Description

Technical Field

[0001] The invention belongs to the technical field of mutual inductors, in particular to a voltage mutual inductor. Background Art

[0002] A voltage transformer is a device used for voltage conversion. Its main function is to provide power to measuring instruments and relay protection devices to facilitate the measurement of line voltage, power and electric energy. In addition, when a line fault occurs, the voltage transformer can also protect important equipment, motors and transformers in the line from damage.

[0003] For example, patent CN114203396B discloses an electromagnetic voltage transformer, including a transformer body, a protective shell disposed on the outer side of the transformer body, two ventilation hoses disposed on the protective shell, a heat dissipation box disposed in the middle of the ventilation hose, a plurality of heat dissipation fins disposed inside the heat dissipation box, heat dissipation fans disposed at both ends of the ventilation hose, a mounting seat disposed inside the protective shell, a fixing seat disposed at the bottom of the transformer body, and a stabilizing component disposed in the fixing rod. Heat is dissipated through the ventilation hose, the heat dissipation box and the heat dissipation fan, thereby ensuring the sealing of the protective shell and preventing moisture from entering the protective shell in a humid environment and causing damage to the transformer. The mounting seat, the fixing seat and the stabilizing component can facilitate disassembly of the transformer body and improve the efficiency of maintenance and replacement.

[0004] Although the above technology can dissipate heat for the transformer body to a certain extent, in actual use, the outside air usually contains dust. During the heat dissipation process, the dust will enter the heat dissipation box through the ventilation hose and accumulate on the surface of the heat dissipation fins for a long time to form a dust layer, which affects the heat conduction effect between the heat dissipation fins and the air, and thus affects the heat dissipation.

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0046] like Figures 1 to 6 As shown, a voltage transformer described in the present invention includes a protection mechanism, a main body component, a circulation mechanism, a heat exchange mechanism, a ventilation mechanism and a dust reduction mechanism.

[0047] The protection mechanism comprises a protection cabin 1 and a protection roof 5 arranged above the protection cabin 1, wherein the protection roof 5 is a triangular structure for shielding rainwater.

[0048] The main body component includes a containing shell 15 and a coil shell 26, wherein the coil shell 26 is used to store the magnetic induction coil, the outer wall of the coil shell 26 is provided with a heat sink, which is fixedly installed on the inner wall of the containing shell 15, the containing shell 15 is arranged inside the protective cabin 1, and the inner cavity of the containing shell 15 is used to store insulating oil, and the insulating oil is used to play the role of insulation and heat conduction.

[0049] The circulation mechanism is used to control the circulation of the insulating oil in the housing 15 , and by controlling the circulation of the insulating oil, the temperature of the inner cavity of the housing 15 is kept uniform.

[0050] The heat exchange mechanism includes a mounting shell 12, a heat exchange box 19, a control sheet 20 and a heat exchange plate 21. The mounting shell 12 is fixedly mounted on the outer wall of the accommodating shell 15. The heat exchange box 19 is fixedly mounted in the mounting shell 12. The circulation mechanism controls the insulating oil to flow through the inner cavity of the heat exchange box 19. The circulation mechanism includes a circulation pump and a filter cartridge.

[0051] The output end of the circulation pump is connected to the inner cavity of the accommodating shell 15, and the other end of the circulation pump is connected to the inner cavity of the heat exchange box 19. The circulation pump is used to provide power for the circulation of the insulating oil.

[0052] One end of the filter cartridge is connected to the inner cavity of the housing 15, and the other end of the filter cartridge is connected to the inner cavity of the heat exchange box 19. The filter cartridge is used to filter impurities in the insulating oil. The insulating oil in the housing 15 is pumped to the heat exchange box 19 by generating negative pressure through a circulating pump, and is filtered through the filter cartridge in the process.

