Figure.Aufsichtsrat can detect target line by following three kinds of modes, with judge user whether stealing and stealing
Stealing type.Wherein, detection mode one, two, three can make aufsichtsrat judge user whether stealing, detection mode
Two, three can make aufsichtsrat judge the stealing type of judgement stealing.The portable detection device of opposing electricity-stealing includes three
Current detecting part 20 and 4 voltage check part 50, current detecting part is Rogowski coil.
Detection mode one
As shown in Figure 3a, aufsichtsrat can first click 80 opening device of (namely switch operation) switch key, then supervise
The personnel of examining can be with long-pressing 10s (namely calibration operation) switch key 80, and device is calibrated in response to the operation.Then watchdog
Three Rogowski coils can be separately mounted on the connecting line between bus and the ammeter at user scene by member, namely be installed respectively
In A phase line, B phase line, C phase line (namely target line), Rogowski coil is looped around on corresponding route, so that Roche
Coil can carry out current detecting.Aufsichtsrat also need for four voltage check parts to be connected to A phase line, B phase line, C phase line and
On the neutral conductor, so that voltage check part can carry out voltage detecting.
Then, aufsichtsrat can be according to the electricity consumption data shown in first display screen, and views in live ammeter
Ammeter electricity consumption data, it is determined whether there are stealing situations, it is assumed that the electricity consumption data that device detects is differed with ammeter electricity consumption data
Larger, the electricity more than connecting line under normal circumstances consumes, then can determine that stealing happens.For example, if in display screen
The power data shown in the electric energy or display screen viewed in the long-range ammeter on site of the energy data of display is much larger than existing
The performance number etc. viewed in the ammeter of field, can determine that stealing happens, user's stealing.
Detection mode two
As shown in Figure 3b, aufsichtsrat can use Rogowski coil and detect bus respectively and show when determining user's stealing
The A phase line between A phase line and live ammeter and user power utilization equipment between the ammeter of field, obtains A phase line scene ammeter two sides
Current data, namely obtain the current data I1 of A phase line and scene ammeter between bus and live ammeter and set with user power utilization
The current data I2 of A phase line between standby, if the difference between I1 and I2 is much larger than ammeter live under conventional sense and A phase line line
When the current drain on road, it can determine that user carries out stealing by A phase line.Similarly, aufsichtsrat can also be to B phase line, C phase line
It is detected, judges user whether with B phase line, the progress stealing of C phase line.
Detection mode three
As shown in Figure 3c, aufsichtsrat to bus and can also be used when determining user's stealing using a Rogowski coil
A phase line, B phase line, C phase line and four routes of the neutral conductor (or zero curve) between the ammeter at family scene carry out electric current inspection simultaneously
It surveys, and/or, using a Rogowski coil to A phase line, B phase line, the C phase line between live ammeter and user power utilization equipment
With the neutral conductor carry out current detecting, if detecting, current data is not zero, if current value is larger, then can determine user pass through by
Electric current is only accessed into A phase line, B phase line, the mode of C phase line (namely electric current not being accessed the neutral conductor) and carries out stealing.
In this way, aufsichtsrat can use portable detection device of opposing electricity-stealing, target is quickly and accurately detected at the scene
The electricity consumption data of route, and determined whether there is surreptitiously according to the ammeter electricity consumption data that the live ammeter of electricity consumption data and user is shown
Electric situation, and stealing type is determined according to electricity consumption data.
The above, the only specific embodiment of the disclosure, but the protection scope of the disclosure is not limited thereto, it is any
Those familiar with the art can easily think of the change or the replacement in the technical scope that the disclosure discloses, and should all contain
It covers within the protection scope of the disclosure.Therefore, the protection scope of the disclosure should be based on the protection scope of the described claims.
