The control panel includes a metal cabinet that can be opened and closed, and various types of circuit breakers, switches, fuses, relays, power and signal cables, etc. disposed inside the cabinet.

However, since the control panel is operated with the door closed for safety, the control panel tends to be overheated during operation, and is affected by dust or various noxious gases introduced through the ventilation opening. For example, the internal humidity increases due to the condensation phenomenon caused by the temperature difference between the inside and the outside, so that the cable is corroded, a fire due to electric leakage occurs, performance deteriorates, and life is shortened.

In addition, since the control panel installed in the underground space with poor air permeability operates in a concentrated polluted gas or toxic gas atmosphere, the life of the internal cable, the breaker, and the fuse is shortened. In some cases, The communication of the mobile terminal is interrupted.

To solve this problem, a ventilation fan is installed inside the cabinet of the control panel, and the air inside the control panel is forcibly discharged. In fact, the air discharge efficiency is not so good. This is because the complicated control components and cables are closely packed inside the cabinet, which makes it difficult to smoothly flow the air.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Basically, the safety control panel 10 according to the present embodiment, which will be described later, uses the horizontal channel 18 and the vertical channel 14 provided therein as air passages to supply air for cooling and drying, So that the temperature and humidity of the inside of the cabinet 12 can be easily controlled. In addition, since the air curtain forming portion is not allowed to penetrate the inside of the cabinet 12, the inside environment is clean.

A safety control panel having an air conditioning function according to the present embodiment includes a cabinet having an internal space and an exhaust port formed on a side thereof; A wiring frame installed inside the cabinet and having a plurality of vertical channels for providing vertical wiring paths and a plurality of horizontal channels connected to the vertical channels for providing horizontal wiring paths; ; A plurality of control electrical components arranged around the vertical channel and the horizontal channel; A cable passing through the wiring channels of the vertical channel and the horizontal channel and electrically connecting the electric components; A plurality of axial flow blowers installed in the wiring channels of the vertical channels and the horizontal channels together with the cables and blowing the cooling air; An air curtain forming unit installed in an exhaust port of the cabinet for stopping and stopping the operation of the axial flow blower to block the penetration of contaminants through the exhaust port; A controller for controlling operations of the axial flow blower and the air curtain forming unit; And a sensor unit disposed in an inner space of the cabinet and sensing temperature and humidity inside the cabinet in real time to transmit to the controller and causing the controller to drive the axial flow blower and the air curtain forming unit.

FIG. 1 is a front view of a safety control panel 10 having an air conditioning function according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing an enlarged portion of a safety control panel 10. 3 is a view for explaining the overall configuration of the safety control panel shown in FIG. 1, and is a view for explaining the operation of the safety control panel 10. As shown in FIG.

As shown, the safety control board 10 according to the present embodiment includes a cabinet 12, a wiring frame 30, an electric component, a cable, a plurality of axial flow blowers 22, an air conditioning knob forming portion 51, , And a sensor unit.

First, the cabinet 12 is manufactured by bending a metal plate, and has an internal space 12a for accommodating the various components. The inner space 12a is opened and closed by a separate door (not shown). When the door is closed, the inner space 12a is sealed and opened, and the inner space 12a is opened forward.

Further, an exhaust port 12c is formed on the side of the cabinet 12. The exhaust port 12c is a slit-shaped through hole having a predetermined width and extending in the vertical direction, and has a screen net 12b therein. The screen net 12b prevents penetration of insects such as flies or mosquitoes into the internal space 12a of the cabinet 12. [

The reason why the exhaust port 12c is elongated in the vertical direction is that the heat generated in the internal space can be discharged directly to the side without rising. That is, it is intended to maximize the discharge rate of heat.

In addition, a plurality of air curtain forming portions 51 are provided inside the exhaust port 12c. The air curtain forming portion 51 is a blower for discharging downward flow air and is mounted close to the screen net 12b through suitable supporting means. The air ejected from the air curtain forming portion 51 rubs on the inner surface of the screen net 12b and vertically downward to cut off the exhaust port 12c using wind pressure.

The air curtain forming portion 51 stops when the axial flow blower 22 to be described later is operated and operates while the axial flow blower 22 is stopped, thereby blocking the penetration of contaminants through the air outlet, that is, dust and moisture.

The wiring frame (30) includes a plurality of vertical channels (14) and horizontal channels (18). The vertical channel 14 is a member in the form of a square pipe providing a wiring passage 14a extending in the vertical direction, and has a plurality of through holes 14b on its side. The length or position of the vertical channel 14 is designed to vary as needed.

