Description
Technical field
This utility model belongs to emergency service power technique fields, is specifically related to the N+M redundancy ups system of the multiple subsystem composition of a kind of Centralized Monitoring.
Background technology
The UPS being known as emergency service power supply is widely used in every profession and trade department, provides power supply guarantee for critical loads, and its job stability, safety are of crucial importance.And in use there is the miscarriage to UPS electric power system due to user, safeguard the not in place or problem such as accumulator is aging, capacity configuration is improper, the fault such as easily cause UPS electric power system line short, accumulator punctures, even result in the generation of fire, cause security incident and heavy losses.
State Patent Office disclose application number 201510149311.9 " the remote maintenance device of uninterrupted power source " its describe in the introduction " [0003] UPS duty need lean on plant stand person on duty's periodical inspection substation equipment obtain.However as power network development, transformer station's quantity increases, and causes manual patrol cycle stretch-out.Once UPS accumulator breaks down, only manually making an inspection tour and be difficult to find in time, this can affect the safe operation of RTU in transformer station.And in the use procedure of UPS, at least need every year accumulator carries out a charge and discharge maintenance job, manually carry out charge and discharge maintenance work labor intensive material resources." in order to solve the problems referred to above; propose " the remote maintenance device of uninterrupted power source "; this technical scheme only monitors accumulator battery string terminal voltage; health and the working condition of each accumulator can not be monitored; and the discharge and recharge of battery service also simply regulates electrical path; the charge-discharge control circuit of UPS itself cannot be utilized, it is impossible to realize rational charge and discharge process, the problem that therefore can not effectively solve required solution.
State Patent Office discloses application number: 201510115561.0 " supervising devices of uninterrupted power source accumulator charging voltage " its describe in the background technology and summary of the invention of description " [0003] but; current UPS charger would be likely to occur, when charging to accumulator, the situation that charging voltage is too high or too low; cause UPS accumulator battery hold Electricity Functional decline; service life shorten, accumulator plate damage problem.[0004] embodiments of the invention provide the supervising device of a kind of uninterrupted power source accumulator charging voltage, the situation that charging voltage is too high or too low is would be likely to occur solving current UPS charger when charging to accumulator, the battery causing UPS accumulator holds Electricity Functional decline, service life shortens, the problem that accumulator plate damages." its technical scheme only monitors accumulator battery string terminal voltage; health and the working condition of each accumulator can not be monitored; being accomplished by adopting its technical scheme that each accumulator is installed supervising device if each accumulator will monitor that, this is clearly infeasible；Even if additionally each accumulator is installed a supervising device by this scheme, owing to its magnitude of voltage comparing terminal voltage ignores temperature and uses the environment impact on accumulator so that it is monitoring effect is had a greatly reduced quality.
State Patent Office also disclosed application number: 200710100691.2 " nested redundant uninterruptible power supply apparatus and methods " its in the background technology and summary of the invention of description, describe that " [0004] multiple different technology has been used for improving the reliability of uninterruptible power system.These technology include standby redundancy, series redundancy and parallel redundancy method.Typical standby redundancy UPS structure include operating on standby basis, not bringing onto load or only band portion load, one or more UPS unit, it can replace fault UPS cell operation immediately by the switching of load.Typical series redundancy is arranged and is comprised the first and second UPS connected in a series arrangement, wherein, in the first operating mode, oneth UPS is bypassed and the 2nd UPS is for bringing onto load, in the second operating mode, 2nd UPS is bypassed and a UPS is for bringing onto load, and so, the first and second UPS can mutually as the standby backup (standbybackup) of the other side.[0005] in typical parallel redundancy is arranged, multiple uninterrupted power sources (UPS) are coupled in parallel to load, in order to provide the load capacity of redundancy and the commonly provided increase.The parallel redundancy of AC power supplies (such as UPS) is arranged at such as Tassitino, et al. Jr. U.S. Patent No. 5,745,357, Tassitino, et al. Jr. U.S. Patent No. 6, the U.S. Patent No. 6 of 549,440, Luo et al., 803, the U.S. Patent No. 6,118 of 679, Wallace et al., 680, the U.S. Patent No. 4,104,539 of Hase, the U.S. Patent Publication No.2005/0162792 of Wang et al., and the U.S. Patent Publication No.2005/0073783 of Luo et al. is described." its summary of the invention is the UPS enabling selectively according to payload and disabling in redundancy group, controls the quantity standby each other between multiple UPS unit；Also be only standby as standby UPS unit, run all do not account for accumulator with standby situation, also without the maintainability discharge and recharge that accumulator considers to carry out necessity.
It is known that, the safety of UPS, reliability are decided by the health status of ups system, and the health status of ups system depends on the health status of accumulator, (when UPS standby operation, circuit breaks down problem, can detect and report to the police maintenance immediately), the situation of accumulator is then seldom effectively detected, and its safety makes people worried.The wide variety of lead-acid accumulator of current UPS, the factor affecting its safety is a lot, and situation is also more complicated, concludes the key factor having at least following several aspect:
1) accumulator that UPS adopts is mostly accumulation energy type accumulator, and its charge-discharge electric power is subject to product design and adopts the restriction of material and technique, and properties of product are 0.1C with charging and discharging currents when suggestion use is temperature 25 DEG C when dispatching from the factory；Continuous operation < 5 minutes during general also suggestion 0.3C；Accumulator≤2 hour of major part user's ups system configuration, reach 0.5C, also >=0.25C during 50% load operation during oepration at full load at present；This has a strong impact on the health of accumulator and there is potential safety hazard；Particularly accumulator internal resistance is inconsistent or when part is aging, can breaking out of fire when very easily having an accident serious；
2) generally the accumulator of UPS is chronically at floating charge resting state, and pole plate crystallization causes that capacity declines, it is necessary to accumulator carries out high current charge-discharge within the regular hour to reach to melt crystal active chemical substance therein.
3) in many accumulator, certain difference is existed for during owing to dispatching from the factory, in ageing process gradually, difference is also gradually increased, and the monitoring Main Basis of accumulator is exactly terminal voltage by current ups system, it is likely to have resulted in indivedual accumulator super-charge or charge less when the terminal voltage of accumulator battery string is normal, very easily causes indivedual accumulator premature failure to cause the generation of accident.
4) accumulator needs periodicmaintenance, detect one by one at least for twice maintainability discharge and recharge and accumulator every year, manually carry out at present substantially, waste time and energy, be prone to careless omission and this process needs the regular hour to affect design and the service ability of ups system.
5) in order to improve the reliability of uninterruptible power system UPS, prior art generally adopts N+M redundancy ups system, namely more than one redundancy UPS unit is increased so that it is mutually as the standby backup cellular system of the other side, during another UPS fault, the UPS unit of standby backup is replaced；But all lack and accumulator is carried out on-line maintenance, it is impossible to overcome the relevant issues in above-mentioned accumulator use procedure.
