Direct stealing of electricity is illegal, but there are several ways to reduce electricity consumption. In some places, high power is not required. Try not to use it. For example, street lamps, bathrooms, bedrooms, etc., try to use energy-saving lamps, transform lines, and collect line losses. Increased power factor, even telephone lines can be used for lighting, of course, requires a bit of technology. According to many cases of tampering, the thief is mostly started from the metering device. Because the metering box is concealed and difficult to be found, it must be meticulous as an anti-stealing person. The electric energy meter measures the electric quantity by the product of the three factors of voltage, current and power factor and time. Therefore, changing any one of the three elements can make the electric energy meter slow, stop or even reverse.
1. Talking about stealing electricity from the structure of the meter. I know that the meter has four terminals, from left to right, one, two, three, and four. One of them is the current coil one and the third is the voltage coil. There are two conditions for the rotation of the meter: there is a current in the current coil, and there is a rated voltage across the voltage coil.
There is a method for making it non-rotating: there is a small piece between the two terminals, and the movable piece can be loosened by a screw that fixes one end, and they are separated, that is, the voltage is disconnected. The voltage of the coil, the watch will not move. Of course, this is the easiest and most easily discovered, too obvious.
Method 2: The standard watt-hour meter wiring is the No. 1 terminal connected to the live line, and the third line is connected to the zero line. We know that the connection between the three and four is as long as the fire line is connected to three, the zero line is connected to one, and at the same time, a reliable ground wire is made at home, and the original zero line is disconnected, which is usually said to be a fire. Ground, the table will not move, I want to let it move when the zero line is restored. The characteristic of this method is concealed and simple. If you are afraid of being found not to move for a long time, you usually connect a small power bulb between the zero fires at home, so that you can't see it from the outside. To find it difficult, because there are too many users, it is impossible to open the check box.
Prevention method: Install the leakage protector. As long as someone uses this method, the leakage protector will trip. However, the leakage protector is too easy to break or be broken.
2. From the structure of the electricity meter, the general practice of stealing electricity is to open the meter box. The method should be a lot. I mainly talk about the modification methods of several meters. 1. Change the gear ratio of the counter. Generally, the counter worm output. The pinion gear, the number of teeth is not much, can be smashed according to the ratio you want to reduce. This method may have a phenomenon of biting teeth. It is more reliable to use a table with a high number of revolutions, such as 2100 rpm / KWH, Its counter replaces the counter with low number of revolutions, such as 720 rpm / KWH, then the count is 1/3 of the actual power. Of course, pay attention to the best size of the counter to be natural.
Second, use a length of about 15 cm enameled wire, the thickness and current coil are the same, from the inside of the table and on the current coil, so the counter number is about 1/10 of the actual power, if the power consumption is not large and not concentrated, you can Try the magnetic clearance adjustment screw in the watch. When the load is empty, the watch will slowly fall back, which is about 15W.
Attached to the problem of the seal. Use a small screwdriver or a needle to repair the clock, carefully follow the line in the seal to slowly expand, it is not too difficult to extract it, and finally put it back when loading Seal with a flat-nose pliers and do not damage the writing on it.
3. Continue to talk about stealing electricity from the structure of the meter
I used to talk about the common method of stealing electricity from ordinary electricity meters. This time I introduce another one.
First of all, people who use this method must have the necessary electrical foundation to be flexible. If they understand the principle, they can be used even more on the high-current watt-hour meter with transformer.
According to the principle of the watt-hour meter, the current coil consumes a part of the energy during normal operation, and there is a voltage at both ends, depending on the current. This method is to take advantage of this.
Prepare a self-twisting transformer with a capacity of not less than 2KVA, too small to burn out and have poor effect. The secondary voltage requires 3~8V, on the three terminals of the transformer ("0" line end, common side, secondary side ), connect an active plug to the "0" line and the common terminal. (The SD terminal must be free of errors.) Make the voltage of the other end of the secondary line and the "0" line lower than the voltage of the common terminal. (If not, replace the secondary tap. can).
When using, be sure to insert the plug into the correct position, that is, the common end is connected to the live wire. The other end of the secondary end is connected to the fire line at a position before the meter with a long enough wire. Be careful not to cause personal injury in the order of wiring!
Since the current coil is reversed, the meter will run in the opposite direction. Depending on the secondary voltage, the speed is 2~5KWH. With this method, all the connectors in the circuit must be in good contact, otherwise the effect will be affected. (may not be negative)
As for the IC-type watt-hour meter, you can combine the previous introductions. As long as you understand the principle, there should be no problem.
The principle mentioned above is good! But only for DT862, DD862 and the following types of energy meters!
