Background technology
UPS is that the English of uninterrupted power supply (uninterruptible power system) is called for short, and is the important external equipment that lasting, stable, continual power supply supply can be provided.On principle, UPS is a kind of collection digital and analog circuit, and control inverter and non-maintaining energy storage device are in the power electronic equipment of one automatically; On function, UPS can occur purifying civil power effectively when unusual at civil power; It mainly acts on is that certain time is powered to apparatus such as computer when civil power interrupts suddenly.Modern society is because the development of information technology, network has become part indispensable in people's live and work, the power supply reliability that constitutes the digital machine room of network has become key, and the reliable power supply of machine room is the most important thing, UPS is provided with in order to solve uninterrupted power supply, the three big basic functions of UPS: voltage stabilizing, filtering can not be interrupted.When mains-supplied, it is the effect of pressurizer and filter, and to eliminate or to weaken the interference of civil power, assurance equipment is worked normally; When civil power interrupts, it can be converted into perfect alternating current by the direct current that its direct current supply part energy storage devices such as () battery pack is provided again and use for load, wherein change powered battery and be generally the switching of 0 time by mains-supplied, so just make load equipment in imperceptible any variation, keep operation, really guaranteed running without interruption of equipment.UPS is the equipment that must be equipped with for one-level electric power system (being can not have a power failure in the equipment running process) especially.
In the prior art, the stand-by power supply of big-and-middle-sized UPS (being energy storage device) is used lead-acid battery entirely, and this is that discharge time is long because the capacity of lead-acid battery is big.But UPS in order to guarantee useful life, generally is in the floating charge state with lead-acid battery, and charging current can not be too big.According to the supporting power supply of the standard of UPS, even put after civil power disconnects under the situation of electricity, charging current can not be too big, is about C/200, and the lead-acid battery of having put electricity needed just can be full of fully in 200 hours approximately.After long-time (about as 10 hours) power failure occurring, the electric weight of lead-acid battery has almost been put, and has a power failure again about 10 hours after civil power is come in about 10 hours, and this moment, lead-acid battery was not full of fully, can only arrestment.This situation is unacceptable for the one-level electric power system.In order to prevent the generation of this situation, need rectify and improve whole ups power system.
Summary of the invention
The purpose of this utility model is to provide a kind of UPS corollary apparatus of sustainable power supply, and this device is realized sustainable power supply when frequent the power failure.
Technical solution:
The utility model is made up of the lead-acid battery stand-by power supply, and the lead-acid battery stand-by power supply comprises: lead-acid battery group, UPS1# uninterrupted power supply, alternating current Static Transfer Switch STS have been arranged in parallel Ni-MH battery group stand-by power supply on the lead-acid battery stand-by power supply.
The UPS2# uninterrupted power supply is connected with Ni-MH battery group and discharge controller respectively, the Ni-MH battery group is connected with the nickel hydride charging controller, the battery voltage detection analog input of cyclelog is connected with the Ni-MH battery group, the charging control output of cyclelog is connected with the nickel hydride charging controller, the discharge control output of cyclelog is connected with discharge controller, and discharge controller is connected with alternating current Static Transfer Switch STS.
Charging module cancellation in the utility model UPS2# uninterrupted power supply, on original lead-acid battery stand-by power supply, add one group of Ni-MH battery group stand-by power supply in addition, realize switching in zero second by STS (alternating current Static Transfer Switch) circuit between the uninterrupted power supply of two groups of stand-by power supplies, two groups of UPS uninterrupted power supplys one main are auxilliary, any one goes wrong, another can continue power supply, the fail safe that has improved power supply.Utilize the mechanism (0.2C charging) of Ni-MH battery quickly-chargeable to add a charging device simultaneously in the Ni-MH battery group, (about 5 hours) at first are full of the Ni-MH battery group at short notice when civil power is connected, the UPS uninterrupted power supply can continue power supply when guaranteeing to have a power failure once more, has solved frequent power failure of civil power and the problem of lead-acid battery group can not power continuously the time.
Two cover UPS uninterrupted power supplys one main are auxilliary, realize switching in 0 second by static STS transducer.If the 1#UPS stand-by power supply goes wrong, then can switch at once and continue power supply on the 2#UPS stand-by power supply, improved the fail safe and the duration of power supply, main is the characteristic of utilizing the Ni-MH battery quickly-chargeable, efficiently solves the civil power problem that UPS can not continued power when frequently having a power failure.
