Uninterruptible power supply integrated power distribution device capable of expanding battery pack

Abstract

A UPS system comprises a rack and a plurality of assemblies accommodated in the rack; a power supply module, a battery module, a circuit breaker, a bypass switch, a display module, a main control module, a redundancy control module and an output transformer are arranged in the rack; the power supply module, the battery module, the main control module and the redundancy control module can be removed and inserted through the front part of the rack; during normal operation, a first power supply path is used, the power supply module provides power supply power for a load, the power supply module receives alternating current from the mains supply input and the alternating current flows to an AC / DC converter, the converted direct current is used for charging the battery module and supplying power to a transformer, and the transformer generates stable voltage to the load for the key load of the output; if a UPS component failure causes the UPS system to fail to operate, or if the UPS needs to be removed from the power path, a bypass switch is closed to create a direct path from the input mains power to the selectable output AC / DC converter and output through the transformer to the load.

Description

technical field [0001] This invention relates generally to electrical power supply sources and systems, and more particularly to uninterruptible power systems (UPS) and power distribution systems using enclosures or cabinets such as battery packs, power modules, or battery chargers. Background technique [0002] Uninterruptible power systems, commonly referred to as "uninterruptible power supply systems" or "UPS systems," are used for a variety of purposes. Such as providing stable, continuous, uninterrupted power for sensitive or critical applications (such as extensive computer networks). Another common use of UPS systems is to provide power protection for telecommunications equipment. Because application types, sizes and configurations, power requirements, signal requirements, etc. vary widely, those skilled in the art will readily appreciate that one size does not fit all and that one size and form of UPS systems Not all application requirements can be met. Indeed, ea...

Problems solved by technology

The traditional battery pack power supply and detection system has many disadvantages, such as poor reliability, high power consumption, poor flexibility, etc.; and the backwardness of the battery management system also leads to defects in thermal management and safety management; in addition, due to the use of wired transmission, When the number of battery nodes increases, there are problems such as cumbersome wiring and difficult maintenance, which may even cause fire accidents
