Description
Technical Field
The present invention relates to a leakage current blocking system, and more particularly, to a leakage current blocking system capable of preventing an electric shock accident and a fire accident due to leakage current by smoothly maintaining driving of an electronic device in use by recycling the leakage current when the leakage current is generated due to flooding, an inflow object, or the like.
Background
The electric shock is a human body reaction phenomenon caused when a current flowing from a power supply to a ground surface as a ground plane through a human body reaches a certain value or more.
Normally, if the flowing leakage current is 15mA or more, twitching will be caused, and if it is 50mA or more, death will be caused.
The main cause of death is cardioplegia, where the flow of electricity through the heart damages nerves, causing the heart to stop.
The risk of electric shock is related to the current resistance of the human body, which is largely dependent on the skin condition.
For example, when an electrical device such as a socket, an electric heater, or an electric lamp is immersed in water, if a human body is in contact with water or a metal casing or the like energized by the water, electric current flows from a conductor exposed by the electrical device to a ground surface which is a ground plane through the water or the human body.
In this case, since the human skin is in a submerged state, it will be in a very dangerous state as the contact resistance becomes extremely low.
A short circuit between power supply lines is a problem in that if the electrical conductivity increases due to a decrease in the insulation strength between two lines, electrical equipment is damaged such as fire or short circuit due to rapid flow of current.
In general, the insulating strength of air is very high, and therefore, electrical insulation is maintained between two wires with air as a medium.
However, if a fluid having a high electrical conductivity is filled between the two wires due to flooding or the like, a short circuit is caused by a rapid increase in current therebetween.
For this reason, korean laid-open patent publication No. 2005-0037986 discloses a water-immersion electric shock prevention device in which a metal plate or a metal mesh is attached to a bare charging portion, and a current leaked from the bare charging portion is electrically connected to a conductive metal plate or metal mesh when immersed in water, thereby preventing an electric shock accident.
The metal plate or the metal mesh is connected to the neutral line and the ground terminal among the plurality of connection terminals through an electric wire, and the metal plate has a size of approximately 50cm×30cm.
The above-described conventional art, although not describing the principle in detail, may be considered as a principle that, in the case of immersion, a metal plate is disposed in such a manner that the electrical resistance between the immersed conductors is lower than the electrical resistance passing through water and the human body, and a parallel structure is implemented with the human body to limit the current flowing into the human body.
However, such a metal plate or metal mesh cannot shield an electric field generated radially in the bare cell, and thus cannot effectively block leakage current, and there is a limit in terms of installation space.
When the generated leakage current cannot be effectively blocked, the circuit breaker is started to block all the current, and the driving of the electronic equipment in use is stopped along with the blocking of all the leakage current and all the flowing of the current, so that not only the safety accident caused by the leakage current occurs, but also the secondary damage caused by the forced stopping of the electronic equipment is caused.
Accordingly, a method for solving the above-described problems is currently required.

Detailed Description
Hereinafter, preferred embodiments of the present invention which can embody the objects of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same names and the same reference numerals are used for the same structures, and thus, additional description thereof will be omitted.
The present invention relates to a leakage current blocking system capable of smoothly maintaining driving of an electronic device in use by recycling leakage current when leakage current is generated due to immersion or inflow of foreign matter, etc., and capable of preventing occurrence of electric shock accident and fire accident due to leakage current.
The leakage current blocking system may include: the first and second electric wires 100 and 200 connected between a connection part C connectable to an electronic device and a power distribution part B coupleable to the connection part C, and capable of performing functions of a neutral line and a phase power line; a ground line 300 for enabling the auxiliary ground BG, which can be provided at the connection portion C, to be connected to the main ground MG, which can be provided at the distribution portion B; a first connection wire 400 having one side connected to one side of the first wire 100 and the other side connected to one side of the ground wire 300, such that the first wire 100 can be connected to the ground wire 300; and a second connection wire 500 having one side connected to one side of the second wire 200 and the other side connected to one side of the ground wire 300, such that the second wire 200 may be connected to the ground wire 300.
