Description

Technical Field

[0001] The utility model belongs to the technical field of network data rooms, and in particular relates to a dynamic power compensation control cabinet for power quality management. Background Art

[0002] With the rapid development of cloud computing services, the scale of cloud data centers has gradually increased. The electronic equipment in the data center room generates a lot of heat, which increases the temperature inside the data center room. To ensure that the electronic equipment operates normally at the appropriate temperature, this heat needs to be efficiently transported away.

[0003] Currently, the preferred cooling solution for data center operations is a combination of traditional air conditioning and natural cooling. To achieve this, a control cabinet is installed within the room. By controlling relays, gateway communication modules, and inverters, and integrating with the control software backend (platform), this collaboratively controls the natural cooling and air conditioning modes, achieving optimal energy conservation and reducing consumption. The control cabinet and platform also utilize energy consumption data collected from smart water and electricity meters outside the room, as well as temperature and humidity data collected within the room, to formulate comprehensive intelligent control strategies.

[0004] In the aforementioned system, since air conditioners, like inductive loads, cannot always operate at full capacity, their power factor is low, requiring power compensation. Existing systems install power compensation equipment at the transformer end, at least tens of meters outside the computer room. This approach primarily compensates for line losses caused by long front-end lines and only addresses low power factors near the transformer. Power compensation cannot be adjusted for equipment further away from the transformer, particularly for air conditioners within the computer room. Utility Model Content

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0025] like Figure 1 As shown, a power quality management dynamic power compensation control cabinet of the present invention includes a cabinet body 1 and a plurality of air switches 20, a gateway device 21, a remote control switch 22 and a plurality of contactors 23 placed in the cabinet body 1;

[0026] The cabinet 1 has an inlet and an outlet for cables to pass through on its side, and can be fixed to the wall by fasteners such as hexagon socket screws. The cabinet 1 plays a role in supporting and / or protecting internal components.

[0027] The air switch 20 provides protection for the corresponding powered peripherals against short circuit, leakage and overload.

[0028] The gateway device 21 is data linked to the backend platform. Specifically, they communicate with each other using the RS-485 serial bus standard.

[0029] The remote control switch 22 is electrically connected to the gateway device 21 and is used to control the power supply status of the gateway device 21. The remote control switch 22 establishes a link with the communication terminal through wireless communication technology.

[0030] Inductive loads have lower power factors, while capacitive loads have higher power factors. Inductive loads have a gap in the current between each phase, which results in a lower power factor. Air conditioners are inductive loads.

[0031] Under normal circumstances, the power factor of the air conditioner in the computer room is generally between 0.6-0.8. After adding the power compensator, the power factor in the circuit system can reach 0.9-0.95.

[0032] Power compensation is adopted at the nearest power supply end of the air conditioner. Specifically, a power compensator is added to the control cabinet of the computer room. According to the actual power factor of the air conditioner, different power / quantity compensators are inserted for compensation.

[0033] The original transformer (generally within 50m) remotely adjusted the entire circuit, and the power factor compensator was integrated into the air-conditioning room control cabinet to achieve local compensation and adjustment of the room air conditioner, solving the problem of the air conditioner not being able to operate at full load, resulting in low power factor.

[0034] A plurality of power compensators are arranged in the cabinet and connected to the corresponding contactors and gateway devices.

[0035] Arrange three or four groups of power compensators, and put different numbers of power compensators into use according to different detected time periods.

[0036] This embodiment uses four groups of power compensators of different models, such as 100 type 22A, 100 type 28A, 200 type 22A, and 300 type 40A, which are installed in the cabinet.

[0037] This power compensator is integrated in the control cabinet and dynamically adjusts and compensates the power of the circuit system according to the power collected by the meter. The power factor of the air-conditioning equipment circuit is compensated in a targeted manner, so that the power consumption of the circuit system can be controlled and saved.

[0038] The gateway device 21 is provided with a booster antenna.

[0039] The remote control switch 22 can restart the gateway device 21 when it crashes, so as to reconnect the gateway device 21 to the network.

[0040] After the gateway freezes (e.g. due to overheating), it cannot connect to the Internet and needs to be powered off and restarted to restart the network program. By observing the data platform at the back, if it is found that no data is uploaded or no data changes within a few minutes, it is judged that there is a network failure. According to experience, the gateway needs to be restarted. By remotely controlling the on and off of the remote control switch 22, the switch state of the gateway device 21 is switched, so that the network communication failure can be restored. There is no need for maintenance personnel to go to the computer room to manually power off and restart the corresponding equipment, which greatly improves the work efficiency of maintenance personnel, reduces maintenance response time, and reduces the maintenance and operating costs of the computer room.

[0041] The remote control method can be controlled through a built-in APP in a mobile phone terminal, and its remote wireless communication method includes but is not limited to the fourth generation mobile communication technology.

[0042] The contactor 23 is electrically connected to the gateway device 21 and the air switch 20 , and each contactor 23 controls a corresponding power-consuming peripheral device.

[0043] The back-end data platform collects data such as temperature, humidity, and power factors in the circuit system, compares them with the database, analyzes their changes, intelligently executes decision-making plans, controls relays, and turns on related equipment such as fans, air conditioners, air valves, and natural cooling sources in the computer room to jointly adjust the temperature and humidity in the computer room.

[0044] The gateway device is connected to the backend, and the backend detects the value of the system power factor. When compensation is required, at least one corresponding group of power compensators is operated to compensate for the air conditioning power factor.

[0045] The control cabinet is further provided with a power adapter 24 , which is used to provide an operating voltage to the gateway device 21 and is electrically connected to the remote control switch 22 .

[0046] A guide rail (not shown) is provided in the control cabinet, and the air switch 20 and the remote control switch 22 are installed on the guide rail.

[0047] The cabinet 1 is further provided with a plurality of connection terminals 25 , which can be specifically divided into strong current and weak current connection terminals 25 , through which external cables are connected to corresponding components in the cabinet 1 .

[0048] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
