Description

  The present invention relates to a distribution board in which electric devices such as a main breaker and a branch breaker are arranged on a base, and the electric devices are connected by a conductor such as an electric wire or a conductive bar.

Conventionally, when a high-function device 34 is mounted on a distribution board 33 configured by arranging a main breaker 31, a branch breaker 32, etc., the branch breaker 32 is considerably removed, and an additional device 34 is attached to that portion. . For example, when attaching an additional device to a distribution board in which ten branch circuits can be wired, a space necessary for attaching the additional device is secured by replacing the branch circuit breaker. For this reason, if the additional device needs space for two circuit branch breakers, only eight circuit branch breakers can be arranged. Or it was changed to a larger base.

  When installing additional equipment by replacing the branch breaker with the conventional distribution board, if the number of branch breakers that can be arranged is reduced or cannot be reduced, the cabinet must be enlarged and the manufacturing cost is reduced. There was a drawback of being raised.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a distribution board in which an additional device can be attached with a simple structure without reducing the number of branch circuits, and the structure is such that a conductive bar is connected to a main breaker. And a branch bar connected to the main bar, the connection position of the main bar to the branch bar is the lower end of the branch bar on the main breaker side, and the connection position of the feed terminal to the branch bar is the branch breaker A position that is continuous with the arrangement and is provided at the top of the branch bar, and is connected to the upper part of the main breaker side end of the branch bar that is the upper part of the connection position between the main bar and the branch bar, and the branch bar of the feed terminal An additional device mounting space is secured at the lower part of the housing.

Distribution board according to the present invention, the connection position of the main trunk bar distribution bar and main breaker-side end part of the distribution bar, also, a position continuous to the sequence of branch breakers the connection position of the distribution bar of the feed terminal In addition, because it is provided on the upper part of the branch bar, additional equipment mounting space is secured at the upper part of the main bar connection part connected from the main breaker to the branch breaker and the lower part of the connecting position of the feed terminal branch bar. The distribution board can be configured without reducing the number of branch circuits and without causing inconvenience to other wirings. In addition, it is possible to attach a high-functional device without increasing the size of the cabinet, and it can be provided at a lower cost compared to increasing the size of the cabinet.

  The purpose of providing a distribution board to which high-functional equipment can be attached was realized without changing the size of the cabinet and without reducing the number of branch circuits.

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

  Electric equipment such as a main breaker 2 and a branch breaker 3 is arranged on the base 1 to constitute a distribution board 4. Electrical devices such as the main breaker 2 and the branch breaker 3 are connected by conductors such as electric wires and conductive bars 5.

  The branch breaker 3 may be a plug-in type that can be connected simply by being inserted into the conductive bar 5. A main bar 5a is connected to the terminal portion 2a of the main breaker 2, and a branch bar 5b is further connected to an end of the main bar 5a. In order to effectively use the limited space of the base 1 for the arrangement of the electrical equipment and the conductive bar 5, the branch breaker 3 is arranged in the upper and lower stages in the remaining portion where the main breaker 2 is arranged. Between the upper stage and the lower stage, the branch bars 5b are stacked in the number of phases. The main bar 5a connects the branch bar 5b and the main breaker 2.

  Conventionally, the branch bar 5b is installed with the length L1 of the width in which the branch breakers 3 are arranged. In the present invention, the branch bar 5b has a side end of the branch breaker 3 installed on the main breaker 2 side. A length L2 is extended from the section toward the main breaker. The main bar 5a is connected to the branch bar 5a from the side of the branch bar 5b and fixed with screws 6.

  Conventionally, the upper part S1 of the connecting portion of the main bar 5a, which is a dead space for screwing the main bar 5a to the branch bar 5b, is effective by changing the position of the screw 6. Can now be used. Since the branch bar 5b is also installed, it is possible to secure a space for installing a high-performance device separately from the branch circuit. In addition, branch breakers for branch circuits can be added instead of high-function devices.

  A feed terminal is connected to the end of the branch breaker 3 opposite to the main breaker 2. Conventionally, as with the connection of the main breaker 2, the branch bar 5b is installed with the length L1 of the width in which the branch breakers 3 are arranged, and the feed terminal is fixed to the end by screwing or the like. The length L3 is extended to the branch bar 5b toward the side opposite to the main breaker 2. The branch bar 5b is inserted and fixed from the side.

  Conventionally, the screw S for connecting to the branch bar 5b of the feed circuit has been changed so that the lower part S2 of the connection portion of the feed terminal, which has been a dead space, has been changed in position so that it can be effectively used. became. Since the branch bar 5b is also installed, a space for attaching an additional device can be secured separately from the branch circuit. In addition to the additional equipment, it is possible to add a branch breaker 3 for the branch circuit.

  The connection between the main breaker and the feed terminal to the branch bar is fixed by inserting it from the side of the branch bar with screws, etc., and it has conventionally been a dead space as a screw space for fixing. It is now possible to use the terminal area, and it can be applied to space-saving and multi-circuit distribution boards.

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