Technical Field

The invention relates to the field of low-voltage power supplies, in particular to a radiation elimination device of a non-radiation power adapter.

Background

Practice proves that small electric appliances powered by the power adapter all have electromagnetic radiation! For example, when a power adapter is used for charging a mobile phone, the mobile phone and a charging connecting line can generate electromagnetic radiation, a state professional unit is entrusted to detect that the electromagnetic radiation value of the mobile phone during charging is up to 4304v/m, the high electromagnetic radiation exceeds the relevant national standard, if the mobile phone is frequently contacted with the electromagnetic radiation exceeding the standard, a person can be injured, and the detection proves that the electromagnetic radiation of the mobile phone during charging comes from the power adapter, so that the electromagnetic radiation of the power adapter is eliminated, and the fact that no radiation of a corresponding small electric appliance is required by health and is expected by people is ensured.

Market research and patent retrieval prove that no radiation elimination device of the radiationless power adapter exists at present.

Disclosure of Invention

The power converter of the power adapter generally adopts a single-ended flyback transformer switching power supply to work, the power converter can convert 220V alternating current power supply into stable low-voltage direct current (for example, 5V) to supply power to other electrical equipment, the working frequency of the switching power supply reaches 60-100KHZ, the output high-frequency power supply is rectified and filtered, but certain high-frequency harmonics still exist, when the power adapter works, the high-frequency harmonics can be automatically coupled into the low-voltage direct current power supply and are transmitted to corresponding small electrical appliances along with the direct current power supply through power lines, so that the small electrical appliances can generate electric radiation when the power adapter works, and the power adapter is the source of the electromagnetic radiation of the small electrical appliances.

The electromagnetic radiation is divided into magnetic field radiation and electric field radiation, the technical scheme mainly solves the electric field radiation, namely electric radiation, generated by high-frequency harmonic waves of the power adapter, and the electric field radiation of the power adapter is induced electric radiation, and the best method for solving the electric radiation with small energy is to shield the electric radiation and then directly grounding the shielded electric radiation to eliminate the electric radiation or couple a radiation source generating the electric radiation into a ground wire through a coupler to eliminate the electric radiation. The power adapter is a type 2 electric appliance specified by the state, the type 2 electric appliance is not provided with a grounding wire, and according to the 2.0.1 item of the national standard ' design Specification for grounding of Industrial and civil electric power devices ' (GBJ 65-83) ', the electric power devices are preferably grounded or connected to zero for ensuring the safety of human bodies and equipment. Because the potential of the power supply zero line is the same as that of the ground wire, the power supply zero line can be used for eliminating electric radiation instead of the ground wire under the condition of no power supply ground wire.

Because the power adapter adopts a single-phase power supply, zero and live wires in the power supply can not be distinguished, in order to solve the problem, the device adopts a neon lamp test pencil principle, one end of a neon lamp is connected with a supposed power supply zero line loop in the power adapter, the other end of the neon lamp is connected with a touch sheet, if the neon lamp does not emit light by touching the touch sheet with a hand, the supposed power supply zero line loop is proved to be correct, if the neon lamp emits light, a power supply plug of the power adapter needs to be replaced by a position to be plugged with a power socket, and the power supply zero line can be accurately found through the simple method.
