The present invention relates to a switchboard, and in particular, by arranging the breaker to use the space, and by connecting the bus bar and the breaker freely according to the arrangement, capacity, number of poles of the breaker, to prevent the generation of dead space due to the breaker installation The present invention relates to a switchgear capable of efficiently utilizing a limited space of a switchgear.

For efficient and stable use of externally supplied power, power should be distributed by capacity and use through switchboards. To this end, a switchboard is used to distribute power to each customer or branch circuit, and the switchboard has a branch circuit breaker, a switchboard that distributes power to each customer or branch circuit, converts high voltage power into low voltage power, and converts the converted power into low voltage power. A distribution panel (or switchboard) for distribution and supply, and a motor distribution panel for providing a separate circuit for a load of a large amount of power, such as a motor. In particular, the switchboard may be configured as one component of a power circuit independently, such as a distribution panel, or may be configured as an accessory configuration of a large configuration such as a distribution panel. In the following description of the related art and the present invention, a configuration in which power is distributed to a plurality of branch circuits will be collectively described as a switchboard.

Such a switchboard is composed of a case, a breaker, and a busbar (or a cable) for the distribution of power and the protection of each circuit receiving the power.

1 is an exemplary view showing an example of a general switchboard, Figure 2 is a side view illustrating the busbar coupling form.

1 and 2, the switchboard is a bus booth bar 12 (or first booth bar), a charity booth bar 13, or a branch booth bar or a second booth bar, and a branch breaker 23 to distribute power. , Or a branch circuit breaker or an auxiliary circuit breaker) and a bus bar holder 14.

The bus bar 12 is directly connected to a bus line or a lead wire to which power is supplied, or is connected by a parking short circuit (not shown), and is also connected to the charity bus bar 13 by a fastening means 27. Through this, the bus bar 12 serves to supply the power supplied through the bus bar through the combined charity bus bar 13. The bus bar 12 is composed of a plurality of metal bus bars to correspond to the plurality of phases as shown in FIG. 1 and arranged side by side in one direction. One side end of the bus bar 12 is coupled to the bus bar fixing bar 14 for fixing the bus bar 12 to be spaced apart from the installation surface by a predetermined height.

The own bus bar 13 is connected by the bus bar 12 and the fastening means 27 and receives power through the bus bar 12 to transfer to the branch circuit breaker 23 or the branch circuit. The charity booth bar 13 is arranged to intersect the bus booth bar 12 as shown in the drawing. The charity bus bar 13 has a bent part 26 for coupling with the bus bar 12, and the fastening hole 29 formed in the bent part 26 and the fastening hole 30 at a position corresponding thereto. It is coupled with the bus bar 12 by the fastening means 27 coupled through. The charity bus bar 13 maintains a constant distance from the bus bar 12 that is not connected by the bent portion 26, thereby preventing short circuits and arcing. On the other hand, the branch wiring breaker 23 is connected to one end or both ends of the charity bus bar 13, as shown.

In this way, the power distribution board formed by the bus bar 12 and the charity bus bar 13 can prevent a short circuit due to contact between the bus bars 12 and 13, and provide a long life when the planned wiring is connected. It can be guaranteed, and there is an advantage that enables communication of relatively large power. In addition, the use of a bus bar in the form of a metal bar (Bar), the circuit of the switchboard is concise and advantageous in detecting the abnormality of the circuit, there is an advantage that it is possible to configure the breaker and the wiring, that is, the bus bar in a relatively narrow space.

However, the conventional switchgear using a busbar has a problem in that it is not easy to couple breakers of different capacities to both ends of the branch busbar 13. Specifically, the parking breaker (not shown) or the branch breaker 23 varies in size depending on the capacity, and thus, the thickness of the cable 35, the connector 36, and the charity bus bar 13 that can be connected to the input side 23a. And size varies. Therefore, it is difficult to couple the branch circuit breakers 23 having different capacities at both ends of one of the charity bus bars 13, thereby creating a space in which a breaker cannot be installed.

In order to solve this problem, conventionally, as shown in FIG. 1, the charity bus bar 13 is cut and two breakers 23_1 and 23_2 having different capacities are arranged on the same line using the cable 35 and the connector 36. It is used as much as possible. However, in this case, there is a disadvantage in that it is cumbersome to manufacture a busbar in the form of a cable by cutting the charity bus bar 13 and combining the cable 25 and the connector 26. In addition, the connector 36 is connected to the bus bar 12 together with the own bus bar 13 by the fastening means 27, thereby increasing the resistance of the connection point and thereby damaging the bus bars 12 and 13. Many problems are caused.

Therefore, an object of the present invention is to arrange the circuit breaker to use the space, and by connecting the bus booth bar and the breaker freely according to the arrangement, capacity, number of poles of the circuit breaker, to prevent the generation of dead space due to the breaker installation, It is to provide a switchgear capable of efficiently utilizing the space of a limited switchgear.
