Description

Technical Field

[0001] This invention relates to the field of temperature control technology, specifically to an online temperature control system and method for substations using infrared thermal imaging technology. Background Technology

[0002] A substation is a facility that changes voltage. To transmit electricity generated by a power plant to distant locations, the voltage must be increased to high voltage, and then reduced as needed near the user. This voltage adjustment process is performed by substations. The main equipment in a substation is switches and transformers. Depending on size, smaller substations are called substations, while larger substations are called transformer substations. A transformer substation generally refers to a step-down substation with a voltage level below 110kV; a transformer substation includes various voltage levels of both step-up and step-down substations. A substation is a power facility in a power system that transforms voltage, receives and distributes electrical energy, controls the flow of electricity, and adjusts voltage. It connects power grids of different voltage levels through its transformers. In specific environments, substations perform AC-DC-AC conversion processes, such as in submarine power transmission cables and long-distance transmission. Some substations use high-voltage direct current (HVDC) transmission. HVDC transmission overcomes the capacitive reactance losses of AC transmission, resulting in energy savings. The temperature around a substation needs to be controlled by a temperature control system.

[0003] Existing online temperature control systems for substations using infrared thermal imaging technology are prone to generating humid, hot air inside the cabinet during summer use due to alternating hot and cold temperatures. When the moisture accumulates into water droplets, it drips into the equipment, potentially damaging circuits and affecting the normal operation of electrical components inside the online temperature control cabinet. Furthermore, the system lacks a structure for timely and efficient dehumidification and cooling of the temperature control cabinet, indicating significant room for improvement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an online temperature control system and method for substations using infrared thermal imaging technology. This solves the problem that during summer use, the alternating hot and cold temperatures cause the cabinet's interior to accumulate damp, hot air.

[0006] Preferably, the front end of the online temperature control cabinet is provided with a support cover plate, and a number of buttons are evenly fixed on the front end of the support cover plate. The air inlet of the air pipe passes through the interior of the online temperature control cabinet, and the air outlet of the air pump is connected to the interior of the air inlet.

[0008] Preferably, a plurality of protrusions are evenly fixedly provided at the rear end of the scraper, a refrigeration device is fixedly provided at the lower left side of the insulation box, and a guide plate is fixedly provided between the front and rear walls of the inner cavity of the insulation box above the air inlet pipe, the guide plate being located below the condensation and ice scraping mechanism.

[0012] Preferably, the desiccant mechanism includes a rear cover plate, and a plurality of breathable clamps are uniformly fixedly arranged at the front end of the rear cover plate.

An infrared thermal imaging probe is fixedly arranged in the middle of the top of the online temperature control cabinet.

[0013] This invention also provides a method for online temperature control of substations using infrared thermal imaging technology, the specific method comprising the following steps:

[0014] Step 1, Cooling and Dehumidification: Start the air pump to draw the humid hot air from inside the temperature control cabinet into the insulation box through the suction pipe and the inlet pipe. The refrigeration unit controls the condenser plate to work, cooling the surface of the condenser plate and causing the temperature of the lower part of the insulation box to drop. When the humid hot air enters the insulation box, the temperature drops rapidly, turning into humid cold air. As it passes between several condenser plates, most of the moisture in the cold air will quickly condense into thin ice and adhere to the surface of the condenser plate. During this process, the cold air flows upward and blows towards the fins, driving the rotating wheel and shaft to rotate. This causes the scraper to rotate and scrape off the thin ice adhering to the surface of the condenser plate. The scraped-off thin ice falls to the bottom of the insulation box.

[0015] Step 2, Slowing down airflow and strong dehumidification: When the air pressure in the lower part of the insulation box is high enough, it will push the second air guide cap upward. The cold air, which has had most of its moisture removed, will be discharged through the second air outlet through the air guide end and continue to flow upward. It will pass through the breathable plate and desiccant. During the process, the small amount of moisture remaining in the cold air will be completely absorbed by the desiccant and become dry cold air. When the second air guide cap is pushed up again, the piston will be pushed up accordingly, so that the first air outlet is connected to the inside of the insulation box. The dry cold air will enter the air outlet pipe through the first air outlet and finally be blown back into the interior of the temperature online control cabinet through the exhaust pipe to cool down the components inside the temperature online control cabinet.

[0016] Step 3: Clean the ice: Periodically pull down the sealing plate with a certain amount of force to release the insulation box from the plug. As the rubber ring moves downward, it will scrape off the surrounding ice in time, thus removing the ice. After the ice is removed, restore the sealing plug mechanism to its original state.

[0017] Preferably, the plurality of rotating wheels and the plurality of condensing plates are interleaved, and the rubber ring is in contact with the lower inner wall of the insulation box.