[0053] The control sheet 20 is fixedly mounted on the inner wall of the heat exchange box 19, and the heat exchange plate 21 is fixedly mounted on the hot end of the control sheet 20 and extends to the outer wall of the mounting shell 12. The control sheet 20 is a common semiconductor refrigeration sheet. The cold end of the control sheet 20 is located in the inner cavity of the heat exchange box 19, which is used to absorb the heat energy in the insulating oil. When the control sheet 20 is working, the heat is dissipated through the heat exchange plate 21. The heat exchange plate 21 is preferably a copper plate. Compared with CN114203396B, in an electromagnetic voltage transformer, the heat dissipation method of the heat dissipation box at a fixed position of the transformer body can help the internal coil of the voltage transformer to dissipate heat evenly during actual use, thereby improving the heat dissipation efficiency.

[0054] The ventilation mechanism is used to control the outside air to blow toward the heat exchange plate 21 , and generate airflow through the ventilation mechanism, thereby increasing the air flow speed of the outer wall of the heat exchange plate 21 , thereby improving the heat dissipation efficiency of the heat exchange plate 21 , and is used to improve the refrigeration efficiency of the control plate 20 .

[0055] The dust reduction mechanism includes a control pump 13 and a drainage nozzle 17. The output end of the control pump 13 is connected to the drainage nozzle 17. The output end of the drainage nozzle 17 is inclined toward the airflow generated by the ventilation mechanism. The control pump 13 is connected to an external water source and discharged by the drainage nozzle 17. The drainage nozzle 17 is an atomizing nozzle. The generated atomized water droplets are synchronously blown toward the heat exchange plate 21 with the airflow generated by the ventilation mechanism. On the one hand, the water droplets are attached to the outer wall of the heat exchange plate 21 to improve the heat dissipation efficiency. At the same time, the flow of water droplets can effectively prevent dust from adhering. Compared with CN114203396B, an electromagnetic voltage transformer, the method in which the outside air is directly blown to the heat dissipation fins can effectively prevent dust from adhering, and the heat dissipation efficiency can be maintained during actual use.

[0056] As a preferred embodiment of the present invention, the ventilation mechanism includes an air duct 3, a control fan 16 and a connecting pipe 7. The air duct 3 is fixedly installed on the inner wall of the protective cabin 1, and the upper end of the air duct 3 is located below the protective ceiling 5 to prevent rainwater from flowing into the inner cavity of the air duct 3.

[0057] The control fan 16 is fixedly installed on the inner wall of the air duct 3 . The control fan 16 is composed of a motor and fan blades. The motor controls the fan blades to rotate, thereby generating airflow in the inner cavity of the air duct 3 .

[0058] One end of the connecting pipe 7 is fixedly connected to the outer wall of the air guide pipe 3, and the other end of the connecting pipe 7 is fixedly connected to the outer wall of the heat exchange plate 21. When the fan 16 is controlled to generate airflow, it blows toward the heat exchange plate 21, thereby increasing the air flow speed of the outer wall of the heat exchange plate 21.

[0059] As a preferred embodiment of the present invention, a mesh plate 4 is fixedly installed on the inner wall of the protective ceiling 5, and the mesh plate 4 is located on the inclined surface outside the protective ceiling 5. A drainage box 6 is fixedly installed on the bottom of the protective ceiling 5, and the drainage box 6 is located directly below the mesh plate 4. In rainy weather, rainwater falls on the protective ceiling 5 and flows along the inclined surface of the protective ceiling 5. During the flowing process, dust particles are filtered by the mesh plate 4 and then flow into the inner cavity of the drainage box 6.

[0060] A filter tube 22 is fixedly installed at the bottom of the drainage box 6. Filter cotton is arranged in the filter tube 22. The filter cotton is a common sponge. When rainwater in the drainage box 6 passes through, it is further filtered by the filter cotton in the filter tube 22.

[0061] A storage box 18 is fixedly mounted on the outer wall of the protection cabin 1 , and the top of the storage box 18 is connected to the bottom of the filter tube 22 , and rainwater passing through the filter tube 22 flows into the inner cavity of the storage box 18 due to gravity.

