Description

Water distribution facility equipped with air conditioning unit

The present invention relates to a water distribution facility, and more particularly, to a water distribution facility equipped with an air conditioning unit that blocks harmful air flowing into the power distribution facility.

In general, the power distribution facility receives a voltage ranging from high to low voltage, step down to commercial voltage, and distributes it to each part of a building, a motor control panel that protects the three-phase motor by controlling the three-phase motor, and from the main line during indoor wiring. Includes distribution boards, etc. that are installed in places where each branch circuit is divided.

In general, it is impossible to receive electricity that can be used directly from a power company, such as a general electric facility of 110V or 220V, because the amount of power demand is high in private electric facilities such as mines and factories. Therefore, in general private electric equipment, a high-voltage voltage of 3,300V or 6,600V must be received from the distribution line of a substation and converted back to a commercial voltage. The device that enables this is a switchboard.

The switchboard is a power receiving unit for receiving high-voltage and special high-voltage electricity supplied from a substation, a substation for stepping down the high-voltage and special high-voltage electricity received from the substation to a commercial voltage, and the stepped down electricity to electronic equipment and lighting facilities. Includes electrical equipment such as distribution units and other safety devices for supply in the interior space.

Such switchgear is operated and maintained in a state where the internal space is cut off from the outside in order to protect various electric devices installed inside. However, inside the switchgear, harmful substances such as fine dust, moisture, and bacteria introduced from the outside are fused to the surface of the enclosure inside the electrical device or switchboard, causing a breakdown of the electrical device or a fire due to the tracking phenomenon. In order to solve this problem, a ventilation structure is installed inside the switchgear to circulate external air and internal air to purify the internal air of the switchgear.

However, in the case of purifying the internal air using the ventilation structure installed inside the switchgear, the internal air including harmful substances is fused to the electrical equipment and the surface of the enclosure inside the switchboard during the process of being purified by the ventilation structure, and the fused harmful substances are not purified. There is a problem that the filter needs to be replaced frequently if the filter is contaminated while the air is purified by the dust collection filter.
