Description
Technical field
The utility model belongs to transformer testing instrument field, and more particularly to one kind can remember relay working condition
The transformer synthesis test system of record.
Background technology
, it is necessary to realize the switching between different coils by relay, thus there are one when transformer synthesis is tested
The relay assembly of a matrix distribution, the service life of relay is limited, and in a large amount of tests, relay often goes wrong,
It is difficult investigation problem place when system work goes wrong, still needs the control of measuring relay one by one at this stage
Then signal judges whether the conducting state of relay is normal.Such a one is manually investigated time-consuming and energy, and
Each relay work is associated in system, and a unit, which goes wrong, can also damage the unit of other normal works.
The content of the invention
In view of the deficiencies of the prior art, devise a kind of can remember the work times of relay the utility model
Record, and the transformer synthesis test system that can be shown on the human-computer interaction interface of integrated testing instrument for transformer, user
The relay for being closed number and approaching or transfiniting can be replaced according to the data that system provides, it is entire to prevent that relay damaged from influencing
The work of system also can quickly position the relay for the problem of being likely to occur, shorten lookup when system occurs abnormal
It the time of problem, is convenient for changing, prevents situation from further deteriorating.
Technical scheme is as follows：
A kind of transformer synthesis tests system, including integrated testing instrument for transformer, it is characterised in that：The transformer
Comprehensive tester is connected with driving plate, and driving plate is connected with relay board, and the relay includes being connected with transformer coil
Relay matrix, further include the storage unit being arranged on relay board, the storage unit passes through driving plate and transformation
Device comprehensive tester connects.
The driving plate includes driving chip and the scan interface being connected with integrated testing instrument for transformer.
The driving chip is 74HCT595 chips, and the scan interface is the data transmission interface of 25 cores.
In conclusion have the advantages that：
The utility model devise it is a kind of the work times of relay can be recorded, and can be in transformer synthesis
The transformer synthesis test system shown on the human-computer interaction interface of tester, the data that user can provide according to system
The number relay that approaches or transfinite is closed to replace, prevents relay damaged from influencing the work of whole system, also can be
When system occurs abnormal, the relay for the problem of being likely to occur can be quickly positioned, the time to search problem is shortened, is convenient for changing,
Prevent situation from further deteriorating.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
1 is integrated testing instrument for transformer in figure, and 2 be relay board, and 3 be driving plate, and 21 be storage unit, and 22 be relay
Device matrix, 31 be driving chip, and 32 be scan interface.
Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of transformer synthesis test system, including integrated testing instrument for transformer 1, transformer synthesis is surveyed
Try factory testing and certification test that instrument is suitable for each essential electrical performance of power transformer, safe to use, the dominant term of experiment
Mesh using color monitor, operates full Chinese prompt, realizes the real time monitoring to testing overall process；The transformer is comprehensive
It closes tester 1 and is connected with driving plate 3, driving plate 3 is connected with relay board 2, and the relay board 2 includes and transformer coil
The relay matrix 22 of connection, further includes the storage unit 21 being arranged on relay board, and the storage unit 21 passes through drive
Movable plate 3 is connected with integrated testing instrument for transformer 1, and integrated testing instrument for transformer is single to storage by the data transmission channel of driving plate
Member carry out data write-in and reading, the storage unit be ferroelectric memory, ferroelectric memory (FRAM), ferroelectric memory
Access rate it is very fast, power-down conditions storage information it is not easy to lose, ferroelectric memory is necessarily mounted on relay board, such energy
Enough ensure that the data inside storage unit can be corresponding with relay matrix, overcome memory mounted on driving plate or transformation
The problem of being likely to occur confusion on device comprehensive tester is formatted storage unit operation without in each test.
The driving plate 3 includes driving chip 31 and the scan interface 32 being connected with integrated testing instrument for transformer 1.
The driving chip 31 is 74HCT595 chips, and the scan interface 32 is the data transmission interface of 25 cores.
The driving chip can decode the control signal that integrated testing instrument for transformer is sent, and can drive corresponding
Relay is acted, and the data that scan interface is realized between integrated testing instrument for transformer and driving chip and storage unit are led to
Letter.
In conclusion have the advantages that：
The utility model devise it is a kind of the work times of relay can be recorded, and can be in transformer synthesis
The transformer synthesis test system shown on the human-computer interaction interface of tester, the data that user can provide according to system
The number relay that approaches or transfinite is closed to replace, prevents relay damaged from influencing the work of whole system, also can be
When system occurs abnormal, the relay for the problem of being likely to occur can be quickly positioned, the time to search problem is shortened, is convenient for changing,
Prevent situation from further deteriorating.