[0062] The storage box 18 is used to provide liquid to the control pump 13, and further provide rainwater to the control pump 13 when the heat exchange plate 21 dissipates heat, thereby achieving a heat dissipation effect.

[0063] As a preferred embodiment of the present invention, an ultraviolet light source 23 is fixedly installed on the inner wall of the protective cabin 1, and the light-emitting end of the ultraviolet light source 23 extends to the inner cavity of the storage box 18. The ultraviolet light source 23 is a common ultraviolet lamp. Since the storage box 18 needs to store rainwater for a long time, in order to prevent the growth of algae and bacteria caused by long-term storage of rainwater, ultraviolet disinfection is used to reduce the survival rate of algae and bacteria, thereby extending the time for the storage box 18 to store rainwater.

[0064] An adapter box 29 is fixedly installed on the inner wall of the protection cabin 1, and the heating end of the ultraviolet light source 23 extends to the inner cavity of the adapter box 29. The heating end of the ultraviolet light source 23 extending to the inside of the adapter box 29 needs to be insulated to prevent short circuit.

[0065] A transition box 14 is fixedly installed on the outer wall of the mounting shell 12, the inner cavity of the transition box 14 is connected to the input end of the control pump 13, the top of the adapter box 29 is connected to the storage box 18 through a conduit, and the transition box 14 is connected to the bottom of the adapter box 29 through a conduit, wherein the adapter box 29 is a sealed structure. When the control pump 13 is working, rainwater in the storage box 18 is sucked into the adapter box 29, and then flows into the control pump 13 from the transition box 14, and is finally discharged from the drainage nozzle 17 to improve the heat dissipation efficiency of the heat exchange plate 21 while cleaning the outer wall of the heat exchange plate 21.

[0066] In addition, when the control pump 13 extracts rainwater in the storage box 18, the rainwater flows into the transfer box 29. At this time, the rainwater takes away the heat energy of the heating end of the ultraviolet light source 23, thereby dissipating the heat for the ultraviolet light source 23 and maintaining the working state of the ultraviolet light source 23.

[0067] As a preferred embodiment of the present invention, a guide tube 27 is fixedly installed on the inner wall of the storage box 18, and a through hole is opened at the bottom of the guide tube 27 for liquid to enter. By controlling the flow of rainwater inside the storage box 18, the rainwater enters the interior of the guide tube 27 through the through hole at the bottom of the guide tube 27.

[0068] The inner wall of the flow guide pipe 27 is rotatably mounted with a flow guide auger 10 , the outer wall of the flow guide auger 10 is slidably fitted with the inner wall of the flow guide pipe 27 , and the axis of the flow guide pipe 27 coincides with the axis of the flow guide auger 10 .

[0069] A filter plate 34 is fixedly installed at the bottom of the guide pipe 27. The filter plate 34 is made of elastic material, and the inner wall of the filter plate 34 fits with the outer wall of the guide auger 10. When rainwater inside the storage box 18 enters the guide pipe 27, the guide auger 10 rotates. At this time, the rainwater flows toward one end of the guide pipe 27. During the flow, it penetrates into the inner cavity of the storage box 18 through the filter plate 34, completing further filtering of the rainwater. The impurities filtered by the filter plate 34 are scraped off by the rotation of the guide auger 10 and discharged from one end of the guide pipe 27, thereby achieving the cleaning of the filter plate 34 itself and maintaining the filtering effect of the filter plate 34.

[0070] It should be noted that in order to prevent rainwater inside the storage box 18 from flowing out of the guide tube 27, the liquid level in the inner cavity of the storage box 18 needs to be no higher than the bottom of the guide tube 27. How to control the liquid level inside the box is a common technical means in the field, which will not be elaborated here.

[0071] A control motor 2 is fixedly installed on the outer wall of the storage box 18. The output end of the control motor 2 extends to the inner cavity of the storage box 18 and is connected to the axial end of the diversion auger 10. The control motor 2 is used to provide power for the rotation of the diversion auger 10. It should be noted that since the output shaft of the control motor 2 needs to pass through the storage box 18, a sealed bearing needs to be provided at the contact position between the storage box 18 and the output shaft of the control motor 2.

