Description

DUST REDUCTION DISTRIBUTINGBOARD

The present invention first relates to a water switchgear that can be reduced, and more particularly, to a water switchboard that can reduce dust that can reduce the dust contained in the water switchboard.

Generally, a switchgear is a power system that receives electricity from a power plant and distributes it, and can monitor, control, and protect the power system.

In the switchboard, various switches, relays (relays), etc. are regularly arranged and managed.

In addition, the switchgear consists of an operating lever that opens and closes the circuit breaker of the high-voltage main circuit, a switch of the low-voltage main circuit, a voltmeter, an ammeter, a power meter, an integrated power meter, and an over-current meter electricity to flow a high-voltage current.

This switchgear generates high heat from transformers, current transformers, transformers, etc. installed therein.

Accordingly, in order to cool the heat generated in the switchgear, an inflow portion into which the outside air flows is formed on the front surface of the switchgear to cool the inside of the switchgear through the outside air.

However, such a switchgear has a problem in that external dust and foreign substances are introduced into the inlet and are deposited in the switchgear, which may cause a malfunction of the device, such as a poor contact of a device mounted inside the switchgear.

The failure of the above-described device acts as a cause of a serious malfunction of the switchgear, which is a device using electricity, and in particular, there is a problem in that a fire caused by electric sparks may occur in a device forming a contact portion.

Accordingly, in the related art, in order to prevent the failure of the device due to the deposition of dust, the operator has to frequently remove dust from various parts of the switchboard and the contact portion.

In order to perform the above operation, there is a problem in that the operation of the switchgear must be stopped by shutting off the power of the switchgear.

Alternatively, in order to block dust from entering the outside air, a filter for filtering dust is provided at the inlet located at the front of the water distribution panel to filter the dust contained in the outside air, and then the outside air is supplied to the inside of the water switchboard.

However, the above method has a problem in that when the outside air passes through the filtration filter, resistance occurs when the outside air is introduced, and thus the efficiency of the outside air is reduced, and accordingly, the cooling efficiency of the water distribution panel through the outside air may be reduced.

In one embodiment, the capacity of the exhaust fan 310 may be designed to be smaller than the capacity of the intake fan 240.

That is, as the amount of exhaust discharged through the exhaust fan 310 is less than the amount of flow introduced through the intake fan 240, the pressure inside the main body 100 is maintained above the atmospheric pressure, thereby minimizing the dust flowing into the main body 100. I can do it.

The exhaust fan 310 may also control the amount of discharge of air inside the main body 100 to the outside of the main body 100 by adjusting the rotation speed by a separate control unit (not shown).

Looking at the driving state of the present invention with reference to Figures 5 and 6 are as follows.

First, as shown in Figure 5, the intake fan 240 is driven, the outside air is introduced into the housing 210 through the inlet 261 of the cover portion 260.

At the same time, the bet inside the main body 100 flows into the housing 210 through the second intake port 230 of the housing 210.

In addition, the intake fan 240 discharges the introduced outside air and the inside air into the body 100.

At this time, the reduction filter 250 provided in the intake fan 240 first filters the dust of the outside air and the inside air, and then discharges the outside air and the inside air into the body 100.

At this time. The outside air and the bet discharged through the intake fan 240 may freely rotate the rotating body 410 of the wind direction switching unit 400.

That is, the outside air and the inside air pass through the rotating body 410 and form a vortex to diffuse throughout the main body 100 to increase the cooling efficiency of the main body 100 through the outside air.

In addition, the outside air and the inside air that have passed through the rotating body 410 are entirely diffused into the body 100 and scattered and floated at the same time, thereby preventing deposition of dust contained in the outside air.

The ingress of dust can be prevented in advance.

On the other hand, referring to Figure 6, the driving of the intake unit 200 is stopped, the circulation of the outside air and the inside air inside the body 100 is stopped, and no more outside air is introduced.

The exhaust unit 300 stops driving in accordance with the intake unit 200 and a driving state to stop exhaust of the outside air and the inside air of the main body 100.

At this time, when the exhaust fan 310 of the exhaust unit 300 stops, the force for moving the door 323B-2 upwards disappears, and the door 323B-2, which has opened the outlet of the exhaust pipe 320a, is discharged ( It descends to the lower portion of 320a, and the outlet of the discharge pipe 320a is sealed.
