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.

Abstract

The invention discloses a circuit power failure and leakage protection device, and relates to the technical field of circuit safety protection. The circuit power failure and leakage protection device comprises a magnetic ring, a winding coil, an electromagnet and an adjusting switch; one side of the winding coil winds the magnetic ring while the other side thereof winds an iron core to form the electromagnet; the magnetic ring is also wound by a live wire and a null line; the live wire and the null line winding on the magnetic ring are different in number of turns; the live wire and the null line are connected through the adjusting switch; the adjusting switch is a metal conductive sheet with two contacts on the same sides; the two contacts are respectively in contact with the live wire and the null line; one end of the adjusting switch is connected with one end of a plastic spring while the other end of the plastic spring is fixed; the other end of the adjusting switch is connected with a magnet through an insulating block; different poles of both magnet and the electromagnet are arranged oppositely. The circuit power failure and leakage protection device can cut off the circuit in time as long as electric shock occurs when the circuit is put through electricity, and cannot electrify the circuit at once to prevent electric shock when the circuit is electrified after the power failure.

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...
