[0002] High and low voltage complete electrical cabinets are also known as high and low voltage distribution cabinets. As the name implies, they are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led to low voltage distribution cabinets. The low voltage distribution cabinets are then led to various power distribution boards, control boxes, and switch boxes. The equipment in them is a distribution device that meets the design functional requirements by assembling some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices into one.

[0003] Existing high and low voltage complete electrical cabinets mostly use fans for heat dissipation. When used in high temperature environments in summer, the heat dissipation effect of fans alone is poor. High and low voltage complete electrical cabinets are in high temperature environments for a long time, and the electrical components inside them are easily burned due to high temperature, which in turn causes fires and poses a safety hazard.

In an embodiment of the present invention, the specific form of the toothless gear 606 can be: a complete gear is missing half a tooth, and the missing half of the tooth is divided into two parts, and each quarter is arranged at an interval with the remaining two quarters of the toothed parts; this is one arrangement form, and the size of the missing tooth can also be set according to actual needs.

[0028] There are two racks 607 meshing on the surface of the toothless gear 606, and the two racks 607 are distributed in a circular array around the toothless gear 606; one end of the rack 607 is fixedly connected to a spoiler 608, and the two spoilers 608 are distributed in a circular array around the toothless gear 606, and a number of array-distributed spoiler grooves 609 are provided inside the spoiler 608, and the spoiler 608 is movably arranged inside the water tank 4; the middle part of the outer wall of the side away from each other of the two racks 607 is fixedly connected to a guide seat 611, and a guide rod 610 is fixedly installed on the inner wall of the top surface of the water tank 4, and the guide seat 611 is slidably arranged on the surface of the guide rod 610, and the end of the rack 607 away from the spoiler 608 is fixedly connected to a spring 612, and the inner wall of the top surface of the water tank 4 is fixedly connected The fixing plate 613 and the end of the spring 612 away from the rack 607 are fixedly connected to the outer wall of the fixing plate 613; one end of the top surface of the electrical cabinet 1 is fixedly connected to the guide tube 614, and the top surface of the guide tube 614 is fixedly installed with a guide cover 615, and the outer wall of the guide tube 614 is fixedly connected to the positioning sleeve 616, and the interior of the positioning sleeve 616 is plugged with a guide sleeve 617, and a filter screen 618 is fixedly connected between the guide tube 614 and the guide sleeve 617. A plurality of water inlet holes 619 are opened on the outer wall of the guide tube 614, and the water inlet holes 619 are arranged between the positioning sleeve 616 and the filter screen 618. The water outlet of the guide tube 614 is fixedly connected to the water pipe 620, and the end of the water pipe 620 away from the guide tube 614 is fixedly connected to the water inlet of the water tank 4.

[0029] Specifically, when the electrical cabinet 1 is in use, the circulation pump 602 is started, the water outlet pipe 601 draws out the water in the water tank 4, and the water in the water tank 4 flows into the return pipe 604 through the shunt pipe 603, thereby realizing water cooling and heat dissipation of various components in the electrical cabinet 1. Finally, the water in the return pipe 604 flows back to the inside of the water tank 4, and the drive motor 605 is started at the same time. The drive motor 605 drives the toothless gear 606 to rotate, and the toothless gear 606 is meshed with the two racks 607 at the same time. When the rack 607 is separated from the teeth on the toothless gear 606, under the elastic action of the spring 612, the toothless gear 606 is rotated. , so that the rack 607 returns to its initial position, and this cycle repeats, causing the two spoilers 608 to reciprocate in opposite directions. After the water in the water tank 4 is disturbed by the spoiler 608 and the spoiler groove 609, the fluidity of the water is greatly increased, which accelerates the cooling speed of the water and improves the effect of water cooling and heat dissipation. On rainy days, rainwater drops on the guide cover 615 and the guide sleeve 617, and after being filtered by the filter screen 618, enters the guide tube 614 through the water inlet hole 619, and then enters the interior of the water tank 4 through the water pipe 620. Excess water overflows through the overflow hole 5, realizing automatic water filling.

[0030] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7In a preferred embodiment, the explosion-proof heat dissipation assembly 10 includes an air pipe 1001, which is fixedly connected to the inner wall of the electrical cabinet 1 through a bracket, and the top side wall of the air pipe 1001 is fixedly connected to the air storage pipe 1002, and the air pipe 1001 is provided with an air delivery hole 1003 connected to the air storage pipe 1002; the bottom inner wall of the air pipe 1001 is fixedly connected to a bottom bracket 1004, and the top surface of the bottom bracket 1004 is fixedly connected to a heat-expandable airbag 1005, which is made of a material that can be expanded by preheating. The top surface of the heat-expanded airbag 1005 is fixedly mounted with a sealing piston 1006, which is slidably arranged on the inner wall of the air pipe 1001; the middle part of the top surface of the sealing piston 1006 is fixedly connected with a piston rod 1007, and the inner wall of the air pipe 1001 is fixedly connected with a guide plate 1008, and the piston rod 1007 is slidably arranged inside the guide plate 1008, and the top surface of the piston rod 1007 is fixedly mounted with a touch head 1009, and the inner wall of the top surface of the air pipe 1001 is fixedly mounted with a touch switch The touch switch 1010 is closed, and the touch head 1009 is arranged just below the touch switch 1010. The output end of the touch switch 1010 is fixedly connected to the alarm 11 through a signal line. The alarm 11 is fixedly installed on the top surface of the electrical cabinet 1; the top surface of the heat dissipation frame 7 is fixedly installed with a refrigeration compressor 1011, and the output end of the refrigeration compressor 1011 is fixedly connected to a liquid inlet pipe 1012. The outer wall of the heat dissipation frame 7 is fixedly installed with a circulating pump 2 1013, and the end of the liquid inlet pipe 1012 away from the refrigeration compressor 1011 is fixedly connected to the input end of the circulating pump 2 1013. The output end of pump 2 1013 is fixedly connected to a condenser 1014, the interior of the condenser 1014 is filled with condensate, and the condenser 1014 is arranged in a continuous S shape inside the heat dissipation rack 7, and the condenser 1014 is arranged in a continuous S shape extending along the length direction of the heat dissipation rack 7. The condenser 1014 is arranged between the electrical cabinet 1 and the heat dissipation fan 9, and the end of the condenser 1014 away from the circulation pump 2 1013 is fixedly connected to the return liquid pipe 1015, and the end of the return liquid pipe 1015 away from the condenser 1014 is fixedly connected to the input end of the refrigeration compressor 1011.

