Description

Technical Field

[0001] This invention relates to the field of control cabinets, and more particularly to a high-voltage solid-state soft-start control cabinet. Background Technology

[0002] A high-voltage soft starter is a starting device for high-voltage AC motors. It consists of a three-phase parallel thyristor assembly and its electronic control unit connected between the power supply and the controlled motor. A high-voltage solid-state soft starter is composed of multiple thyristors connected in series and parallel. By controlling the firing angle of the thyristors, the output voltage is controlled, which can meet the different voltage and current requirements during motor starting. During motor startup, the high-voltage solid-state soft starter cabinet increases the motor's terminal voltage according to a pre-set startup curve, enabling the motor to accelerate smoothly and thus reducing the electrical and mechanical impact of motor startup on the power grid, the motor, and connected equipment.

[0003] Existing high-voltage solid-state soft starter control cabinets require cable connections during use. However, since the inlet and outlet ports of the control cabinet are located at the bottom of the cabinet and lack protection, the cable inlet and outlet areas are more susceptible to humidity when the external humidity is high, resulting in poor performance and potential safety hazards. Summary of the Invention

[0004] This invention addresses the technical problem in existing control cabinets where both the inlet and outlet ports are located at the bottom of the cabinet and lack protection. As a result, when the external humidity is high, the cable inlet and outlet areas are more susceptible to the effects of humidity, which can easily lead to safety hazards. This invention provides a high-voltage solid-state soft-start control cabinet.

The top of the mounting plate base is provided with multiple cable holes, and the bottom of the control cabinet body is provided with multiple mounting holes. A cable protection module is provided at the bottom of the mounting plate base, and a heat dissipation auxiliary module is provided on one outer wall of the control cabinet body.

[0011] By incorporating a cable protection module, the cable protection module can protect the cables during use, isolating the cable connection ends from the bottom of the control cabinet. This reduces the impact of high humidity at the bottom of the control cabinet on the cables, thereby increasing the cable's lifespan and safety. Furthermore, the cable protection module can also fix the cable position during use, ensuring a neat and orderly cable distribution and preventing cable chaos, thus further enhancing the device's effectiveness.

[0016] By incorporating a heat dissipation auxiliary module, the control cabinet body can be assisted in heat dissipation during operation, thereby increasing the heat dissipation effect of the control cabinet body and avoiding insufficient natural heat dissipation. This enhances the effectiveness of the device. After heat dissipation, the device can re-export the cooled gas into the control cabinet, allowing the cooled gas to further cool the internal equipment of the control cabinet body, thereby further increasing the heat dissipation effect of the device.

[0017] As can be seen from the above, the high-voltage solid-state soft starter control cabinet provided by the present invention has the function of increasing safety during use. When in use, the device can protect the cables of the high-voltage solid-state soft starter control cabinet, reduce the impact of moisture on the cables, thereby avoiding safety hazards to the cables and increasing the effectiveness of the device.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] The high-voltage solid-state soft-start control cabinet disclosed in this invention is mainly used in control cabinets where the inlet and outlet ports are located at the bottom of the cabinet and lack protection. Therefore, when the external humidity is high, the inlet and outlet areas of the cables are more susceptible to the influence of humidity, which may lead to safety hazards.

[0024] Reference Figures 1-7 A high-voltage solid-state soft start control cabinet includes a control cabinet body 1. Two cabinet doors 2 are provided on one outer wall of the control cabinet body 1, and a mounting plate base 4 is fixedly connected to the inner wall of the control cabinet body 1. Multiple cable holes 6 are opened on the top of the mounting plate base 4, and multiple mounting holes are opened on the bottom of the control cabinet body 1. A cable protection module 5 is provided on the bottom of the mounting plate base 4, and a heat dissipation auxiliary module 3 is provided on one outer wall of the control cabinet body 1. The cable protection module 5 includes multiple protective sleeves 502, which pass through the interior of multiple mounting holes, and the top of each of the multiple protective sleeves 502 is fixedly connected to a protective sleeve base 504. The heat dissipation auxiliary module 3 includes a heat dissipation chamber 307, which is fixedly connected to one side of the outer wall of the control cabinet body 1. Four fixing ports are equally spaced on one side of the outer wall of the heat dissipation chamber 307, and the inner walls of the four fixing ports are provided with heat dissipation fin groups 302. Specifically, the cable hole 6 and the mounting hole are used for cable installation; the cable protection module 5 protects the cable from excessive external humidity, thereby increasing the safety of the cable and meeting the equipment's operating requirements; the heat dissipation auxiliary module 3 allows hot air from inside the device to enter and exit the heat dissipation chamber 307 to dissipate heat and increase the device's heat dissipation effect. At the same time, the device can transport the dissipated air back into the control cabinet body 1 to further assist in heat dissipation and meet the equipment's operating requirements.