The electric energy meter has overcome the above disadvantages in terms of anti-theft.
1. In the mechanical electric energy meter, some non-return devices have been installed on the turntable, and the maximum number of turns of the electric energy meter will not exceed one turn.
2, in the electronic energy meter, no matter how you change the position of the fire line, the zero line, the table still reads. In some large-scale meter and three-phase meters, there is even a phenomenon in which the metering of the reverse wiring is multiplied. Effectively prevent malicious mess.
to sum up:
1. Ground the neutral wire of the appliance directly without flowing through the energy meter. In this way, you use more electricity, the meter does not move. Disadvantages: Once a person touches the grounded zero line, it immediately dies; when someone checks the meter, it may find that "the electric light is on, the meter does not turn", you hang up.
2. Since the turntable in the electric meter is rotated by the force of the magnetic field eddy current, a magnet can be installed next to the electric meter to generate a diamagnetic field to partially cancel the magnetic force. The downside: When someone checks the meter, if you find a big magnet on your meter, your stealing behavior will be revealed.
3. Short the meter. The disadvantage is the same as 1.
4. Connect a resistor with a suitable resistance in parallel with the meter. This can avoid the phenomenon that "the electric light is on and the electric meter does not turn", but the installation is difficult, and the parallel resistance is easy to burn.
5. Use a special tool to disassemble the meter and dial the counter. The downside: high technical requirements, very troublesome. (If everyone does this, the telecommunications bureau should go bankrupt)
Final tip:
The first step is to directly adjust the meter or the meter wiring to open the meter cover and directly transfer the speed of the ××× limit table. Or do not connect the meter, direct lead.
Consequence: Cause the meter to stop or go slowly. If you share a total meter, it will cause losses to other users.
The second trick wire stealing wire is inserted inside the meter box.
Consequences: The internal structure of the wire breakage watch stops the watch. If an electric shock occurs, the thief is the most direct victim.
The third measure was purchased by the unscrupulous trader in the hands of the dealer, causing the meter to reverse.
Consequences: Electricity consumption and rated power are very large, sometimes even negative, causing losses to the power sector or neighbors.
The fourth step is to reverse the connection of the wires connected to the meter, and reverse the phase or two-phase current ×××.
Consequences: There are security risks, causing the meter to reverse or not.
The fifth measure: the private meter is connected to the power line without wires, and the untested power meter is installed.
Consequences: The danger of connecting high-voltage electrodes privately, the power sector suffers huge losses.
The sixth measure: disconnect the meter using the micro AC contactor to disconnect the metering expression to steal the purpose. Using three-phase compensation capacitors, disconnecting ××, and only accessing ×××××, causing the meter to reverse.
Consequences: A threat to personal safety and a huge loss to the power sector.
The seventh trick: direct lead to the meter line directly into the ground. Ground the cable privately, then install the knife gate and lead the power supply to the large transformer through the ground cable.
Consequences: When the operation is wrong, the overloaded electricity causes a short circuit, the electric wire is burnt or even causes a fire or the electrical appliance is destroyed.
The eighth measure: the metal object insert table is inserted into the meter with the aluminum alloy sheet or the steel needle. It is not easy to see the appearance, and a small hole is placed above the meter, and some also block the hole with white ash. Some people tied the metal sheets with ropes.
Consequences: causing the meter to slow down or stop moving. The country’s power losses are serious and pose a threat to the safety of thieves.
The ninth trick: the private temporary wire is exposed, and the connection is not standardized.
Consequences: Unsafe, sparks often appear at the interface. The power sector or neighbors suffered losses.
The tenth trick: privately build cable wells to build cable wells privately. The cable lines are buried underground and always connected to the transformer.
Consequences: Wire wrapping is not standardized, and it is easy to short-circuit due to moisture, resulting in large-scale power outages. It caused huge losses to the national power.
The eleventh trick to use the pipeline to lead to electricity is mostly a temporary electricity that is illegally connected. Wire connections are not standardized, and some even conduct electricity through tap water pipes.
Consequences: The danger is extremely high, and the charged pipeline always threatens people's lives.
The twelfth move to transform the current transformer by winding × ×, generate eddy current, causing the meter to stop.
Consequences: threatening human security and the power sector suffers losses.
The thirteenth electric charge card key illegal recharge appearance is difficult to identify. It is necessary to be proficient in electronic knowledge and increase the amount of electricity used through illegal channels, which can be detected by professionals.
Consequence: causing losses to the national electricity.
The fourteenth move increases the electricity capacity and increases the electricity consumption without authorization, and increases the electricity consumption such as the measurement ratio.
Consequence: Loss of electricity costs.
