Accident barrier, rectification failure etc., according to the digital information and analog quantity information of acquisition terminal acquisition, certainly such as voltage decline, rectification
The information such as inspection information, failure or position can reflect be problem place；When the exchange of rectifying part inputs unchanged, direct current
Output changes (such as frequency, angle, mutation), it is detectable judge commutating circuit there are the problem of.If input voltage is normal, in
Between have and be spaced apart tripping, leading to output voltage is zero or the decline of the DC voltage that causes rectification to export due to the decline of input voltage
Situations such as, the input voltage decline rectified for another example, output voltage is normal, this may be due to the original inside rectification aging or rectification
Because leading to rectification failure, specific failure cause can be analyzed further according to position and isolation is spaced apart.
Follow function by inversion reflux, adjusted in the reasonable scope according to argument difference with difference on the frequency it is internal exchange it is defeated
Out, approach bypass input slowly with inversion, to realize that inversion is synchronous with bypass input；When the direct current of Converting Unit inputs just
Often, and inversion without output, be in this case usually not detect input and output sampled signal, i.e. input and output sample line
It falls off.Ups can issue alarm or automatic switchover at this time.It at this time may be due to taking if there is the very high situation of output voltage
The case where certain group coil of sample transformer disconnects or the related device of whole road of feedback signal is opened a way.
Wiring of the highly reliable uninterruptible power system battery pack structure of four redundancy of dual input compared to battery pack before this
Increasingly complex, the battery pack structure of the power-supply system is that battery is split into multiple batteries to be connected in parallel, and both end voltage is kept
Constant, the number of batteries in battery pack increases at this time, in this case, when a certain cell damage in battery pack, internal resistance increase
When big, the variation of entire battery voltage is not interfered with.Simultaneously will also voltage, electric current to every piece of battery both ends supervise
It surveys, the data monitored is then sent into central processing server, carry out intellectual analysis convenient for central processing server.
The utility model has the advantages that
The invention proposes a kind of methods of new raising uninterruptible power supply power supply reliability, have invented a kind of dual input four
Redundant uninterruptible power-supply system realizes seamless switching to guarantee its power supply reliability.This patent connects by adjusting primary system
Cable architecture, the input bypassed using the output of another ups as this ups dynamic, so that improve dynamic bypass input can
By property.By the real-time monitoring of frequency and argument etc. to bypass input, the exchange adjusted inside device in the reasonable scope is defeated
Out, thus improve bypass input with exchange output synchronism.It does not need to connect line synchro between ups, to reduce this
Preceding failure or interruption due to two mutual line synchros of uninterruptible power supply and the asynchronous generation ring for leading to entire ups power supply
A possibility that flowing into and burning out ups device.

In device；
As shown in Figure 1, the redundant circuit include: exchange the first input source, ups1, battery 1, exchange the second input source,
Ups2, battery 2；The input AC power supply that the first input source is DC source 1, ups1 is exchanged, the second input source of exchange is DC source
2, the direct current input of the input AC power supply of ups2, ups1 is to be powered by battery 2 for it, and the direct current input of ups2 is by battery 1
It powers for it, i.e., same ups, by the power supply power supply from two different electrical power points, forms a kind of double ups intersections in importation
Power supply source；
As shown in Fig. 2, the secondary circuit includes: the first input source of exchange, exchanges the second input source, battery 1, battery 2,
Ups1, ups2, wherein ups1 and ups2 is connected by the structure of parallel running mode, i.e. what the output of ups1 was bypassed as ups2
Input, the input that the output of ups2 is bypassed as ups1, the bypass are divided into dynamic bypass and static by-pass, form one
Ups circuit related with four power supply points exchanges the first input source, exchange the second input source, battery 1, battery 2, secondary
Part is set in the central processing unit in host and each ups internal processor, thus constitutes two four redundant uninterruptibles of input
Power-supply system；
The acquisition control circuit: two terminals of the central processing server connection ups1 and ups2 in host, not
Intermittent two terminals to ups1 and ups2 carry out data acquisition, and data collected are analyzed and handled, and will locate
Data after reason are transmitted to host.
The power-supply system establishes an acquisition control circuit, is monitored to the power supply of secondary circuit.As shown in figure 4,

Collect the digital information and analog quantity information of terminal acquisition, such as voltage decline, rectification self-test information, failure or position information can be anti-
It mirrors to be the place of problem.
When the exchange input of rectifying part is unchanged, direct current output changes (such as frequency, angle, mutation), can detect
Judge commutating circuit there are the problem of.If input voltage is normal, centre, which has, is spaced apart tripping, and leading to output voltage is zero or due to defeated
Situations such as decline for the DC voltage that the decline for entering voltage causes rectification to export, the input voltage decline rectified for another example, output electricity
Positive pressure is normal, this may be inside the rectification aging or rectification due to lead to rectification failure, further according to being spaced apart position and isolation
State can analyze specific failure cause.
Adjusted in the reasonable scope according to argument difference with difference on the frequency it is internal exchange output, both make slowly to approach, carry out reality
Now synchronous with bypass input, this process is to follow function by inversion reflux to realize.When the direct current of Converting Unit is defeated
Enter normally, and inversion is without output, is in this case usually not detect input and output sampled signal, i.e. input and output take
Line-transect falls off.Ups can issue alarm or automatic switchover at this time.If there is the very high situation of output voltage, may be at this time by
In certain group coil of sampling transformer disconnects or the related device of whole road of feedback signal is opened a way the case where.
The power-supply system battery pack structure is increasingly complex compared to the wiring of battery pack before this, and such as normal battery pack is 10
The capacity of a a string of 24V battery composition of structure, each battery can be bigger, just forms a big battery pack in this way.And
The battery pack structure of the power-supply system is that the battery that the battery of 24V, 100 megawatt hours are split into 5 20 megawatt hours is connected in parallel on one
It rises, both end voltage 24V is remained unchanged, and the number of batteries in battery pack increases 50 from original 10 at this time, this
In the case of, when a certain cell damage in battery pack, internal resistance increase, do not interfere with the variation of entire battery voltage.Together
When will also voltage, electric current to every piece of battery both ends be monitored, the data that monitor then are sent into central processing server,
Intellectual analysis is carried out convenient for central processing server.
There are central processing servers for the power-supply system.By central processing server to uninterruptible power supply ups1, ups2 two
The data of a terminal are acquired, and carry out intellectual analysis to collected data, are found out specific fault point and are provided safety and arrange
It imposes and last processing method, ultimately forms decision information and send control host to.
