In order to ensure safety and to repair switchgear, branch connector type branch terminal is formed in case formed of flame-retardant insulator that can solve the risk of electric shock accident due to exposure of energized part. It is a prefabricated switchgear and branch connector that improves workability at the same time and can be reassembled by moving from phase to phase without additional main busbar processing when circuit addition or deletion change occurs.

What is distribution panel?

 It is a device that serves as the inlet of the converter that distributes the electric power supplied from the outside in the industrial equipment circuit and the indoor / outdoor circuit of the building to the capacity of the load.It consists of internal equipment (circuit breaker such as circuit breaker and earth leakage breaker) on its inner plate. It is an electric control device that prevents accidents by cutting off the circuit from the main bus in case of overcurrent or short circuit.

 As an installation place, it is installed on the inside and outside walls of the building, outside walls, or in a separate room, and checks and maintains the inside of the distribution panel at any time in case of an accident.

In the conventional distribution panel of the present invention, as shown in FIG. 1.2.3, the main busbar 11 is connected to the main switch 1 mounted on the base 100 surface of the distribution box 110, and both main busbars 11 are provided. The branch switchgear 2 is connected to the branch bus bar 21 is connected to the main bus bar 11, respectively.

At this time, the main busbar 11 and the branch busbar 21, and the branch switchgear 2 opposite to any branch switchgear 2 are designed to have a sufficient separation distance to ensure mutual insulation.

On the other hand, the main busbar 11 is spaced between the branch switchgear 2 and the branch switchgear 2 and between the branch busbars 21 so that a sufficient insulation distance is maintained even when the single-phase branch switchgear 2 is connected. The spacing should be far enough apart.

As described above, the switch mounting structure of the conventional distribution panel has a main bus bar 11 and a branch bus bar at a predetermined distance to maintain the insulation distance between phases in a state where the branch switch 2 is spaced more than the width of the main switch 1. By installing (21), the energized part was exposed excessively, and there was a high risk of electric shock accidents during maintenance and replacement of equipment.

As a result, the user of the other track that does not need to be repaired should perform work while the main switch 1 is turned off during the repair work, which is disadvantageous in that power is not used until the repair work is completed. .

In addition, as the distance (a) of the breaker or the switch is farther away, the size of the enclosure 110 becomes larger, and as the capacity of the main switch 1 increases, the distribution panel enclosure becomes larger, thereby increasing the manufacturing cost and the distribution box. Due to the heavy steel, there was a disadvantage in that the worker had difficulty in installing the distribution board.

In particular, since there is no standard arrangement structure for the circuit breaker and the switchgear arranged in the distribution panel during the installation work of the circuit breaker or the switchgear, the arrangement of the main busbar 11 and the branch busbar 21 according to the configuration of the wiring line is eloquently spoken. Since there is no other way than to do it each time, there was a problem that a lot of inconvenience occurs even when producing a distribution board.

That is, it is difficult to select the position for fixing the circuit breaker and the switch installed in the distribution board, and if the position of the screw fastening hole for fixing the switch is not correct, the position of the screw fastening hole should be selected again and formed on the surface of the base 100. There were many problems.

In particular, when the circuit breaker is arranged differently or replaced due to a circuit change during maintenance, the main bus bar 11 should be additionally processed by the disassembly branch bus bar 21 and the fastening screw 12 hole. There is a disadvantage in that the bar 11 needs to be replaced, which is time and costly.

 The present invention solves the above problems and solves the risk of electric shock accidents due to the exposure of the energized part during the maintenance of the switchgear in the distribution panel, and at the same time to improve the safety by miniaturizing the size of the distribution panel enclosure, the addition of circuits, deletion and modification In this case, an object of the present invention is to provide a prefabricated distribution panel and a steel distribution panel adopting a branch connector to achieve assembly workability with a branch connector that can be processed without processing a separate main busbar.

 In order to achieve the above object, the present invention provides a distribution panel comprising a main busbar in which a plurality of phases (R phase, S phase, T phase, N phase) are stacked vertically and sequentially arranged; A case formed of a flame-retardant insulator, a plurality of connectors inserted into the case, bent, silver-plated connectors, terminals formed to be in close contact with the main busbar by spring force at the center of each connector, and The upper connector is attached to the groove formed on the upper portion of the upper and lower caps for distinguishing the color by phase, and the branch connector is provided with a hole for identifying the thermal management color conversion tape attached to the upper portion of the connector alone formed on the upper case, When the branch connector is assembled to the main bus bar, it is characterized by constituting a prefabricated distribution board adopting a terminal system that compresses the main busbar and the connector by the force of the spring assembled in the center of the plurality of connector terminals.
