Description
Technical field
The utility model is related to a kind of quick systems for detecting whether power stealing.
Background technology
In power supply system, stealing electricity behavior is the larger behavior of harm, not only causes electric company's electricity loss of energy,
Can also give electric company's mistake electricity consumption data, the planning of supply line be caused to be slipped up, so as to bring transmission of electricity, distribution in terms of peace
Full problem.
Invention content
In consideration of it, the utility model provides a kind of quick system for detecting whether power stealing, can quickly detect whether to steal
Electricity, and will not give and be detected the interference that user brings normal electricity consumption.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows：One kind quickly detects whether to sneak current
System, including power dial gauge, ammeter and the user equipment being connected between alternating current firewire and zero curve, power instruction
First end, second end, the first end of ammeter, second end and the user equipment of table are sequentially connected in series, the power dial gauge first
End also connect with the zero line side of the second end of the ammeter by a shunt line, be provided on the shunt line shunt resistance and
First switch, the system further include an alternator indicator, and the alternator indicator is connected to the power by a second switch
The first end of dial gauge, the alternator indicator is also connected to the first end of the user equipment by third switch, described
First switch, second switch, third switch are normally open, and the voltage between shown firewire and zero curve is AC 220 V.
If user has stealing electricity behavior, the electric current of user equipment can be less than the electric current between alternating current firewire and zero curve, pass through
In turn be closed second switch, third switch, if the current difference that alternator indicator flows through twice is larger, alternator indicator it is bright
Degree can then change greatly, you can find the stealing electricity behavior of user easily.After finding that alternator indicator brightness change is larger, in order to
It reaffirms the stealing electricity behavior of the user, the first switch can be closed, if the user has stealing electricity behavior, due to connecing for shunt line
Enter, pass through the reading amplitude of variation of readout power dial gauge, you can whether judgement user sneaks current.
Further, the resistance value of the shunt resistance is equal to the sum of resistance value of ammeter, power dial gauge.Due to shunt resistance
Equal to ammeter, the sum of the resistance of power dial gauge, then the reading of power dial gauge should be the half before first switch is closed, if with
There is stealing electricity behavior at family, then reading variation can be less than the half before first switch is closed.
Description of the drawings
Fig. 1 is the quick system schematic for detecting whether power stealing of the utility model.
Specific embodiment
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
Embodiment one
With reference to figure 1, a kind of quick system 100 for detecting whether power stealing, including being connected to alternating current firewire 110 and zero curve
Power dial gauge 130, ammeter 140 between 120 and user equipment 150, the first end of the power dial gauge 130, second end,
First end, second end and the user equipment 150 of ammeter 140 are sequentially connected in series, 130 first end of power dial gauge and the ammeter
The zero line side of 140 second end is also connected by a shunt line 160, and shunt resistance 170 and are provided on the shunt line 160
One switch 180, which further includes an alternator indicator 190, which is connected by a second switch 200
In the first end of the power dial gauge 130, which is also connected to the user equipment by third switch 210
150 first end, the first switch 180, second switch 190, third switch 200 are normally open, shown firewire 110 and zero curve
Voltage between 120 is AC 220 V.
In the present embodiment, which is equal to the sum of resistance of the ammeter 140, the power dial gauge 130.
If user has stealing electricity behavior, the electric current of user equipment 150 can be less than between alternating current firewire 110 and zero curve 120
Electric current, by being closed second switch 200, third switch 210 in turn, if the current difference that alternator indicator 190 flows through twice
Larger, the brightness of alternator indicator 190 can then change greatly, you can find the stealing electricity behavior of user easily.
After finding that alternator indicator brightness 190 changes greatly, in order to reaffirm the stealing electricity behavior of the user, it can be closed
The first switch 180 if the user has stealing electricity behavior, due to the access of shunt line 160, passes through readout power dial gauge 130
Reading amplitude of variation, you can judgement user whether sneak current.Since the resistance value of shunt resistance 170 is equal to ammeter 140, power indicates
The sum of resistance of table 130, then the reading of power dial gauge 130 should be first switch 180 be closed before half, if user has power stealing
Behavior, then reading variation can be less than the half before first switch 180 is closed.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model principle is not departed from, several be suitble to can be done to the technical solution of utility model
The improvement of actual conditions.Therefore, the protection scope of the utility model is not limited thereto, and those of skill in the art are any based on this
Non-material change is included within scope of protection of the utility model in utility model technical solution.
