[0024] As Figure 1-4 shown,

[0025] A magnetic floating safety electrical device includes a chassis 1, a magnetic floating device 2 and a controller 3; the magnetic floating device 2 and the controller 3 are respectively installed inside the chassis 1, and the magnetic floating device 2 and the controller 3 are electrically connected; the controller 3 includes a main control board 4, a fee control switch 5, a dual power switch 6 and a mutual inductor 7; a middle layer board 17 is installed inside the chassis 1, and the main control board 4, the fee control switch 5, the dual power switch 6 and the mutual inductor 7 are respectively installed on the middle layer board 17, and the main control board 4 is respectively electrically connected to the fee control switch 5, the mutual inductor 7 and the magnetic floating device 2, and the main control board 4 is used to control the action of the fee control switch 5; the input and output wires of the magnetic floating device 2 are connected to the mutual inductor 7, and the mutual inductor 7 is used to detect the current of the magnetic floating device 2 and feed back the current information to the main control board 4, and the main control board 4 is used to detect the voltage of the magnetic floating device 2; the fee control switch 5 is electrically connected to the magnetic floating device 2, and the magnetic floating device 2 is electrically connected to the dual power switch 6; in this embodiment, the commercial power is electrically connected to the main control board 4 to supply power to the main control board 4; in addition, the commercial power is electrically connected to the fee control switch 5, and through the fee control switch 5, the commercial power can be electrically connected to the magnetic floating device 2, and the commercial power thus enters the magnetic floating device 2; under the action of the magnetic floating device 2, the safe conversion of the commercial power is realized, and finally it is output through the dual power switch 6; the output end of the fee control switch 5 is connected to the input end of the wiring terminal 16, the output end of the wiring terminal 16 is connected to the input end of the dual power switch 6, and the output end of the dual power switch 6 is connected to the safety electrical output switch.

[0026] In the above solution, as Figure 5As shown in the figure, two ports for connecting the magnetic levitator 2 are provided on the main control board 4, which will be respectively connected to the voltage at the output end of the magnetic levitator 2 and the voltage at the input end of the magnetic levitator 2, mainly for detecting the voltage condition of the magnetic levitator 2; moreover, two ports for connecting the input current transformer 7 and the output current transformer 7 are also provided on the main control board 4 (signal lines can be used), and the current information detected by the current transformer 7 is fed back to the main control board 4, and the input end and the output end of the terminal 16 on the magnetic levitator 2 will be connected to the current transformer 7 through wires (actually, the wires pass through the inner middle induction hole of the current transformer 7); in addition, the mains power enters and is connected to the fee control switch 5, and then connected to the magnetic levitator 2, so that the mains power can be introduced into the magnetic levitator 2. After safety power conversion, the output safety power will pass through the double power switch 6 (the double power switch 6 refers to having a normal end and a standby end, and the two can be switched. When the safety power coming out of the magnetic levitator 2 will be connected to the normal end of the double power switch 6; if there is a problem with the magnetic levitator 2, it will be connected to the standby end of the double power switch 6 through the air switch), and finally output through the safety power output switch.

[0027] As a preferred embodiment; the magnetic levitator 2 includes an iron core (not shown in the figure) and a coil 8, the iron core is arranged inside the coil 8, the coil 8 includes a winding layer 9 and a barrier rod 10, the winding layer 9 is arranged on the outer side of the iron core, and the barrier rod 10 is installed between adjacent winding layers 9, and the barrier rod 10 forms a heat dissipation channel 11 between adjacent winding layers 9. By installing the barrier rod 10 between adjacent winding layers 9, on the one hand, the heat dissipation channel 11 is formed, and on the other hand, the adjacent winding layers 9 are separated to avoid the situation that the insulation layer on the winding layer 9 is broken down or damaged due to contact, thereby improving the use effect and use quality of the coil structure.

[0028] As a preferred embodiment; the winding layer 9 is a copper sheet layer (the winding layer 9 is composed of a copper sheet layer and its own insulation layer), the iron core is made of silicon steel blocks, and the silicon steel blocks are composed of several silicon steel sheets; it can be understood that mainly pure copper sheets are used in the winding process, and this structure is sheet-shaped. Using pure copper sheets can enable it to withstand a larger current and has a better use effect; in addition, the whole iron core is a silicon steel block, and the silicon steel block is formed by laminating and tightly pressing several silicon steel sheets, aiming to enhance the effect of magnetic-electric conversion.

