Description

Technical Field

[0001] This invention relates to the field of transformer cooler technology, specifically to a high-altitude-adaptive intelligent heat dissipation cooler control cabinet. Background Technology

[0002] High-altitude areas are characterized by low air pressure, thin air, large temperature differences between day and night, and harsh environments, which place more stringent requirements on the performance of control cabinets.

[0003] Conventional cooler control cabinets have the following technical defects: 1. Poor heat dissipation adaptability of air conditioning components: The heat dissipation structure of the air conditioning components in conventional control cabinets is not optimized for high-altitude and low-pressure environments. The inlet and outlet air isolation design is poor, and the mixing of hot and cold airflows leads to a significant reduction in air conditioning heat dissipation efficiency. Electrical components inside the cabinet frequently fail due to high temperatures. 2. Limited monitoring dimensions: Relying solely on manual inspections, it is impossible to monitor the ambient temperature inside the cabinet, the temperature of critical component locations, fire hazards (smoke), and the cooler operating current in real time. Abnormal situations are detected late, and manual inspections in high-altitude areas are costly and difficult. 3. Incomplete control and alarm mechanisms: It can only realize the start and stop control of the cooler and cannot adaptively adjust the heat dissipation capacity according to the operating conditions inside the cabinet. When abnormalities occur, it lacks timely local alarm and remote feedback functions, resulting in low equipment operation safety.

[0004] Therefore, there is an urgent need for a cooler control cabinet that is adapted to high-altitude environments, has an optimized heat dissipation structure, and integrates multi-dimensional intelligent monitoring to solve the above problems. Summary of the Invention

[0022] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0023] This invention discloses a high-altitude-adaptive intelligent heat dissipation cooler control cabinet, with reference to... Figures 1-8 The system includes a cabinet 1, within which are housed an air conditioning unit 3, a cooler, a cooler control module 2, an air conditioning heat dissipation optimization mechanism, a multi-dimensional monitoring module, an intelligent monitoring host 15, and an alarm communication module. The cooler's power supply circuit is connected to the cooler control module 2 for start-stop control. In one embodiment, the cabinet 1 is constructed from 2.5mm thick cold-rolled steel plate, with the surface treated with powder coating for corrosion protection, suitable for high-altitude, humid, and high-UV environments. The cabinet dimensions are 1800mm × 800mm × 600mm, and the air conditioning unit 3 is embedded in the back of the cabinet.

[0024] The air inlet 5 and air outlet 6 of the air conditioning component 3 are located on the cabinet 1, and a longitudinal isolation plate 4 is provided between the air inlet 5 and the air outlet 6. The longitudinal isolation plate 4 is made of insulation cotton. In one embodiment, the air inlet 5 is located on the lower left side of the cabinet, and the air outlet 6 is located on the upper right side of the cabinet. The isolation plate 4 is fixed to the inside of the cabinet with four M8 bolts to physically isolate the air inlet 5 and the air outlet 6, avoiding the mixing and interference of hot and cold airflows, and adapting to the heat dissipation requirements under high altitude and low air pressure.

[0025] A dust filter 7 is installed at the air inlet 5. The dust filter 7 is connected to the cabinet 1 in a detachable manner (bolts, screws, or grooves and protrusions, etc.).

[0026] An adjustable hinged cooling mechanism is installed at each of the six air outlets. This mechanism includes hinged fins 8, a stepper motor 9, a transmission link 10, and a rotating shaft. Each hinged fin 8 is hinged to the frame of the air outlet 6 via the rotating shaft. The stepper motor 9 is fixed to the outer wall of the cabinet 1 via a bracket. The output shaft of the stepper motor 9 is linked to the rotating shaft of each hinged fin 8 via the transmission link 10, driving the hinged fins 8 to rotate around the rotating shaft, achieving stepless adjustment of the opening degree from 0-90°. Under normal conditions, the opening degree of the hinged fins 8 is between 30° and 45°. In one embodiment, the hinge fins 8 are made of 304 stainless steel, and there are 7 fins, each fin is 60cm long and 8cm wide. The shaft is made of brass. The stepper motor 9 is model 28BYJ-48 with a power of 8W. It is fixed to the outside of the right side of the cabinet by an L-shaped bracket. The transmission connecting rod 10 is made of aluminum alloy, and its two ends are connected to the output shaft of the stepper motor and the hinge fin shaft by couplings to achieve synchronous drive.

