Description
One, technical field: the invention belongs to the anti-theft electricity technology field of power system transmission line, particularly a kind of anti-electricity-theft device of electric system transportation art.
Two, background technology:
For a long time, stealing electricity phenomenon is the problem that electric power enterprise is extremely paid close attention to always, and stealing not only makes national wealth sustain losses severely, and influences the economic benefit of electric power enterprise, but also brings a series of potential safety hazard and social concern, endangers huge.In recent years, some lawless persons make electricity filching behavior more and more hidden by the means of developing skill, and the difficulty that power supply enterprise is investigated and prosecuted is increasing, thereby has caused massive losses to electric power enterprise.Their electricity filching behavior mainly contains following five kinds of means:
1. under-voltage method stealing: electricity filching person adopts various means to change the normal wiring in electric energy meter metered voltage loop, causes the metered voltage loop fault, causes the potential winding decompression of electric energy meter or suffered voltage to reduce, thereby causes electric weight to be counted less.
2. undercurrent method stealing: electricity filching person adopts various means to change the normal wiring in metering currents loop, or causes the metering current loop fault, the current coil no current that causes electric energy meter by or only by the part electric current, thereby cause electric weight to be counted less.
3. shift to the method stealing: electricity filching person adopts various means to change the normal wiring of electric energy meter, or access and electric energy meter coil do not have voltage, the electric current of electrical communication, the specific connection of utilizing inductance or electric capacity that also has, thereby change the normal phase relation between voltage, electric current in the electric energy meter coil, cause electric energy meter slow-speed or reversing.
4. expand the stealing of difference method: electric energy meter is torn in the electricity filching person private open, by utilizing various means to change the structural behaviour of the inside of electric energy meter, cause the error of electric energy meter own to enlarge, or utilize electric current or mechanical force to damage electric energy meter, change the mounting condition of electric energy meter, electric energy meter is counted less.
5. there is not the stealing of table method: electricity filching person wiring electricity consumption on the circuit of power supply department privately, or have the table user to get rid of the table electricity consumption privately.
At above-mentioned phenomenon, in recent years, power supply enterprise and units concerned actively develop the technical research of the aspect of opposing electricity-stealing when strengthening power utility check and management, have mainly taked following several measures of anti-stealing electricity: adopt special-purpose batch meter or special-purpose electric energy metering box 1.; 2. sealing transformer low voltage leading-out terminal is to the conductor of measuring apparatus; 3. adopt the pick-proof lead sealing; 4. installing charge monitor; 5. select the active electric energy meter with anti-stealing electricity function for use; 6. install special-purpose metering cabinet, measuring screen and anti-electricity-theft substation transformer; 7. the multiplying power of choose reasonable measuring apparatus current transformer.
Though above measures of anti-stealing electricity has played certain containment effect to electricity filching behavior, its input cost in use is bigger, but also very limited to the stealing effect of the no table method of containment, stealing desire that can not blocking-up electricity filching person in full force and effect.
Three, summary of the invention:
The objective of the invention is at above shortcomings in the prior art, and the anti-electricity-theft device of a kind of electric system of research and design, the advantage of this anti-electricity-theft device is: it has reasonable in design, and equipment cost is lower, can effectively block the stealing desire of electricity filching person in the use.
Technical scheme is: a kind of anti-electricity-theft device of electric system, it is characterized in that it is by conductor, current/voltage sex change heap, current/voltage is initial pile also, special-purpose electric energy meter four parts are formed, conductor is piled the current/voltage sex change respectively, current/voltage is initial pile also, special-purpose electric energy meter is connected as a single entity, conductor in service is with 50 hertz of the low voltage power transmission circuit, the alternating current of 220V becomes the curtage of non-standard standard through current/voltage sex change heap, be delivered to also initial pile of current/voltage by conductor again, the curtage of non-standard standard by current/voltage also initial pile be reduced to 50 hertz, the alternating current of 220V or voltage form are transported to special-purpose electric energy meter metering back output through conductor again and use for the user.Current/voltage sex change heap is one or several functions that can have in unsteady flow, transformation and the frequency conversion form, current/voltage also initial pile equally also can be to have in unsteady flow, transformation and the frequency conversion form one or several, and is complementary with the function of current/voltage sex change heap.
Preferred one, the anti-electricity-theft device of described a kind of electric system is characterized in that: 50 hertz of the low voltage power transmission circuit, the alternating current of 220V are delivered to also initial pile of current/voltage through the DC current that current/voltage sex change heap becomes 220V, the DC current of 220V by current/voltage also initial pile be reduced to 50 hertz, the alternating current form of 220V and use for the user through special-purpose electric energy meter metering back output again.
