Description

Technical Field

[0001] The utility model relates to the technical field of safe electrical equipment, in particular to a silent-operating safe electrical device. Background Art

[0002] Safety electrical device refers to a device that can be connected to the mains and achieve magneto-electric conversion. With the safety electrical device, the neutral wire and the live wire are isolated from the ground, and the current will not be directly conducted to the human body, and sparks and leakage will not be generated, making the electricity use process very safe. It can be widely used in hospitals, the military and other places.

[0003] At present, during the use of existing safety electrical devices, a relatively high-power cooling fan is used for heat dissipation because it is necessary to enhance the heat dissipation effect of the device and ensure the quality of use of the device. However, the use of a relatively high-power cooling fan will cause a relatively high noise, which will greatly reduce the use effect (quiet effect) of the device. Moreover, the energy consumption of the relatively high-power cooling fan is also relatively large, which does not meet the requirements of energy conservation and emission reduction. For this reason, we propose a safety electrical device that operates silently. Utility Model Content

[0030] A silent-running safety electrical device comprises a chassis 1, a magnetic levitation device 2, a controller 3 and a heat dissipation mechanism; the chassis 1 is respectively installed with a magnetic levitation device 2 and a controller 3; the magnetic levitation device 2 and the controller 3 are electrically connected; the heat dissipation mechanism comprises a first fan (not shown), a second fan (not shown) and a third fan 6, the upper side of the chassis 1 is respectively installed with the first fan and the second fan; the lower side of the chassis 1 is installed with the third fan 6, a temperature sensor is installed inside the chassis 1, the temperature sensor (not shown) is signal-connected to the controller 3, the first fan, the second fan and the third fan 6 are respectively electrically connected to the controller 3; in this embodiment, a shelf is provided in the middle of the chassis 1, the magnetic levitation device 2 is provided in the lower inner part of the chassis 1, and the controller 3 is provided in the upper inner part of the chassis 1, such a design makes the chassis 1 is more stable (the center of gravity is at the bottom); when working, the controller 3 controls the first fan to run. The function of the first fan is to form long-term air convection inside the device and dissipate heat. The use of the first fan can slow down the temperature rise inside the device. When the temperature sensor detects that the temperature inside the device rises to the set temperature value, the signal will be transmitted to the controller 3, and the controller 3 will control the start of the second fan and the third fan 6. Through the operation of the second fan and the third fan 6, the heat can be quickly dissipated. When the temperature drops to the set temperature value 2, the operation of the second fan and the third fan 6 will be stopped, and the operation of the first fan will continue to be started, and the cycle will continue; when the first fan is running, the second fan and the third fan 6 can be the air inlet, and when the second fan and the third fan 6 are running, the first fan can be the air inlet.

[0031] As a preferred embodiment; the first louver grille 7 and the second louver grille 8 are respectively provided on the upper part of the side of the chassis 1, and the first louver grille 7 and the second louver grille 8 are respectively fixed to the first fan and the second fan through the first mounting frame 9 and the second mounting frame 10; the first louver grille 7 and the second louver grille 8 are provided to facilitate the internal and external circulation of gas, and the first mounting frame 9 and the second mounting frame 10 are provided with a plurality of nuts at different positions, so that fans of different specifications can be installed, thereby expanding the scope of use; in addition, filter cotton can also be installed inside the first mounting frame 9 and the second mounting frame 10, and the functions of the filter cotton are: first, to filter air impurities and improve the control quality, and second, to block noise and further improve the silent operation effect of the device.

[0032] As a preferred embodiment; a heat dissipation hole 11 is provided on the lower side of the chassis 1, and the third fan 6 is installed on the inner side of the chassis 1 facing the heat dissipation hole 11; the third fan 6 is mainly installed on the lower side of the chassis 1 so that it can face the maglev 2. The maglev 2 dissipates more heat, and being installed here can quickly dissipate the heat of the maglev 2, and the effect is better.

[0033] As a preferred embodiment; the first fan adopts a 12V silent cooling fan, the second fan and the third fan 6 both adopt a 220V powerful cooling fan, and the third fan 6 is provided with two and arranged side by side; it can be understood that the main function of the first fan is to form long-term air convection and heat dissipation inside the device, and to achieve the effect of slowing down the temperature rise inside the device; the second fan and the third fan 6 can work when the temperature rises to a set temperature value. In this process, air can be taken in from the first louver grille 7. If the third fan 6 is set to one, part of the air will be discharged from the second fan, and the other part will be discharged from the third fan 6. If the third fan 6 is set to two or more, the airflow will flow downward; in the above two situations, the first one can dissipate more heat to the controller 3 and less heat to the magnetic levitation device 2, and the use effect is better; the second one can dissipate less heat to the controller 3 and more heat to the magnetic levitation device 2, and the use effect is better.

[0034] As a preferred embodiment, the temperature sensor is arranged inside the magnetic float 2. It can be understood that three coil structures are arranged on the magnetic float 2, and the temperature sensor can be arranged in the gap between adjacent coil structures. Such a position setting makes temperature detection more accurate.

[0035] As a preferred embodiment; the magnetic levitation device 2 includes an iron core (not shown) and a coil 12, the iron core is arranged inside the coil 12, the coil 12 includes a winding layer 13 and a blocking rod 14, the winding layer 13 is arranged on the outside of the iron core, and the blocking rod 14 is installed between adjacent winding layers 13, and the blocking rod 14 forms a heat dissipation channel 15 between adjacent winding layers 13; by installing the blocking rod 14 between adjacent winding layers 13, a heat dissipation channel 15 is formed, and adjacent winding layers 13 are separated to avoid contact between them, thereby preventing the insulating layer on the winding layer 13 from being punctured or damaged, thereby improving the use effect and quality of the coil structure.

