Regardless of the type, the method using the screw connection structure in connecting the busbar busbar 10 and the branch busbar 30 has a hole processing for the busbar and tap processing for forming a screw surface on the inner surface of the hole. need. There is also a need for machining equipment for processing. The manufacturing and installation process is complicated and mass production and installation is difficult. Several manual processes are also required. The production and installation is expensive and time-consuming according to the workforce-dependent production and the installation structure of the complex bus bar (see Korean Patent Publication No. 10-2008-0103810).

Referring to the effect of the modular distribution panel of the present invention configured as described in detail as follows.

Modular distribution panel according to the present invention serves to convert the electric power supplied from the outside according to the load capacity in order to prevent electrical safety accidents and at the same time protect the load device by distributing the electricity to the power demand facilities at the same time cut off the overcurrent. It has a general function.

Wiring breaker 210 capable of drawing power from the power supply unit 100 side and cutting off the circuit, AC bus busbar 130 connected to the load side terminal of the wiring breaker 210, and power from the wiring breaker 210. The branch circuit breaker 310 for distribution to the load side, between the bus bus bar 130 and the terminal 320 of the branch circuit breaker 310 to branch the current path from the bus bus bar 130. The branch bus bars 131 to be connected are essential components of the distribution panel.

In case of industrial use, the circuit breaker 210 and the branch circuit breaker 310 are three-pole (three-phase) circuit breakers of R, S, and T poles, or four poles of R, S, T, and N poles. 4-phase) circuit breaker is used.

The external power input to the power supply unit 100 finally controls the energization of the branch circuit breaker 310 that distributes electricity to the loads according to whether the wiring breaker 210 is opened or closed. When a short circuit or short circuit occurs in the load circuits, the branch circuit breaker 310 is closed.

The distribution of the branch circuit breaker 310 is performed by connecting the branch bus bar 131 to the bus bus bar 130, and the branch circuit breaker 310 is connected to the terminal 320 provided at the end of the branch bus bar 131. It is connected and energized.

The energization process is a power supply unit 100-wiring breaker 210-bus bus bar 130-branch bus bar 131-branch circuit breaker 310 is a general power distribution course of the distribution panel.

One problem is the responsiveness of the circuit breaker that reacts when an abnormal phenomenon affecting energization such as load fluctuation or short circuit or leakage occurs under the condition that external power drawn from the power supply unit 100 is applied to the bus bus bar 130. And limitations caused by the energization mechanism. In fact, the branch busbar 131 connected to the busbar busbar 130 may generate sparks and high heat even if only a slight gap is opened mechanically, and if a severe phenomenon occurs such as a short.

In the case of the distribution panel in which the energizing course is the power supply unit 100-the circuit breaker 210-the bus bus bar 130-the branch bus bar 131-the branch circuit breaker 310, the branch circuit breaker The circuit breaker 210 operates to cut off the external power supply when the power supply unit 100 is closed and the electric power generated during the external power or the external power supply process is introduced into the power supply unit 100. That is, an energization pattern according to a series arrangement in which external power is energized to one busbar bar 130 and several branch circuit breakers 310 are directly connected to the busbar bar 130 through the branch busbar 131. Have

It is difficult to clearly distinguish the supply mechanism and the distribution mechanism with the naked eye because the distribution panel having such a conduction pattern exhibits a characteristic of structurally distributing through one bus bar 130. In the event of a partial fault in either the supply or distribution mechanism, it is not possible to sort out the parts and replace them with new or repaired parts.

The present invention can be selected as the general electrification course as described above, but can be changed separately through the supply module 200 and the distribution module 300.

For example, the power supply unit 100-supply module 200-circuit breaker 210-connection 400-distribution module 300-bus bus bar 130-branch bus bar 131-branch circuit breaker It is a course of (310).

The circuit breaker 210 is connected to each other, and the main distributor 230 and the main distributor 240 are integrated in the bus bus bar 110 that divides an external power source into each phase.

Therefore, the supply module 200 only serves as a supply side for energizing external power to the distribution module 300 and does not affect the distribution module 300 in the remaining matters except for the power characteristic factor. Above the main power unit, the wiring breaker 210 is first closed. This eliminates the problem of anomalies that can occur during the power delivery to the load side. The stability of main power management becomes a factor.
