Description

Electric automatic control panel with increased safety

The present invention relates to an electric automatic control panel with improved safety, in particular, to prevent corrosion due to moisture by using condensation, and to an electric automatic control panel with improved safety that can be safely and automatically extinguished in the event of a fire.

As is well known, the electric automatic control panel is provided with an electric device or an electric controller in the enclosure to control the operation of an external electric device, an electric device, an electric facility, etc. The use of automatic control panels has been widely expanded.

Since various electric parts are built in the automatic control panel, which is the brain of the electric facility, even if the electrical wiring is simplified as much as possible, there are many electrical wires that have to be entangled.

Therefore, when a fire occurs inside the automatic electric control panel due to a short circuit, short circuit, or the like, flames are transferred to the flammable electrical wiring coatings, and are quickly burned off by emitting toxic gas. In the fire of the electric automatic control panel, corrosion of the electrical wiring sheath is the main cause, and corrosion of the electrical wiring sheath is promoted in a high temperature and humid environment.

Accordingly, research is being actively conducted to lower the temperature and humidity of the automatic control panel, and various things have already been developed and used.

Both ends of the refrigerant line RL are connected to the external refrigerant supply line RL1 and the refrigerant discharge line RL2, respectively, and receive low-temperature refrigerant from an external refrigerant circulation supply device (not shown). The condensation water receiving container 23 is equipped with a condensation water drain line DL, is installed in the lower portion of the cooling plate 22, is disposed in the rear space S2, and the condensation water falling from the cooling plate 22 And is discharged to the outside through the condensation water drain line DL. In the present embodiment, although the condensation water receiving container 23 is mounted on the inner lower surface of the control panel main body 11, a separate fastening member is provided on the inner side or rear side of the control panel main body 11, if necessary. Needless to say, it is also possible to fasten and fasten through a medium. The first circulation fan 24 is installed in the lower portion of the partition 13, forcibly transporting the air in the front space (S1) to the rear space (S2). The air, which is forcibly transferred from the front space S1 to the rear space S2 by the first circulation fan 24, is in a relatively high temperature and humid state. The second circulation fan 25 is installed on the upper portion of the partition 13, and forcibly transports air in the rear space S2 to the front space S1. The air that is forcibly transferred from the rear space S2 to the front space S1 by the second circulation fan 25 is relatively low temperature and dry.

The fire extinguisher fixing member 31 is installed on the inner side upper surface of the control panel body 11, is disposed in the front space S1, and is made of a shape memory alloy. In the case of this embodiment, the main body connection portion 31a fixed to the upper surface of the control panel body 11, and the fire extinguisher support portion 31b for supporting the liquid fire extinguisher 32 for throwing in a vertical direction detachably, and in the upward direction A fire extinguisher fixing member 31 was applied to the structure having a fire extinguisher insertion guide portion 31c to guide the throwing liquid extinguisher 32 for insertion. The fire extinguisher fixing member 31 maintains the state shown in FIGS. 4 and 5, and when heated due to a fire, is deformed into a circular shape as shown in FIG. 7, and the liquid extinguisher 32 for throwing The fall from the fire extinguisher fixing member 31. The fire extinguisher fixing member 31 according to the present invention is not limited to this embodiment, and is usually supported so that the liquid fire extinguisher 32 for throwing is supported, and is modified so that the liquid fire extinguisher 32 for throwing falls when heated at high temperature. Any structure may be used as long as it is a shape memory alloy material. The liquid extinguisher for throwing 32 is inserted and fixed removably in the vertical direction to the extinguisher fixing member 31, and is disposed in the front space S1 located on the inner side upper side of the control panel main body 11. The liquid extinguisher for throwing 32 has a structure in which a liquid extinguishing liquid is filled in a case that is easily damaged by an external impact, and when the fire extinguishing liquid exposed to the outside of the shattered case evaporates during cooling, the combustion product is cooled and ammonia gas or Generates carbon dioxide gas to suppress chain chemical reactions, block oxygen around the combustibles, and extinguish fires quickly and reliably. Since the liquid extinguisher 32 for throwing is already commercialized and widely used, a detailed description thereof will be omitted. The fire extinguisher guide 33 is installed on the inner side upper surface of the control panel main body 11, is disposed in the front space (S1), prevents the discharging of the liquid fire extinguisher 32 for throwing fixed to the fire extinguisher fixing member 31 do. In addition, the fire extinguisher guide 33 also functions to guide the liquid extinguisher 32 for throwing into place when it is inserted into or removed from the extinguisher fixing member 31. Of course, the fire extinguisher guide 33 may be installed on the inner upper side of the control panel main body 11 as necessary. The extinguishing liquid diffusion member 34 guides the liquid extinguisher 32 for dropping from the extinguisher fixing member 31 to the center direction of the control panel main body 11 while diffusing the extinguishing liquid of the liquid extinguisher 32 for spraying in all directions. Equipped with an inclined surface (34a), is installed on the inner side of the control panel body 11, is disposed in the front space (S1) located under the fire extinguisher fixing member (31). The crushing projection 35 is provided to protrude on the inclined surface 34a of the digestion liquid diffusion member 34 to crush the case of the liquid extinguisher 32 for throwing falling from the extinguisher fixing member 31. The shape and shape of the crushing projection 35 is not limited to a specific shape, and any material may be used as long as it can crush the case of the throwing liquid liquid extinguisher 32.