[0036] As a preferred embodiment, the winding layer 13 is a copper sheet layer (the winding layer 13 is composed of a copper sheet layer and its own insulating layer). It can be understood that pure copper sheets are mainly used in the winding process. The structure is in sheet form. The use of pure copper sheets can make it withstand larger currents and have better use effects.

[0037] As a preferred embodiment, the iron core adopts a silicon steel block, which is composed of several silicon steel sheets. It can be understood that the whole iron core is a silicon steel block, and the silicon steel block is formed by stacking and pressing several silicon steel sheets, in order to enhance the effect of magnetoelectric conversion.

[0038] As a preferred embodiment; the material of the barrier rod 14 is ceramic, the barrier rod 14 is a rectangular structure, and a plurality of barrier rods 14 are installed between adjacent winding layers 13, so that they can form a heat dissipation channel 15 with an annular structure. The structural design of the barrier rod 14 allows the barrier rod 14 to penetrate the upper and lower parts of the coil 12, so that the coil 12 has a hollow structure at the top and bottom, thereby greatly improving the heat dissipation efficiency; in addition, the arrangement of multiple barrier rods 14 forms a heat dissipation channel 15 with a closed-loop structure, which has a large heat dissipation range and a good heat dissipation effect.

[0039] As a preferred embodiment; the magnetic levitation device 2 also includes silicon steel bars, which are connected to the iron core, and the silicon steel bars are composed of several silicon steel sheets. The iron core and the coil 12 are arranged in three groups, and the silicon steel bars are connected to the three iron cores respectively; in the present application, the silicon steel bars are connected to the three iron cores respectively, which can be an integrated molding structure. Under this structure, the connection of the three coils 12 is more compact, which can meet the use of three-phase electricity.

[0040] As a preferred embodiment; the silicon steel strip includes a first silicon steel strip 16 and a second silicon steel strip 17, the first silicon steel strip 16 and the second silicon steel strip 17 are connected to the top and the bottom of the iron core respectively; the first silicon steel strip 16 is provided with a first fixing frame 18, and the second silicon steel strip 17 is provided with a second fixing frame 19; the first fixing frame 18 is also provided with a plurality of terminals 20. By adopting the first fixing frame 18 and the second fixing frame 19, the silicon steel sheets on the first silicon steel strip 16 and the second silicon steel strip 17 can be effectively pressed, further ensuring the effect of magnetoelectric conversion; moreover, the terminal 20 can be installed, and the wire is directly introduced into the inside of the coil 12 from the terminal 20, which can effectively reduce the wiring path, making the magnetic float 2 more reliable and stable.

[0041] like Figure 7As shown, A, B, C refer to the three-phase electricity connected to the mains, which is the live wire, and N is the neutral wire connected to the mains; a, b, c refer to the three-phase electricity output for safety, which is the live wire, and n is the neutral wire for safety output; A, B, C, a, b, c, N, n are connected to the wiring terminals respectively, A, B, C, N is a winding, and a, b, c, n is another winding. When the mains is connected and energized, it conducts with the coil 12 to form a current, thereby generating a magnetic field, which is an electric-to-magnetic process; after the magnetic field is generated, a current will be generated on the other winding (a, b, c, n) of the coil 12, which is a magnetic The process of power transfer can finally be output through the safety electrical output switch (set on the side of the chassis 1, electrically connected); in the traditional mains power connection, the live wire and the neutral wire in the mains are both connected to the ground. When the human body touches the leaking wire, the live wire, the neutral wire, the ground and the human body are connected, and then the human body is injured by electric shock; after adopting the present device, the live wire and the neutral wire are isolated from the ground, and are not connected to the human body. The current passing through the human body is very small, which is less than 1.0 mA (the human body's perceived current is about 1.1 mA), so it basically does not cause harm to the human body.

[0042] In the present application, the magnetic levitation device 2 (i.e., the coil structure) is installed inside the chassis 1 of the device, and a number of terminal blocks 20 are used to connect to the mains power, and then connected to the interior of the coil 12 through wires (extending through the heat dissipation channel 15), forming a connection with the winding layer 13 (winding method). When powered on, a magnetic field is generated, and electromagnetic conversion is first performed, and then magnetoelectric conversion output is performed.

[0043] It should be pointed out that the main problem in the prior art is that the existing safety electrical device will use a relatively high-power cooling fan for heat dissipation during use. However, the use of a relatively high-power cooling fan will cause a relatively high noise, and the use of a relatively high-power cooling fan will also consume relatively large amounts of energy, which does not meet the requirements of energy conservation and emission reduction.

[0044] Therefore, after the improvement of the present application, a first fan, a second fan and a third fan 6 are provided, and the first fan adopts a low-power 12V silent cooling fan. When the device is working, the first fan is always running. The function of the first fan is to form long-term air convection and dissipate heat inside the device. The use of the first fan can achieve the effect of slowing down the temperature rise inside the device. When the temperature inside the device rises to the set temperature value, the second fan and the third fan 6 will be started to quickly cool down the device. Since the utility model uses the first fan for a long time to dissipate heat and can suppress the rapid rise in temperature, the device can achieve low-noise heat dissipation and silent operation, and at the same time can reduce energy consumption.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
