Description

Technical Field

[0001] This utility model relates to the field of power supply equipment technology, and in particular to a microcomputer-based AC / DC integrated power supply device. Background Technology

[0002] The microprocessor-based AC / DC integrated power supply unit integrates AC power distribution, DC charging, battery management, and monitoring functions into one unit. Through modular design and digital control technology, it achieves intelligent conversion and distribution of multiple power sources. Its core uses a microprocessor to monitor parameters such as voltage and current in real time, supporting automatic switching, fault isolation, and remote communication. Widely used in substations, industrial control, and other fields, it significantly improves power supply reliability and reduces system operation and maintenance complexity, making it a key device for achieving efficient power supply coordination in smart grids.

[0003] To ensure long-term stable operation of the equipment, daily maintenance should focus on module status, environmental adaptability, and data logging. Regularly check the filter capacitors and cooling fans of the AC input modules, cleaning dust to prevent overheating; monitor the current sharing performance of the DC output modules to avoid overloading any single module; the battery pack should undergo charge-discharge testing quarterly, calibrating its capacity and checking for oxidation of the connection terminals. Furthermore, historical data should be recorded using the equipment's built-in monitoring software to analyze load fluctuation trends and provide early warnings of potential faults. A comprehensive overhaul is recommended every six months, including tightening wiring terminals, verifying insulation performance, and updating control programs. Maintaining good ventilation and dryness in the equipment room is also crucial to prevent moisture or corrosive gases from damaging the equipment, thereby extending its service life and ensuring system safety.

[0004] Patent document CN210898165U discloses a microcomputer-based AC / DC integrated power supply device, including a power supply body. The bottom of the power supply body has a placement groove, and the interior of the power supply body has four hollow cavities. This microcomputer-based AC / DC integrated power supply device utilizes a worm gear to rotate a threaded rod. This causes a movable sleeve to move downwards under the action of the threaded rod, which in turn moves the casters downwards. This interaction force causes the power supply body to move upwards, thus pushing the power supply body. A stabilizing spring ensures stability during the movement of the movable sleeve. The worm gear and threaded rod prevent the casters from moving due to gravity when the worm gear is not rotating. This device, through a series of mechanical structures, allows the power supply body to move relatively upwards when needed, facilitating pushing after movement.

[0005] As in the prior art of the aforementioned patent, the power supply device is sealed by a closed door. However, the power supply device often requires internal inspection and maintenance. During the inspection process, the modules inside the device need to be disassembled for inspection or disassembled from the side shell of the module. It is not necessary to remove the module from the inside of the device. However, in the prior art, including the aforementioned device, the closed door of the device can only be opened from the front, which is inconvenient for the internal inspection process.
