Description

A system that efficiently supplies power to apartment houses {Efficient Power supply system for Apartment house}

The present invention relates to a system for efficiently supplying power to an apartment complex, and more specifically, to a power supply system that distributes power more efficiently in an apartment complex using an energy storage system (ESS). will be.

Energy Storage System (ESS) is a system that stores and manages energy that is difficult to store and disappears after use so that it can be used efficiently.

This ESS is undoubtedly an efficient system that stores surplus power, such as solar energy, during times of high power consumption and supplies it when needed.

However, in the case of apartment complexes, it is difficult to supply electricity to each household at a low price because the power consumption is different for each household. That is, some households can use 340 kWh, others can use 500 kWh, and still others can use 150 kWh. Among these, households that used 500 kWh may have to pay huge electricity bills due to the progressive rate system.

However, even if ESS is equipped, there is a problem in that it cannot efficiently supply power only to households affected by excessive electricity bills. Therefore, it is necessary to actively utilize ESS to supply power from ESS to households that use excessive amounts of electricity, thereby preventing major damage caused by the application of progressive rates.

Figure 1 is an overall configuration diagram showing a system that efficiently supplies power to the apartment complex 20 of the present invention.

In Figure 1, an energy storage system (ESS) 10 serves to store and manage energy and supply it to an apartment complex 20. The ESS is preferably located on or near the rooftop of an apartment building (20). Apartment complex (20) refers to a house where household units that consume electricity individually, such as multi-family houses or apartments, are gathered together.

Meanwhile, the transfer device 100 can selectively supply power from the energy storage system 10 to specific households in the apartment complex 20. In other words, power can be drawn from ESS and supplied intensively to only specific households.

Through this switching device 100, if a specific household consumes too much electricity, it is possible to prevent being hit with a bomb on electricity usage due to the application of a progressive tax, and it allows a specific household that has received electricity from the ESS to compensate later at a low price. . A more specific and detailed explanation will be provided later.

Meanwhile, it is preferable that the control unit 30 controls the switching device 100 to switch. Transfer can mean switching and means reallocating power wiring to specific households.

Meanwhile, the user terminal 50 is preferably provided with power consumption information for each household from the provider server 40 that supplies power, and transmits a control command to the control unit 30.

The user terminal 50 can be a terminal capable of wired or wireless communication, such as a smartphone or personal computer, and the provider server 40 refers to a server that holds data used for operation and billing by a business that supplies power. Therefore, the provider server 40 can hold data on the power consumption of each household in the apartment complex 20 and further transmit the data to the user terminal 50.

Figure 2 is a longitudinal cross-sectional view of the switching device 100 that constitutes a system that efficiently supplies power to the apartment complex 20 of the present invention.

As shown in FIG. 2, the switching device 100 largely includes a magnet case 110, a fluid cylinder 120, a coil case 130, a coil core 132, a coil 131, a rotating core 160, and a spring. It consists of (164), brush (150) and distribution drum (170).

First, the magnet case 110 is cylindrical, one end is closed, and the other end is sealed by a cover 111. And a circular bar magnet (113) is inserted inside it.

Additionally, the fluid cylinder 120 is attached to one end of the magnet case 110 on the outside and the MR fluid 121 is introduced into the magnet case 110. It is best to fill the MR fluid 121 with empty space rather than filling the inside of the fluid cylinder 120 completely.

That is, when the internal volume of the fluid cylinder 120 increases and the MR fluid 121 solidifies, there should be no change in the internal volume due to the elastic force of the spring 164 despite the presence of empty space, and the MR fluid 121 This is to ensure that the internal volume is sufficiently small when liquefied.

Here, the characteristic of the MR (Magneto-rheological Fluid) fluid is that it can be solidified by magnetic force lines, and in the present invention, solidification can be achieved by applying strong magnetic force lines by the coil 131 current.

Meanwhile, in FIG. 2, a head 133 reciprocating the inner peripheral surface of the fluid cylinder 120 and a coil case 130 and coil core 132 extending from the head 133 are shown. In addition, the coil 131 is wound between the coil case 130 and the coil core 132, and current flows in and out from the outside, and its surface is preferably insulated. Insulation prevents leakage current.

Additionally, the rotating core 160 accommodates a ring bearing 190 that rotates in contact with the end of the coil case 130. Even if the coil case 130 is fixed by the ring bearing 190, the rotating core 160 can rotate freely by gearing with the step motor 140.

Meanwhile, a core gear 142 is formed on the outer peripheral surface of the rotating core 160, which rotates in engagement with the motor gear 141 of the step motor 140.

Additionally, a guide shaft 163 protrudes from the center of the end of the rotating core 160, and an electrode ball 162 protrudes from the end of the outer circumferential surface of the rotating core 160 by elasticity or can easily be moved into the inside.

Figure 2 shows that the rotating core 160 moves to the right due to the repulsive force of the circular bar magnet 113 and the electrode ball 162 comes into electrical contact with the electrode piece 172. This repulsive force is due to the current being applied to the coil 131 to generate magnetic force lines. It is best to set the winding direction of the coil 131 so that the circular bar magnet 113 and the head 133 generate mutual repulsion according to Ampere's right-hand screw law.

