Description
Technical field
This utility model relates to a kind of pre-power purchase high pressure measurement trip(ping) circuit, particularly a kind of based on nonlinear wind vibration
Controller to pre-power purchase arrearage trip(ping) circuit implementing monitoring.
Background technology
There is following defect in pre-power purchase high pressure measurement trip(ping) circuit in the market:
1, loop goes offline
In high-voltage metering cubicle, trip signal is to be sent by the intelligent electric meter being loaded in high-voltage metering cubicle, and trip switch
Being not in same cabinet with intelligent electric meter, its trip signal need to through the binding post of high-voltage metering cubicle, then lead to be correlated with
Need outgoing line cabinet or the binding post of incoming line cabinet of tripping operation, be then connected to the trip(ping) circuit of trip switch through this binding post,
In the running of switch cubicle, the situation that this trip signal transmission loop goes offline, therefore, owing of intelligent electric meter often occur
Though expense signal sends, but can not trip successfully.
2, artificially break
The power mode of pre-power purchase, is widely popularized by power marketing department, how to guarantee arrearage not electricity consumption, and electricity consumption is the most pre-
Purchase, be the thing paid close attention to the most of power marketing department, when using the special trip(ping) circuit of artificial destruction such as electric consumer, when controlling machine room
After arrearage signal sends, tripping operation can not be implemented, or causes arrearage to run, or needs power marketing personnel to run a timing according to arrearage
Back-end data analysis after between, more manually have a power failure to electricity consumption field conduct, increase labor intensity.
3, difficulty is patrolled and examined
In the trip(ping) circuit of high-voltage switch gear, contact, rectifier bridge, current/voltage coil etc. are the most all gone here and there, under normal circumstances
It is all charging operation state, when power supply department is normally patrolled and examined, whether is in normal condition by detection trip(ping) circuits such as circuit testers,
Can not be tested by scene tripping operation success or not, otherwise cause power failure accident.
Utility model content
Technical problem to be solved in the utility model is, not enough for prior art, it is provided that one can be to using forward purchasing
The trip(ping) circuit of the high-voltage metering cubicle of electricity realizes monitoring in real time, it is ensured that after arrearage signal sends, trip switch tripping operation successfully control
Device processed.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of to pre-power purchase arrearage tripping operation
The controller of loop implementing monitoring, it includes LCD MODULE, micro-control unit, GPRS communication module, Control mould
Block, VA gather memory module, DC power supplier, wherein, LCD MODULE, GPRS communication module, relay control module,
VA gathers memory module, DC power supplier is connected with micro-control unit respectively, and the first control of relay control module continues
Electrical equipment concatenates the front end into trip(ping) circuit, for isolating the action control power supply of trip(ping) circuit;DC power supplier is through relay
The rear end of trip(ping) circuit received by second control relay of control module, for loading one group in trip(ping) circuit less than 24V's
DC voltage;The rear end of this trip(ping) circuit gathers memory module through VA and is connected with micro-control unit.
This VA gathers filtering partial pressure unit, impedance matching unit and the A/D converting unit that memory module includes being linked in sequence.
This utility model is by loading one group of magnitude of voltage less than 24V in trip(ping) circuit, and records different magnitude of voltage and exist
The current value formed in trip(ping) circuit, and in view of the resistance of the element such as diode and electric capacity present in trip(ping) circuit with temperature
Variation characteristic (voltage is different, and temperature rise is also different), and with a coefficient, the current value recorded is corrected, thus formed non-linear
C-V characteristic standard curve, recycling said method in the case of normal electricity consumption, monitoring trip(ping) circuit in current value, if electric
Flow valuve deviates nonlinear wind vibration standard curve really, then notify that management personnel carry out relevant treatment, it is thus possible to make administrative man
Member can find fault in time and get rid of, and trip(ping) circuit is properly functioning.Further, since the action control power supply of trip(ping) circuit is
Being isolated in advance by this utility model, the magnitude of voltage of DC power supplier is far below the working value of trip(ping) circuit, and therefore, this practicality is new
Type, when patrolling and examining trip(ping) circuit, does not results in line switch or the misoperation of forward purchasing electric switch.