[0038] This invention also provides a method for online temperature control of substations using infrared thermal imaging technology, the specific method including the following steps:

[0039] Step 1, Cooling and Dehumidification: Start the air pump 5 to draw the humid hot air inside the temperature online control cabinet 1 into the interior of the insulation box 71 through the suction pipe 4 and the inlet pipe 6. The refrigeration device 736 controls the condenser plate 731 to work, so that the surface of the condenser plate 731 is cooled down, which causes the temperature of the lower part of the inner cavity of the insulation box 71 to drop. When the humid hot air enters the insulation box 71, the temperature drops rapidly and becomes humid cold air. Then, when it passes between several condenser plates 731, most of the moisture in the cold air will quickly condense into thin ice and adhere to the surface of the condenser plate 731. During the process, the cold air flows upward and blows towards the fins 734, driving the rotating wheel 733 and the rotating shaft 732 to rotate, thereby causing the scraper 7352 to rotate and scrape off the thin ice adhering to the surface of the condenser plate 731. The scraped thin ice falls to the bottom of the inner cavity of the insulation box 71.

[0040] Step 2, Slowing down airflow and strong dehumidification: When the air pressure in the lower part of the inner cavity of the insulation box 71 is high enough, it will push the second air guide cap 774 upward. The cold air with most of the moisture removed will be discharged through the air guide end 771 and the second air outlet 775, and continue to flow upward. After passing through the breathable clamp 792 and the desiccant 793, the remaining small amount of moisture in the cold air will be completely absorbed by the desiccant 793 and become dry cold air. When the second air guide cap 774 is pushed up again, the piston 777 will be pushed up accordingly, so that the first air outlet 773 is connected to the inside of the insulation box 71. The dry cold air enters the air outlet pipe 8 through the first air outlet 773, and finally blows back into the interior of the temperature online control cabinet 1 through the exhaust pipe 9 to cool down the components inside the temperature online control cabinet 1.

[0041] Step 3: Cleaning ice slag: Periodically pull down the sealing plate 761 with a certain amount of force to release the locking of the insulation box 71 to the plug post 765. As the rubber ring 764 moves downward, it will scrape off the surrounding ice slag in time, thus removing the ice slag. After the ice slag is removed, restore the sealing plug mechanism 76 to its original state.

9. A method for online temperature control of a substation using infrared thermal imaging technology, characterized in that: The substation temperature online control system employing the infrared thermal imaging technology as described in claim 8 includes the following steps: Step 1, Cooling and Dehumidification: Start the air pump (5) to draw the humid hot air inside the temperature online control cabinet (1) into the interior of the insulation box (71) through the air intake pipe (4) and the air inlet pipe (6). The refrigeration device (736) controls the condenser plate (731) to work, so that the surface of the condenser plate (731) is cooled down, which causes the temperature of the lower part of the inner cavity of the insulation box (71) to drop. When the humid hot air enters the insulation box (71), the temperature drops rapidly and becomes humid cold air. Then, when it passes between several condenser plates (731), most of the moisture in the cold air will quickly condense into thin ice and adhere to the surface of the condenser plate (731). During the process, the cold air flows upward and blows towards the fins (734), which drives the rotating wheel (733) and the rotating shaft (732) to rotate, so that the scraper (7352) rotates to scrape off the thin ice adhering to the surface of the condenser plate (731). The scraped thin ice falls to the bottom of the inner cavity of the insulation box (71). Step 2, Slowing down the airflow and dehumidifying: When the air pressure in the lower part of the inner cavity of the heat preservation box (71) is large enough, the second air guide cap (774) will be pushed up. The cold air with most of the moisture removed will be discharged through the second air outlet (775) through the air guide end (771) and continue to flow upward. It will pass through the breathable clamp (792) and the desiccant (793). During the process, the remaining small amount of moisture in the cold air will be completely absorbed by the desiccant (793) and become dry cold air. When the second air guide cap (774) is pushed up again, the piston (777) will be pushed up accordingly, so that the first air outlet (773) is connected to the inside of the heat preservation box (71). The dry cold air enters the air outlet pipe (8) through the first air outlet (773) and finally blows back into the interior of the temperature online control cabinet (1) through the exhaust pipe (9) to cool down the components inside the temperature online control cabinet (1). Step 3: Cleaning ice slag: Periodically pull down the sealing plate (761) with a certain force to release the locking of the insulation box (71) to the plug post (765). As the rubber ring (764) moves down, it will scrape off the surrounding ice slag in time, thus removing the ice slag. After the ice slag is removed, restore the sealing plug mechanism (76) to its original state.

10. A substation temperature online control method using infrared thermal imaging technology according to claim 9, characterized in that: Several of the aforementioned rotating wheels (733) and several condensing plates (731) are interleaved, and the rubber ring (764) is in contact with the lower inner wall of the heat preservation box (71).
