Description
Technical Field
[0001] The utility model relates to the technical field of power supply, in particular to a UPS power supply. Background Art
[0002] With the continuous innovation and development of technology, public power distribution systems have become quite reliable. However, studies have shown that even the most perfect mains power network cannot fully meet the needs of uninterrupted critical data processing and operation centers. Faced with the possibility of downtime and data processing errors caused by mains power and human operation, most companies choose to install an uninterruptible power supply (UPS) system between the public power distribution system and its critical loads. The UPS system design and configuration scheme selected for the application environment directly affects the availability of IT equipment in that application environment. There are many factors that affect system availability, including human error, equipment reliability, maintenance level, and recovery time. The impact of each of these factors on the availability of the entire system is largely determined by the selected configuration scheme.
[0003] UPS power supplies in the existing technology usually include backup, online interactive and online UPS. The appropriate type is selected according to the load requirements and budget. UPS power supply configuration solutions include centralized or decentralized configurations. Centralized configuration is suitable for equipment that is centralized and uniformly uses the same type of UPS system, while decentralized configuration is suitable for equipment that is dispersed or requires different types of UPS. When a traditional UPS power supply fails, the UPS power supply manufacturer must send after-sales personnel to conduct on-site inspection and repair. During the inspection and repair period, it needs to switch to bypass mode. If the mains power is cut off, it will not work. This shows that the existing UPS power supply has poor flexibility and is relatively complicated to maintain. Users cannot flexibly select, replace or add modules according to their own needs to achieve flexible configuration of the UPS power supply. Utility Model Content

[0013] In order to more clearly illustrate the technical solution of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.
[0014] Figure 1 This is a schematic diagram of the UPS power supply provided by the utility model. DETAILED DESCRIPTION
[0015] It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs.
[0016] See also Figure 1 The utility model provides a UPS power supply, including: a power module, a UPS module, a battery module, an output power distribution module, and a bypass power supply module.
[0017] Among them, the input end of the power module is connected to the main power supply, the output end of the power module is connected to the input end of the UPS module, the output end of the UPS module is connected to the battery module and the output distribution module respectively, and the output distribution module is connected to the bypass power supply module; the power module, UPS module, battery module, output distribution module, and bypass power supply module are all hot-swappable connections. The modular design improves the flexibility and scalability of the system. Users can flexibly select, replace or add modules according to their own needs to achieve flexible configuration of the UPS power supply.
[0018] In this embodiment, the input of the power module is equipped with a main switch and a first switch CB1. The power module provides initial power to the entire UPS, ensuring stable and appropriate power, and performing necessary voltage and current conversion. The UPS module controls power flow, providing stable, uninterrupted power to the load and managing battery charging and discharging. The battery module stores energy and provides temporary power during utility power outages.
[0019] The bypass power supply module is provided with a bypass switch and a second switch CB2. When the UPS power supply fails, the bypass power supply module allows the power supply to bypass the UPS and directly supply power to the load, thereby improving the reliability of the system and ensuring that the load will not be powered off when the UPS fails.
[0020] The output power distribution module distributes power to connected devices, ensuring they receive the power they need. It includes relay K1, the normally closed point of relay K2, the normally open point of button SB1, relay K2, the normally closed point of relay K1, the normally open point of button SB2, the normally open point of relay K1, the normally open point of relay K2, a third switch CB9, and a power distribution switch. The output of the UPS module is connected to the third switch CB9 via the normally open point of relay K1, which is then connected to the bypass power supply module via the normally open point of relay K2. The output of the UPS module is connected to two branches: one branch includes relay K1, the normally closed point of relay K2, and the normally open point of button SB1, connected in sequence; the other branch includes relay K2, the normally closed point of relay K1, and the normally open point of button SB2, connected in sequence. The third switch CB9 is connected to the power distribution switch. The power distribution switches include power distribution switch Q1, power distribution switch Q2, power distribution switch Q3, power distribution switch Q4, and power distribution switch Q5; the third switch CB9 is connected to the power distribution switches Q1, power distribution switch Q2, power distribution switch Q3, power distribution switch Q4, and power distribution switch Q5 respectively.
[0021] The UPS power supply provided by this utility model operates as follows: When the mains power is normal, power is supplied by the mains input, converted by the power module, and then supplied to the UPS module and the load equipment, while also charging the battery module. The UPS module monitors power quality to ensure stable and uninterrupted power output to the load. If the mains power is interrupted, the UPS module immediately switches to the battery module to continue powering the load until the mains power is restored or the battery is depleted. The bypass power module is activated when the UPS system requires maintenance or a malfunction occurs, ensuring continuous operation of the load.
[0022] The UPS power supply of the present invention adopts a modular design and has strong redundancy. Considering safety issues, many users will add 1-2 modules to the original ones to prevent accidents. The power module, UPS module, battery module, output distribution module, and bypass power supply module are all connected by hot-swappable connection, which can be upgraded and expanded online. Without stopping the machine, you can add modules online for upgrade and expansion. If one of the modules has a problem, a single person can complete the work, unplug it online, replace it by yourself, and then repair the faulty module or purchase it separately. This not only does not affect the normal work of the user, but also brings convenience to the enterprise. The biggest advantage of modularization is that it can improve the reliability and availability of the system, which not only meets the on-demand expansion of equipment in the later stage, but also reduces the initial purchase cost. The modular UPS power supply effectively solves the problem of on-demand expansion of investment planning and allows users to achieve dynamic growth as the business develops, thereby helping users to build and invest in stages when the future development direction is not yet clear.