[0072] As a preferred embodiment of the present invention, a control cylinder 24 is fixedly mounted on the inner wall of the storage box 18 , and one end of the control cylinder 24 is provided with an opening and the other end is closed.

[0073] A control auger 30 is rotatably installed on the inner wall of the control cylinder 24. The control auger 30 and the diversion auger 10 are connected by a transmission member, wherein the transmission member is a common belt pulley. The control auger 30 extends into the open end of the control cylinder 24. The control auger 30 is rotated to control the flow of rainwater into the inner cavity of the control cylinder 24.

[0074] A guide tube 25 is fixedly installed on the outer wall of the control tube 24. An inclined discharge hole is opened at the upper end of the guide tube 25, and the discharge hole faces the through hole at the bottom of the guide tube 27. Therefore, when rainwater flows into the inner cavity of the control tube 24, it is discharged from the discharge hole of the guide tube 25 until it flows into the inner cavity of the guide tube 27.

[0075] In the process of controlling the rotation of the auger 30, not only can the rainwater be controlled to flow into the inner cavity of the guide tube 27, but the rainwater in the inner cavity of the storage box 18 can also be driven to flow, achieving a stirring effect, so that the ultraviolet light source 23 can evenly disinfect bacteria and algae in the rainwater.

[0076] As a preferred embodiment of the present invention, a support plate 32 is fixedly installed on the inner wall of the storage box 18, a sliding rod 31 is slidably installed on the inner wall of the support plate 32, the outer wall of the sliding rod 31 slides and fits with the inner wall of the support plate 32, an extrusion plate 33 is fixedly installed on the top of the sliding rod 31, the bottom of the extrusion plate 33 is elastically connected to the outer wall of the support plate 32, the bottom surface of the extrusion plate 33 is connected to the support plate 32 by a spring, and the elastic force of the spring controls the extrusion plate 33 to have a tendency to move away from the filter plate 34 in real time.

[0077] During the rotation of the guide auger 10 , the sliding rod 31 slides upward until the squeezing plate 33 squeezes the filter plate 34 , causing the filter plate 34 to bulge inward, thereby facilitating the guide auger 10 to scrape off impurities and improving the cleaning efficiency of the filter plate 34 .

[0078] As a preferred embodiment of the present invention, a reciprocating screw 11 is fixedly installed at one axial end of the control auger 30, and a control sleeve 28 is sleeved on the outer wall of the reciprocating screw 11. When the control auger 30 rotates, the reciprocating screw 11 is driven to rotate synchronously, thereby controlling the sleeve 28 to slide back and forth.

[0079] A guide rod is fixedly mounted on the inner wall of the storage box 18 , and the control sleeve 28 is slidably connected to the guide rod. By providing the guide rod, the control sleeve 28 can be prevented from deflecting when the reciprocating screw 11 rotates.

[0080] A pressing block 35 for pressing the sliding rod 31 is fixedly installed on the outer wall of the control sleeve 28. When the control sleeve 28 slides back and forth, it drives the pressing block 35 to move synchronously. The outer wall of the pressing block 35 is inclined. When the pressing block 35 slides back and forth, the pressing sliding rod 31 controls the extrusion plate 33 to press the filter plate 34.

[0081] A support frame 9 is fixedly installed on the outer wall of the mounting shell 12, and the inner wall of the support frame 9 is inclined. The inclined surface of the support frame 9 faces the outside of the protection cabin 1, and the water droplets flowing down from the outer wall of the heat exchange plate 21 are drained to the outside of the protection cabin 1 through the support frame 9.

[0082] An elastic layer 8 is fixedly mounted on the inclined surface of the support frame 9. The elastic layer 8 is located directly below the heat exchange plate 21. The elastic layer 8 is a common sponge. When the heat exchange plate 21 falls, the sponge is used as a buffer to prevent water droplets from splashing as much as possible.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