[0025] Reference Figures 2-5 In a preferred embodiment, the cable protection module 5 further includes a fixed base 501, which is fixedly connected to the bottom of the inner wall of the control cabinet body 1. A connecting chamber 503 and a negative pressure pump 508 are fixedly connected to the fixed base 501, and a connecting pipe 505 is fixedly connected to the input end of the negative pressure pump 508. The input end of the connecting pipe 505 communicates with the interior of the connecting chamber 503. A plurality of conveying pipes 515 are fixedly connected to the top of the connecting chamber 503. A control valve 506 is provided on the outer wall of each of the plurality of conveying pipes 515, and an annular pipe 507 is fixedly connected to the input end of each of the plurality of conveying pipes 515. The plurality of annular pipes 507 are located outside the plurality of movable sleeves. Each of the plurality of protective sleeves 504 has three mounting ports. The top of each of the plurality of protective sleeves 504 contacts the bottom of the mounting plate 4, and three negative pressure pipes 510 are fixedly connected to the outer wall of each of the plurality of annular pipes 507. A fixed suction cup 509 is fixedly connected to the input end of each of the plurality of negative pressure pipes 510. The outer walls of multiple fixed suction cups 509 are respectively fixedly connected to the inner walls of multiple mounting ports, and multiple adjusting seats 512 are fixedly connected to the bottom of the inner wall of the control cabinet body 1. Multiple protective sleeves 502 pass through the interior of multiple adjusting seats 512 respectively, and the outer walls of multiple protective sleeves 502 are provided with pad rings 514. The outer walls of multiple adjusting seats 512 are connected to adjusting kits 511 by threads, and the bottom ends of multiple protective sleeves 502 are provided with four fixing holes. The bottom of the control cabinet body 1 is provided with multiple threaded holes, and the multiple fixing holes are respectively connected to the multiple threaded holes. The inner walls of each connected fixing hole and threaded hole are provided with the same fixing bolt 513.

[0026] Specifically, during cable installation, the cable is placed inside the protective sleeve 502 and the protective base 504, passing through the cable hole 6 and entering the top of the mounting plate 4 to connect it to the equipment. Then, the protective base 504 is moved, causing the fixed suction cup 509 to move and contact the mounting plate 4. Next, the negative pressure pump 508 is started, and the control valve 506 corresponding to the protective sleeve 504 is opened. At this time, the negative pressure pump 508 can open the connecting chamber 503. The internal gas is discharged, putting it into a negative pressure state. Then, through the delivery pipe 515, the annular pipe 507 and the negative pressure pipe 510, the fixed suction cup 509 is adsorbed and fixed to the bottom of the mounting plate base 4 to complete the installation. After that, the adjustment kit 511 is rotated. As the adjustment kit 511 descends, the adjustment seat 512 will gradually tighten and contact the pad ring 514, so that the adjustment seat 512 tightens and squeezes the protective sleeve 502 to further prevent humid air from entering the interior of the protective sleeve 502 through the bottom. In specific application scenarios, the cable protection module 5 is suitable for cable installation protection. That is, when in use, the cable protection module 5 can protect the cable, isolate the cable connection end from the bottom of the control cabinet, reduce the impact of high air humidity at the bottom of the control cabinet on the cable, thereby increasing the service life and safety of the cable. In addition, by protecting the cable, the position of the cable can also be fixed during use, thus ensuring that the cable distribution is neat and avoiding messy cable distribution, thereby further improving the effectiveness of the device.

