Problems solved by technology

[0007] At present, domestic on-site ammeter checkers, inspectors, and on-site calibrators only calibrate the metering wiring method and ammeter constant (that is, between the number of revolutions or pulses and the load), and cannot change the constant of the ammeter (the number of revolutions of the turntable or The pulse number and pulse strobe of the electronic watch), and only change the counting degree to show the power stealing method for on-site verification

Embodiment 1

[0027] Example 1: as figure 1 As shown, an on-site fast anti-electricity theft tool based on the calibration of electric meters includes a clamp-type current transformer, a standard electric energy meter connected with the clamp-type current transformer, and a programmable controller connected with the standard electric energy meter.

[0028] A method for detecting electricity stealing by an on-site fast anti-electricity-stealing tool based on the calibration of an electricity meter, comprising the following steps: a clamp-shaped current transformer is clamped on the incoming line of the electricity meter under test, and a programmable controller displays a Degree indicates a1, accurate to 0.01 degree (because the customer's meter indicates two decimal places), and input the initial degree of the meter under test to indicate a, and the degree indicates that a is greater than the current degree of the meter under test. When the degree of the meter under test is Indicates that a...

Embodiment 2

[0035] like figure 2As shown, an on-site fast anti-electricity theft tool based on the calibration of electric meters includes a clamp-type current transformer, a standard electric energy meter connected with the clamp-type current transformer, and a programmable controller connected with the standard electric energy meter.

[0036] The programmable controller is connected with a precise computing device, which includes a high-speed camera connected with the programmable controller, an arithmetic module connected with the programmable controller, and a display screen connected with the programmable controller.

Abstract

The invention discloses an on-site rapid anti-theft electricity tool and a method for detecting electricity theft based on the calibration of electric meter indications, which include a clamp current transformer, a standard electric energy meter connected with the clamp current transformer, and a Programmable Controllers. The programmable controller is connected with a precise computing device, and the precise computing device includes a high-speed camera connected with the programmable controller, an operation module connected with the programmable controller and a display screen connected with the programmable controller.

Description

technical field [0001] The invention relates to the technical field of electric power system anti-stealing equipment, in particular to an on-site fast anti-electricity-stealing tool and a method for detecting electricity-stealing based on the calibration of electric meter indication. Background technique [0002] With the popularization and application of electronic watches, the current stealing methods of electricity thieves have also been gradually upgraded. Slow down, one of the more high-tech and more powerful methods is: without changing the constant of the meter (the number of revolutions of the turntable or the pulse number and pulse stroboscopic of the electronic meter), only the counting degree is changed, and the amount of electricity is less. The consequences of this are very serious and difficult to verify. The principle of causing less metering: the electricity stealing molecule installs a digital module in the electronic meter, connects the pulse lamp and the ...
