Description

The intelligent power monitor

Technical field

The utility model relates to a kind of safe and intelligent electricity consumption monitor, the safe and intelligent electricity consumption monitor of especially a kind of monitoring and guarantee Electrical Safety.

Background technology

Family, trade company use in the alternating voltage of civil power 220v at present, monitoring to electric leakage, overload has ripe technology, but operate time is longer, and the index precision is not high, generally all adopt better simply apportion component electronic circuit, can not solve in the electricity consumption loop electric arc that breaks down; The unexpected overtension of civil power causes that electric equipment damages; Electricity consumption loop and electric equipment products are aging, insulating properties descends, thereby the burst partial short-circuit occurs, cause the situation of fire, and existing monitoring technology can't be reported to the police and the fast shut-off power supply especially, prevents the generation of electric accident.

Summary of the invention

The problem that exists for solving prior art, the utility model provides a kind of intelligent power monitor, and its monitor set and ensureing in one is avoided with the multiple unsafe factor in electric process.

The utility model is achieved through the following technical solutions: the utility model comprises input line connectivity port, output line connectivity port, also comprises the single-chip microcomputer that can provide according to the numerical value of voltage, leakage current, fault electric arc, power load unlike signal and the early warning that is connected with this single-chip microcomputer test key, report to the police test key, reset key and signal indicator.

Further, also be connected with voltage sensor, voltage waveform amplifier and lock-out pulse generator between described input line connectivity port and single-chip microcomputer.

Further, also be connected with current sensor, active filter, current waveform amplifier and rectifier between described input line connectivity port and single-chip microcomputer.

Further, also be connected with leakage current transducer, active filter, current waveform amplifier and rectifier between described input line connectivity port and single-chip microcomputer.

Further, described signal indicator is comprised of run signal lamp, overvoltage signal lamp, electric leakage signal lamp, arc signal lamp and overload light.

Further, described safe and intelligent electricity consumption monitor also comprises a communication interface, can and control with central controller networking monitoring.

The beneficial effects of the utility model are: the utility model can be safer to family, trade company's electricity consumption, and can be effectively with unsafe factor in electricity consumption, different faults set and the one of for example overvoltage, electric leakage, fault electric arc, overload are carried out early warning and warning, in time cut off the electricity supply, and each warning is recorded and shown, so that electric accident cause inquiry.

Fig. 3 is functional-block diagram of the present utility model.

In the drawings: 4-early warning test key; 5-reports to the police and tests key; The 6-reset key; The 7-signal indicator; The 8-communication interface.

Embodiment

As shown in Figure 1-Figure 3, the utility model comprises input line connectivity port, output line connectivity port, also comprises the single-chip microcomputer that can provide according to the numerical value of voltage, leakage current, fault electric arc, power load unlike signal and the early warning that is connected with this single-chip microcomputer test key 4, report to the police test key 5, reset key 6 and signal indicator 7.

Further, described signal indicator 7 is comprised of run signal lamp, overvoltage signal lamp, electric leakage signal lamp, arc signal lamp and overload light.

Further, the utility model also comprises a communication interface 8, can and control with central controller networking monitoring.

Major function of the present utility model is:

First: monitoring mains-supplied voltage,, when monitoring supply power voltage more than 260 volts the time, send the overvoltage early warning signal, the overvoltage indicator light dodges, and sends early warning sound.When supply power voltage surpasses 270 volts, send the over voltage alarm signal, the overvoltage indicator light is bright, sends chimes of doom, and automatic cut-off power prevents the electric equipment products damage.

Second: the electric leakage situation of monitoring in electric process, when the user uses electric heater that electric leakage is arranged or during due to power utilization environment is moist, wire insulation decline occurs electric leakage situation, the utility model monitors leakage current less than 10 MAHs, send early warning signal, the electric leakage indicator light dodges, and sends early warning sound., greater than 10 MAHs, send alarm signal when leakage current, the electric leakage indicator light is bright, sends chimes of doom, and automatically cuts off power supply, prevents dead and other accidents of person electric shock.

The 3rd: the fault electric arc (being the circuit arcing) of monitoring electricity consumption loop and electrical equipment, when electricity consumption loop or electric equipment products inside have loose contact or insulation crust insulating properties descend and electric arc occurs.When fault electric arc is no more than the national regulation value, send early warning signal, the electric arc indicator light dodges, and sends early warning sound.When fault electric arc surpasses the national regulation value, send alarm signal, the electric arc indicator light is bright, sends chimes of doom.Automatically cut off power supply.Automatically switch on power after 30 seconds, if monitor, still have fault electric arc, again start automatic cut-off power, this time no longer restore electricity after dump, can effectively prevent the generation of the electrical fire accident that fault electric arc causes.

The 4th: monitoring power load situation, when monitoring power load and reach the rated load value, send early warning signal, overload light dodges, and sends early warning sound; When power load surpasses rated load value 15% or due to electricity consumption aging circuit and electrical equipment internal soundness problem, cause that partial short-circuit causes the zooming situation of power load, send alarm signal, overload light is bright, sends chimes of doom; Automatic cut-off power, to prevent that the electricity consumption loop from damaging and special generating gas fire incident occurs.

The the 5th: can pass through communication interface 8, monitoring information is controlled and record to central control room by bus or the teletransmission of carrier communication mode.

Should be noted in the discussion above that above monitoring and control threshold values and all can change as requested by software.

Should be noted that finally; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection range; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement, all do not break away from essence and the scope of technical solutions of the utility model.