In addition, the horizontal channel 18 has horizontally extending wiring passages 18a, and includes a plurality of through holes 18b that are open to upper and lower portions. The horizontal channel 18 also includes a cover 18c. The cover 18c is a member for opening the wiring passage 18a. When the cover 18c is removed, the wiring passage 18a is opened to adjust the position of the cable 53 or perform other necessary operations. The length or height of the horizontal channel 18 can vary.

In fact, the positions of the vertical channel 14 and the horizontal channel 18 depend on the optimal placement of the electrical components housed within the cabinet 12. [ That is to say, it depends on the location of the electrical components.

A cable 53 for connecting electric components is wired in the wiring paths 14a and 18a of the vertical channel 14 and the horizontal channel 18. [ The cable 53 may include a power cable and a signal cable. The cable 53 passes through the wiring passages 14a and 18a in the longitudinal direction and through the through holes 14b and 18b to the outside and is connected to the surrounding electric parts.

The above-described electric parts are various parts for electric and communication used in a general control panel. The main parts of the main circuit breaker 40, the bus bar 42, the controller 44, the fuse 46, the individual breaker 48 As well as other electrical and electronic components.

Meanwhile, a plurality of axial flow blowers 22 are installed in the vertical channel 14 and the horizontal channel 18. The axial flow blower 22 is operated by a controller 32 to be described later and implements air flow inside the wiring paths 14a and 18a of the vertical channel 14 and the horizontal channel 18. [ That is, air flows in the longitudinal direction of the wiring paths 14a and 18a. The spacing of the axial flow blower 22 relative to the vertical channel 14 and the horizontal channel 18 varies as needed.

The axial flow blower 22 forms an air flow atmosphere in the wiring passages 14a and 18a so that the air is entirely directed to the screen net 12b as shown in Fig. That is, the air is pushed toward the screen net 12b to be discharged. Air stagnation does not occur anywhere in the cabinet 12.

On the other hand, an air supply pipe 20 is provided together with the cable 53 in the wiring paths 14a and 18a. The air supply pipe 20 receives the pumped air from the air pump 34 of FIG. 4 into the wiring paths 14a and 18a and guides them into the wiring paths 14a and 18a. In particular, a plurality of discharge holes 20a are formed in the air supply pipe 20. The discharge hole 20a is a hole through which the air flowing inside the air supply pipe 20 is discharged.

The air discharged through the discharge hole 20a is applied to peripheral electric parts to cool the electric parts. The air discharged through the discharge hole 20a is in a state of being cooled through the cooling part 38. [ The distance of the electric component to the discharge hole 20a is closer than 15 cm. By narrowing the gap between the discharge hole 20a and the electric parts to be cooled in this manner, the cooling wind can hit the electric parts in a cold state.

For reference, in the conventional control panel, since the blower is installed in the lower part of the cabinet and the air discharged from the blower is heated while rising, the temperature of the air reaching the upper side of the cabinet becomes equal to the temperature of the exothermic part, Almost none.

A controller 32, a sensor unit 28, an air pump 34, a filter 33, a cooling unit 38, and a condensing unit 36 are installed in the cabinet 12.

First, the air pump 34 compresses external air and pumps the air into the cabinet 12. [ The air pumped by the air pump 34 is filtered through the filter 33 and then passed through the cooling section 38. The air passing through the cooling section (38) passes through the condensing section (36) while being cooled to the set cooling temperature. The condenser 36 condenses air in a state where the saturation temperature is lowered due to cooling to completely remove the moisture contained in the air.

As a result, the outside air passes through the filter 33, the cooling section 38, and the condensation section 36 in order to be in a cool, dry and purified state.

The air that has passed through the condensing section 36 flows into the air supply pipe 20 and is discharged through the discharge hole 20a while flowing through the air supply pipe 20 so as to be blown around the wiring paths 14a and 18a, .

The sensor unit 28 includes a moisture sensor 24 and a temperature sensor 26. The humidity sensor 24 senses the humidity inside the cabinet 12 and the temperature sensor 26 senses the temperature inside the cabinet 12 in real time and transmits the sensed data to the controller 32.

The controller 32 operates the air pump 34, the cooling unit 38, and the condenser 36 based on the temperature and humidity information received from the sensor unit 28. If it is not necessary to adjust the temperature and the humidity, the air curtain forming unit 51 is operated only to prevent the contaminants from penetrating into the cabinet 12.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
