Description

Leakage current blocking system

The present invention relates to a leakage current blocking system. More specifically, when leakage current occurs due to flooding or inflow of foreign substances, the leakage current can be recycled so that the operation of electronic equipment in use is maintained smoothly and leakage current is prevented. This relates to a leakage current blocking system that prevents electric shock and fire accidents caused by electric current.

Electric shock is a phenomenon in which the human body reacts when the leakage current flowing from the power source through the human body to the ground plane is above a certain level.

In general, if leakage current exceeds 15mA, convulsions occur, and if leakage current exceeds 50mA, death occurs.

The leading cause of death is heart attack, in which the heart stops working as the electrical current flowing through it damages the nerves.

The risk of electric shock is related to the resistance of the human body at the time of energization, which greatly depends on the condition of the skin.

When electrical equipment, such as an outlet, heater, or light, is submerged in water and the human body comes in contact with the water or a metal housing energized through water, the exposed conductor of the electrical equipment passes through the water and the human body, and becomes the ground plane. Electric current flows through the ground.

At this time, the human body's skin is likely to be wet with water, and in this case, the contact resistance is extremely low, so it becomes a very dangerous state.

A short circuit between power lines is a problem that occurs when the insulation between the two lines decreases and electrical conductivity increases, causing a rapid flow of current, causing equipment damage such as fire or short circuit in electrical equipment.

In general, the insulation of air is very high, and electrical insulation is maintained between two wires through air.

However, if fluid with high electrical conductivity fills the space between the two lines due to flooding, etc., the current between the phases increases rapidly, causing a short circuit.

Republic of Korea Patent Publication No. 2005-0037986 is a submersion electric shock prevention device that attaches a metal plate or metal mesh to an uncharged part and prevents electric shock accidents by attaching a metal plate or metal net to the uncharged part so that when it is submerged, the current leaking from the uncharged part passes through the conductive metal plate or metal net. is starting.

The metal plate or metal mesh is connected to the neutral and ground terminals of the terminal blocks by wires, and the size of the metal plate is approximately 50cm x 30cm.

The above prior art does not explain the principle in detail, but by arranging a metal plate in a state where the resistance is much lower than the resistance through water and the human body between the submerged conductors during submersion, and electrically forming it in parallel with the human body, It can be seen as limiting the current flowing through.

However, such a metal plate or metal mesh cannot effectively block leakage current because it cannot shield the electric field generated radially from the bare charging part, and there is a problem in that space restrictions occur in installation.

In addition, if the generated leakage current cannot be effectively blocked, the circuit breaker operates to cut off all current, and not only the leakage current but also all current flows are blocked, causing all electronic equipment in use to stop operating. There is a problem of not only safety accidents due to leakage current, but also secondary damage due to forced shutdown of electronic equipment.

Therefore, a method to solve these problems is required.

Hereinafter, preferred embodiments of the present invention in which the object of the present invention can be realized in detail will be described with reference to the attached drawings. In describing this embodiment, the same names and the same symbols are used for the same components, and additional description accordingly will be omitted.

The present invention makes it possible to recycle the leakage current when leakage current occurs due to waterlogging or inflow of foreign substances, so that the operation of electronic equipment in use can be maintained smoothly and electric shock and fire accidents due to leakage current can be prevented. It is about a leakage current blocking system.

This leakage current blocking system connects a connection part (C) to which electronic equipment can be connected and a distribution part (B) connected to the connection part (C), and a first wire that can play the role of a neutral line and a phase power line. (100) and the second wire 200, the auxiliary grounding part (BG) that may be provided in the connection part (C), and the main grounding part (MG) that may be provided in the distribution part (B) may be interconnected. A ground wire 300, one side of which is connected to one side of the first wire 100, and the other side of which is connected to one side of the ground wire 300, so that the first wire 100 and the ground wire 300 are connected. The first connection line 400 and one side are connected to one side of the second electric wire 200, and the other side is connected to one side of the ground wire 300, so that the second electric wire 200 and the ground wire 300 It may include a second connection line 500 that allows this connection.

Here, the distribution unit (B) can be interpreted as an outlet, a distribution box, or a switchboard provided on a wall or pillar, and the connection unit (C) is connected to the distribution unit (B) on one side and is used on the other side. It can be interpreted as one or more outlets (consent) into which a plug provided in the desired electronic equipment is inserted, for example, a portable outlet such as a multiple-tap.

The leakage current blocking system of the present invention as described above is designed to connect the connection part (C) along the ground wire 300 when leakage current is generated due to water immersion or inflow of foreign substances, etc. in the connection part (C) where the electronic equipment to be used is connected. A leakage current flows from the auxiliary grounding part (BG) provided in the main grounding part (MG) provided in the distribution part (B), and the leakage current flowing along the grounding line 300 is connected to the grounding line 300. ) flows into the first wire 100 and the second wire 200, which play the role of a neutral wire and a phase power line, through the first connection line 400 and the second connection line 500, which are connected to the current. Accordingly, it can be recycled as the power needed to drive the electronic equipment.

