Description
[technical field]
The present invention relates to a kind of anti-electricity-theft ammeter, especially relate to a kind of anti-electricity-theft structure of ammeter in a row.
[background technology]
Electric energy has production as a kind of special commodity and carries out and have not have visible characteristic in kind with use simultaneously.For making electric energy on intermediate links, not cause dead wight loss, power supply department will be carried out the management work of each side usually, particularly anti-electricity-theft strike aspect.Show according to numerous stealing cases; Stealing is started with from ammeter " WT-MSR " mostly; Because tool is disguised in the ammeter box, be difficult for found characteristics, main what take precautions against is the product decision etc. of voltage, electric current, power factor three elements and the time of ammeter metering electric weight so oppose electricity-stealing; Therefore, electricity filching person change in three elements any one can make ammeter slow-speed, stall even counter-rotating.
The common stealing mode of finding in daily the patrolling and examining roughly has following several kinds:
One, changes the current coil of short circuit WT-MSR.Normally at ammeter inner or outside with lead with the current coil short circuit, more common way be with lead or and connecting resistance insert the phase line input end and the output terminal of ammeter, play shunting action.Use the lead short circuit, and conductor resistance is zero no better than, most electric currents will pass through from the short circuit lead, and the current coil of ammeter does not almost have electric current, causes the ammeter stall; And if when connecing the resistance less than the current coil resistance value, current coil with and connecting resistance form parallel circuit, according to the shunting principle of parallel circuit; Most of electric current will from and connecting resistance pass through; Current coil has only little electric current to pass through, and causes ammeter slow-speed by a certain percentage, thereby reaches the stealing purpose.This kind stealing mode is referred to as the stealing of undercurrent method.
Two, off voltage joins the sheet or the divider resistance of on potential winding, connecting; The off voltage coil makes the potential winding decompression cause ammeter not change exactly.Common methods is to unclamp the voltage plate of ammeter, and this method needn't game clock be sealed, and belongs to more rudimentary stealing electricity method, and novel ordinary electric meter joins sheet at the inner short circuit of ammeter.They are two years old; Opening the ammeter enclosing cover is connected on the potential winding with a resistance string; Institute's series resistor entangles (having disguise) with insulating tape or insulating sleeve, and its principle is to play the dividing potential drop effect, shares the resistance two ends to a part of voltage; The potential winding voltage is reduced, reach the purpose of few quantity calculation.This type of mode also is referred to as under-voltage method stealing.
Three, transfer zero live wire stealing; This stealing electricity method is prior fire, zero line transfer with the ammeter end of incoming cables; Internal circuit configuration according to ammeter; The input of connecting to neutral line end is to use to join the sheet short circuit with output, and therefore, the stealing family is capable of using from the zero line electricity consumption of establishing (or connecing in addition); And ammeter causes the ammeter stall because of there not being the current coil of reciprocal current return through ammeter.This stealing electricity method must be at indoor installing back brake CS, makes through the zero line of ammeter and establishes ground wire (or connecting to neutral line) in addition certainly and can control freely.But establishing ground wire certainly brings serious threat can for the user's security electricity consumption.
Four, disconnected zero stealing; This stealing electricity method must break off the zero line of ammeter end of incoming cables in advance and it is hidden.Similar with the stealing of transfer method, all need connect or establish certainly ground wire in addition, and at indoor installation back brake switch.After breaking off ammeter input zero line, current coil still can pass through electric current, and potential winding can lose voltage, at this moment, the electricity consumption of stealing family, ammeter can not measure.When the stealing family thinks that ammeter rotates metering, can be from ammeter zero line output terminal reversal connection zero potential (be other connecting to neutral line or establish ground wire certainly), potential winding obtains voltage, and ammeter rotates.Its two, series resistor on the lead of reversal connection zero potential, with under-voltage method similar, play few quantity calculation effect.This type of mode also is referred to as disconnected zero method.
Five, change counter gear.Its specific practice is a register of changing the high capacity ammeter with the register of low capacity ammeter, and the actual power consumption of electricity ratio that the ammeter meter after being replaced goes out reduces at double.Such as; Change the register of 10 (20) peace 900r/kWh with the ammeter register of 5 (10) peace 1800r/kWh; Because the current coil of ammeter and potential winding do not become, aluminium dish rotating speed is constant so, is once changeing the actual electricity consumption of meter but register is replaced back former 900; Become commentaries on classics 1800 commentaries on classics and just once counted, the actual power consumption of metering electricity ratio reduces half.The main points of this stealing electricity method are to use the ammeter of same producer can exchange register, otherwise mechanical dimension can't be corresponding.And adopt this method stealing primary to close is exactly will unlatching table meter seal " lead sealing ".But the Electric meter seal that present power supply department is adopted all is new-type seal, has anti-electricity-theft preferably performance.
Carry out stealing by aforesaid way, all be unable to do without the inner change of ammeter bottom or ammeter, that is to say, it is not moving by the people that the weakness of stealing is how to control ammeter.
[summary of the invention]
In order to overcome the deficiency in the background technology; The present invention discloses a kind of anti-electricity-theft structure of ammeter in a row, and the present invention is provided with inserting column through the both sides at ammeter in a row, is buckled in the ammeter bottom that goes wrong easily by " L " shape plate; Open " L " shape plate in case there is the people to destroy seal; Power supply department can find in time that just the present invention can realize the further anti-electricity-theft of ammeter, has effectively stopped the generation of the private road stealing electricity phenomenon of relocating.
