Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic control panel and a corrosion-

The present invention relates to an automatic control panel and a system for preventing the corrosion of a switchgear, and more particularly, to an automatic control panel and a control panel for automatic control of moisture inflows, which are generated in a water treatment facility by forcibly introducing clean outside air into a control panel and a switchgear installed in the water treatment system. And an automatic control panel for preventing inflow into a switchboard and a switchboard corrosion prevention system.

The switchboard is used for power load control and power factor control by distributing and receiving main electricity.

When such a switchboard is used in a water treatment system, a machine breakdown is frequent due to the harmful gas and moisture generated in the water treatment process, and therefore the machine replacement is frequently performed, resulting in a large cost.

In addition, there is a risk of machine breakdown and accidents due to the fact that the heat generated during machine operation is not released properly.

Therefore, there have been various attempts to control such noxious gas, moisture, and temperature.

First of all, the patent application No. 10-2007-0103730 entitled "Temperature and Humidity Control System for Switchboard" has a temperature and humidity sensor and an automatic control unit installed inside the switchgear, and a ventilation hole and a forced circulation fan are installed on one side of the switchgear housing, When the temperature and humidity to be set are set, the temperature and humidity sensor transmits the sensed temperature and humidity to the automatic control unit in real time according to the set temperature and humidity value. The automatic control unit receives the temperature and humidity of the inside of the control panel by appropriately controlling the ventilation hole and forced circulation fan, Temperature and humidity control apparatus capable of efficiently controlling temperature and humidity.

However, in the case of the above-mentioned "apparatus for adjusting the temperature and humidity of the busbuilding ", there is a problem in that corrosion of machinery due to noxious gas can not be prevented because the noxious gas causing corrosion in the water treatment system can not be blocked.

No. 10-0815273 entitled "a power supply and distribution system equipped with a dehumidifying device ", a dehumidifying device is attached to an inner wall of a cabinet, and an inner space is divided into a heat dissipation chamber and an endothermic chamber which are separated from each other and a heat dissipation chamber is communicated with an exhaust hole A housing having a through-hole formed therein for allowing air to flow into the cabinet; A thermoelectric module accommodated in a central portion of the housing and having heat radiating fins arranged at one side toward a heat dissipating chamber and having heat dissipating fins arranged at a low temperature portion toward the other end toward the heat absorbing chamber; A heat dissipating fan disposed on the heat dissipating chamber side of the housing for sucking air through the through hole of the housing and discharging the heat exchanged air through the heat dissipating fin through the exhaust hole of the cabinet; A blowing fan disposed on the endothermic chamber side of the housing for sucking the humidifier through the through hole of the housing and discharging the dehumidified dry air while being cooled through the heat absorbing fin into the cabinet; And a drain water tank provided at the bottom of the heat absorbing chamber of the housing for collecting the condensed water that is formed at the heat absorbing fin and discharging the condensed water to the outside of the cabinet; A humidity sensor for detecting the humidity of the air in the cabinet and transmitting the humidity to the control unit of the control panel is disposed inside the cabinet of the switchboard system; The control section of the control panel has proposed a power distribution system having a dehumidification device for driving the dehumidification device when the humidity value input from the humidity sensor is equal to or higher than a set value.

However, in the case of the above-mentioned "switchgear system equipped with a dehumidifier," the ingress of harmful gas can not be prevented like the above-mentioned "switchgear temperature / humidity control device ", and the configuration for controlling the temperature and humidity inside the switchgear is complicated.

In order to overcome the disadvantage that the above-mentioned invention is difficult to prevent inflow of harmful gas, the invention has been accomplished. Patent No. 10-0783441 entitled "Conservation Type Sealed Switchgear ", forcibly introduces outside air into the interior of the switchgear, To prevent corrosion of parts caused by moisture or harmful substances such as chlorine gas or ammonia by washing components installed inside the switchgear.

To this end, an air supply duct for supplying air from the upper end of the switchboard to an air conditioner of a building installed in a switchboard or outdoors and sucking outside air; An exhaust duct extending from the lower end of the power transmission / reception panel to an air conditioner of a building installed in a power and control panel or outdoors to discharge air used for cleaning components constituting a power / A filtering unit installed in the air supply duct to remove foreign matter from the air flowing through the air supply duct; The air supply duct is installed at the upper end of the power transmission / reception panel so as to receive the outside air supplied from the air supply duct, and is installed to distribute the outside air by distributing the high-pressure unit and the low- An upper duct for washing the internal components of the low pressure chamber; And a lower duct connected to the exhaust duct and connected to the exhaust duct to collect the air used for cleaning components installed in the special high-pressure unit, the variable-pressure unit and the low-pressure unit, and discharge the exhaust air to the exhaust duct. .

However, the above-mentioned "shielding type enclosed switchgear" has a problem that it is difficult to commercialize the duct because it is costly to install the duct while the air supply duct and the exhaust duct are used to block and discharge the harmful gas as much as possible there was.

The following inventions have been proposed in order to solve the cost problem due to the above-mentioned ducts. The following invention has been proposed, and Patent No. 10-0667047 entitled " Switchgear and automatic control panel structure for preventing the removal and inflow of moisture and corrosive noxious gas " Wherein the air circulation device is installed in the air inlet and the backflow prevention valve is installed in the inner air outlet, and the air circulation device is configured such that the outside air is blown by the fan, The inside air is opened only when the air pressure inside the control panel is higher than the atmospheric pressure by the check valve so that the air pressure inside the control panel is always higher than the atmospheric pressure of the outside or is kept at least equilibrium, Switchgear and automatic control panel to prevent harmful gas removal and inflow The present invention can prevent moisture, salinity, and corrosive noxious gas from flowing into the control panel from the outside by making the air pressure inside the control panel always higher than atmospheric pressure or at least maintaining equilibrium. , And air introduced into the inside can remove moisture and corrosive noxious gas by the air circulation device, so that the inside of the control panel is not dried and hot, and the removal of moisture and corrosive noxious gas which can maintain a clean state without harmful gas And a switchboard and an automatic control panel structure to prevent inflow.

However, in the case of the above-described "structure of a switchboard and an automatic control panel for preventing the removal and inflow of moisture and corrosive noxious gas ", it is assumed that the enclosure is completely closed. Generally, even if the switchboard is made of a closed type, There is a problem in that it is difficult to maintain the completely closed state due to the gap created for the wiring, and it is difficult to continue the closed state because the switchgear is opened and closed.