[0027] The multi-dimensional monitoring module includes an ambient temperature sensor 11, a fiber optic temperature sensor 12, a smoke sensor 13, and a three-phase current monitoring system. The ambient temperature sensor 11 is installed in the densely packed component area of ​​the middle layer inside the cabinet 1 to collect the overall ambient temperature within the cabinet 1. The fiber optic temperature sensor 12 is used to monitor the temperature of key components in the cooler (contactors, circuit breaker terminals, etc.), for example, the fiber optic temperature sensor 12 is attached to the surface of the contactor's main contacts. The smoke sensing system 13 is fixed to the center of the top of the cabinet with expansion screws to monitor the smoke concentration inside the cabinet. The three-phase current monitoring system is connected in series in the three-phase power supply circuit of the cooler. Specifically, the three current sensors of the three-phase current monitoring system 14 are connected in series on the A, B, and C phase power supply cables of the cooler to monitor the cooler's operating current.

[0028] The output terminals of each sensor in the multi-dimensional monitoring module are connected to the input terminals of the intelligent monitoring host 15. The output terminals of the intelligent monitoring host 15 are connected to the input terminals of the adjustable hinged heat dissipation mechanism, the cooler control module 2, and the alarm communication module. The intelligent monitoring host 15 is equipped with a RS485 communication module for establishing a signal connection with the remote back-end management system to achieve data upload. In one embodiment, the intelligent monitoring host 15 is mounted on the electrical mounting plate on the top of the cabinet via a standard guide rail. Its signal input terminals are connected to the signal lines of each sensor via an RS485 bus. The control output terminals are connected to the stepper motor 9, the air conditioning component 3, the cooler control module 2, the buzzer 16, and the LED warning light 17 via 2.5mm² copper core wires, respectively. The wireless communication module 18 is integrated inside the intelligent monitoring host and communicates with the remote back-end via a 4G network.

[0029] An ambient temperature sensor (model PT100, measurement range -40℃~70℃) is installed in the densely populated component area inside the cabinet using clips. A fiber optic temperature sensor (measurement accuracy ±0.5℃) is attached to the surface of core components of the cooler control module (such as contactor and circuit breaker terminals) using high-temperature tape to monitor the temperature at critical locations. A smoke detection system (response time no greater than 5 seconds) is fixedly installed on the side of the cabinet near the air conditioning compartment outlet to detect smoke concentration inside the cabinet and provide early warning of fire hazards. A three-phase current monitoring system for the cooler (using an integrated open-type three-phase current sensor, measurement range 0~25A) is connected in series in the three-phase power supply circuit of the cooler to monitor the cooler's operating current in real time.

[0030] The intelligent monitoring host 15 receives monitoring data from the multi-dimensional monitoring module in real time and performs comprehensive analysis. Specifically, for the ambient temperature sensor 11 and the fiber optic temperature sensor 12, when the ambient temperature sensor 11 detects a temperature greater than the first preset threshold or the fiber optic temperature sensor 12 detects a temperature at a key location of the element greater than the second preset threshold, the intelligent monitoring host 15 outputs a command: controlling the stepper motor 9 to drive the hinged fins 8 to increase the opening and closing degree, and simultaneously controlling the air conditioning component 3 to increase the cooling power.

[0031] For smoke sensor 13, when smoke sensor 13 detects that the smoke concentration is greater than the third preset threshold, intelligent monitoring host 15 controls the hinge fins 8 to fully open and triggers the alarm communication module.

[0032] For the three-phase current monitoring system, when the three-phase current monitoring system detects an abnormal current in the cooler, the intelligent monitoring host 15 triggers an alarm and uploads the abnormal current data, while simultaneously outputting a command to the cooler control module 2 to shut down the cooler.