The power distribution unit B may be interpreted as a receptacle (present) provided on a wall or a column, a distribution box or a distribution board, one side of the connection unit C may be connected to the power distribution unit B, and one or more receptacles (present) provided on the other side into which a plug (plug) of an electronic device to be used is inserted may be interpreted as a mobile receptacle such as a power strip (multiple-tap).
In the leakage current blocking system according to the present invention, when the connection portion C connected to the electronic device to be used is subject to leakage current due to flooding or inflow of foreign matter, the leakage current flows along the ground line 300 from the auxiliary ground portion BG provided at the connection portion C toward the main ground portion MG provided at the power distribution portion B, and the leakage current flowing along the ground line 300 flows into the first and second electric wires 100 and 200 functioning as neutral and phase power lines through the first and second connection lines 400 and 500 connected to the ground line 300, thereby being circulated to use electric power required for driving the electronic device by the flow of electric current.
In this case, as in the above-described manner, most of the leakage current can flow into the first and second electric wires 100 and 200 through the first and second connection lines 400 and 500, so that only a very small amount of the leakage current remaining after flowing into the first and second electric wires 100 and 200 can be moved to the main ground MG through the ground line 300 and safely discharged.
For example, when the first electric wire 100 is used as a phase power wire and the second electric wire 200 is used as a neutral wire according to the direction of the plug inserted, the flow of the current moves from the power distribution portion B to the connection portion C along the first electric wire 100, and the current passing through the connection portion C moves toward the wiring portion B again through the second electric wire 200.
In this case, the leakage current generated in the connection portion C flows from the auxiliary ground BG to the main ground MG through the ground line 300, and a part of the leakage current flows into the first electric wire 100 through the first connection line 400, and the remaining leakage current flows into the second electric wire 200 through the second connection line 500, so that the flow of current from the first electric wire 100 to the second electric wire 200 for driving the electronic device becomes natural, and the leakage current is recycled as the current required for driving the electronic device.
Further, among the leakage currents flowing along the ground line 300, only a very small amount of residual leakage current is discharged through the main ground MG, in addition to the leakage currents recycled through the first and second connection lines 400 and 500, thereby preventing an electric shock accident from occurring due to the leakage currents.
In this case, when the amount of leakage current generated at the connection portion C is small, the leakage current discharged through the main ground portion MG may be converged to 0, which means that, when the amount of generated leakage current is large, even though the leakage current may be recycled through the first connection line 400 and the second connection line 500, there is a surplus leakage current, in which case the leakage current is safely discharged through the main ground portion MG, and thus, an effect of greatly reducing the risk of electric shock and fire due to the generation of leakage current may be obtained.
Further, it is understood that even in the case where the leakage current is generated, the cyclic utilization of the leakage current can be effectively realized in the above manner to prevent the occurrence of the disconnection of the circuit breaker which can be provided in the above-described power distribution portion B, whereby the driving of the electronic device in use can be smoothly maintained, and this means that the first blocking of the leakage current is ensured before the circuit breaker is driven, and when the amount of the leakage current which is cyclically utilized has been greatly exceeded due to the excessive leakage current, the leakage current can be dealt with by the second operation of the circuit breaker, and the double safety can be ensured.
According to an embodiment of the present invention, the ground line 300 connects the auxiliary ground portion BG provided at the connection portion C with the main connection portion MG provided at the distribution portion B, and performs a function of a drain path of the leakage current in case of occurrence of the leakage current, and the ground line 300 may further include a diode member D for restricting the leakage current to flow in a direction so that the leakage current generated at the connection portion C smoothly flows from the auxiliary ground portion BG to the main ground portion MG side along the ground line 300, and the ground line 300 may further include a resistor member R capable of being coupled with the diode member D for assisting the diode member D to restrict the leakage current to flow in the direction of the ground line 300 to one direction.
For example, the diode member D may be provided at one side of the ground line 300 so that leakage current flowing along the ground line 300 may be maintained in one direction, and the resistor member R may be provided at one side of the ground line 300 so as to assist the diode member D, whereby the flow of current in one direction may be ensured to be more stable, and thus, the risk of occurrence of reverse running of current may be prevented based on the current characteristics flowing in a direction in which the degree of flow inhibition (resistance) is relatively small, thereby preventing the risk of a wire bonding in advance.
