Its technical scheme is: a kind of intelligent high-pressure is purchased electric metering device in advance, is made up of the centralized computer of high-pressure vacuum breaker, current transformer, voltage transformer, prepayment meter, electricity load management terminal and main website of control centre; Electricity load management terminal comprises data acquisition controller and the data collector module that a single-chip microcomputer is a core; Data acquisition controller has the watchdog circuit that cooperates with management software to be connected; Current transformer, voltage transformer and prepayment meter are connected with data acquisition controller by the RS485 interface; Data acquisition controller connects door of meter casing transducer and voltage transformer respectively by the state acquisition interface; Data acquisition controller also connects electric operator control high-pressure vacuum breaker by the control output interface; The centralized computer of main website of above-mentioned control centre connects one or more centre data transceiver modules; Rely on the TCP/IP host-host protocol to carry out data communication by the GSM/GPRS network between the data collector module of electricity load management terminal and the centre data transceiver module of main website of control centre.
For the data communication of the centralized computer that guarantees electricity load management terminal and main website of control centre is not interrupted by fault; Be connected with reserve battery on the power supply of above-mentioned electricity load management terminal.
High-pressure vacuum breaker of the present utility model is the executive component that cuts off and connect main circuit, current-voltage transformer measures by the electric weight that secondary coil and no-load voltage ratio counting circuit are consumed, the pre-enough electric situations of pre-paying kilowatt-hour meter reflection can realize hanging down the signal output that electric weight is reported to the police and owed electricity charge tripping operation.
The utility model passes through electricity load management terminal, electric weight is gathered calculating, control and management, have earlier pay dues, the back electricity consumption, do not have and take the outage of prompting back, not only available IC-card control also can realize GPRS/GSM remote control, remote signalling and remote measurement, realize overcurrent and fast tripping protection, in time cut off the function of load current; Whole device does not have the energized conductor of exposing, and has good anti-stealing electricity function.But both VD4 vacuum circuit-breakers of adapted ABB AB, but the homemade VSI type vacuum circuit-breaker of adapted again.It is a kind of electricity distributing and metering device of superior performance.Have following advantage:
1. accurately metering: 0.2S current transformer, 0.2 step voltage instrument transformer and prepayment meter are adopted in metering.
2. forward purchasing electric work energy is arranged: special-purpose VS I circuit breaker is installed in the prepayment meter of the present utility model is used for the forward purchasing electricity, the forward purchasing electricity can be realized simultaneously by dual mode.First kind of implementation: the data of gathering with electricity load management terminal are as foundation, realize the breaker tripping and closing function of rationing the power supply by electric operator control high-pressure vacuum breaker.Second kind of implementation: the special-purpose VSI circuit breaker in the prepayment meter is directly realized the breaker tripping and closing function of rationing the power supply.
3. realize power supply management in order: when country needs the supply of electric power plan to supply with, can control electricity load management terminal, realize distant place power cuts to limit consumption by Data Communication in Computer Networks.
4. set up and far copy and monitoring management: make a copy of management of power use Various types of data and analyze, can carry out data such as quality of voltage, power consumption to the client and analyze, reach the purpose of remote monitoring.
