Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an intelligent power distribution cabinet with global temperature measurement and zoned temperature control. Background Technology

[0002] A distribution cabinet is an electrical device used to distribute electrical energy and control electrical equipment. Its main functions are centralized control, protection, and distribution of electrical energy.

[0003] According to statistics, insulation faults and temperature rise faults account for more than 50% of switchgear accidents in my country's power system. If these faults are not detected and dealt with in time, they can easily cause major accidents such as fires and power outages.

[0004] While existing power distribution functions are becoming increasingly sophisticated, ventilation systems are typically quite basic and generally employ a global temperature control strategy, lacking single-point temperature control capabilities. This results in low temperature control efficiency and difficulty in quickly responding to sudden emergencies. Utility Model Content

[0005] To address the aforementioned issues, this invention provides an intelligent power distribution cabinet with global temperature measurement and zoned temperature control. This cabinet can employ different temperature measurement and control strategies for different zones within the power distribution cabinet and can also achieve rapid temperature control for a single zone.

[0006] A smart power distribution cabinet with global temperature measurement and zoned temperature control includes a cabinet body, a temperature measuring device, and a temperature control device. The cabinet body has a door on one side and several zones inside the cabinet body. The zones are separated by partitions. Each zone is equipped with a temperature measuring device. The temperature control device includes a fresh air duct and an exhaust air duct. The fresh air duct is located at the lower end of the cabinet body, and the exhaust air duct is located at the upper end of the cabinet body.

[0007] Furthermore, the cabinet is divided into three sections: the busbar section, the contact section, and the capacitor section.

[0008] Furthermore, the temperature measuring device includes an RFID temperature measuring component, a fiber optic temperature measuring component, and an infrared spectral thermal imaging component. The RFID temperature measuring component is located in the busbar partition, the fiber optic temperature measuring component is located in the contact partition, and the infrared spectral thermal imaging component is located in the capacitor partition.

[0009] Furthermore, the busbar section and the contact section are separated by a first partition, and the contact section and the capacitor section are separated by a second partition.

[0010] Furthermore, both the fresh air duct and the exhaust duct include a fan and a distribution pipe. The fan is installed on the cabinet door, and the distribution pipe has three air ducts: one air duct is connected to the busbar zone, one air duct is connected to the contact zone, and the other air duct is connected to the capacitor zone.

[0011] Furthermore, a distribution plate and a drive motor are provided between the distribution pipe and the fan. The bottom of the drive motor is mounted on the fan, and the drive motor shaft is connected to the middle of the distribution plate to drive the distribution plate to rotate. A ventilation hole is provided on the distribution plate.

[0012] Furthermore, the first partition is provided with a first through hole, which is connected to one air duct of the distribution pipe, and the second partition is provided with a second through hole, which is connected to the other air duct of the distribution pipe.

[0013] The advantages of this utility model are:

[0014] Because the optimal operating temperature and heat dissipation rate of different functional modules in the distribution cabinet are different, three different temperature measurement strategies are adopted for the three main functional modules (busbar zone, contact zone, and capacitor zone).

[0015] At the same time, independent temperature control strategies are adopted for the three zones. If the temperature rise of a single zone is abnormal, the temperature control device can control the temperature of that zone separately. Moreover, because the air flows faster when the temperature is controlled separately, the effect of rapid temperature control can be achieved. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A smart power distribution cabinet with global temperature measurement and zoned temperature control includes a cabinet body, temperature measuring devices, and temperature control devices. The cabinet body has a door on one side and several zones within it, separated by partitions. Each zone contains a temperature measuring device. The temperature control device includes a fresh air duct and an exhaust air duct; the fresh air duct is located at the bottom of the cabinet, and the exhaust air duct is located at the top. The cabinet body has three zones: a busbar zone, a contact zone, and a capacitor zone. The temperature measuring devices include an RFID temperature measuring component, a fiber optic temperature measuring component, and an infrared spectral thermal imaging component. The RFID temperature measuring component is located in the busbar zone, the fiber optic temperature measuring component in the contact zone, and the infrared spectral thermal imaging component in the capacitor zone. The busbar zone and the contact zone are separated by a first partition, and the contact zone and the capacitor zone are separated by a second partition. Both the fresh air duct and the exhaust duct include a fan and a distribution pipe. The fan is mounted on the cabinet door. The distribution pipe has three air ducts: one connects to the busbar zone, one connects to the contact zone, and the other connects to the capacitor zone. A distribution panel and a drive motor are located between the distribution pipe and the fan. The bottom of the drive motor is mounted on the fan, and the drive motor shaft is connected to the center of the distribution panel, driving the panel to rotate. The distribution panel has a ventilation hole. The first partition has a first through hole, which connects to one air duct of the distribution pipe. The second partition has a second through hole, which connects to the other air duct of the distribution pipe.

[0025] The actual usage method is as follows:

[0026] The various zones are separated by partitions, and the cabinet doors are equipped with grilles containing fans that act as fresh air fans. When running, these fans deliver fresh air to the corresponding zones via a rotating distribution plate. If all three zones require temperature control, the distribution plate can be kept rotating continuously. Alternatively, to create a more enclosed space within the cabinet, the distribution plate can be rotated so that its orifices do not align with any air duct. The exhaust system is the same as the fresh air system, except that the fresh air system is for intake, while the exhaust system is for exhaust. For example, when temperature control is required for the contact zone, the distribution plate orifice must be aligned with the corresponding air duct (i.e., the second orifice). In this case, both the fresh air and exhaust systems only perform high-speed temperature control on the contact zone, with minimal impact on the other two zones.

[0027] The temperature measurement device includes an RFID temperature measurement component, a fiber optic temperature measurement component, and an infrared spectral thermal imaging component. Each of the three temperature measurement strategies is equipped with a corresponding signal acquisition device. The acquired temperature signals are used to control the rotation of the drive motor below the distribution plate.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this invention is defined by the appended claims rather than the foregoing description, and it is therefore intended to include all variations falling within the meaning and scope of the equivalents of the claims within this invention.