In addition, the contact ground 300 may further include a first light emitting body 600, and when a leakage current is generated, not only the leakage current flowing along the ground 300 is consumed, but also light of a specific color, for example, red or the like, is emitted at the same time, whereby a user can visually confirm whether the leakage current is generated.
For example, the first light emitting body 600 is disposed at one side of the ground line 300, and consumes the leakage current by emitting light of a specific color by the leakage current flowing along the ground line 300, and allows a user to directly confirm whether the leakage current is generated.
Such a first light emitting body 600 can be coupled to the alarm unit 900, which is described below, so that the first light emitting body 600 emits light when a leakage current is generated, and at the same time, an alarm sound can be generated from the alarm unit 900 so that a user can confirm the occurrence of the leakage current by visual/audible means at the same time, thereby making it possible to more clearly recognize the occurrence of the leakage current.
According to an embodiment of the present invention, as with the ground line 300, a diode member D may be provided on one side of the first and second connection lines 400 and 500, respectively, for limiting leakage current to flow in one direction.
For example, the diode member D is provided on the first and second connection lines 400 and 500, respectively, to fix the flow direction of the leakage current to the first and second wires 100 and 200, and in the case of occurrence of the leakage current, the diode member D allows the leakage current flowing along the ground wire 300 to smoothly flow to the first and second wires 100 and 200 through the first and second connection lines 400 and 500, and prevents the leakage current from flowing from the first and second wires 100 and 200 to the ground wire 300 through the first and second connection lines 400 and 500, thereby smoothly recycling the leakage current and preventing the occurrence of the wire.
In some cases, it should be understood that the diode member D and the resistor member R may be provided together in the first connection line 400 and the second connection line 500, as in the ground line 300.
As described above, according to an embodiment of the present invention, the leakage current blocking system of the present invention may further include the alarm part 900.
As shown in fig. 3, one side of the alarm part 900 is connected to one side of the ground wire 300, and the other side is connected to the first or second wire 100 or 200, and in case of leakage current, driving is performed by the flow of current and an alarm sound is generated, so that a user can recognize whether leakage current is generated or not through hearing.
In this case, a diode member D for restricting the current flow to one direction is further provided between the ground wire 300 and the first wire 100 or between the ground wire 300 and the second wire 200, in which the alarm member 900 is provided, and the alarm member 900 may be driven as the leakage current flowing along the ground wire 300 moves toward the first wire 100 or the second wire 200, and it is preferable that the occurrence of a wire is prevented in advance by preventing the current from flowing from the first wire 100 and the second wire 200 to the ground wire 300.
The alarm unit 900 may emit a single alarm sound, but is not limited thereto, and may emit alarm sounds of different volumes or different alarm sounds at each stage based on the amount of leakage current flowing along the ground line 300, so that a user can clearly recognize an emergency even when leakage current occurs.
In addition, in the case where the leakage current is generated, the leakage current blocking system of the present invention may further include a communication part E for transmitting a warning signal to the mobile device of the user while the alarm part 900 is operated.
The leakage current blocking system according to the present invention may further include an alarm generating unit W that is provided at a desired position of the user, spaced apart from the power distribution unit B and the connecting unit C, and that is coupled to the communication member E, and that receives a signal from the communication member E to emit light and/or sound an alarm when a leakage current occurs.
As described above, the communication means E transmits a warning signal to the mobile device of the user, and the alarm generating unit W coupled to the communication means is provided at a desired position of the user, and when a leakage current is generated, the alarm generating unit W can emit light and/or sound an alarm, so that even when the user goes out or is far from the site where the leakage occurs, it is possible to immediately confirm whether the leakage current is generated and respond appropriately, thereby not only ensuring the safety of the user, but also preventing the occurrence of an electric shock or fire.
The leakage current blocking system of the present invention may further include a temperature measuring unit T for detecting a temperature change in the connecting unit C caused by the occurrence of the leakage current in real time, wherein the temperature measuring unit T may be a temperature measuring sensor or a thermal sensor, and may be provided in the connecting unit C or at one side thereof.
