Description

{DISTRIBUTION BOX BY USING COMPLEX TYPE DEHUMIDIFIER MEANS}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a composite wastewater switchgear, and more particularly, to a composite wastewater switchgear which is capable of preventing dehumidification by optimizing up / .

Most of the switchboards are made of steel or prefabricated panels and are made of a hinged door with a door for maintenance on one side. The inside of the switchgear is installed in a power receiver and a power line to supply power. The internal temperature of the switchboard enclosure is relatively higher than the external temperature due to the heat generated from the equipment itself, the geothermal heat transferred from the concrete floor, and so on. Therefore, when there is a sudden temperature difference between the inside and the outside of the switchboard Moisture is generated along with the convection in the apparatus, and condensation is formed in severe case. The condensation causes the line to corrode, resulting in an increase in the maintenance cost and shortage of electricity. In addition, Because the devices are built in, the internal temperature rises.

Especially when the switchboard is installed outdoors, the internal temperature of the cabinet is increased because the iron enclosure receives the solar heat directly. Excessive temperature rise in the switchgear reduces the operation efficiency and function of various parts and electric devices, and furthermore, it is difficult to maintain due to a fault due to high temperature, a short, etc. Especially, The devices are deteriorated to shorten the life span. Accordingly, various dehumidifying apparatuses are being sought to maintain the humidity and the temperature at a certain level to prevent property damage due to electrical accidents due to deterioration of electrical insulation, and to improve electrical quality and safety. In the above conventional technology, the heat exchange due to the temperature difference between the inside air and the outside air of the switchboard, and the natural convection phenomenon in which the hot air rises and the cold air descends and the blower for the forced air blow are used, The air can not be sufficiently lowered, the moisture itself can not be completely removed, condensation is generated on the inner wall, and short-circuiting occurs due to moisture and moisture.

However, the dehumidifying device for the machine tool controller is a chemical dehumidification method in which the air sucked from the upper part is dehumidified by the natural convection discharged through the dehumidifying agent to the lower outlet, and the circulation of the air is slow and it is difficult to remove the moisture in a short time. When dehumidification is required, a large amount of dehumidifying agent is required, which makes it necessary to increase the volume of the dehumidifying device. The silica gel and activated alumina used as a dehumidifying agent absorb moisture and store it. Therefore, In order to recycle, a drying operation using a fan or a heater is required. However, the dehumidifying ability can not be used during the drying time of the desiccant. In addition, when the heat sink is attached to both sides of the thermoelectric element, the power saving part, the control part, the cooling type drying part, and the electric heater part are all included in one body, The heat sink of the heat sink can discharge the dust together with the water droplet. However, the heat sink of the heat generating surface may cause dust to accumulate and deteriorate the lifetime of the thermoelectric element. If the drain hole is clogged due to dust or foreign matter, It can cause accidents, and all the machines are included in one body, which makes maintenance difficult.

In addition, there is a problem in that it is not enough to minimize the negative influences of the switchboard due to external climatic factors.

Therefore, there is a problem that there is no stable switchgear regardless of the external climatic factors of the switchboard.

As shown in Fig.

At this time, the housing 1 is formed in a rectangular box shape with a hollow volume using an iron plate, wood, synthetic resin, or the like. In order to open and close the inside and outside of the housing, An internal air circulation port 11 for circulating air and an internal air discharge port 12 for discharging indoor air to the outside are formed. In addition, the indoor air is forcedly sucked and circulated to the inside of the bottom part And a blowing fan mounting hole 13 in which a blowing fan 5 for forcibly discharging the blowing fan 5 is provided.

The dehumidifying agent 2 contains silica gel or activated alumina and is filled in the nonwoven fabric pack 21 having a predetermined volume corresponding to the volume of the space portion 14 formed in the housing 1, Along a guide 15 provided on both sides in the space 14 provided in the air conditioner 1 so as to be able to move up and down within a predetermined height in response to a change in the self weight depending on the wind power and moisture absorption of the air blowing fan 5 And functions to lower the humidity in the switchboard by absorbing the moisture and moisture contained in the air when the air in the switchboard is forcibly circulated by the blowing fan 5.

On the other hand, in the above-mentioned dehumidifying agent (2), silica gel is a silicate particle of a sturdy net structure formed by the reaction of sulfuric acid and sodium silicate, and has a very large surface area and a very excellent ability to absorb water, Lt; / RTI >

This means that after eating the commercially available steaming kimchi, there is a white paper on the bottom of a plastic bowl containing small granules. These granules are put in order to prevent the dried Kim from absorbing moisture and becoming damp, Instead, it absorbs moisture. These granules are silica gel. Such silica gel has the formula of SiO2? NH2O, and the small holes are connected to each other to form a sturdy net structure, and water, such as a solvent, enters between them, and is hardened. The silica gel has a very large surface area, It is a material that is widely used as a dehumidifying agent because of its excellent ability to absorb.

