The test side of detection device is connected to user, and the signal output end of power direction detection device is parallel to the control terminal two of switch
End, the communication ends of power direction detection device are connected to intelligent electric meter controller by communication device.
The Power System Intelligent prevents unordered anti-power transmission device, instead of original intelligent electric meter, due to the route of user
It is bound to be connected to supply network through the invention, it is possible to invention is construed as the separation of supply network and user,
This intelligent electric meter is equipped with power direction detection device, and device effect is only exactly that detect the direction of power be by supply network stream
Supply network is still flowed to by user side to user；When power direction detection device detects that separation user side flow direction occurs and supplies
When the power in electric network direction, the control terminal of power direction detection device can export control signal, disconnect switch, to disconnect
Separation can guarantee the safety of supply network maintenance, avoid peril, power although user is made to have a power failure
Direction detection device can send message information to the control chip of intelligent electric meter by communication terminal while output controls signal,
Message information can be transferred to host computer by the connection of intelligent electric meter and host computer, make power grid control enterprise the meeting of scheduling system and
Shi get Zhi, and contacting with user carries out corresponding prompt and solves, and intelligent electric meter, switch and power direction detection device it
Between be attached by control line and power supply line, make each section installation and wiring it is very convenient.
The Power System Intelligent prevents unordered anti-power transmission device, switchs as active power flow control switch, wattful power
Rate power flowcontrol switch is mounted between power direction detection device and user, and the control terminal of active power flow control switch connects
It is connected to the another output of power direction detection device.Active power flow control switch is to control power by thyristor
The angle of flow detects that being flowed to by user side occurs in separation in power direction detection device to control the switch of power direction
When supply network, power direction detection device first can send control signal to active power flow control switch, pass through wattful power
Rate power flowcontrol switch changes conducting power angle, makes power that may only flow to user side by supply network, but user side flows to
The power in supply network direction can not be connected, and ensure that will not there is power flow direction supply network at separation, guarantee staff
In maintenance, it will not be charged on route, lead to dangerous generation；When power detection device is sent to active power flow control switch
After controlling signal, power detection device still can detecte power of user's effluent to supply network, i.e. active power flow
When control switch breaks down, since ammeter itself can be with switch, the control terminal of power detection device can be to intelligent electric meter control
Device processed sends control signal, disconnects intelligent electric meter internal switch, disconnects separation and avoids to carry out further protection
There is maintenance accident.
The Power System Intelligent prevents unordered anti-power transmission device, the test side of power direction detection device and active power
Power flowcontrol switch is mounted in the shell of intelligent electric meter, test side and active power flow by power direction detection device
Control switch is mounted between switch and the leading-out terminal of intelligent electric meter, and the communication ends of power direction detection device directly pass through serial ports
It is connect with the controller of intelligent electric meter.Power direction detection device and active power flow control switch are integrated in intelligent electricity
In the shell of table, the integral structure for encapsulating it eliminates the test side of intelligent electric meter controller, power direction detection device
Communication device between active power flow control switch, avoiding Communication causes the present invention to be unable to operate normally, and mentions
High practicability of the invention.
The present invention has the beneficial effect that compared with prior art
