Description

Technical Field

[0002] The converter is an electrical device that changes the voltage, frequency, number of phases and other electrical quantities or characteristics of the power supply system. In addition to the main circuit, the converter also needs a trigger circuit (or drive circuit) that controls the on and off of the power switch elements and a control circuit that realizes the regulation and control of electric energy. The converter's trigger circuit consists of two parts: a pulse generator and a pulse output device.

[0003] When the current converter is in use, the converter is connected to the circuit, and the electrical components inside the converter adjust the electric energy. The electrical components will generate a lot of heat when working, and the heat is discharged from the vents to reduce the heat accumulation inside the converter and prevent the converter from internal failure when used for a long time.

[0004] During the use of traditional inverters, the electrical components inside the inverter will generate a lot of heat when working. The inverter discharges the internal heat to the outside through the vents. The heat discharge capacity of the vents is limited and cannot accelerate the heat discharge inside the inverter, causing heat to accumulate inside the inverter. When the internal temperature of the inverter is too high, it affects the normal use of the inverter. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] During the use of traditional converters, the electrical components inside the converter will generate a lot of heat when working. The converter discharges the internal heat to the outside through the vents. The heat discharge capacity of the vents is limited and cannot accelerate the heat discharge inside the converter, resulting in heat accumulation inside the converter. When the internal temperature of the converter is too high, the normal use of the converter is affected.

[0022] In view of this, the utility model provides an inverter that takes both waterproofing and heat dissipation into consideration. A current transformer is used to detect the current inside the inverter box. When abnormal current is detected, the control panel controls the carbon dioxide fire extinguisher to extinguish the fire inside the inverter box, and at the same time controls the alarm to sound an alarm. When the temperature sensor detects that the current temperature exceeds the set temperature, the control panel controls the heat dissipation device to work, and the heat dissipation device quickly blows out the heat inside the inverter box. The heat will not accumulate inside the inverter and will not affect the normal use of the inverter.

[0023] Embodiment 1: Figure 1 , 2, 3 and 4 show that a current transformer that takes into account both waterproofing and heat dissipation comprises a vent 1, a current transformer case 3 is mounted on the outer wall of the vent 1, an air inlet pipe 4 is mounted on the inner wall of the current transformer case 3, a current transformer 6 is mounted on the inner wall of the current transformer case 3, a control panel 10 is arranged on the outer wall of the current transformer case 3, and a temperature sensor 11 is mounted on the upper part of the interior of the current transformer case 3. The current transformer that takes into account both waterproofing and heat dissipation further comprises: a heat dissipation device 2, mounted inside the vent 1; a moisture-proof device 5, mounted inside the air inlet pipe 4; wherein the heat dissipation device 2 accelerates the speed at which the heat inside the current transformer case 1 is discharged to the outside, and the moisture-proof device 5 prevents water vapor from entering the interior of the current transformer case 3;

[0024] In the specific implementation process, it is worth pointing out that the temperature sensor 11 and the current transformer 6 are prior art, and the models are not specifically limited, as long as they meet the use requirements. The temperature sensor 11 and the current transformer 6 are electrically connected to the control panel 10. When the heat dissipation device 2 is working, the heat inside the converter box 3 is blown out. At the same time, the external air is from the air inlet pipe 4 and the inside of the converter box 3. When the external air passes through the moisture-proof device 5, the water vapor inside the air is absorbed;

[0025] Furthermore, a carbon dioxide fire extinguisher 7 is installed on the outer wall of the converter housing 3, a pipe 8 is installed on the top of the carbon dioxide fire extinguisher 7, and one end of the pipe 8 extends to the interior of the converter housing 3;

[0026] In the specific implementation process, it is worth pointing out that the carbon dioxide fire extinguisher 7 is a prior art and will not be elaborated on in detail. The carbon dioxide fire extinguisher 7 injects carbon dioxide into the converter box 3 through the pipeline 8 to extinguish the fire inside the converter box 3. The solenoid valve on the top of the carbon dioxide fire extinguisher 7 is electrically connected to the control panel 10.

