Description

Leakage Current Blocking Device {LEAKAGE CURRENT BLOCKING DEVICE}

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

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

In general, if the leakage current flows more than 15mA, it causes convulsions, and when the leakage current flows more than 50mA, it leads to death.

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

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

When electrical equipment, for example, electrical equipment such as an electrical outlet, electric heater, or electric lamp, is submerged in water and a human body comes into contact with the water or a metal housing energized through the water, the exposed conductor of the electrical equipment passes through the water and the human body to the ground plane. 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 the power lines is a problem that, when the insulation between the two wires is lowered and the electrical conductivity is increased, a sudden current flows, causing damage to the electrical equipment such as fire or short circuit.

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

However, when a fluid with high electrical conductivity is filled between the two wires due to submersion, etc., 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 a metal mesh to the bare charging part to prevent electric shock by passing the current leaking from the bare charging part to the conductive metal plate or metal mesh when it is submerged. is starting

The metal plate or mesh is connected to the neutral and earth terminals among 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 when submerged and electrically composing in parallel with the human body, It can be seen as limiting the flow of current.

However, these metal plates or metal meshes do not shield the electric field radially generated from the bare charging part, so they cannot effectively block the leakage current, and there is a problem in that the installation space is limited.

Therefore, a method for solving such problems is required.
