Description
Technical field
The present invention relates to electrical safety field, particularly about a kind of current supply circuit supervising device and system.
Background technology
Also there is no at present the ripe real-time electricity consumption energy-consumption monitoring system in use both at home and abroad, this itself is the main contents that intelligent grid low pressure electricity consumption side needs emphasis investment construction.Its Main Means of electricity consumption energy consumption monitoring in the past completes by obtaining the active energy consumption that electric energy meter records in a period of time (Yi Yuewei unit often) scope exactly, and this mode of obtaining energy consumption data by copy reading electric energy meter has that real-time is poor, a series of shortcomings of high in cost of production obviously.
" the electricity consumption metering separate system " that starts at present to occur is all to adopt a large amount of electric energy meters of installing, and comes the long-range electricity consumption data that read to realize part in real time and metering separate by wired (RS485/PLC) or wireless (Zigbee/GPRS).
The shortcoming of said system is as follows:
Install in a large number electric energy meter additional and carry out metering separate, high, a large amount of function of cost is idle; Industry/business/civil buildings take the distribution box of being inserted in wall to carry out current supply circuit management substantially at present, because ammeter own vol is large, metering separate ammeter is installed on each loop and in engineered construction, substantially cannot be realized; Real-time Obtaining data difficulty is large, and the transformation of communication line and working service cost are high, under the prerequisite that ensures numerous communication node real-time properties, system self energy consumption is large, run counter to the original intention of energy-saving and emission-reduction; Be difficult to realize the descending control to each monitoring circuit.
