Abstract

The present invention relates to a power distribution facility and, more particularly to power distribution facility including an inertial filter unit to block harmful substances in air introduced into the power distribution facility. It is an objective of the present invention to block introduction of harmful substances by separating the harmful substances from external air introduced into the power distribution facility in order to solve the above problem. The present invention may separate the harmful substances from external air introduced in a body through an inertial filter unit included in a position corresponding to a position of an inlet at one side of an enclosure before the external air included in the harmful substances is introduced into the enclosure to block introduction of the harmful substances in an inner space of the enclosure. Further, since the present invention receives the harmful substances separated by the inertial filter unit in a receiving box, an additional fee due to replacement of a separate inertial filter unit is not consumed so that economic efficiency may be increased. Moreover, since the present invention separates harmful substances from the external air introduced into the inertial filter unit by principles of inertia and collision through an inertial filter, the inertial filter unit is not physically consumed but can be permanently used so that a management cost may be reduced. In addition, since air flow is adjusted by controlling a spacing distance between inertial filters, pressure loss is reduced so that energy consumption according to power consumption may be increased. Furthermore, the harmful substances may be easily collected and wasted by attaching and detaching a receiving box for receiving the harmful substances so that consumption costs for processing a waste may be reduced.

Description

Water distribution system equipped with inertial filter unit {POWER SUBSTATION WITH INERTIAL FILTER UNIT}

The present invention relates to a water distribution facility, and more particularly, to a water distribution facility provided with an inertial filter unit that blocks harmful substances in the air flowing into the water distribution facility.

In general, the water distribution equipment receives voltage from high voltage to low voltage to step down to a commercial voltage and distribute it to each part of the building, and a motor control panel that protects a three-phase motor by controlling a three-phase motor, and from main lines during indoor wiring. It includes a distribution panel installed in a place where each branch circuit splits.

In general, in a private electric facility such as a mine or factory, it is impossible to receive electricity that can be used as it is from a power company, such as a 110V or 220V low voltage general electric facility. Therefore, in a general private electric facility, a high voltage voltage of 3,300V or 6,600V is received from a distribution line of a substation and the voltage must be transformed back to a commercial voltage. An apparatus that enables this is a switchgear.

The switchboard includes a power receiving unit for receiving high-voltage and special high-voltage electricity supplied from a substation, a substation for powering down high-voltage and special high-voltage electricity received from a substation to a commercial voltage, and using the pressed electricity as electronic equipment and lighting facilities. Electrical equipment such as power distribution and other safety devices for supply are included in the interior space.

In order to protect various electric devices installed therein, the switchboard is operated and maintained with the internal space blocked from the outside. However, inside the water switchboard, harmful substances such as fine dust, moisture, and bacteria from outside are fused to the surface of the inside of the electric device or the inside of the switchgear, causing a malfunction or fire due to tracking. In order to solve this problem, the development of a water distribution panel having a ventilation structure for purifying the internal air of the water distribution panel by circulating the external air and the internal air by installing a ventilation structure inside the water distribution panel has been made.

However, in the case of purifying the internal air by using the ventilation structure installed inside the water switchboard, in the process of the internal air containing harmful substances being purged by the ventilation structure, it is fused to the surface of the electrical equipment and the enclosure inside the water switchboard, and the fused harmful substances are not purified. There is a problem that does not exist, and if the filter is contaminated in the process where the air is purified by the dust collecting filter, there is a problem that the filter needs to be replaced frequently.
