Abstract

The invention provides a high-reliability UPS (Uninterrupted Power Supply) system. The high-reliability UPS system is characterized in that the reliability of a power supply system is improved through a redundant structure; two UPS are of the same capacity and averagely bear the load; when any one of the UPS suffers from a fault, another UPS can independently bear the operation under the whole load; the UPS system also brings the EPO emergency shutdown function; an EPO is positioned at a rear panel of an UPS unit; a terminal can switch off an UPS power supply through the EPO in order to cut off the UPS in emergency; the UPS system is also equipped with a repair switch, and the UPS suffering from the fault can be isolated and repaired; end of the repair switch is connected with a mains supply, and while the other end of the repair switch is connected with an output power supply. The high-reliability UPS system has the characteristics that the high-reliability and high-quality output power supply is brought, the fault isolating function is improved, and the overload resistance and the short circuit resistance are outstanding.

Description

A kind of ups system of high reliability
Technical field
The present invention relates to a kind of ups system of high reliability.
Background technology
Along with the develop rapidly of Internet network, ecommerce, IDC machine room, the availability of user to UPS electric power system is had higher requirement, arrived and required that availability is the degree of 99.999%, also namely in 1 year 365 days, the power-off time of UPS electric power system can not more than 5 minutes.But if from the angle of UPS unit, no matter how its technology develops, and does not still break away from the restriction of capacity and reliability.So, we, in order to meet the capacity of user to UPS and the requirements at the higher level of reliability better, realize the raising of ups system reliability.On the basis of unit, the raising of UPS capacity and reliability can be realized by the method combining namely redundancy link.Guarantee computer, communications network system or the industrial control systems such as computer/server, memory device, the network equipment, need the industrial equipment etc. of continuous running to provide continual supply of electric power.
Summary of the invention
The object of the present invention is to provide a kind of ups system of high reliability, improve the reliability of electric power system by redundancy structure.Identical and the mean allocation load of two UPS capacity, when wherein any fault, an other UPS independently can bear the operation of whole load.
For achieving the above object, the present invention is achieved through the following technical solutions:
A ups system for high reliability, is characterized in that, is improve the reliability of electric power system by redundancy structure, the identical and mean allocation load of two UPS capacity, and when wherein any fault, an other UPS independently can bear the operation of whole load.
Described ups system is also provided with EPO emergency cutoff function, and EPO is positioned at UPS unit rear board, and described terminal in case of emergency can turn off ups power by EPO, closes UPS.
Described ups system is also provided with service switch, and fault UPS can carry out isolation maintenance; One end of described service switch connects mains supply, and the other end of described service switch connects out-put supply.
Described ups system is also provided with Air Filter, and Air Filter can avoid a large amount of dust to enter UPS, more fully protects machine; UPS is used in high dust, high smog area; the installation of Air Filter is very important, and can play good dust-proof effect, improves UPS reliability further.
Compared with prior art, the invention has the beneficial effects as follows: the UPS unit in described UPS redundant system is the organic whole after combination, independent separately again separately; In the system, any portion fault all can not affect the normal operation of whole system, nor can leave any hidden danger.There is the features such as high reliability, high-quality out-put supply, good Fault Isolation function, excellent anti-overload anti-short circuit capability.The UPS of different brands and capacity can form hot backup system.Install simple, do not need adjustment, the later stage is installed additional also easy.Easy to maintenance, separately can carry out, influence each other little.

Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
A ups system for high reliability, improves the reliability of electric power system by redundancy structure, the identical and mean allocation load of two UPS capacity, and when wherein any fault, an other UPS independently can bear the operation of whole load.Described system is that the output by two being had equal-wattage UPS is placed in the state of same amplitude, same-phase and same frequency and is directly together in parallel.During normal work, respectively bear 1/2 load current by two UPS, just in case when wherein a UPS is out of order, by the UPS be left to bear whole load.The mean failure rate operating time of this combining system is 7 ~ 8 times of individual UPS, thus greatly improves the reliability of system.
Described ups system is also provided with EPO (Emergent Power Off) i.e. emergency cutoff function, and EPO is positioned at UPS unit rear board, and described terminal in case of emergency can turn off ups power by EPO, closes UPS.
Described ups system is also provided with service switch, and fault UPS can carry out isolation maintenance; One end of described service switch connects mains supply, and the other end of described service switch connects out-put supply.
Described ups system is also provided with increase Air Filter, and Air Filter can avoid a large amount of dust to enter UPS, more fully protects machine; UPS is used in high dust, high smog area; the installation of Air Filter is very important, and can play good dust-proof effect, improves UPS reliability further.
The principle of described system is explained below with Fig. 1.
When using UPS1 as main out-put supply using UPS2 as guest machine time, the output of guest machine UPS2 need be connected with the bypass Bypass1 input of UPS1, now the bypass Bypass1 input of UPS1 must disconnect with the input of UPS1.Under normal circumstances, powered to the load by UPS1, and UPS2 is in warm standby state no-load running; When UPS1 fault, UPS2 puts into operation and takes over UPS1 and continue to power to the load.Only have when UPS2 is due to overload or fault of converter, just closes bypass switch Bypass2, load changes by mains-supplied.
As shown in Figure 3, the present embodiment is also provided with service switch Q3, and one end of described service switch connects mains supply, and the other end of described service switch connects out-put supply.When need repairing UPS time, closed service switch Q3, disconnects main path switch Q1, by-pass switch Q2 and output switch Q4, just when not affecting electrical appliance normal electricity consumption, can keep in repair UPS equipment.
As shown in Figure 2, the present embodiment is also provided with emergency cutoff switch, and 1-2 short-term connects, and makes it be in connection status always.When 3-4 opens, UPS performs emergency cutoff.
