Description
Technical field
The portable binary-coded decimal detection device based on sub-connecting switch of transformer that the utility model relates to a kind of.
Background technique
The tap switch of power transformer is for adjusting transformer output voltage.Due in electric system power grid everywhere
Voltage be not it is identical, in order to enable transformer no matter be mounted on power grid where can output rated voltage, just
It is provided with multiple tap in the high-voltage winding of transformer, and tap is connected on tap switch, passes through tap switch and power grid phase
Even.
In substation perhaps converter station the adjusting of tap switch be by control system according to Power auto-adjustment or
The staff of substation or converter station is adjusted on operation work station manually.Fig. 2 is that substation's tap changer system connects
Schematic diagram is connect, left side is control system (backstage), and (loaded switch gear signal BCD-1 to BCD-20) is to the right by 6 cables
The change of current of side becomes cooler bin and sends binary-coded decimal signal, adjusts tap after the binary-coded decimal decoder conversion built in the change of current becomes cooler bin and opens
The gear of pass.
Currently, often there is tap switch backstage display gear in the O&M of substation or converter station, the change of current turns cold but
The PLC of case shows that gear, tap switch ontology show the inconsistent situation of gear three, and operation maintenance personnel needs to hold general-purpose at this time
Table carries out potential measurement to the binary-coded decimal signal that control system exports, such as the measurement change of current becomes 6 binary-coded decimal receiving ends on cooler bin
The current potential of son (X4:57-62 this), then will electrogram one by one, carry out binary-coded decimal conversion, gear value will be obtained, to sentence
Determine failure cause.
In this way by personnel record, manual conversion relies on the technical ability water of operation maintenance personnel so that the result of measurement is not objective enough
It is flat, and result is not intuitive, inconvenient.
Utility model content
To solve the above problems, the utility model provides a kind of portable binary-coded decimal detection based on sub-connecting switch of transformer
Device can directly display gear, avoid subjective error caused by manual record, conversion.
In order to achieve the above object, the technical scheme adopted by the utility model is that:
A kind of portable binary-coded decimal detection device based on sub-connecting switch of transformer, including power supply, processor, digital-scroll technique
Device and multiple voltage transformers, power supply are connect with processor, and the input terminal of processor is connect with the output end of each voltage transformer,
The output end of processor is connect with digital display, and voltage transformer is additionally provided with for becoming cooler bin binary-coded decimal receiving end with the change of current
The cable of son connection.
Further, the power supply is lithium battery.
Further, the processor is single-chip microcontroller.
Further, the connector of the cable is contact pin type connector.
Compared with the prior art, the advantages of the utility model are:
Realize the automatic conversion and intuitive display of gear binary-coded decimal, it is convenient and efficient；Personnel record and conversion are not needed, is avoided
Error caused by subjective factor；Internal battery module, it is easy to carry using simple；Direct contact type does not influence system work,
System blackout can not be needed with on-line checking.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is substation's tap changer system connection schematic diagram.
Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment:
As shown in Figure 1, a kind of portable binary-coded decimal detection device based on sub-connecting switch of transformer, including power supply 1, processing
Device 2, digital display 3 and 6 voltage transformer 4, and be grounded by GND terminal.
Power supply 1 is connect with processor 2, and the input terminal of processor 2 is connect with the output end of each voltage transformer 4, processor 2
Output end connect with digital display 3, voltage transformer 4 is connected with cable 5, be used for and the change of current become cooler bin binary-coded decimal receive
Terminal X4:57-62 is connected, and the connector of cable 5 can be made contact pin type, and a clip can also be added on contact pin.
Power supply 1 uses rechargeable lithium battery, powers for entire detection device, which is provided with a master switch, to control inspection
Survey work/closed state of device.Voltage transformer 4 for read the change of current become 6 binary-coded decimal receiving terminal on cooler bin (X4:
57-62 this) current potential, if it is+110V, then voltage transformer 4 exports " 1 " to processor 2, if voltage is -110V, voltage
Mutual inductor 4 exports " 0 " to processor 2.Processor 2 uses single-chip microcontroller, receives voltage transformer 4 and is transmitted through the electrical potential information come, and
Data are subjected to conversion output to digital display 3, show gear.Specific conversion mode is consistent with manual conversion, passes through place
The automatic conversion of reason device 2, which can be avoided manual conversion, to be in the presence of calculating mistake, and largely saves Extrapolation time.
In use, 6 cables 5 are sequentially ingressed into the end X57, X58, X59, X60, X61 and X62 that the change of current becomes cooler bin
Son, the other end are grounded by GND terminal；The switch of power supply 1 is opened, digital display 3 shows gear at once；Operation maintenance personnel observation
Gear can confirm abort situation compared with the gear of backstage；Detection finishes, and closes power supply 1 and switchs, takes out stitches.
The check device of the utility model is disposably measured the current potential of all terminals by 6 voltage transformers 4, passed through
2 fast conversion of processor goes out gear value, and by 3 real-time display gear of digital display, when substantially reducing binary-coded decimal detection
Between, improve accident analysis efficiency.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
