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: Such as figure 1 As shown, an on-site rapid anti-electricity stealing tool based on meter indication and verification includes a clamp-on current transformer, a standard electric energy meter connected to the clamp-on current transformer, and a programmable controller connected to the standard electric energy meter.

[0028] An on-site rapid anti-theft tool to detect electricity theft based on meter display and verification, including the following steps: a clamp-on current transformer is clamped on the incoming line of the meter under test, and a programmable controller displays one in time T Degree display a1, accurate to 0.01 degrees (because the customer's meter display shows two decimal places), and input the initial degree display a of the measured meter at the same time. The degree display a is greater than the current degree of the measured meter. When the indicator reaches a, the standard electric energy meter is connected with the clamp-on current trans...

Embodiment 2

[0035] Such as figure 2 As shown, an on-site rapid anti-electricity stealing tool based on meter indication and verification includes a clamp-on current transformer, a standard electric energy meter connected to the clamp-on current transformer, and a programmable controller connected to the standard electric energy meter.

[0036] The programmable controller is connected with a precise calculation 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.

[0037] The high-speed camera and the metering box are fixed by a clamping mechanism.

[0038] The clamping mechanism includes a G-shaped clamp and a connecting rod connected with the G-shaped clamp through a universal ball head, and the connecting rod is movably connected with a high-speed camera.

Abstract

The invention discloses an on-site rapid electricity-stealing-prevention tool and an electricity-stealing detection method thereof based on ammeter degree verification. The on-site rapid electricity-stealing-prevention tool comprises a split-core-type current transformer, standard electric energy meters connected with the split-core-type current transformer and a programmable controller connected with the standard electric energy meter. The programmable controller is connected with an accurate calculating device; and the accurate calculating device comprises 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 power system anti-theft equipment, in particular to an on-site quick anti-power-theft tool and a method for detecting power-theft based on the indication and verification of an electric meter. Background technique [0002] With the popularization and application of electronic watches, the current stealing tactics of power thief are gradually escalating. There are endless power stealing tactics for electronic watches. One of the more extensive stealing tactics is to change the electronic components in the electronic watch to make the meter Go slow, one of the more high-tech and more powerful methods of this kind is: do not change the meter constant (the number of turns of the turntable or the number of pulses and pulse strobe of the electronic meter), only change the counting display, and less power. The consequences of this are very serious and difficult to verify. The principle of less metering: the electric...
