Description

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

The material is prior art and will not be described in detail here. A sealing piston 1006 is fixedly installed on the top surface of the heat-expanded airbag 1005, and the sealing piston 1006 is slidably arranged on the inner wall of the air pipe 1001; a piston rod 1007 is fixedly connected to the middle of the top surface of the sealing piston 1006, and a guide plate 1008 is fixedly connected to the inner wall of the air pipe 1001, and the piston rod 1007 is slidably arranged inside the guide plate 1008, and a touch head 1009 is fixedly installed on the top surface of the piston rod 1007, and a touch switch 1009 is fixedly installed on the inner wall of the top surface of the air pipe 1001 The touch switch 1010 is fixedly mounted on the top surface of the electrical cabinet 1. The touch head 1009 is arranged directly 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 mounted on the top surface of the electrical cabinet 1. A refrigeration compressor 1011 is fixedly mounted on the top surface of the heat dissipation frame 7. The output end of the refrigeration compressor 1011 is fixedly connected to a liquid inlet pipe 1012. A circulating pump 1013 is fixedly mounted on the outer wall of the heat dissipation frame 7. 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 1013. The output end of the 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 frame 7, and the condenser 1014 is arranged in a continuous S shape extending along the length direction of the heat dissipation frame 7.

[0031] Specifically, when air cooling is performed, the circulation pump 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 passage to improve the air 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 it is heated, so that the sealing piston 1006 slides upward along the inner wall of the air pipe 1001, and the piston rod 1007 drives the touch head 1009 to move upward, and the air in the air pipe 1001 is cooled.

If the degree of intelligence is higher, the refrigeration compressor 1011 here can also be electrically connected to the controller, when the temperature is high and the alarm alarms, while notifying the staff, the controller starts the refrigeration compressor 1011, and the refrigeration compressor 1011 works, and then the temperature is reduced; when the temperature drops to the required degree, the touch head 1009 is separated from the touch switch 1010, the signal connection is disconnected and sent to the controller, and the controller thereby releases the alarm of the alarm 11, and this process does not require the participation of the staff, and the overall degree of intelligence will be higher; the alarm 11 is also retained here, the purpose is that when the temperature cannot be reduced for a long time, the alarm 11 will continue to alarm, so that the staff can be notified to intervene manually, and the cooling effect can be better guaranteed.

[0033] Working principle: The heat insulation sleeve 3 and the water storage tank 4 are pre-buried in the ground to reduce the impact of high temperature. A drainage pipeline is laid in the ground. During the use of the electrical cabinet 1, the circulation pump 602 is started, and the water outlet pipe 601 draws out the water in the water storage tank 4. The water in the water storage tank 4 flows to the return pipe 604 through the shunt 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 storage 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 storage 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. On rainy days, rain 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 screen 618. , and then enters the interior of the water storage tank 4 through the water delivery pipe 620, and the excess water overflows through the overflow hole 5 to achieve automatic water filling. When air cooling and heat dissipation, the circulation pump 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 and heat dissipation effect. When the temperature in the electrical cabinet 1 is still high after water cooling and air cooling and heat dissipation, the heat expansion airbag 1005 expands upward when it is heated, so that the sealing piston 1006 slides upward along the inner wall of the air delivery 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 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 in the electrical cabinet 1 is quickly reduced to avoid the components in the electrical cabinet 1 from burning due to high temperature, thereby ensuring safety in use.
