Abstract

The present invention relates to an arc ventilation system of a multi-stage distributing board, and more particularly, to an arc ventilation system of a multi-stage distributing board having an arc ventilation detour path, capable of preventing an arc generated in a lower compartment from damaging an upper compartment. The arc ventilation system of a multi-stage distributing board according to an embodiment of the present invention includes a first compartment provided at a first stage of an enclosure of the distributing board, a second compartment provided at a second stage located above the first stage, a side arc ventilation compartment provided at one side of the first compartment and the second compartment, and a middle arc induction compartment provided between the first compartment and the second compartment and communicating with the side arc ventilation compartment.

First claim

What is claimed is:

1. An arc ventilation system of a multi-stage distributing board, the system comprising:
a first compartment provided at a first stage of an enclosure of the multi-stage distributing board;
a second compartment provided at a second stage located above the first stage;
a side arc ventilation compartment provided at one side of the first compartment and the second compartment; and
a middle arc induction compartment provided between the first compartment and the second compartment and communicating with the side arc ventilation compartment,
wherein the middle arc induction compartment is provided with a plurality of first flaps rotatably installed on a lower surface thereof.

2. The arc ventilation system of claim 1 , wherein the middle arc induction compartment is provided with first openings formed on left and right side surfaces, respectively.

3. The arc ventilation system of claim 1 , wherein the middle arc induction compartment is provided with a second flap rotatably installed on a rear surface thereof.

4. The arc ventilation system of claim 1 , wherein a lower arc induction compartment is provided in a lower corner of a cable compartment provided at the rear of the first compartment and the second compartment.

5. The arc ventilation system of claim 4 , wherein the middle arc induction compartment is provided with second openings formed on left and right surfaces thereof, respectively.

6. The arc ventilation system of claim 4 , wherein the lower arc induction compartment is provided with a third flap installed on a front surface thereof in an inclined direction.

7. The arc ventilation system of claim 4 , wherein a fourth flap, a fifth flap, and a sixth flap are rotatably installed on upper surfaces of the second compartment, a bus bar compartment, and the cable compartment, respectively.

8. The arc ventilation system of claim 4 , wherein the side arc ventilation compartment is provided with a lower arc introduction compartment at a position corresponding to the lower arc induction compartment.

9. The arc ventilation system of claim 8 , wherein the lower arc introduction compartment has a side surface opened, wherein the side surface is brought into contact with the lower arc introduction compartment.

10. The arc ventilation system of claim 4 , wherein the enclosure and the side arc ventilation compartment are provided with an upper arc ventilation compartment disposed on upper parts thereof.

11. The arc ventilation system of claim 1 , wherein the side arc ventilation compartment is divided into a plurality of compartments.

12. The arc ventilation system of claim 1 , wherein the side arc ventilation compartment is provided with a middle arc introduction compartment at a position corresponding to the middle arc induction compartment.

13. The arc ventilation system of claim 12 , wherein the middle arc introduction compartment has a side surface opened, wherein the side surface is brought into contact with the middle arc induction compartment.

14. The arc ventilation system of claim 1 , wherein the enclosure comprises a plurality of enclosures, wherein the plurality of enclosures are arranged in parallel in a contacting manner, and
wherein the side arc ventilation compartment is installed at each of a right side of a rightmost enclosure and a left side of a leftmost enclosure among the plurality of enclosures.
