The utility model adopts the automatic test and calibration device and does not need human intervention, so that hours spent by two or three staff to complete certain workload can be reduced to only about an hour without man-hours, thereby saving labor and cost; and the utility model reduces error, improves accuracy, and has good economic value.
Description
Technical field
The utility model relates to that a kind of power quality analyzer is automatically examined and determine, calibrating installation.
Background technology
At present, the user who implements quality of power supply on-line real time monitoring and analysis is more and more, and is more and more urgent to the needs of the calibrating of power quality analyzer, calibration.Power quality analyzer is requisite in the work of the detection quality of power supply as the core instrument of the calibrating quality of power supply.Whether the duty of power quality analyzer is normal, is the emphasis of Power Quality Detection work.
And calibrating, the calibration of power quality analyzer also just seemed very important.Calibrating, calibration to power quality analyzer all was to adopt manually calibrating, calibration in the past.Manual work needs a plurality of staff's costs to carry out in several hours at least, and workload is big, makes a fault easily, and the error of calibrating, calibration is bigger, is difficult to satisfy the demand in present market.
Summary of the invention
The utility model provide a kind of full-automatic, little, the consuming time few novel power quality analyzer of error is automatically examined and determine, calibrating installation.
A kind of power quality analyzer is automatically examined and determine, calibrating installation, comprises a power quality analyzer, a power quality analyzer calibrating installation, a signal processing apparatus, connects by communication interface mutually between the three.Like this, signal processing apparatus can be controlled calibrating installation by communication interface, can set data such as alternating voltage, electric current, first-harmonic, harmonic wave, a harmonic wave, the rapid drawdown that rises sharply, the output of control verification device is connected to the input end of power quality analyzer then, signal processing apparatus reads the data of tested power quality analyzer again by communication interface, carry out aftertreatment, reach the purpose of automatic Verification, calibration.
Preferably, described signal processing device is changed to computing machine, comprises a main frame, a display and mouse, keyboard etc., can carry out data processing, demonstration easily.
Preferably, described power quality analyzer calibrating installation (abbreviation calibrating installation) comprises signal generator module, power amplifier, signal acquisition module, signal processing module and interface module.Can realize power quality analyzer is carried out the collection and the calibration of data.
Preferably, described communication interface comprises network interface, USB mouth, RS232/RS485.
The power quality analyzer that the utility model provides is automatically examined and determine, calibrating installation adopts full automatic computing machine and calibrating installation, do not need manual intervention, make that have several staff to spend workload that a few hours finish only was reduced to needs about one hour, and do not need labor hour, saved manpower and cost; Reduce error, improved accuracy rate, had good economic worth.
Description of drawings
Fig. 1 is the electrical schematic diagram of the utility model embodiment;
Fig. 2 is the electrical schematic diagram of calibrating installation among the utility model embodiment.
Embodiment
With the embodiment of indefiniteness the present invention is done further explanation, explanation below.
A kind of power quality analyzer is automatically examined and determine, calibrating installation, as shown in Figure 1, comprises a power quality analyzer 1, a power quality analyzer calibrating installation 2, a computing machine 3, connects by the RS232/RS485 shown in 4 among Fig. 1 mutually between the three.
Wherein, calibrating installation 2 comprises a signal generator module 6, a power amplifier 8, a signal acquisition module 7, a signal processing module 5 and an interface module 10 as shown in Figure 2.Interface module 10 and computing machine 3 and power quality analyzer 1 communication, at first receiving computer 3 order of sending and be transferred to signal processing module 5 of interface module 10, signal processing module 5 produces the reference waveform signal and is input to signal generator module 6, further be input to power amplifier 8 again, carry out the back subsequent operation.And after signal acquisition module 7 collects the signal of power quality analyzer 1, feed back in the signal processing module 5, signal processing module 5 compares the reference waveform signal of this signal and interface module 10 transmission, and to output waveform revise, be input to signal generator module 6, and then power quality analyzer 1 revised by power amplification 6 backs.
Signal generator module 6 is realized the reference waveform that signal processing module 5 sends is revised, realize waveform flickering, rise sharply, rapid drawdown etc.Signal acquisition module 7 is then gathered data such as the electric current and voltage effective value, phase place, frequency, power of power quality analyzer, and the effective value of each harmonic, phase place, catch instantaneous voltage fluctuation and flickering, or the like, power quality analyzer 1 is carried out real-time monitoring, calibrating.Power amplifier 7 is realized the function of power amplification, is to realize easily.Also be provided with a storer 9, be used to store data.
Like this, 7 various data of gathering power quality analyzer 1 in real time of signals collecting mould, and feed back to signal processing module 5, signal processing module 5 compares this signal and standard signal, revise, be input to signal generator module 6, accept the control of computing machine 3 again, amplify, finally power quality analyzer 1 is calibrated through signal.
