Description
Technical field
The present invention relates to a kind of power instrument, i.e. single-phase electric energy meter detection recorder.
Background technology
In the prior art, single-phase electric energy meter on-site detecting instrument generally used now can carry out electrical energy meter accuracy detection,
Experiment of having good luck can not be carried out, so all events detection can not be carried out, and work on the spot needs one kind to carry out electric energy meter whole
Item detection instrument.
The content of the invention
The purpose of the present invention is to provide a kind of Multifunctional single-phase electric energy meter detection recorder for above-mentioned deficiency.
The present invention technical solution be：Single-phase electric energy meter detects recorder, it is characterized in that being installed additional on electric energy meter
Printer interface, load current and leakage current measurement hook type current transformer are installed additional.
It is an advantage of the invention that：1st, compact, safety and stability, easy to use, the difficulty that comprehensively solve customer electricity runs into are designed
Topic, is surely widely used by the whole society.2nd, earth leakage detection functions can be realized, contrast test is protected to having good luck.
Embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is principle of the invention block diagram.
Fig. 2 is contour structures sketch of the present invention.
Fig. 3 is present invention measurement voltage, electric current, pulse wiring diagram.
Embodiment
Referring to Fig. 1, single-phase electric energy meter detection recorder, it is to have installed printer interface additional on electric energy meter, has installed load additional
Electric current and leakage current measurement hook type current transformer.
Load current measurement transformer acts on：Measuring customer power load electric current.
Leakage current measurement transformer acts on：Measuring customer or zero line grounding electric current also once be leakage current.
Referring to Fig. 2, contour structures sketch of the present invention.Parts title is as follows：1st, instrument body 2, LCD panel 3,
Power supply terminal（And voltage measurement terminal）4th, load current measurement transformer（50/1 0.2 grades）Access socket 5, leakage
Electric current measuring transformer（10/1 0.2 grades）Access socket 6, pulse indicator lamp 7, reset switch 8, the access of pulse photoelectricity instrument
Socket 9, power switch 10, tactile keyboard 11, printer interface.
It is measurement voltage referring to Fig. 3（Power supply）, electric current, pulse wiring diagram.Parts title is as follows：12nd, single-phase electric energy
Table, 8, pulse photoelectricity instrument measurement access, 13, load current forcipated mutual-inductor access, 14,220 volts of electric power incoming lines, 15, electric leakage electricity
Flow forcipated mutual-inductor access, 16, voltage measurement access, 17, load outlet.
This single-phase electric energy meter detection recorder can not only carry out whole item detections to electric energy meter, as measuring accuracy is surveyed
Fixed, experiment of having good luck, additionally it is possible to carry out power load record, effectively Electricity customers can be carried out with electricity consumption situation analysis, answer
Client's query, it is horizontal to improve good service.And detection of electrical leakage can be carried out, finds out customer electricity unexplained loss, is multi-functional
Comprehensive detecting Instrument.
On electric energy meter basis, more accurate instrument is manufactured and designed, has installed printer interface additional, installed additional negative
Charged current and leakage current measurement hook type current transformer, have carried out software programming.72 hours electric current, voltage, work(can be carried out
Rate, electricity record, can carry out accuracy detection and contrast test of having good luck, contrast test of having good luck is by the energy data of instrument record
With the energy data contrast of electric energy meter record.Solve single-phase electric energy meter on-site test problems, solve customer electricity situation
Problem analysis.
Detection of electrical leakage operation is as follows：Leakage current jaw type transformer is sandwiched simultaneously fire, the zero line of electric power incoming line, at this moment,
The electric current measured is the difference of live wire and neutral line current.Because in normal electricity consumption, the current value that is flowed through on live wire and zero line
Equal, in the opposite direction, its difference is zero.Under failure drain conditions, its value is not zero, during zero line grounding, the electric current that measures
It is worth small, when live wire is grounded, the current value measured is larger, and electric leakage has danger to human injury, so this is detected
It is significant.
To contrast test of having good luck：The energy data and electric energy meter indicated number that this recorder recorded are contrasted, and are judged
Correctly whether electric energy meter have good luck, so as to complete the experiment of having good luck to be carried out of code regulation.
Carry out accuracy detection：This instrument electric energy measurement precision is 0.2 grade, and the electric energy meter of onsite application is 1.0 grades or 2.0
Level, this accuracy of instrument two grades higher than tested electric energy meter, so measuring accuracy test can be carried out to electric energy meter.
It is described above, simply the embodiment of the present invention, various illustrations are not to the substantive content structure of the present invention
Into limitation.