At this time, most of the leakage current may flow into the first wire 100 and the second wire 200 through the first connection line 400 and the second connection line 500, as described above. Only a very small amount of leakage current remaining after flowing into the wire 100 and the second wire 200 can be moved to the main ground part MG through the ground wire 300 and discharged safely.

For example, depending on the direction of the inserted plug, if the first wire 100 functions as a phase power line and the second wire 200 functions as a neutral wire, the flow of current flows through the first wire. It moves from the distribution unit (B) to the connection unit (C) along (100), and the current passing through the connection unit (C) moves back to the distribution unit (B) through the second wire 200. do.

At this time, the leakage current generated in the connection part (C) flows from the auxiliary ground part (BG) to the main ground part (MG) through the ground line 300, and some of this leakage current flows through the first connection line. flows into the first wire 100 through 400, and the remaining leakage current flows into the second wire 200 through the second connection line 500, thereby allowing the electronic equipment to be driven. By allowing the electric current to move naturally according to the flow of current from the electric wire 100 to the second electric wire 200, the leakage current can be recycled as current necessary for driving electronic equipment.

And, among the leakage current flowing along the ground line 300, only a very small amount of leakage current, excluding the leakage current recycled through the first connection line 400 and the second connection line 500, is discharged through the main ground portion (MG). By doing so, it is possible to prevent electric shock accidents from occurring due to leakage current.

At this time, when the amount of leakage current generated from the connection part (C) is small, the leakage current discharged through the main ground part (MG) can be converged to 0, which means that the amount of leakage current generated is This means that even if the leakage current can be recycled through the first connection line 400 and the second connection line 500, the leakage current can be safely discharged through the main ground portion (MG) only if the leakage current remains. This can be expected to significantly reduce the risk of electric shock and fire due to leakage current.

In addition, as leakage current is effectively recycled in this way, even if leakage current occurs, the circuit breaker that may be provided in the distribution unit (B) does not fall, so that the operation of the electronic equipment in use can be maintained smoothly. This means that the primary blocking of the leakage current is ensured before the circuit breaker is activated. If the amount of recycled leakage current rapidly exceeds the amount of leakage current due to excessive leakage current, the circuit breaker operates secondarily. As a result, it can be understood as meaning that safety can be double secured in preparation for leakage current.

According to an embodiment of the present invention, when a leakage current is generated by connecting the auxiliary ground part (BG) provided in the connection part (C) and the main ground part (MG) provided in the distribution part (B), , the ground line 300, which serves as an discharge rod for leakage current, allows the leakage current generated in the connection part (C) to flow from the auxiliary ground part (BG) to the main ground part (MG) along the ground line 300. It may further include a diode member (D) that limits the flow of leakage current in one direction so that it can flow smoothly, can be connected to the diode member (D), and assists the diode member (D) with the ground wire ( 300) may further include a resistance member (R) that limits the direction of leakage current flowing in one direction.

For example, the diode member (D) can be provided on one side of the ground line 300 so that the leakage current flowing along the ground line 300 can be maintained in one direction, and a more stable one-way current flow can be achieved. The resistance member (R), which can assist the diode member (D), is further provided on one side of the ground wire 300 to ensure that the current flowing in a direction with a small degree of obstruction (resistance) to the flow. Depending on the characteristics, the reverse current does not occur, so the risk of short circuit can be prevented in advance.

In addition, when leakage current occurs in the ground wire 300, it consumes the leakage current flowing along the ground wire 300 and at the same time lights up a specific color, for example, red, so that the user can visually determine the presence or absence of leakage current. It may further include a first light emitting body 600 that emits light.

*For example, the first light emitter 600 is provided on one side of the ground line 300 and emits light as a specific light by the leakage current flowing along the ground line 300, thereby consuming the leakage current and user It is possible to directly recognize the presence or absence of leakage current.

This first luminous body 600 can be linked with the alarm member 900, which will be described later, so that when leakage current occurs, the first luminous body 600 emits light and at the same time, the alarm member 900 emits an alarm sound. By allowing this to occur, the user can visually and audibly check the occurrence of leakage current, allowing for a clearer perception.

According to one embodiment of the present invention, on one side of the first connection line 400 and the second connection line 500, a diode member (D) is provided to limit the flow of leakage current in one direction, similar to the ground line 300. ) may be further provided.