[0029] As a preferred embodiment; the material of the barrier rod 10 is ceramic, the barrier rod 10 is of a rectangular structure, and several barrier rods 10 are installed between adjacent winding layers 9 to form a ring-shaped heat dissipation channel 11. The structural design of the barrier rod 10 enables the barrier rod 10 to penetrate the upper and lower parts of the coil 8, making the coil 8 have a hollow structure up and down at this place, thus greatly improving the heat dissipation efficiency; in addition, the setting of multiple barrier rods 10 forms a closed-loop heat dissipation channel 11, which has a large heat dissipation range and good heat dissipation effect.

[0030] As a preferred embodiment, the magnetic levitator 2 further includes silicon steel bars, which are connected to the iron core. The silicon steel bars are composed of several silicon steel sheets. The number of the iron cores and the coils 8 is three groups, and the silicon steel bars are respectively connected to the three iron cores. In this application, the silicon steel bars are respectively connected to the three iron cores and can be an integrally formed structure. In this structure, the connection of the three coils 8 is more compact, which can meet the use of three-phase electricity.

[0031] As a preferred embodiment, the silicon steel bar includes a first silicon steel sub-bar 12 and a second silicon steel sub-bar 13. The first silicon steel sub-bar 12 and the second silicon steel sub-bar 13 are respectively connected to the top and bottom of the iron core. A first fixing frame 14 is arranged on the first silicon steel sub-bar 12, and a second fixing frame 15 is arranged on the second silicon steel sub-bar 13. A plurality of wiring terminals 16 are further installed on the first fixing frame 14. The wiring terminal 16 is provided with an input end and an output end. By adopting the first fixing frame 14 and the second fixing frame 15, the silicon steel sheets on the first silicon steel sub-bar 12 and the second silicon steel sub-bar 13 can be effectively pressed, further ensuring the effect of magnetoelectric conversion. Moreover, the wiring terminal 16 can be installed, and the wire can be directly introduced into the coil 8 from the wiring terminal 16, which can effectively reduce the wiring path and make the magnetic levitator 2 more reliable and stable.

[0032] As Figure 6 shown, A, B, and C refer to the three-phase electricity accessed from the mains, which are live wires, and N refers to the neutral wire accessed from the mains. a, b, and c refer to the three-phase electricity of the safe output, which are live wires, and n refers to the neutral wire of the safe output. A, B, C, a, b, c, N, and n are respectively connected to the wiring terminal 16. A, B, C, and N are one winding, and a, b, c, and n are another winding. When the mains is accessed and powered on, it conducts with the coil 8 to form a current, and then generates a magnetic field, which is the process of electricity-to-magnetism conversion. After generating the magnetic field, a current will be generated on the other winding (a, b, c, n) of the coil 8, which is the process of magnetism-to-electricity conversion. Finally, it can be output through the safe electricity output switch (the safe electricity output switch is arranged on the side of the chassis 1 and is electrically connected). In the traditional mains connection, both the live wire and the neutral wire in the mains are conducted to the ground. When a person touches the leaking wire, the live wire, the neutral wire, the ground, and the person form a conduction, and then the person is electrocuted. After adopting this device, the live wire and the neutral wire are isolated from the ground, and no conduction is formed on the person. The current passing through the person is extremely small, less than 1.0 mA (the perception current of the human body is about 1.1 mA). Therefore, it basically will not cause harm to the human body.

[0033] In this application, the magnetic floating device 2 (i.e., the coil structure) is installed inside the chassis 1 of the device. A number of terminals 16 are used to connect to the mains power, and then through wires, it is connected to the inside of the coil 8 (extending through the heat dissipation channel 11), forming a connection with the winding layer 9 (winding method). When powered on, a magnetic field is generated, first electromagnetic conversion is carried out, and then magnetoelectric conversion output is carried out.

[0034] It should be pointed out that the main problems in the prior art are as follows: Since the phase electricity in the mains power is conducted to the ground, and when a person touches a wire with broken skin and current, a conduction will be formed among the phase electricity, the human body and the ground, which will in turn cause an electric shock accident and cause immeasurable losses to people's lives and property.

[0035] Therefore, after the improvement of this application, by providing the magnetic floating device 2 and the controller 3, the mains power is input into the magnetic floating device 2 and controlled by the controller 3 to realize the process of electric-to-magnetic and magnetic-to-electric conversion of the magnetic floating device 2, so that the phase electricity in the mains power can be isolated from the ground, and no conduction is formed among the live wire, the neutral wire, the ground and the human body. The current passing through the human body is extremely small and basically will not cause harm to the human body, thus greatly reducing the occurrence of electric shock accidents.

[0036] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary engineering and technical personnel in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
