Problems solved by technology
[0005] The base meter and the power line carrier communication module are directly connected with the common GND. Therefore, once a strong pulse or surge is injected into the base meter or the power line carrier communication module, the dangerous voltage or current will flow due to the common GND of the entire system. Through the relevant parts of the entire system, it will cause damage to the entire system; for example, when a strong pulse or surge is poured into the base meter, it will also be poured into the power line carrier communication module, which not only causes damage to the base meter, but also causes damage to the power line. The carrier communication module is destroyed, therefore, the loss caused by the damage is increased

The invention provides a power line carrier communication isolation device for an intelligent electric meter. The power line carrier communication isolation device for the intelligent electric meter comprises an outer shell, a power line carrier communication circuit and an isolation circuit, wherein the power line carrier communication circuit and the isolation circuit are installed inside the outer shell; the power line carrier communication circuit is electrically connected with one end of the isolation circuit; the other end of the isolation circuit is used for being electrically connected with a base meter of the intelligent electric meter. When the power line carrier communication isolation device is connected with the base meter, the base meter and the power line carrier communication isolation device are two independent devices and constitute the intelligent electric meter together. Therefore, when high power pulses or surges pour into the base meter, the power line carrier communication isolation device can not be damaged; meanwhile, when the high power pulses or the surges pour into the power line carrier communication isolation device, the base meter can also not be damaged, and accordingly the safety and reliability of the whole system are enhanced.
Description
technical field [0001] The invention belongs to the technical field of power line carrier communication, and in particular relates to a power line carrier communication isolation device for smart meters. Background technique [0002] Power line carrier communication is a communication method in which data is transmitted over distribution lines as the information transmission medium. Since the power line network is the network with the widest coverage at present, it has huge potential utilization value. [0003] At present, combining the power line carrier communication technology with the electric meter, a smart electric meter can be designed, so as to realize the effect of remote meter reading. Its working principle is: the base meter uploads the measured power data to the power line carrier communication module, and the power line carrier communication module converts the received power data into a signal format suitable for transmission on the power line; then transmits ...