The silica gel which has already absorbed a large amount of moisture has a characteristic that the absorbing ability is poor, but a lot of heat is generated in the bus bar in the switchboard.

When the silica gel adsorbed on the cobalt compound is used, when the silica gel does not absorb moisture, the silica gel becomes blue. When the water absorbs moisture, the silica gel changes color to light red, indicating how much silica gel is absorbed and how much moisture is absorbed It can be easily grasped visually. The activated alumina in the above-mentioned dehumidifying agent (2) is amorphous alumina and has a characteristic of adsorbing ability. It absorbs moisture or oil vapor in gas and liquid, and when it is saturated, When the temperature in the switchboard rises above a predetermined temperature as described above, or when the water content of the dehumidifying agent (2) is determined to be equal to or higher than a predetermined threshold water content, indoor air is forcibly discharged to the outside A part of the moisture trapped in the dehumidifying agent 2 can be automatically or forcedly evaporated and discharged by the room air at a high temperature or the heat generated in the heater 9 for regenerating the dehumidifying agent, thereby being able to be continuously reused.

In addition, the regeneration timing weight switch 82 is provided between the pair of springs 81 so that the moisture content (W) of the dehumidifying agent (2) absorbing moisture and moisture contained in the air continuously in the switchboard Is turned on when the self weight of the dehumidifying agent 2 whose weight increases in accordance with the predetermined value W 'is equal to or greater than the predetermined limit value W', is greater than the elastic force of the springs 81. In the control section 7, When the weight detection switch 82 is turned "on ", it is recognized that the water absorbing ability of the dehumidifying agent is saturated and a series of dehumidifying agent regeneration functions can be performed.

The load cell 83 shown in the other embodiment of the regeneration timing detecting means 8 is an element for detecting the weight as an electrical signal and is provided with a dehumidifying agent 2 in a state of being installed at the center of the bottom of the dehumidifying agent 2 in the housing 1 Of the dehumidifying agent 2 is detected in real time and transmitted to the control unit 7 so that the control unit 7 causes the moisture content W of the dehumidifying agent 2 to be equal to or higher than a predetermined threshold value W ' , It is possible to carry out a series of dehumidifying agent regeneration functions until it has a predetermined weight capable of absorbing moisture and moisture again.

The heater 9 for regenerating the dehumidifying agent has a flexible plate shape and is detected through the regeneration timing detecting means 8 in a state in which the dehumidifying agent regeneration heater 9 is fixed in contact with or close to the dehumidifying agent 2 on the inner wall of the space portion of the housing 1 When the control unit 7 determines that the moisture content of the dehumidifying agent 2 has reached a predetermined limit value, it generates heat within a predetermined temperature range (for example, 120 to 200 캜) to evaporate moisture absorbed in the dehumidifying agent Playback function.

The control unit 7 controls the temperature of the water in the water supply system in accordance with the moisture content rate of the dehumidifying agent 2 detected through the temperature detection unit 6, To perform an overall control function according to the driving of the moisture removal devices 100 such as not only moving up and down the air flow direction changing mechanism 3 through the solenoid 4 but also controlling the driving of the blowing fan 5 do.

The moisture removal device 100 having the above-described structure may be provided with one or a plurality of the moisture removal devices 100 according to the overall size of the switchgear and the amount of heat and moisture generated therein, And the amount of the dehumidifying agent 2 installed in the housing 1 are determined.

In addition, as shown in FIGS. 1, 4, and 5, it may be detachably fixed to the interior of the switchgear 200 according to the casing state of the switchgear, the installed switchgear or the newly installed switchgear, It is preferable that the casing of the switchgear casing is thin or the switchgear panel is installed in a detachable manner on the inner wall surface. If the thickness of the switchgear casing is newly increased, It is preferable to be installed in a form embedded in the wall surface.

As described above, the control unit 7 controls the temperature of the interior of the switchboard, which is detected in real time via the temperature sensor 6, or the moisture content rate of the dehumidifying agent 2 detected through the regeneration timing detecting unit 8 The air flow direction changing mechanism 3 is raised or lowered through the solenoid 4 so as to circulate or discharge the internal air or perform the regeneration function for the dehumidifying agent 2.

(For example, 30 to 45 degrees Celsius) as a result of judging the temperature inside the control panel detected by the control unit 7 through the temperature sensor 6, the control unit 7 controls the flow of air through the solenoid 4, 4 and 6, the inner air circulation port communication hole 311, which is formed in the inner wing 31 of the air flow direction conversion port 3 by raising or lowering the direction changing port 3, And the inner air circulation port 11 formed inside the upper portion of the inner air circulation hole 11.

Therefore, after the indoor air forcedly sucked by the blowing fan 5 passes through the dehumidifying agent 2 in the housing 1, the indoor air circulation formed in the inner wing 31 of the air flow direction changing mechanism 3 Since the circulation route is formed to flow back into the interior of the switchgear through the external communication hole 311 and the internal air circulation hole 11 formed inside the upper portion of the housing 1,
