Description
Technical field
The utility model relates to a kind of intelligent electric meter expense control device, is specifically related to a kind of intelligent electric meter expense control device that can Long-distance Control intelligent electric meter user power utilization loop.
Background technology
Intelligent electric energy meter has compositions such as measuring unit, data processing unit, communication unit, has functions such as electrical energy metering, data processing, monitoring in real time, control automatically, information interaction.Intelligent electric meter is many at present is used with external on-load switch (isolating switch); The external on-load switch (isolating switch) of existing use only possesses functions such as conventional traffic overload, open circuit fault protection and complete electrical isolation; Do not possess the intelligence of to receive and show the control signal of sending and the function of cutting off the power supply automatically, can't realize the Long-distance Control power down function of intelligent electric meter.
Summary of the invention
To the problems referred to above, the utility model provides a kind of intelligent electric meter expense control device that can realize the Long-distance Control power down function.
The purpose of the utility model is achieved in that a kind of intelligent electric meter expense control device that the utility model provides; Comprise have measuring unit, intelligent electric meter that data processing unit, communication unit, power consumption metering show and the external on-load switch of supporting installation with it; It is characterized in that: also be provided with built-in relay in the said intelligent electric meter; Said external on-load switch is provided with shunt release and operation circuit; The combined floodgate of said external on-load switch and disconnection are controlled by shunt release and operation circuit; Said built-in relay outputs control signals in the operation circuit on the external on-load switch with Chang Kai or normally closed two kinds of different conditions, external on-load switch is in allows to close a floodgate or two kinds of different conditions of instantaneous trip.The principle of work of the utility model is: shunt release RL1 has or not through operation circuit voltage, thereby the break-make of control solenoid reaches the purpose of shunted exciter tripping work. when control circuit is switched on, and can the reliable closed closing position that also remains on for a long time.When control circuit broke off, time-delay was broken off in 0.5s to 2s.The utility model adopts technique scheme; When normal electricity consumption of ammeter user or full-amount electricity payment; Main website sends close command through local mode or remote mode; After this relay closes, external on-load switch control loop through closure obtained low-voltage signal, external on-load switch was in the permission "on" position; When the ammeter user is in the arrearage state; Main website sends open command through local mode or remote mode; The built-in relay of intelligent electric meter breaks off, and external on-load switch control loop breaks off, external on-load switch tripping operation; And being in can not "on" position, and the back of promptly forcing to close a floodgate instantaneous trip will take place at once.
The general selection of above-mentioned relay is in normally open, output control signal when built-in relay is in closure state, and external on-load switch obtains low-voltage signal through the control loop of closure, makes external on-load switch be in the permission "on" position; No-output control signal when built-in relay is in off-state, the control loop of external on-load switch does not have low-voltage signal, makes external on-load switch be in the instantaneous trip state.
The preferred scheme of above-mentioned control signal is for adopting ac sinusoidal voltage signal, its effective value 220V, frequency 50Hz.
The utility model is threaded off by the single-phase control intelligent electric meter may command shunt opening that takes.During operate as normal, intelligent electric meter output control signal, external on-load switch maintains "on" position, allows user power utilization; When satisfying controlled condition, ammeter breaks off the control signal of output, and external on-load switch should break off and keep off-state; Interruption of power supply, and break off during the control signal external on-load switch can not manual closing operation, realized the intelligent electric meter Long-distance Control; Manpower and materials have been reduced; Evade security risk, reach the purpose of the conscious electricity payment of user, effectively promote these district's electricity charge to reclaim.
