Abstract
The invention discloses the method for auto-breaking during a kind of intelligent electric energy meter stealing, described method mainly comprises following measure: increase a measure loop at the current measurement circuit of intelligent electric energy meter, measure loop precision is lower than measuring circuit, and numerical value is less than measuring circuit; It is doublewound sampling mutual inductor that electric energy meter for current transformer sampling adopts secondary, and the electric energy meter sample resistance for manganese copper diverter sampling should slightly larger than normal operating resistance; Measure loop enters primary processor and measuring circuit contrasts, if the numerical value that measuring circuit records is greater than measure loop, measure normal, if the numerical value that measuring circuit records is less than the numerical value of measure loop, then send signal by processor, drived control mechanism carries out power operation, and exports corresponding signal by reporting to the police.The present invention is expanded by the function of intelligent meter body, economical and practical, makes intelligent meter more intelligent, safe ready, can effective electricity theft prevention.
Description
Technical field
The invention belongs to anti-theft electricity technology field, be specifically related to the method for auto-breaking during a kind of intelligent electric energy meter stealing.
Background technology
Intelligent electric energy meter is a kind of novel electronic power meter, there is electric energy metrical, information stores and the various functions such as process, Real-Time Monitoring, automatically control, information interaction, support the actual needs such as bidirectional measuring, step price, tou power price, time-of-use tariffs, this intelligent electric energy meter has multiple communication modes, include infrared communication, power line carrier, public network wireless telecommunications etc., coming into operation of it significantly can change the Environment and Behavior of the current electricity consumption of people, is also convenient to the management of power use of power supply department.Along with the continuous progress of science and technology, various stealing technology emerges in an endless stream, and intelligent electric energy meter stealing also occurs often, in view of intelligent electric energy meter possesses above several functions, once wreck, will cause very large impact to whole electric power system.
Summary of the invention
The invention provides a kind of can the intelligent electric energy meter stealing of effectively electricity theft prevention, safe ready time auto-breaking method.
A method for auto-breaking during intelligent electric energy meter stealing, described method mainly comprises following measure:
A, increase a measure loop at the current measurement circuit of intelligent electric energy meter, measure loop precision is lower than measuring circuit, and numerical value is less than measuring circuit;
B, for current transformer sampling electric energy meter adopt secondary be doublewound sampling mutual inductor, for manganese copper diverter sample electric energy meter sample resistance should slightly larger than normal operating resistance;
C, measure loop enter primary processor and measuring circuit contrasts, if the numerical value that measuring circuit records is greater than measure loop, measure normal, if the numerical value that measuring circuit records is less than the numerical value of measure loop, then send signal by processor, drived control mechanism carries out power operation, and exports corresponding signal by reporting to the police.
The invention has the beneficial effects as follows: because the present invention is expanded by the function of intelligent electric energy meter body, economical and practical, make intelligent electric energy meter more intelligent, safe ready, can effective electricity theft prevention.
Embodiment
Below by specific embodiment, further illustrate advantage of the present invention:
A method for auto-breaking during intelligent electric energy meter stealing, described method mainly comprises following measure: increase a measure loop at the current measurement circuit of intelligent electric energy meter, measure loop precision is lower than measuring circuit, and numerical value is less than measuring circuit; It is doublewound sampling mutual inductor that electric energy meter for current transformer sampling adopts secondary, and the electric energy meter sample resistance for manganese copper diverter sampling should slightly larger than normal operating resistance; Measure loop enters primary processor and measuring circuit contrasts, if the numerical value that measuring circuit records is greater than measure loop, measure normal, if the numerical value that measuring circuit records is less than the numerical value of measure loop, then send signal by processor, drived control mechanism carries out power operation, and exports corresponding signal by reporting to the police.
The present invention is expanded by the function of intelligent meter body, economical and practical, makes intelligent meter more intelligent, safe ready, can effective electricity theft prevention.