The leakage current blocking system of the present invention may further include a temperature display unit TS connected to the temperature measuring unit T in a wireless or wired manner, and configured to visually display the received information measured by the temperature measuring unit T, so that a user can grasp a temperature change of the connecting unit C in real time, and thus, the user can recognize whether leakage current is generated by grasping the real-time temperature of the connecting unit C continuously.
Also, the leakage current blocking system of the present invention may further include a display part S for displaying the amount of current leaked in case of generating the leakage current so that the user can recognize.
As described above, the display unit S may display the amount of leakage current moving along the ground line 300 as a numerical value, but is not limited thereto, and the amount of leakage current may be set in stages according to one reference, whereby a standard scale (gauge) is gradually increased or light is emitted according to the amount of leakage current so that a user can easily recognize the degree of danger caused by the amount of leakage current.
In this case, the display unit S may be connected to the alarm unit 900, and in the case where a leakage current is generated, the alarm unit 900 may be caused to generate an alarm sound by the connection of the display unit S to the alarm unit 900, and in this case, in the case where the display unit S is set in each stage based on the amount of the leakage current, the alarm sound generated from the alarm unit 900 may correspond to each stage, and thus, in the case where the alarm sound is generated, the alarm sound of a different volume may be generated in each stage or a different alarm sound may be generated in each stage, and thus, the user may easily recognize the risk degree of the leakage current.
According to an embodiment of the present invention, the leakage current blocking system may further include a second light 700 for confirming whether the current flowing between the power distribution portion B and the connection portion C is normal.
For example, the leakage current blocking system may further include: a third connection wire 800 having one side connected to the first wire 100 and the other side connected to the second wire 200, such that the first wire 100 is connected to the second wire 200; and a second light emitting body 700 provided on the third connection line 800 and emitting light of a specific color, for example, green, so that a user can visually confirm whether or not the current flow between the power distribution portion B and the connection portion C is normal.
That is, the second light emitting body 700 operates by the current flowing through the first and second wires 100 and 200, which are connected between the power distribution unit B and the connection unit C and through which the current normally flows, so that a user can visually confirm whether the power distribution unit B and the connection unit C are normally driven.
In this case, a diode member D for restricting a current flowing along the third connection line 800 to one direction may be provided at one side of the third connection line 800, so that a short circuit may be prevented from being caused by a wire between the electric wire 100 and the second electric wire 200.
In some cases, as with the ground line 300, a resistor R may be provided in the third connection line 800, and may be coupled to a diode member D provided in the third connection line 800 to assist the diode member D in restricting the current flowing in the third connection line 800 to one direction more stably.
With the above configuration, the leakage current blocking system according to the present invention can make the first and second wires 100 and 200 each perform the function of a phase power line or a neutral line according to the direction in which the plug of the electronic device is inserted, and can recycle the current flowing through the first and second connection wires 400 and 500 as the current flows through the first and second wires 100 and 200 in consideration of the ac principle of the current as the power required for driving the electronic device is recycled when the leakage current is generated.
In addition, if the leakage current flowing along the ground line 300 exceeds the amount recycled through the first and second connection lines 400 and 500, the leakage current flowing along the ground line 300 is continuously consumed by the alarm member 900, the first light emitting body 600, and the resistor member R, and thus, not only is the blocking of the leakage current stably achieved, but also the leakage current can be effectively blocked before the circuit breaker of the power distribution unit B operates, and thus, it is possible to ensure that a user is protected from an electric shock risk and a fire risk by smoothly maintaining the driving of the electronic device, and also, it is not inconvenient to use the electronic device.
The leakage current blocking system of the present invention as described above is applicable not only to a switchboard in a large-sized place such as a factory but also to a general house, and particularly to a strip as a mobile outlet, and thus has very high availability.
Referring to the exemplary diagram of fig. 4, a power strip to which the leakage current blocking system of the present invention as described above is applied can be further easily understood.
While the preferred embodiments of the present invention have been described above, it will be apparent to those skilled in the art to which the present invention pertains that the present invention may be embodied in other embodiments than those described above without departing from the spirit or scope of the invention. The above-described embodiments are merely examples and are not intended to be limiting, and the present invention is not limited to the above description, but may be modified within the scope and equivalents of the scope of the invention as claimed.
