The present invention relates to a distribution panel structure in which a 3-pole switchgear is arranged. Especially, it is suitable for eliminating the risk of electric shock accidents due to the exposure of the energized part when repairing distribution boards and branch switchgear without opening or closing the main switch. It is intended to be.

In the conventional distribution panel, as shown in FIGS. 1 and 2, the main busbar 11 is disposed from the main switch 1, which is attached to the distribution board 100, and the main bus bar between the branch switch 2 on both sides therebetween. Insulation distance between phases in a state in which the branch switch 2 is separated by more than the width of the main switch 1 with the branch bus bar 21 having the downwardly bent portion 22 sequentially connected to each other is installed. By installing the busbars (11) and (21) at a certain distance in order to maintain them, the energized part is exposed excessively. Due to the large size of the distribution panel and the appearance of the distribution panel is increased as the capacity of the main switchgear 1 increases, the effort that requires a lot of work time because the main switchgear 1 must be opened and closed during the simultaneous repair work. I needed this Was.

Therefore, to solve the above problems, the present invention consists of an insulation terminal block connected to the main bus bar by a main switch and a connection terminal, and an insulator between the phases and a branch bus bar that is sequentially contacted with the main bus bar to connect the branch switch. The board is equipped with a branch switch mounting rail, which eliminates anxiety about ease of repair and electric shock accident, saving time and effort for repair and providing a compact distribution board without increasing the size of the distribution board due to the increase in capacity of the main switch. The purpose is to.

Hereinafter, described in detail with reference to the accompanying drawings of the preferred embodiment as follows.

In the distribution panel that connects the main switch 1 and the branch switch 2 to the main switch bar and the branch bus bar in order to be sequentially connected to the distribution board 100, as shown in FIGS. And an insulated terminal block 4 connected to the main bus bar 3 by the connecting terminal 31, and a mounting part 52 in which the main bus bar seating recesses 51 are arranged on both sides thereof, and a protrusion 53 at the center thereof. The upper surface is formed with an insulating plate 54 at regular intervals and provided with a through-hole 55 in the center, and at the same time, the groove 56 vertically formed at the bottom thereof is a main bus bar which is connected with a branch bus bar for a central contact and a fastening member ( 3) a bent piece having at least one or more phase insulators (5) inserted therein and a branch switch connection terminal (61) on both sides contacting the main bus bar (3) on one side and fixed to the main bus bar on one side Branch busbar (6) for main busbar contact with 62 and branch switch connection terminal on both sides A main part bus bar contact point branch bar (7) having a bent portion (72) inserted into the through hole (55) and a center lower part thereof, and an insulating pedestal for grounding and supporting the main part bus bar ( 8) and the branch switch (2) guide insertion rail (9) fixed to the power distribution plate (100), and reference numeral 10 in the drawing denotes a terminal block.

Referring to the effect of the present invention configured as described above according to the assembly state is as follows.

After mounting the insulated terminal block 4 in front of the main switch 1 of the distribution board 1, insert the central main bus bar 3 between the insulated terminal block 4 and the insulating support 8, and then 5) is sequentially connected and mounted according to the number of both side switchgear (2), and then the main bus bar (3) is inserted into the groove (51) of both mounting parts (52).

Thereafter, the central house bus bar 3 is connected and connected to the fastening member through the through hole 55 of the phase insulator 5 by the branch bus bar 7 having the bent portion 72, and both house bus bars are bent pieces. The connection part is connected to the fastening member by the branch bus bar 6 having the 62 to closely connect the branch switch 2 which is guided to the rail 9 at each of the two connection terminals 61 and 71.

Therefore, the present invention can be miniaturized distribution panel because the space between the main busbars are closely connected by the insulator (5) and the space between the branch busbars (6) and (7) is installed by the insulation plate (54). In case of maintenance of branch switchgear in the distribution panel, the interphase insulator is installed without breaking the main switchgear so that it can reduce the maintenance work time and effort such as reducing anxiety about electric shock accident. The effect is to save time and effort.
