Provided is an electrical distribution method for outputting each bus bus for grounding commonly used for supplying power of different voltages.

In addition, the present invention is formed to have a predetermined width, length and thickness, and a plurality of mounting holes are separately installed in the busway body to fix the bus bar for supplying at least one or more single-phase and three-phase power each having a different voltage, the different Ground busbars of each busbar used for single-phase and three-phase power supply of voltage provide a busway consisting of only one configuration for output in common use.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

2 to 5, the busway of the present invention includes at least one single phase (N, u, v) having different voltages on one busway body 100 which is fixed to the ceiling or the like as the supporting rod 110. And a plurality of U-shaped bus bars 130 are installed to supply power of three phases (R, S, T, and N), and the bus bars 130 are formed in the same shape as the bus bars when extended as a predetermined length. It is connected to each other by a separate connecting bar (130a) having a shape that is pressed into the inside of the bar (130).

In addition, the busway body 100 is formed with mounting holes 180 to which the bus bars 130 are opened so that the bus bars 130 may be mounted, respectively, and the mounting holes 180 may have respective guide rails protruding upward. It is formed by the 190, the separation of the bus bar 130, which is press-fitted by the locking step 120 formed on the guide rail 190 is installed to prevent.

In addition, the guide rail 190 is made of a different color to distinguish each voltage difference in each phase and the same phase.

In addition, a plurality of notches 160 are integrally formed in the mounting hole 180 formed at one side of the busway body 100 so as to separate busways corresponding to respective power sources.

Subsequently, the N-phase busbars 130 commonly used for different voltages in the same phase of the single phase and the three phases have distances on both sides of the guide rail 190 into which the busbars 130 are inserted, i.e., 380V in three phases and 220V in three phases. The distance between terminals is a ≠ b, and in the case of single phase, the distance is 220V and 110V terminal distance c ≠ d.

In addition, the grounding pin 140 is connected to the N-shaped bus bar 130 to ground the casing 170 of the metal material supporting the busway body 100.

And, the busway body 100 is equipped with an upper casing 150 to cover the upper portion, the upper casing 150 by each color (three phase 380V is A color, three phase 220 is B color, single phase 220V (C color, single-phase 110V, D color, etc.) is a socket 400 is located in a predetermined matrix, the through hole 400a corresponding to each mounting hole is formed in the socket 180, respectively.

In addition, a connector 200 having a connection hole 230 corresponding thereto is connected to the socket 180 while the plurality of terminals 210 protrude one-to-one in each phase, and the connector 200 is connected to the socket 200. An outlet 300 for finally supplying power to the device is connected, and a cable 330 and a terminal 310 are respectively installed in the outlet 300.

In addition, the socket 400 has a configuration in which the outlet 300a having a plurality of terminals 310a corresponding to the through hole 400a is directly connected to the electronic device without the need for a separate connector 200. Is done.

The operation of the present invention having the above configuration will be described.

As shown in FIGS. 2 to 5, a plurality of bus bars 130 are inserted into the mounting holes 180 formed on the busway body 100 and separated through the respective guide rails 190, thereby providing voltage. One or more single phase (N, u, v) different from each other and one or more three phase (R, S, T, N) power different from each other are supplied.

At this time, the N phase of the bus bars used in the three-phase and single phase are each used in common so that a power supply having a plurality of polarities with a minimum width can be provided.

In addition, the bus bar 130 has a U-shape to elastically support the terminal inserted therein to prevent a supply failure of power, and each bus bar 130 has a connection bar 130a having the same shape. Through this can be installed to extend to a predetermined length.

In addition, a plurality of notches 160 are formed in the busway body 100 so that the user needs to separate the necessary parts in one installation area, that is, one three phase or two three phases and one single phase as necessary. By being able to use it, one busway can be used as a busway with various phases and voltages.

Subsequently, the grounding bus bars 130 respectively installed on the busway body 100 ground the casing 170 of the metal material surrounding the busway body 100 through the grounding pin 140 to ground the casing. Even if the user touches 170, the user is prevented from being electrocuted.

 In addition, one side of each guide rail 190 has a locking jaw 120 is formed to form a support of the casing 170 when the busway body is separated by the notch 160.

Subsequently, the N-phase busbars 130 commonly used when supplying different voltages in the single and three phases have a distance between both sides of the guide rail into which the busbars 130 are inserted, i.e., 380V and 220V in three phases. Is a ≠ b, and in case of single phase, it is installed so that the terminal distance of 220V and 110V is supplied to c ≠ d, which completely prevents the insertion of three-phase 380V power supply into three-phase 220V. Prevent it.
Where a = terminal distance between guide rails supplied with three phases of 380V, b = terminal distance between guide rails supplied with three phases of 220V, c = terminal distance between guide rails supplied with 220V of single phases, d = single phase This is the terminal distance between the guide rails where 110V is supplied.

In addition, the upper casing 150 installed to cover the upper portion of the busway body 100 has respective colors (three phase 380V is A color, three phase 220 is B color, single phase 220V is C color, single phase 110V is C color). Etc.), the socket 400 is positioned in a predetermined matrix so that the user can be surely connected after confirming the power of 380V and 220V, thereby preventing damage to the device due to the connection of different voltages.
Here, A, B, and C may be defined as different colors, for example, A = red, B = yellow, C = blue, and the like, where A, B, and C need to be defined. However, it is desirable if the color is standardized for convenience of use.

In addition, the guide rail 190 is made of a different color to distinguish each voltage difference in each phase and the same phase to prevent damage by the supply of different voltages by connecting the outlet of the electronic device according to each color .

As described above, the present invention, when using the difference in the distance between the terminals and the configuration of the sockets of different colors and colors, such as each phase and each voltage is applied at the same time triple safety devices are applied to the terminal of the outlet is incorrectly connected It results in a more elevated effect that completely prevents this.

On the other hand, the power distribution method of the present invention will be described.

In the power distribution method of the present invention, as shown in Figs. 4 and 5a, b, bus bars 130 corresponding to each power supply are separately installed so that single-phase and three-phase powers of different voltages are simultaneously supplied to one busway. do.

At this time, each of the ground bus bar 130 used for the power supply for the voltage of the single phase and the three phase is common to use the output.

Then, the distance between the bus bar 130 for grounding used in three phases and the bus bar installed to supply the R, S, T phase in the vicinity, and the bus bar 130 for grounding used in the single phase and u, The distance between the busbars installed to supply the v-phase is the distance between the T-phase busbars used for three-phase 380V and the ground busbars and the R-bus busbars used for three-phase 220V respectively. The distances between the are different from each other.

Accordingly, when the connector 200 used for the three-phase 380V is used for the three-phase 220V, the distance between the terminals is different and connection is impossible, thereby preventing damage to the device due to the connection of the different voltages.

In addition, the region corresponding to the three-phase 380V power source using the ground bus bar 130 in common and the region used for 220V are formed to have different colors.

Accordingly, the user is sure to distinguish between the 380V and 220V power source to prevent damage to the device due to the connection of the different voltages.

As described above, according to the present invention, it is possible to simultaneously supply power having various phases by one busway to supply power to various devices, and to supply power of different phases collectively by one busway, Even when various power supply is applied, damage factors of equipment by different power supply are eliminated in principle, and the busway body can be easily separated and used according to the installation location to minimize the constraints on use, and to ground the busway casing. To be sure, it is effective to prevent safety accidents due to poor grounding.
