Description

Leakage Current Blocking Device

The present invention relates to a leakage current blocking device, and more particularly, when leakage current occurs due to flooding or inflow of foreign substances, the leakage current is effectively blocked to prevent the risk of electric shock or fire, and to ensure safe use of electronic products. It relates to a leakage current blocking device that makes it possible.

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, which is the ground plane, exceeds a certain value.

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

*The leading cause of death is heart failure, in which the heart stops working as the current flowing through the heart 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 electrical outlets, electric heaters, or lights are submerged in water and the human body contacts the water or a metal housing that is energized through the water, the exposed conductor of the electrical equipment passes through the water and the human body. current flows through the ground

At this time, the human body is in a very dangerous state because the skin is easily wet with water and in that case the contact resistance is extremely low.

A short circuit between power lines is a problem that causes damage to equipment such as fire or short circuit in electrical equipment by a rapid flow of current when the insulation level between the two lines is lowered and the electrical conductivity is increased.

In general, the insulation of air is very high, so air is used as a medium to maintain electrical insulation between two wires.

However, when a fluid with high electrical conductivity is filled between the two lines due to flooding or the like, the current between the phases increases rapidly, resulting in a short circuit.

Korean Patent Laid-open Publication No. 2005-0037986 discloses a device for preventing electric shock by attaching a metal plate or metal mesh to a bare charging part so that when flooded, current leaking from the bare charging part is energized through the conductive metal plate or metal mesh to prevent an electric shock accident. is starting

The metal plate or metal net is connected to the neutral wire and the ground terminal of the terminal blocks by wires, and the size of the metal plate is approximately 50 cm X 30 cm.

The above prior art does not explain the principle in detail, but it is electrically configured in parallel with the human body by placing a metal plate in a state in which the resistance is much lower than the resistance through water and the human body between the submerged conductors when submerged. It can be seen as limiting the current that flows.

However, such a metal plate or metal mesh does not effectively block a leakage current because it cannot shield an electric field radially generated from a bare charging unit, and there is a problem in that installation is limited in space.

Therefore, a method for solving these problems is required.

According to an embodiment of the present invention, in the first ground wire 600, the leakage current generated in the power distribution unit B is provided inside the leakage current blocking unit 100, the first coil member 140 A diode member (D) capable of limiting the flow direction of current to one direction to prevent current from flowing from the first coil member 140 to the power distribution unit (B) More may be provided.

For example, the leakage current generated in the power distribution unit (B) may be collected in the leakage current blocking unit 100 through the first coil member 140 connected to the first ground line 600. When the current collected in the blocking unit 100 moves to the power distribution unit B along the first grounding line 600, a short circuit may occur, thereby causing a risk of electric shock and fire. Bar, in order to prevent this, current flows in one direction from the power distribution unit (B) to the first coil member 140 by the diode member (D).

In addition, the second coil is provided inside the case 110 of the leakage current blocking unit 100 together with the first coil member 140 and is spaced apart from the first coil member 140 at a predetermined interval.

(400) and a second discharge line (900) connected to the second wire (500) to release the leakage current collected in the leakage current blocking unit (100). can do.

At this time, in the first discharge line 800 and the second discharge line 900, the leakage current collected in the leakage current blocking unit 100 is transferred from the second coil member 150 to the first wire 400 and It is possible to prevent current from flowing into the second coil member 150 through the first wire 400 and the second wire 500 while allowing each to be smoothly discharged to the second wire 500. Diode members (D) for limiting the current flow direction in one direction may be provided, respectively.

The second light emitting body 112 enables the user to visually check the direction of the current flowing along the phase power line determined by the direction of the plug of the electronic product to which the user is coupled, and the diode member (D) and the It can play a role of preventing a short circuit from occurring due to current friction between the first wire 400 and the second wire 500.

For example, when the first electric wire 400 serves as a phase power supply wire according to the direction in which the plug of the electronic product is coupled to the connection part C, the current flowing in the first electric wire 400 is the first electric wire 400. It flows into the first emission line 800 connected to the electric wire 400, and at this time, flows into the second coil member 150 by the diode member D provided in the first emission line 800. can be prevented, and in the second light emitting body 112 provided in the first emission line 800 from the second coil member 150 through the first emission line 800, the first wire ( 400) and the current flowing from the first wire 400 to the first emission line 800 meet to drive the second light emitting element 112, thereby consuming current to the first emission line 800. It is possible to prevent a short circuit between 800 and the first wire 400 from occurring.

Conversely, even when the second wire 500 serves as a phase power supply line according to the direction in which the plug is coupled to the connection part C, the occurrence of a short circuit can be prevented through the same method as in the above example. there is.

That is, the current flowing in the second electric wire 500 serving as the phase power supply line flows into the second emission line 900 connected to the second electric wire 500, and the second emission line 900 Inflow into the second coil member 150 is prevented by the diode member D provided in the second coil member 112 provided in the second emission line 900. In 150, the leakage current flowing toward the second wire 500 through the second discharge line 900 and the current flowing from the second wire 500 to the second discharge line 900 meet, By driving the two light-emitting elements 112, it is possible to prevent a short circuit from occurring between the second emission line 900 and the second wire 500 by consuming current.
