Problems solved by technology
[0002] In the daily power supply, it is not uncommon for some unscrupulous users to install interference devices in the metering device to steal electricity without authorization. After changing the metering device without authorization, the current flowing through the current coil is reduced, thereby achieving the purpose of stealing electricity, and from the lead It is not easy to directly determine whether there is an abnormality of useful electricity on the surface of the seal, meter box and meter, and the behavior of stealing electricity is not easy to be detected
It is time-consuming and labor-intensive to open the lead seal for inspection in a targeted manner, and it is impossible for thousands of households

The invention relates to an electricity stealing rapid diagnostic apparatus which is characterized by comprising current sampling modules, an A / D conversion module, an arithmetic unit and a display, wherein the current sampling modules are connected with the A / D conversion module; the A / D conversion module is connected with the arithmetic unit; the arithmetic unit is connected with the display; the current sampling modules comprise an input end current sampling module and an output end current sampling module; the input end current sampling module and the output end current sampling module are both connected with the A / D conversion module. According to the electricity stealing rapid diagnostic apparatus, when detection is carried out to an ammeter, a lead seal and an ammeter box are not required to be opened, detection to the ammeter can be carried out outside the ammeter box, the time and labor are saved, the speed is fast, an abnormal electricity consumer can be found timely, and the electricity stealing fast diagnostic apparatus has higher innovativeness.
Description
technical field [0001] The invention belongs to the field of power supply management equipment, in particular to a fast diagnosis instrument for electricity theft. Background technique [0002] In the daily power supply, it is not uncommon for some unscrupulous users to install interference devices in the metering device to steal electricity without authorization. After changing the metering device without authorization, the current flowing through the current coil is reduced, thereby achieving the purpose of stealing electricity, and from the lead It is not easy to directly determine whether the useful electricity is abnormal on the surface of the seal, meter box and meter, and the behavior of stealing electricity is not easy to be detected. It would be time-consuming and labor-intensive if the lead seals were opened without targeting, and it was impossible for millions of households. In response to this situation, based on the principle that the current of the power suppl...
