against the bottom face of the base 5. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to arrangement of electric devices in a distribution board in which electric devices such as a main breaker and a branch breaker are arranged on a base of a cabinet, and the electric devices are connected by conductive bars.

The distribution board 31 is configured by arranging electrical devices such as a breaker 33 in a cabinet 32. The breaker 33 is arranged in parallel with the bottom surface of the cabinet 32. The cabinet 32 of the distribution board 31 is selected on the basis of the dimension of the equipment to be accommodated and the dimension B including the wiring space for connecting the equipment. The wiring space should have the dimensions determined by the standards.

  However, when the breaker 31 is arranged in parallel with the bottom surface of the cabinet 32 and the cabinet 32 is selected so as to satisfy the dimensions defined in the standard, there is a limit on the dimensions for accommodating the distribution board 33 in a compact manner. Since the cabinet 32 does not become smaller than a certain size, the place where the distribution board 33 is attached is limited.

  Therefore, the present invention aims to provide a compact distribution board that satisfies the standard value with a simple structure, and the structure is provided with a device mounting base for fixing an electrical device on the back of the base, The device mounting surface of the device mounting base is formed with an inclination, and the breaker is attached with an inclination to the back surface of the base.

  The distribution board according to the present invention is provided with a device mounting base for fixing an electrical device on the bottom surface of the base, and the device mounting surface of the device mounting base is formed with an inclination, with respect to the bottom surface of the base Because the breaker is installed at an angle, space can be saved in the cabinet that makes up the distribution board, so the cabinet size can be reduced, and installation is possible even in locations where conventional space is small and cannot be installed. Since it may be possible, there are fewer restrictions on the mounting location.

  The purpose of storing the internal equipment of the distribution board in a space-saving manner and reducing the dimensions of the cabinet was realized while securing wiring space with a simple structure.

  An embodiment of a distribution board according to the present invention will be described with reference to the attached drawing of FIG.

  A distribution board 1 according to the present invention is configured by housing electrical devices such as a main breaker and a branch breaker 3 in a cabinet 2. The branch breaker 3 is connected from both sides to the charging part constituted by the conductive bar 4 and the like. The size of the cabinet 2 is selected in accordance with the wiring dimensions defined in the standard in order to wire electrical equipment.

  An equipment mounting base 6 for fixing the branch breaker 3 is provided on the bottom surface of the base 5 of the cabinet 2. The device mounting surface 6a on the upper surface of the device mounting base 6 is formed with an inclination. The branch breaker 3 is placed on the device mounting surface 6a, and the branch breaker 3 is inclined and fixed with respect to the bottom surface 2a of the cabinet 2. Along with this, the conductive bar 4 connecting the branch breakers 3 is also bent at an obtuse angle so as to face the fixed angle of the branch breaker 3 instead of being bent at a right angle in the vicinity of the terminal portion 3a of the branch breaker 3. To sing. The fixing device for the branch breaker 3 is also inclined according to the fixing angle.

  By tilting and fixing the branch breaker 3, the position of the terminal portion 3b outside the branch breaker 3 is close to the center of the distribution board, so that a space A satisfying the wiring dimensions defined in the standard can be secured. The area occupied by the electrical equipment on the distribution board 1 is reduced, and the overall size of the distribution board 1 is reduced.

  In FIG. 1, the angle of inclination of the branch breaker is substantially V-shaped with the conductive bar at the center when viewed from the side. However, the arrangement of the electrical equipment according to the present invention is not limited to this angle. The branch breakers arranged in parallel may be inclined in the same direction in parallel, or only one row of branch breakers may be inclined and arranged on the distribution board of the present invention. Changes can be made as appropriate without departing from the spirit of reducing the area.

  By fixing the branch breaker placed on the distribution board with an inclination and reducing the area occupied by the electrical equipment on the distribution board, the size of the cabinet of the distribution board is also reduced, and the distribution board installation area It can also be applied when there is a restriction on.

It is explanatory drawing which shows the Example of the distribution board which concerns on this invention. Example 1 It is explanatory drawing which shows the conventional distribution board.