Additionally, the repulsive force is strong enough to overcome the elastic force of the spring 164 fitted to the guide shaft 163, so the guide shaft 163 can be inserted into the guide groove 171. Accordingly, the spring 164 contracts. The elastic force of the spring 164 cannot move the head 133 in the direction of the magnet case 110 due to solidification of the MR fluid 121.

Meanwhile, the brush 150 electrically contacts the outer peripheral surface of the rotatable rotation core 160 and is electrically connected to the ESS supply line 151 that supplies power from the external ESS 10.

3 and 4 are longitudinal cross-sectional views and perspective views showing the distribution drum 170 of the switching device 100, which constitutes a system for efficiently supplying power to the apartment complex 20 of the present invention.

As shown in Figures 3 and 4, a guide groove 171 is formed at the center of the cylindrical distribution drum 170 so that the guide shaft 163 contacts the inner peripheral surface and reciprocates. And, on the open inner peripheral surface of the distribution drum 170, a plurality of electrode grooves 175 with a trapezoidal cross-section are formed in the longitudinal direction, and at the ends of the electrode grooves 175, there is an insertion hole leading to the electrode hole 173 connected to the outer peripheral surface ( 176) is formed.

Furthermore, the electrode piece 172 is inserted into the electrode groove 175, and the bottom is inserted into the fitting hole 176, so that the electrode pin is electrically connected to the distribution line 180 supplied to each household of the apartment complex 20. (174) protrudes.

In particular, in Figure 4, there are a total of four electrode grooves 175, so that power from the ESS can be individually supplied to four households, but it is obvious to those skilled in the art that the number can be increased to as many as necessary. .

Figure 5 is a partial enlarged view showing the electrode ball 162 that constitutes a system for efficiently supplying power to the apartment complex 20 of the present invention.

As shown in FIG. 5, the electrode ball 162 is inserted after the leaf spring 165 is inserted into the ball groove 167 formed at the end of the outer peripheral surface of the rotating core 160 and is inserted by the fixing ring 166 and the fastening pin 168. It is fixed so that it does not fall out. Accordingly, the electrode ball 162 enters the inside of the ball groove 167 due to external force, and protrudes due to elastic force when there is no external force.

Meanwhile, in FIG. 1, the control unit 30 may include a power supply unit 31 that supplies current to the coil 131 and a motor control unit 33 that controls the rotation angle of the step motor 140.

In addition, the user terminal 50 adjusts the angle of the step motor 140 through the control unit 30 to supply power of the energy storage system 10 to the household recording the maximum power consumption among the plurality of households in the apartment complex 20. A control command that performs an automatic mode that transmits a control command to adjust or adjusts the angle of the step motor 140 through the control unit 30 so that the user selects a specific furniture and supplies power to the energy storage system 10. It is better to perform manual mode to transmit.

Figure 6 is an assembled perspective view of the switching device 100 that constitutes a system that efficiently supplies power to the apartment complex 20 of the present invention.

Figure 7 is a longitudinal cross-sectional view showing that the guide shaft 163 of the switching device 100, which constitutes a system for efficiently supplying power to the apartment complex 20 of the present invention, is completely inserted into the guide groove 171 by repulsive force. am.

As shown in FIG. 7, the electrode ball 162 can enter into deep contact with the electrode piece 172. At this time, the MR fluid 121 is solidified, so the head 133 does not move again in the direction of the magnet case 110. Therefore, after the electrode ball 162 contacts the electrode piece 172, the power supplied from the ESS can be stably and continuously supplied to a specific household.

Figure 8 shows that the guide shaft 163 of the switching device 100, which constitutes a system for efficiently supplying power to the apartment complex 20 of the present invention, is pulled out from the guide groove 171 by the elastic force of the spring 164. This is a longitudinal cross-sectional view showing the electrode ball 162 being electrically separated from the electrode piece 172.

As shown in FIG. 8, when the current is blocked in the coil 131, the magnetic force lines are weakened and the MR fluid 121 is liquefied. Accordingly, the head 133 moves to the left due to the elastic force of the spring 164, and the electrode ball 162 is electrically separated from the electrode piece 172. This becomes an open circuit and power from the ESS is no longer supplied to specific households.

Looking at the overall characteristics of the present invention, when power is supplied from the energy storage system 10 to the furniture through the user terminal 50, the power supply unit 31 supplies current to the coil 131 and the head 133 and The electrode ball 162 is inserted into the distribution drum 170 by the repulsive force between the circular bar magnets 113, and the motor control unit 33 attaches the electrode ball 162 to the electrode piece 172 electrically connected to the specific furniture. Rotate to make contact, the MR fluid 121 is solidified by the magnetic force lines and the position of the electrode ball 162 is fixed, and when the power supply unit 31 blocks the current to the coil 131, the MR fluid 121 is liquefied and the spring The electrode ball 162 is separated from the electrode piece 172 by the elasticity of 164.

In addition, by rotating the electrode ball 162 at a precise angle using the step motor 140, the electrode ball 162 is controlled to accurately electrically contact a specific electrode piece 172 among the plurality of electrode pieces 172. This makes it possible to supply ESS power to specific households.
