What's the difference between UPS and batteries? I mean, yes
According to the basic application principle, UPS is a power supply protection device with energy storage devices, an inverter as the main component, a voltage stabilizing and frequency stabilizing output. It mainly consists of rectifier, accumulator, inverter and static switch.1) rectifier: rectifier is a rectifier device, simply speaking, is the exchange of (AC) into direct current (DC) device. It has two main functions: first, the alternating current (AC) is converted into direct current (DC), filtered to supply the load, or the inverter is supplied; and second, a charging voltage is supplied to the battery. As a result, it acts as a charger at the same time;2) storage battery: the battery is UPS, used as a device for storing electrical energy, it is connected by several batteries in series, and its capacity determines the time of its maintenance discharge (power supply). Its main functions are as follows: 1 when the city power is normal, the electric energy is converted into chemical energy and stored in the battery. 2, when the city power fails, the chemical energy is converted into electrical energy to provide the inverter or load;3) inverter: in popular terms, an inverter is a device that converts a direct current (DC) into an alternating current (AC). The utility model is composed of an inverter bridge, a control logic and a filtering circuit;4) static switch: static switch, also called static switch. It is a contactless switch. It is an AC switch made up of two silicon controlled rectifier (SCR) in reverse connection. Its closing and disconnection are controlled by logic controller. It is divided into two types: conversion type and combined type. The switched type switch is mainly used in two power supply systems. Its function is to realize automatic switching from one road to another, and the type switch is mainly used for parallel inverters and municipal power or multiple inverters.
The system shall have the power supply capability of providing 365 * 24 continuous high quality UPS inverters. This means that the UPS power supply system in the operation, does not allow any instantaneous power interruption / power outage, is not allowed by the municipal common electric AC bypass directly to the user by the power supply load. To this end, the UPS power supply system shall meet the following requirements:Due to the low failure rate of the UPS unit itself, the average failure free working time (MTBF) of the large UPS products is 200 thousand to 400 thousand hours.Using a highly fault-tolerant function of "N + 1" type UPS redundancy and machine system to improve the reliability of UPS power system further ("1 + L" type of redundancy and machine system the typical MTBF value can reach 1 million 400 thousand ~ 2 million hours).In the whole set of UPS power supply system, there should be no single point bottleneck hidden trouble.- - allowing the maintenance and repair of power failures under the condition of continuous power supply of UPS inverters.In case of a short circuit fault at the user's device, the impact of the fault should be reduced to the smallest possible extent.
UPSUPS Chinese means "ups", "Uninterruptible Power Supply" is the English abbreviation, it can protect the computer system to continue to work for a period of time after a power outage in order to enable users to save an emergency, make you not due to power failure affected work or loss of data. It is in the computer system and network application, mainly has two functions: one is to use the emergency, to prevent a sudden power failure and affect the normal work, causing damage to the computer; the two is to eliminate the surge, the city electric moment of high voltage, low voltage, instantaneous wire noise and frequency offset "power pollution", the improvement of power supply quality, provide high quality power supply for computer system.
The UPS is an uninterruptible power supply and the livestock battery is a single device for storing electrical energyFor example, UPS is used in the computer if the power supply electric 220V normal through the ups to the computer power supply, and the battery inside the machine is full, if a sudden power outage, then UPS will immediately be 12V power battery into 220V to continue to provide computer work. During this period, the power supply will not be interrupted for the computer. Missing unsaved work.. What about batteries?.. He can only store 12V power.. And it can only release the voltage of 12V. Just like regular batteries. It's just big capacity!!
The role of UPSThe main functions of UPS are as follows:(L) interruptions in power, can use the battery through the inverter to convert DC to AC 220V power supply for computer and network systems, computer and network system can guarantee the normal operation of.(2) the utility model has the voltage stabilizing effect on the city electricity and can stabilize the voltage when the voltage of the power grid fluctuates.(3) harmonic interference, can inhibit the voltage sags, voltage surge, waveform distortion, electromagnetic interference and power pollution, provide power supply voltage stability, pure waveform for computers and other equipment, ensure the normal work of computer and network systems and data without interference.(4) avoid lightning stroke. Auto save the CPU controlled by UPS. Let the computer automatically save the battery before its battery is used up. As above is the basic function of UPS, other large UPS has many functions