[0031] Specifically, when cooling with air, the circulation pump 2 1013 is started, and the refrigeration compressor 1011, the liquid inlet pipe 1012, the condenser pipe 1014 and the liquid return pipe 1015 form a circulation path to improve the cooling effect. When the temperature in the electrical cabinet 1 is still high after water cooling and air cooling, the heat expansion airbag 1005 expands upward when heated, causing the sealing piston 1006 to slide upward along the inner wall of the gas pipe 1001, and the piston rod 1007 drives the touch head 1009 to move upward, and the gas in the gas pipe 1001 is cooled. The gas enters the interior of the gas storage pipe 1002 through the gas delivery hole 1003, and finally the touch head 1009 contacts the touch switch 1010, causing the alarm 11 to sound an alarm, prompting the staff to perform corresponding operations. At the same time, the refrigeration compressor 1011 is turned on, and the condensate flowing through is cooled by the refrigeration compressor 1011, so that the temperature of the airflow entering the electrical cabinet 1 is greatly reduced, and then the temperature inside the electrical cabinet 1 is quickly reduced, thereby preventing the components in the electrical cabinet 1 from burning due to high temperature and ensuring safety in use.

[0032] This process can also be controlled by a controller, that is, a controller is arranged, and the alarm 11 and the touch switch 1010 are electrically connected to the controller. The touch switch 1010 sends a signal to the controller, and the controller then sends a signal to the alarm 11, thereby controlling the alarm 11 to alarm, thereby reminding the corresponding staff, making the intelligent effect better. If the intelligent level is higher, the refrigeration compressor 1011 can also be electrically connected to the controller. When the temperature is high and the alarm sounds, while notifying the staff, the controller starts the refrigeration compressor 1011, and the refrigeration compressor 1011 works, thereby achieving cooling; when the temperature drops to the required degree, the touch head 1009 is separated from the touch switch 1010, disconnecting the signal connection and sending it to the controller, which then cancels the alarm 11. This process does not require the intervention of the staff, and the overall intelligent level will be higher; the alarm 11 is retained here, so that when the temperature cannot be cooled for a long time, the alarm 11 will continue to alarm, so that the staff can be notified to intervene manually, thereby better ensuring the cooling effect.

[0033] Working principle: The heat insulation sleeve 3 and the water tank 4 are pre-buried in the ground to reduce the impact of high temperature. A drainage pipeline is laid in the ground. When the electrical cabinet 1 is in use, the circulation pump 602 is started, and the outlet pipe 601 draws out the water in the water tank 4. The water in the water tank 4 flows to the return pipe 604 through the diversion pipe 603, realizing water cooling of various components in the electrical cabinet 1. Finally, the water in the return pipe 604 flows back to the inside of the water tank 4, and the drive motor 605 is started at the same time. The drive motor 605 drives the toothed gear 606 to rotate, and the toothed gear 606 and the two racks 607 meshes at the same time. When the rack 607 is separated from the teeth on the toothless gear 606, the rack 607 returns to its initial position under the elastic action of the spring 612. This cycle repeats, causing the two spoilers 608 to reciprocate in opposite directions. After the water in the water tank 4 is disturbed by the spoiler 608 and the spoiler groove 609, the fluidity of the water is greatly increased, which speeds up the cooling speed of the water and improves the effect of water cooling and heat dissipation. On rainy days, rainwater drops on the guide cover 615 and the guide sleeve 617, and enters the guide tube 614 through the water inlet hole 619 after being filtered by the filter 618. , and then enters the interior of the water storage tank 4 through the water pipe 620, and the excess water overflows through the overflow hole 5 to achieve automatic water filling. When the air cooling heat dissipation is carried out, the circulation pump 2 1013 is started, and the refrigeration compressor 1011, the liquid inlet pipe 1012, the condenser pipe 1014 and the return liquid pipe 1015 form a circulation passage to improve the air cooling heat dissipation effect. When the temperature in the electrical cabinet 1 is still high after water cooling and air cooling heat dissipation, the heat expansion airbag 1005 expands upward when heated, causing the sealing piston 1006 to slide upward along the inner wall of the air pipe 1001, and the piston rod 1007 drives the touch The head 1009 moves upward, and the gas in the gas pipe 1001 enters the interior of the gas storage pipe 1002 through the gas hole 1003. Finally, the touch head 1009 contacts the touch switch 1010, causing the alarm 11 to sound an alarm, prompting the staff to perform corresponding operations. At the same time, the refrigeration compressor 1011 is turned on, and the refrigeration compressor 1011 is used to cool the condensate flowing through, so that the temperature of the airflow entering the electrical cabinet 1 is greatly reduced, and then the temperature inside the electrical cabinet 1 is quickly reduced to prevent the components in the electrical cabinet 1 from burning due to high temperature, thereby ensuring safety in use.
