If the deviation is too large, it can be determined that the meter is abnormal, and the inspectors can further verify the method of electricity theft to prove the illegal fact of electricity theft.

When the battery pack has insufficient energy storage, the two inner sliding contacts are horizontally moved to both sides of the battery pack, and at the same time, a 220V power supply is connected through the positive and negative electrodes of the needle probe to charge the battery pack 16 for next use.

In actual application, the first step is to install the LED signal light 10 at the center of the lamp 11, and then fix the lamp 11 to the device base 17 through the lamp clamping terminal 12, and the LED signal light 10 is connected to the outer sliding contact 131.

After the above components are assembled, the use process of the charge-discharge type low-voltage rapid electricity theft identification device is as follows:

In normal power usage, the power supply side power line 1 is installed at the incoming end of the three-phase four-wire air switch 2, and its outgoing end is connected to the incoming end of the joint junction box 3. The single-household lead-out line 5 at the outgoing end of the joint junction box 3 is fixed to the joint junction box 3 through the single-household wiring terminal 4. At the same time, the incoming live line 25 and the incoming neutral line 26 are respectively connected to the A and C incoming ports of the single-phase electric energy meter 7 through the wire wiring tube 9, and the B and D outgoing ports of the single-phase electric energy meter 7 are connected to the outgoing live line 28 and the single-phase electric energy meter neutral line 8, and then connected to the single-phase air switch live line terminal 29 and the single-phase air switch neutral line terminal 30 at the incoming end of the single-household air switch 6 through the wire wiring tube 9, and the outgoing line at the lower end of the single-household air switch 6 is connected to the customer's power load.

When checking whether the customer has committed electricity theft, the inner sliding contact is moved to a position close to the lamp, and the two outer sliding contacts are short-circuited with the two inner sliding contacts respectively.

Disconnect the single-family air switch 6, and make the positive pole 19 of the needle probe reliably contact with the live wire terminal 29 of the single-phase air switch; make the negative pole 20 of the needle probe reliably contact with the neutral wire terminal 30 of the single-phase air switch; at this time, the LED light 10 in the lamp 11 lights up, and can also illuminate the surrounding environment for easy operation.

By observing the number of flashes of the energy meter pulse indicator light 27 on the single-phase energy meter 7 , the counter button 22 on the counter 21 is pressed to count, and the data is read through the counter reading window 23 .

According to the rated power value of the LED light 10, the power consumption per second (or per minute) is converted, and then the number of pulse strobes per degree on the nameplate of the single-phase electricity meter 7 is converted into the number of strobes per second (or per minute). The number of strobes of the pulse indicator light 27 of the normal single-phase electricity meter 7 per second (or per minute) when the LED light 10 is on is estimated as the approved reference value.

Compare the difference between the data read from the counter reading window 23 and the approved reference value, and make a judgment based on the number at the end of the electric energy display window 24. If the deviation is too large, it can be determined that the meter is abnormal. The inspector can further verify the method of electricity theft to prove the illegal fact of electricity theft.

Repeat the above steps for other meters in the metering device to check whether the meters are operating normally.

In the case of power outage for maintenance, the inspector can move the two inner sliding contacts to the two sides of the battery pack, connect the positive and negative electrodes of the needle probe to the A and C incoming ports of the single-phase electric energy meter, and use the battery pack 16 as a power source to supply power to the single-phase electric energy meter 7. Remove the lamp 11, move the outer sliding contact 131 on the lamp 11, and make it reliably connected to the single-phase air switch live wire terminal 29 and the single-phase air switch neutral wire terminal 30 at the upper incoming end of the single-family air switch 6, and light up the LED lamp 10. In the same way, compare the number of times between the data read in the counter reading window 23 and the approved reference value. If the deviation is too large, it can be determined that the meter is abnormal, and the inspector can further verify the method of electricity theft to prove the illegal fact of electricity theft.

When the battery pack 16 is insufficiently stored, the two inner sliding contacts 132 are moved to both sides of the battery pack 16, and a 220V power supply is connected through the positive electrode 19 and the negative electrode 20 of the needle probe to charge the battery pack 16 for next use.

The lamp 11, battery pack 16, counter 21, etc. involved in this patent application are well-known and commonly used technical contents in the field, and ordinary technicians in this field can purchase them on the market or assemble them by themselves according to requirements.
