Problems solved by technology
[0002] Whether it is household electricity or industrial electricity, there may be a risk of electric shock. When there is a power outage, all lines, electrical appliances, and equipment are out of power. At this time, people lower their awareness of safety protection and install and maintain electrical equipment at will. At this time, if a sudden call comes in, it is very likely to cause electric shock to the human body, causing casualties.

The invention discloses a circuit power failure and leakage protection device, which relates to the technical field of circuit safety protection and comprises a magnetic ring, a winding coil, an electromagnet and a regulating switch. One side of the winding coil is wound on the magnetic ring, and the other side is wound on the iron core. The electromagnet is formed on the magnetic ring, and the live wire and the neutral wire are wound on the magnetic ring. The number of turns of the live wire and the neutral wire wound on the magnetic ring is different. The live wire and the neutral wire are connected by an adjustment switch. The metal conductive sheet of the head, the two contacts are in contact with the live line and the neutral line respectively, one end of the adjustment switch is connected to one end of the plastic spring, the other end of the plastic spring is fixed, and the other end of the adjustment switch is connected to a magnet through an insulating block, the magnet and the electromagnetic Iron opposite poles are set. The device can cut off the line in time if an electric shock occurs when the line is powered, and when the line is powered off and the power comes in again, the line will not be energized immediately to prevent the occurrence of electric shock.
Description
technical field [0001] The invention relates to the technical field of circuit safety protection. Background technique [0002] Whether it is household electricity or industrial electricity, there may be a risk of electric shock. When there is a power outage, all lines, electrical appliances, and equipment are out of power. At this time, people lower their awareness of safety protection and install and maintain electrical equipment at will. At this time, if a sudden call comes in, it is very likely to cause an electric shock to the human body, causing casualties. [0003] Therefore, in view of the above problems, a device is now provided that can cut off the circuit in time when the human body gets an electric shock, and will not immediately energize the circuit when the power fails and comes back, so as to ensure safety. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a circuit power failure and leakage protect...