[0027] Reference Figure 2 , Figure 6 and Figure 7In a preferred embodiment, the heat dissipation protection module further includes multiple exhaust pipes 301, each fixedly connected to one outer wall of the control cabinet body 1. The input ends of each exhaust pipe 301 are connected to the interior of the control cabinet body 1, and the output ends are connected to the interior of the heat dissipation chamber 307. Two air pump components 303 are fixedly connected to the bottom of the heat dissipation chamber 307. The output ends of each air pump component 303 are fixedly connected to two return pipes 304. Two fixing members 306 are fixedly connected to one inner wall of the control cabinet body 1, and the opposite outer walls of the two fixing members 306 are connected by a shaft. The same heat dissipation pipe 305 is connected to the heat dissipation pipe 305. The output ends of the four return pipes 304 are all connected to the interior of the heat dissipation pipe 305. The outer wall of the heat dissipation pipe 305 has multiple air ports 309. Two mounting parts 308 are fixedly connected to the outer wall of the heat dissipation pipe 305. The inner walls of the two mounting parts 308 are fixedly connected to the same mounting rod 310. A servo motor 313 is fixedly connected to the control cabinet body 1. The output end of the servo motor 313 is connected to a connecting plate 311 through a coupling. A movable part 312 is connected to the connecting plate 311 through a bearing. The inner wall of the movable part 312 is slidably connected to the outer wall of the mounting rod 310.

[0028] Specifically, during use, the air pump component 303 is activated, which discharges the gas inside the heat dissipation chamber 307, creating a negative pressure state. At this time, the heat dissipation chamber 307 draws in the rising hot air from inside the control cabinet through the exhaust pipe 301, and then passes through the heat dissipation fin assembly 302 for heat dissipation. After the heat dissipation, the gas is transported by the air pump component 303 to the return pipe 304, and further to the heat dissipation pipe 305. The heat dissipation gas is then ejected through the air port 309 on the heat dissipation pipe 305 to cool the equipment inside the control cabinet. Simultaneously, the servo motor 313 is activated, which drives the connecting plate 311 to rotate. This causes the connecting plate 311 to drive the movable part 312 to move back and forth on the mounting rod 310. As the movable part 312 moves, the mounting rod 310 causes the heat dissipation pipe 305 to shake, changing the blowing position of the heat dissipation gas and further increasing the heat dissipation effect. In specific application scenarios, the heat dissipation auxiliary module 3 is suitable for the operation and use of the control cabinet. When in use, the heat dissipation auxiliary module 3 can assist the control cabinet body 1 in heat dissipation, thereby increasing the heat dissipation effect of the control cabinet body 1 and avoiding the situation where its natural heat dissipation effect is insufficient, thus increasing the use effect of the device. After heat dissipation, the device can send the cooled gas back into the control cabinet, so that the cooled gas can cool down the internal equipment of the control cabinet body 1, thereby further increasing the heat dissipation effect of the device.

[0029] Working principle: When in use, the air pump component 303 is started, and the air pump component 303 discharges the gas inside the heat dissipation chamber 307, making it a negative pressure state. At this time, the heat dissipation chamber 307 will draw the hot air rising inside the control cabinet into its interior through the exhaust pipe 301, and then pass through the heat dissipation fin assembly 302 to dissipate the air. After the air is cooled, it can be delivered to the return pipe 304 through the air pump component 303, and then further delivered to the heat dissipation pipe 305. At this time, the cooled air can be sprayed out through the air port 309 on the heat dissipation pipe 305 to dissipate the heat dissipation of the equipment inside the control cabinet. At the same time, the servo motor 313 is started, and the servo motor 313 can drive the connecting plate 311 to rotate, which in turn causes the connecting plate 311 to drive the movable part 312 to move back and forth on the mounting rod 310. As the movable part 312 moves, the mounting rod 310 can drive the heat dissipation pipe 305 to shake, thereby changing the blowing position of the cooled air and further increasing the heat dissipation effect. During cable installation, the cable is placed inside the protective sleeve 502 and the protective base 504, and passes through the cable hole 6 into the top of the mounting plate 4 to connect it to the equipment. Then, the protective base 504 is moved, causing the fixed suction cup 509 to move and contact the mounting plate 4. The negative pressure pump 508 is then started, and the control valve 506 corresponding to the protective sleeve 504 is opened. At this time, the negative pressure pump 508 can discharge the gas inside the connecting chamber 503, putting it in a negative pressure state. Then, through the delivery pipe 515, the annular pipe 507, and the negative pressure pipe 510, the fixed suction cup 509 is attracted and fixed to the bottom of the mounting plate 4 to complete the installation. After that, the adjusting kit 511 is rotated. As the adjusting kit 511 descends, the adjusting seat 512 will gradually tighten and contact the pad ring 514, so that the adjusting seat 512 tightens and squeezes the protective sleeve 502 to further prevent humid air from entering the protective sleeve 502 through the bottom.
