Description

Planar coil for reactor and reactor having the same {Planar coil for reactor and reactor having the same}

The present invention relates to a reactor, and more particularly, to a flat plate coil in which a thin and wide plate-shaped material is wound from the outside to the inside two or more times, and a plurality of the plate-shaped coils are stacked and electrically connected. It relates to a flat-type coil for a reactor that is manufactured by disposing a cooler around the flat-type coils, so that the number of stacked flat-type coils is reduced in proportion to the number of windings, thereby enabling miniaturization, and a reactor having the same.

In general, reactors are used for various purposes. Representative reactors include a series reactor that is connected in series to a motor circuit to limit the current during a short circuit, a parallel reactor that stabilizes the current sharing between parallel circuits, and a current limiting current that protects machines connected to it by limiting the current during a short circuit ( Reactor, a starting reactor connected in series to the motor circuit to limit the starting current, a shunt reactor connected in parallel to the transmission line to compensate for phase-leading reactive power or suppress abnormal voltage, and a neutral point and A neutral point reactor connected between grounds and used to limit the ground fault current that flows in case of a ground fault in a power system, and an arc extinguishing reactor that automatically extinguishes the arc generated in the event of a one-line ground fault in a three-phase power system. there is.

Such a reactor provides a large inductive reactance to an alternating current or a sudden change in current by accumulation of electromagnetic energy, and may often have a structure in which a coil is wound around an iron core. At this time, the existing shape of the coil may be a winding type in which the material of the round bar is wound from top to bottom.

In the case of a reactor having such a wound coil, in order to increase the magnetomotive force, the number of windings is further increased, and the size is inevitably increased by that much.

In view of this, Korean Patent Registration No. 10-1948480 (title of invention: ferromagnetic magnetic magnetic reactor device and manufacturing method thereof), as shown in FIG. A ferromagnetic material (3) is inserted into the empty space of the winding part (2), and the ferromagnetic material (3) is extended to surround the winding part (2) to form a magnetic path (4); and, the winding part (2) A support unit (not shown) for applying pressure to the uppermost and lowermost ends of each plate-shaped material 1 so that they are electrically contacted through a connection unit; has been proposed as a reactor. Here, the plate-shaped material 1 has a substantially 'c' shape.

In the case of a reactor having such a winding part 2, compared to a reactor having a wound coil, the size can be reduced based on the same large current, the space factor is improved, and the magnetomotive force per unit area can be increased.

However, in order to make the size of the reactor smaller, the development of technology for making the size of the winding unit 2 smaller is also required.

Due to this shape, the connection part 41 at the outermost end, the outermost left longitudinal side 42, the outermost lower side 43, the outermost right side 44, the outermost upper side 45, and the outer left side A vertical side 46, a lower side road side outside the vehicle 47, a right side road side outside the vehicle 48, and an innermost side road side 49 may be provided.

Here, the connection part 41 is located inward by a certain length from the end so that it is connected on the same line with the other connection part 21 without being located on the same line as the connection terminal 11 in the form of stacking coils as in the lower part of FIG. It can be. Referring to FIG. 2, it may be positioned to the right by a certain length from the left end. In addition, as shown in FIG. 5 , the connection part 41 protrudes outward from the outermost shopping street side 45 for electrical connection of the connection parts 21 and may have the same or different width as the outermost left vertical side 42 .

Also, the width of the innermost shopping street 49 may be smaller than that of the outermost left longitudinal side 42 . For example, the innermost side street side 49 may have a width of 6 mm, a thickness of 0.7 mm, and a cross-sectional area of 4.2 mm ² . Here, since the innermost shopping street 49 is electrically connected to the innermost shopping street 19 having the same cross-sectional area in the (a) type flat coil 10 stacked below, as shown in FIG. 7, the innermost shopping roadside ( 49) and the innermost shopping street 19, the allowable design current can be approximately 50A. In addition, the width may be 5.7 to 6.3 mm, and the thickness may be 9.7 to 9.9 mm. And, the width of the outermost upper side 15 may be wider than the widths of the other sides in order to match the overall size of the (B) type flat coil 20 and the (C) type flat coil 40 .

On the other hand, as another example, as shown in FIG. 3, the (A) type 10, (B) type 20, and (C) type 40 flat plate coils C may be manufactured in a three-fold structure.

In particular, the width of the outermost shopping street, the width of the innermost shopping street, and other widths may also be the same as or proportionally thinner than that of FIG. 2 .

In addition, in the case of the three-time-wound flat coil C, compared to the two-time winding shape of FIG. 2 , intermediate sides may be further provided while additionally winding one time between the outer sides and the innermost side. Of course, the number of intermediate sides may also increase in proportion to the number of turns of the coil.

On the other hand, ballast water generally filled in a ship can help ensure safe navigation by minimizing the change in the center of gravity of the ship due to loading and unloading of cargo. That is, when a ship is loaded with heavy or light cargo, it is possible to safely navigate the ship by filling the ship with appropriate ballast water so that the center of gravity of the ship is located below the sea level.

Since the ballast water is filled or discharged in different areas while sailing, various marine organisms or pathogens in one area may be transported to another area, and the environment and ecosystem between the areas may be disturbed. Therefore, there is a demand for water treatment to sterilize marine organisms and pathogens when filling or discharging ballast water.

As such, a reactor equipped with a flat coil (C) of a structure wound two or more times according to the invention can be used in a facility for treating ballast water (commonly referred to as BWTS: Ballast Water Treatment System or BWMS: Ballast Water Management System). can
