Function, anti-theft function and other intelligent functions. The smart meter is an intelligent instrument with microprocessor application and network communication technology ...

AI Technical Summary

Problems solved by technology

[0004] There are three main reasons for the low efficiency of the replacement of the electric energy meter. First, the material performance of the secondary voltage and current wires of the electric energy meter is soft, and the efficiency of the wiring fastening method is low.

In the current business scenario, the secondary wiring of the electric energy meter adopts a single-layer insulation single-core 2.5mm 2 Copper wire with single layer insulation single core 4mm 2 Copper wire, the wire core material is soft, and the wiring method is to directly strip off the exposed wire end and connect it to the secondary terminal of the electric energy meter, and then fasten it with screws. Every time the electric energy meter is replaced, it needs to be assembled and disassembled repeatedly

Secondly, the wiring wiring lacks fixing devices, which is prone to wrong wiring problems

In the current business scenario, the wiring of the three-phase metering components of the electric energy meter is distinguished by insulating layers of three colors: yellow, green, and red. However, the identification of the voltage and current lines of the same metering component is not clear, and a meter installer is required. High attention to core 2.5mm 2 with 4mm 2 The difference in wire diameter is to verify the voltage and current lines, which can easily lead to the occurrence of wrong wiring, resulting in the consequences of short circuit of the voltage loop and open circuit of the current loop.

Finally, the voltage and current exposed wire ends lack insulation packaging measures when replacing the energy meter

In the current business scenario, when the energy meter is replaced, it is necessary to use insulating tape to seal the exposed wires of the voltage and current. The operation process is cumbersome, and it is easy to accidentally touch the wires, which will lead to the risk of short circuit of the voltage circuit and open circuit of the current circuit; and the risk factor of live assembly and disassembly High, the insulation packaging measures are delicate and complicated, which is not conducive to the actual business work of the power production department