[0033] In one embodiment, when the ambient temperature sensor detects a temperature > 45°C (preset value, which can be adjusted on-site according to actual conditions), or when the fiber optic temperature sensor detects a temperature > 90°C at a critical location of the element (preset value, which can be adjusted on-site according to actual conditions), the intelligent monitoring host outputs a command: controls the stepper motor to drive the hinged fins to increase the opening and closing degree to 80°~90°, and simultaneously links the air conditioning components to increase the cooling power and enhance the heat dissipation effect. When the smoke sensor detects a smoke concentration > 0.1 mg / m³ (preset value, which can be adjusted on-site), the intelligent monitoring host controls the hinged fins to fully open (90°), triggering a buzzer and LED warning light to continuously alarm, and uploads the abnormal information (including smoke concentration, real-time temperature, and equipment number) to the monitoring backend through the communication module. When the three-phase current monitoring system detects an abnormal current in the cooler (>2 times the rated current), the intelligent monitoring host triggers an alarm and uploads the abnormal current data. At the same time, it can link the cooler control module to shut down the cooler according to the preset logic to avoid equipment damage. Under normal operating conditions, the hinge fins maintain an opening angle of 30°~45° to balance heat dissipation, dust prevention, and heat preservation requirements.

[0034] When applied in an area at an altitude of 4500m, when the ambient temperature sensor 11 detects that the temperature inside the cabinet reaches 48℃, the intelligent monitoring host 15 instructs the stepper motor 9 to drive the hinged fins 8 to rotate to 70°, and the cooling power of the air conditioning component 3 is increased to 80%. When the fiber optic temperature sensor 12 detects that the contactor temperature reaches 92℃, the hinged fins 8 are fully opened to 90°, the buzzer 16 and the LED warning light 17 are activated, and the background receives a real-time overheat warning for the components. When the smoke sensing system 13 detects a smoke concentration of 0.15mg / m³, the background receives a fire hazard alarm, and the staff can remotely command the cooler to be shut down.

[0035] This invention discloses a high-altitude-adaptive intelligent heat dissipation and cooling control cabinet. When the transformer is running, a multi-dimensional monitoring module collects real-time data on ambient temperature, cabinet temperature, temperatures of key transformer components, and three-phase current, transmitting this data to the intelligent monitoring host 15. The intelligent monitoring host 15 analyzes and processes the received data, determining the normal operating status of the equipment based on a preset control strategy. If the equipment is operating normally, the intelligent monitoring host 15 automatically adjusts the cooling capacity of the air conditioning component 3 and the operating mode of the cooler according to the cabinet temperature and ambient temperature, maintaining the cabinet temperature within a suitable range. Simultaneously, the air conditioning heat dissipation optimization mechanism automatically adjusts the opening and direction of the air ducts based on the air conditioning cooling capacity and the cabinet temperature distribution, ensuring even distribution of cool air throughout the cabinet and improving heat dissipation. The adjustable hinged heat dissipation mechanism at the air outlet 6 automatically adjusts the hinge angle according to the cabinet temperature and airflow, further optimizing the heat dissipation effect.

[0036] If the multi-dimensional monitoring module detects an abnormality in the equipment, such as excessively high temperature, abnormal current, or smoke, the intelligent monitoring host 15 will immediately issue an alarm signal and send the alarm information to the mobile phone of the maintenance personnel via the alarm communication module. Simultaneously, the cooler control module 2 will automatically adjust the cooler's operating mode according to the fault type and take corresponding protective measures, such as increasing the cooler's heat dissipation power or stopping the transformer operation, to prevent the fault from escalating and ensure the safe operation of the equipment. This control cabinet is used in power facilities such as substations, power plants, and transmission lines in high-altitude areas, providing reliable heat dissipation and intelligent monitoring services for critical equipment such as transformers. This can improve the operational reliability and safety of the power system and ensure power supply in high-altitude areas.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the technical solution of the present invention in any way. Those skilled in the art should understand that, without departing from the spirit and principles of the present invention, the technical solution can be modified and replaced in several simple ways, and these modifications and replacements are all within the scope of protection covered by the claims.