The operation state of the dehumidifying unit will be described with reference to FIG. 6 as follows.

First, in the state in which the cooling plate 22 is sufficiently cooled by the low-temperature refrigerant supplied to the refrigerant line RL through the refrigerant supply line RL1 and the refrigerant output line RL2, the first circulation fan 24 And when the second circulation fan 25 is operated, the internal air of the rear space S2 is introduced while the internal air of the front space S1 flows into the lower portion of the rear space S2 by the first circulation fan 24. The second circulation fan 25 flows into the upper portion of the front space S1.

The air flowing into the lower portion of the rear space S2 by the first circulation fan 24 is cooled while being moved upward along the cooling plate body 22a and cooling fins 22b of the cold cooling plate 22, Condensation is generated in the cooling plate 22 having a relatively low temperature due to the temperature difference between the flowing air and the cooling plate 22. Accordingly, the air flowing to the upper portion of the rear space S2 and forcibly circulated to the front space S1 through the second circulation fan 25 maintains a low temperature while drying. On the other hand, condensation generated on the outer surface of the cooling plate 22 flows down and falls to the condensation water receiving container 23 and then discharged to the outside through the condensation water drain line DL.

The dry, low-temperature air flowing in the upper portion of the front space S1 by the second circulation fan 25 flows in the downward direction, and comes into contact with the electric devices disposed in the front space S1 from the electric devices. The temperature is increased by taking away heat, and water vapor in the air in the front space S1 is contained. Therefore, the air flowing to the lower portion of the front space S1 and forcedly circulated to the rear space S2 through the first circulation fan 24 maintains a relatively humid and high temperature state.

When the internal air of the control panel housing 10 is continuously circulated by the first circulation fan 24 and the second circulation fan 24, the internal temperature and humidity of the electric automatic control panel are effectively and simultaneously lowered.

On the other hand, when the outside air is introduced into the control panel housing 10, the cooling and dehumidifying functions may be deteriorated, so that the front space of the control panel main body 11 is closed by the control panel cover 12, and the front space ( It is preferable that S1) and the rear space S2 are sealed with the outside without a separate ventilation hole. On the other hand, the non-explanatory reference numeral '11a' denotes an electric wire, and it is preferable to maintain the sealed condition as much as possible by using a separate airtight member. For reference, since the airtight member is also commercialized, it will be omitted.

Referring to Figures 5 and 7 will be described the operating state of the fire extinguishing unit as follows.

First, the liquid fire extinguisher 32 for throwing is elastically fixed to the fire extinguisher fixing member 31 as shown in FIG. 5 by pushing the liquid fire extinguisher 32 for throwing upward in the upward direction of the fire extinguisher fixing member 31. When the fire extinguisher fixing member 31 is heated due to a fire in the state (P1 position on FIG. 7), the fire extinguisher fixing member 31 of the shape memory alloy material is deformed into a circular shape as shown in FIG. The liquid fire extinguisher 32 for throwing will fall freely.

The liquid dropping fire extinguisher 32 for free-falling is first crushed while striking the crushing projection 35 and then guided along the inclined surface 34a of the extinguishing liquid diffusion member 34 to fall in the center direction of the control panel body 11 (See position P2 on FIG. 7). At this time, some of the extinguishing liquid of the throwing liquid extinguisher 32 is poured out from the shredded throwing liquid extinguisher 32 and scattered in all directions by the inclined surface 34a, and a part of the shredding liquid extinguisher 32 ) And collides with surrounding structures and scatters everywhere.

Accordingly, in the event of a fire, automatic and automatic fire suppression is performed safely, quickly and reliably regardless of whether or not power is supplied.

On the other hand, the liquid fire extinguisher for throwing 32 is disposed in the front space located on the inner side upper side of the control panel main body 11, and has a structure that falls along the side surface of the control panel main body 11, and also the liquid fire extinguisher for throwing 32) is a method of crushing while colliding with the crushing projection 35, so the distance between the liquid extinguisher 32 for throwing and the crushing projection 35, that is, the dropping distance of the liquid extinguisher 32 for throwing is minimized. Since it is possible to minimize interference with electric devices and electric wirings inside the automatic electric control panel, there is also an effect of efficiently using the space inside the automatic electric control panel.

Particularly, as mentioned above, in a state in which the front surface of the control panel main body 11 is closed by the control panel cover 12, the front space S1 and the rear space S2 are closed to the outside without separate ventilation holes. If possible, a safer, faster and more reliable fire suppression effect can be expected.

As described above, the present invention is not limited to the present embodiment, and various modifications may be carried out as necessary or extended to similar fields.

As an example, the present invention was invented for an electric automatic control panel, but it can also be applied to a distribution panel or a distribution panel in which electrical devices are embedded.