For example, the first connection line 400 and the second connection line 500 are provided with the diode member (D) so that the flow direction of the leakage current can be fixed to the first wire 100 and the second wire 200, respectively. may be provided, and a leakage current is generated by the diode member (D), so that the leakage current flowing along the ground line 300 is connected to the first connection line 400 and the second connection line 500. It ensures smooth flow toward the electric wire 100 and the second electric wire 200, and at the same time, the first connection line 400 and the second connection line 500 are connected from the first electric wire 100 and the second electric wire 200. By preventing current from flowing into the ground wire 300, recycling of leakage current can be smoothly achieved and occurrence of short circuit can be prevented.

At this time, it is recognized that in some cases, the first connection line 400 and the second connection line 500 may be further provided with the resistance member (R) along with the diode member (D) in the same way as the ground line 300. shall.

According to one embodiment of the present invention, the leakage current blocking system according to the present invention may further include an alarm member 900 as mentioned above.

As shown in FIG. 3, one side of the alarm member 900 is connected to one side of the ground wire 300, and the other side is connected to the first wire 100 or the second wire 200 to prevent leakage current. When generated, it is driven by the flow of current to generate an alarm sound, thereby allowing the user to auditorily recognize the presence or absence of leakage current.

At this time, the current flows in one direction between the ground wire 300 on which the alarm member 900 is provided and the first wire 100 or between the ground wire 300 and the second wire 200. By further providing a limiting diode member (D), the leakage current flowing along the ground line 300 moves toward the first wire 100 or the second wire 200 to drive the alarm member 900. It is desirable to prevent current from flowing into the ground wire 300 from the first wire 100 and the second wire 200, thereby preventing the occurrence of a short circuit.

In addition, the alarm member 900 may consist of a single alarm sound, but is not limited to this. Depending on the amount of leakage current flowing along the ground line 300, the sound of the alarm sound increases step by step or a different alarm sound is heard. By setting this to occur, an emergency situation due to leakage current can be more clearly recognized by the user.

In addition, the leakage current blocking system according to the present invention may further include a communication member (E) that allows the warning member 900 to be activated and a warning signal to be transmitted to the user's mobile device when leakage current occurs. You can.

In addition, the leakage current blocking system according to the present invention can be installed in a location desired by the user, spaced apart from the distribution part (B) and the connection part (C), and can be connected to the communication member (E), so that when leakage current occurs, It may further include an alarm generator (W) capable of receiving a signal from the communication member (E) and emitting light and/or generating an alarm sound.

In this way, it is connected to the communication member (E) and the communication member (E) so that a warning signal can be transmitted to the user's mobile device, and is installed in a location desired by the user to emit light and/or alarm when leakage current occurs. The alarm generator (W), which generates a sound, allows the user to immediately check the occurrence of leakage current and take an appropriate response even if the user has gone out or is away from the site where the leakage current occurred. , not only can the user's safety be guaranteed, but it can also prevent electric shock or fire.

In addition, the leakage current blocking system according to the present invention is further equipped with a temperature measuring unit (T) that can measure in real time the temperature change inside the connection part (C) due to the occurrence of leakage current when leakage current occurs. The temperature measuring part (T) may be composed of a temperature measuring sensor and a heat detection sensor provided inside or on one side of the connecting part (C).

In addition, it is possible to connect with the temperature measuring unit (T) wirelessly or by wire, so that the user can determine the temperature change of the connecting unit (C) in real time by receiving the information measured by the temperature measuring unit (T). By further providing a temperature indicating member (TS) that can visually indicate changes in temperature, the user can continuously check the real-time temperature of the connection part (C) and recognize the presence or absence of leakage current.

In addition, the leakage current blocking system according to the present invention may further include a display member (S) that can display the amount of leaked current so that the user can recognize it when leakage current occurs.

The display member (S) can numerically display the amount of leakage current moving along the ground line 300, but is not limited to this, and the amount of leakage current can be measured using one standard. By setting it in stages, the gauge fills or emits light sequentially depending on the amount of leaked current, allowing the user to easily recognize the level of risk depending on the amount of leaked current.

At this time, the display member (S) can be connected to the alarm member (900), and if a leakage current is generated through the connection between the display member (S) and the alarm member (900), the An alarm sound can be generated from the alarm member 900. In this case, when the display member S is set in stages based on the amount of leakage current, the alarm sound generated from the alarm member 900 is also similar to the alarm sound. It is possible to make the alarm sound louder sequentially in response to each stage, or to generate different alarm sounds for each stage so that the user can easily recognize the risk of leakage current generated according to the alarm sound.

At this time, a diode member (D) is provided on one side of the third connection line 800 to limit the direction of the current flowing along the third connection line 800 to one direction, so that the first wire 100 ) and the second wire 200 can prevent a short circuit from occurring due to a short circuit.
