Description

Technical Field

[0001] The present invention relates to the technical field of UPS power supplies, and particularly to a parallel operation system and circuit of a UPS power supply. Background Art

[0002] In the application of modern large data center UPSs, the expansion of the system and the upgrade of reliability redundancy are becoming more and more frequent. However, in the design and subsequent transformation of the parallel operation system, due to the limitation of the installation location, the distance between UPSs is too far to be paralleled.

[0003] With the increase of the load, the UPS system has no redundancy, and the reliability of the system cannot meet the needs of the load. It is necessary to transform the system, but there is not enough space to place the UPS system. Summary of the Invention

[0004] The purpose of the present invention is to provide a parallel operation system and circuit of a UPS power supply to solve the problem that there is not enough space to place the UPS system.

[0005] To achieve the above purpose, the present invention provides a parallel operation system of a UPS power supply, including a disassembly and assembly component and an installation box body for accommodating the UPS power supply. The disassembly and assembly component includes a movable box body, a spring and a U-shaped frame. The installation box body has an installation cavity. The movable box body is detachably connected to the installation box body. The movable box body is located above the installation box body. The movable box body has a card slot. Two ends of the spring are respectively fixedly connected to the U-shaped frame and the installation box body. The spring is located inside the installation cavity. The U-shaped frame is slidably connected to the installation box body. One end of the U-shaped frame is located inside the installation cavity, and the other end of the U-shaped frame is located inside the card slot.

[0006] The installation box body can accommodate the UPS power supply. The disassembly and assembly component can increase the accommodation space of the entire parallel operation system of the UPS power supply. When the accommodation space is insufficient during the parallel operation of the present parallel operation system of the UPS power supply, the movable box body can be placed above the installation box body. The spring abuts against the U-shaped frame, so that one end of the U-shaped frame enters the inside of the card slot, thereby fixing the movable box body above the installation box body, making the movable box body communicate with the installation box body, and thus forming a larger accommodation space to solve the problem that there is not enough space to place the UPS system. When it is necessary to disassemble the movable box body, press the U-shaped frame to make the U-shaped frame withdraw from the card slot, and then the movable box body can be taken off from the installation box body, and the operation is very convenient.

[0007] Wherein, the disassembly and assembly component further includes two movable rings, and the two movable rings are respectively movably arranged on both sides of the movable box body.

[0008] The movable ring is used to facilitate the staff to lift the movable box body, so as to remove the movable box body from the installation box body.

[0009] Wherein, a receiving cavity is arranged on the outer side of the movable box body, and the movable ring is movably arranged inside the receiving cavity.

[0010] The movable ring can rotate inside the receiving cavity. When the movable ring is not needed, the movable ring rotates under its own gravity to fit with the movable box body so that the movable ring is completely located inside the receiving cavity to reduce the occupied volume. When the movable ring is needed, the movable ring can be rotated out of the receiving cavity for the staff to use.

[0011] Wherein, a plurality of positioning frames are arranged at intervals on the bottom side of the movable box body, and a plurality of positioning grooves corresponding to the positioning frames are arranged on the top of the installation box body. After the movable box body and the installation box body are connected, the positioning frames are located inside the positioning grooves.

[0012] When installing the movable box body, align the positioning frames with the positioning grooves and insert them to position the movable box body, so as to facilitate the installation of the movable box body on the installation box body.

[0013] Wherein, the UPS power supply parallel system further includes a sealing component, and the sealing component is arranged at the connection between the movable box body and the installation box body.

[0014] The sealing component is used to seal the contact part between the movable box body and the installation box body.

[0015] Wherein, the sealing component includes a first L-shaped frame and a second L-shaped frame. Limiting columns are arranged at both ends of the first L-shaped frame, and limiting openings are provided at both ends of the second L-shaped frame. The limiting columns at both ends of the first L-shaped frame are respectively located in the limiting openings at both ends of the second L-shaped frame.

[0016] When installing the first L-shaped frame and the second L-shaped frame, align the limiting columns with the limiting openings and insert them to position the first L-shaped frame and the second L-shaped frame, and fix them at the connection between the movable box body and the installation box body, so as to seal the connection between the movable box body and the installation box body.

An accommodation cavity 108 is arranged on the outer side of the movable box body 102. The movable ring 107 is movably arranged inside the accommodation cavity 108. The movable ring 107 is used to facilitate the staff to lift the movable box body 102, so as to facilitate removing the movable box body 102 from the installation box body 101. The movable ring 107 can rotate inside the accommodation cavity 108. When the movable ring 107 is not needed, the movable ring 107 rotates to fit with the movable box body 102 under the action of its own gravity so that the movable ring 107 is completely located inside the accommodation cavity 108 to reduce the occupied volume. When the movable ring 107 is needed, the movable ring 107 can be rotated out of the accommodation cavity 108 for the staff to use.

[0032] Secondly, a plurality of positioning frames 109 are arranged at intervals on the bottom side of the movable box body 102, and a plurality of positioning grooves 110 are arranged on the top of the installation box body 101 corresponding to the positioning frames 109. After connecting the movable box body 102 and the installation box body 101, the positioning frames 109 are located inside the positioning grooves 110. When installing the movable box body 102, the positioning frames 109 are aligned with the positioning grooves 110 and inserted to position the movable box body 102, so as to facilitate the installation of the movable box body 102 on the installation box body 101.

When the power input is normal, the UPS stabilizes the power and supplies it to the load for use. At this time, the UPS is an AC voltage stabilizer, and at the same time charges the battery inside the machine; when the power is interrupted, the UPS immediately converts the DC electrical energy of the battery into AC power through the inverter switching method and continues to supply it to the load, so that the load can maintain normal operation without being damaged. UPS equipment usually provides protection against both too high and too low voltages. When over-limit or power outage occurs, the uninterruptible power supply UPS system turns on the UPS battery discharge working mode, that is, when the AC input voltage exceeds the range allowed by the UPS or the mains power is interrupted, the inverter and the battery are continuously put into operation to continue supplying power to the load. The UPS will continue to operate until the battery discharge time ends, or return to the normal operation mode when the mains power returns to normal.
