The invention provides a remote ammeter reading system and method, which do not depend on the Internet, is higher in safety and lower in cost, and do not need too much IP addresses and mobile communication account resources, as well as an intelligent ammeter adopted in the ammeter reading system. According to the invention, as the system does not depend on the Internet, network hackers can not easily invade the system, so that the safety is higher; meanwhile, IP addresses are not required too much, and a plurality of intelligent ammeters can be connected with one mobile communication account, so that the occupation of mobile communication account resources is less; and arranging a meter mobile communication module, such as a GSM (Global System for Communication) module on each intelligent ammeter is unnecessary, and the cost is lower.

The invention discloses an isolation distributor. The distributor structure comprises an input terminal, a power indicator, a body, an output terminal, a detection device and an installation base, wherein the body is connected with the installation base, the power indicator is arranged in the middle of the body, the output terminal and the input terminal are respectively installed at the upper endand the lower end of the input terminal, the detection device is connected to the top of the installation base and respectively connected with the output terminal and the input terminal, the detection device comprises an input indicator, an output indicator, a protection shell, an input end connecting wire, an output end connecting wire and a detection ammeter, the input indicator and the outputindicator are installed on the surface of the protection shell, and the input indicator is arranged above the output indicator. The invention has the advantages that: whether the contact is correct ornot is checked by utilizing the phenomenon of current increase of the input and output ends, so that workers can be reminded in time, errors are reduced, equipment works normally, and damage to the isolation distributor is avoided.
