Description

Modular multi-busbar branch device {MODULE TYPE BUS BAR BRANCH DEVICE}

The present invention relates to a busbar branching device, and more specifically, to a module that can configure branch wiring through a prefabricated module component according to the conditions of the branch power capacity of the installed location using a single busbar branching device. It is related to type busbar branching device.

In general, the widely used distribution method in the power system is to supply power directly from the substation to large consumers such as factories or buildings through a three-phase, four-wire distribution line, or to small factories or general households through a secondary transformer. This is a method of supplying, and in this case, the distribution board and distribution board are used.

Here, the distribution board plays the role of distributing high-voltage power received from the power company by system or purpose, and generally supplies power to multiple distribution boards.

In indoor wiring, a cabinet panel refers to a place where a main line is divided into each branch circuit, with switches installed for each branch circuit.

The distribution board in a house is a simple fixed arrangement of cut-out switches, but in the case of a building, at least on each floor, a distribution board made of steel is installed in the wall and has a completely open and close door.

These general switchboards and distribution boards are equipped with mold case circuit breakers (MCCB: Mold Case Current Breaker) and earth leakage breakers (ELB: Earth Leakage Breaker) when an earth leakage is detected, and are used to connect loads (lights, RECEPs, broadcasting device power, etc.) If a short circuit occurs when power is supplied, a cut-off operation is performed to prevent fire, etc.

Although the switchboard and distribution board are significantly different in terms of the voltage magnitude of the main power received, the basic structure of the power distributor that supplies the received main power to a plurality of branch boxes (breakers, etc.) is similar.

Figure 1 is a perspective view showing the configuration of a general power distributor according to the prior art.

The general power distributor shown in FIG. 1 includes a main busbar in which the main power supply is arranged vertically, and a branch busbar arranged perpendicular to the main busbar and connected to a branch box that receives branched power.

Specifically, a general power distributor includes a main wiring breaker (60) capable of drawing in power from the power supply side and blocking the circuit, and a plurality of alternating current bus bars (BUS BAR) connected to the load side terminal of the main wiring breaker. A bar 12, a plurality of branch circuit breakers 50 for distributing power from the main bus bar 60 to the load, and the main bus bar 12 for branching a current path from the main bus bar 12. It is composed of a branch busbar (14) connected between the bar (12) and the terminal portion of the branch wiring circuit breaker (50).

For example, in the case of industrial use, the main circuit breaker and the distribution branch circuit breaker may be a three-pole (three-phase) circuit breaker with R, S, and T poles, or a circuit breaker with R, S, T, and N poles. A 4-pole (4-phase) molded circuit breaker is used, and a single-phase, 2-wire molded case breaker can be used in the home power distributor.

In the power distributor shown in FIG. 1, the connection between the main busbar 12 and the branch busbar appears to be stable, but in order to maintain this connection, a plurality of branch wiring breakers 50 are at the same height as shown. must have

In the case of a distribution panel that distributes relatively low voltage power, branch circuit breakers of the same standard can be configured, but in the case of a distribution board that distributes high power for various purposes, circuit breakers of various sizes are provided depending on the capacity of the branch power. This is common.

This is because the busbar branch devices of distribution boards and distribution boards cannot be manufactured uniformly with a small number of fixed specifications, but are manufactured individually depending on the characteristics of the installation location, and each branch wiring circuit breaker must be selected from a variety of products sold separately. It is due to the business environment in which it is attached.

Accordingly, when the power distributor structure of FIG. 1 is applied in the manufacture of a busbar branch device for a switchboard (and a distribution board for certain purposes), there are significant restrictions on the selection of a branch circuit breaker.

In addition, in the illustrated power distributor structure, branch wiring circuit breakers 50 are arranged in the area next to the main busbar 12, which occupies a significant area, which acts as a burden on the installation area and does not ensure insulation between busbars. If this is not done, there is a problem that accidents may occur.