[0027] Furthermore, an alarm 9 is installed on the outer wall of the converter housing 3;

[0028] In the specific implementation process, it is worth pointing out that the alarm 9 is electrically connected to the control panel 10, and the control panel 10 controls the operation of the alarm 9. The alarm 9 is a buzzer, which is the existing technology. The model is not specifically limited, and it can meet the use requirements;

[0029] Specifically, when using the inverter that takes into account both waterproofing and heat dissipation, when the short-circuit current fluctuation inside the inverter case 3 detected by the current transformer 6 is large, the alarm 9 is controlled to work through the control panel 10, and the carbon dioxide fire extinguisher 7 is controlled to work at the same time. The carbon dioxide fire extinguisher 7 injects carbon dioxide into the interior of the inverter case 3 through the pipeline 8 to prevent fire inside the inverter case 3. After the temperature sensor 11 detects that the temperature inside the inverter case 3 exceeds the set temperature, the heat dissipation device 2 is controlled to work through the control panel 10. The heat dissipation device 2 discharges the heat inside the inverter case 3 to the outside, and at the same time, external air enters the interior of the inverter case 3 from the air intake pipe 4, and the moisture-proof device 5 prevents water vapor from entering the interior of the inverter case.

[0030] Embodiment 2: By Figure 2 and 3 It can be known that the heat dissipation device 2 includes: a servo motor 201, which is detachably connected to the inner wall of the vent 1 and electrically connected to the control panel 10; a fan blade 202, which is detachably connected to the output end of the servo motor 201; two baffles 203, which are rotatably connected to the inside of the vent 1 through a pin shaft; two torsion springs 204, which are respectively installed on the outer walls of the two baffles 203, and are fixedly connected to the inner wall of the vent 1; wherein the servo motor 201 drives the fan blade 202 to rotate when working, and the fan blade 202 pushes the baffle 203 open with the hot air inside the converter box 3, and the hot air is discharged to the outside at the same time;

[0031] In the specific implementation process, it is worth pointing out that the model of the servo motor 201 is 28SMA-HB, the control panel 10 controls the servo motor 201 to work, the servo motor 201 drives the fan blades 202 to rotate, and the fan blades 202 push the baffle 203 when blowing air, and blow the heat inside the converter box 3 outward. When heat dissipation is not performed, the torsion spring 204 and the baffle 203 cooperate to seal the vent 1, thereby achieving waterproofing.

[0032] Specifically, based on the above-mentioned embodiment one, the control panel 10 controls the operation of the servo motor 201, and the servo motor 201 drives the fan blades 202 to rotate and blow air. The wind pushes the baffle 203 open, and at the same time the baffle 203 compresses the torsion spring 204, and the inside of the inverter box 3 is blown out. When the fan blades 202 stop working, the torsion spring 203 in a compressed state helps the baffle 203 to reset and prevent foreign matter from entering the vent 1.

[0033] Embodiment 3: By Figure 1 , 2As can be seen from Figure 4, the moisture-proof device 5 includes: an air inlet 501, which is provided in multiple numbers and is processed on one side of the air inlet pipe 4; a filter plate 502, which is installed inside the air inlet pipe 4; and a moisture-proof plate 503, which is installed inside the air inlet pipe 4. The external air enters the air inlet pipe 4 from the air inlet 501, and the air passes through the filter plate 502 to filter out impurities, and passes through the moisture-proof plate 503 to adsorb water vapor inside the air.

[0034] In the specific implementation process, it is worth pointing out that the mesh number of the filter plate 502 is not specifically limited, and it only needs to meet the use requirements. The moisture-proof plate 503 is filled with a desiccant. The main material of the desiccant is not limited, and it only needs to meet the use requirements. The desiccant can have a good adsorption effect on water vapor. The external air enters the air inlet 4 from the air inlet 501, and the filter plate 502 adsorbs the dust in the air, and the moisture-proof plate 503 adsorbs the water vapor in the air.

[0035] Specifically, based on the above-mentioned embodiment 1, external air enters the interior of the air intake pipe 4 through the air inlet 501. When the air passes through the filter plate 502, the dust in the air is adsorbed. When the air continues to move through the moisture-proof plate 503, the water vapor in the air is absorbed to prevent dust or water vapor in the air from entering the interior of the inverter case 3.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
