Abstract
The utility model provides a distribution facility anti-theft alarm which includes a phase reverser, a modulating oscillator, an alarm module and an electrical power source module. The electrical power source of the distribution facility connects with the phase reverser, an output end of the phase reverser connects with the modulating oscillator, the modulating oscillator connects with the alarm module, the electrical power source provides electrical power source for the phase reverser and the modulating oscillator. The provides a distribution facility anti-theft alarm aims to the domestic installation with single phase AC 220V voltage of urban resident, theft the distribution facility must passes a power-down course which must cause electrical power terminal interrupt of the urban resident, so the electrical power terminal of the urban resident is detected and the reverse phase signal is took for touching the alarm working to remind asleep resident and realize prophase omen and pre-alarm to the distribution facility anti-theft. The distribution facility anti-theft alarm has advantages of simple structure, easy to realize and widely used in various distribution facility anti-theft alarm.
Description
Technical field
The utility model is a kind of antitheft on-line measuring device of distribution facility that is used for, and this device can send acousto-optic soon and remind when disconnection fault appears in the residential customers receiving end, be a kind of distribution facility burglar alarm.
Background technology
Distribution facility is in service, can run into unprincipled fellow's theft, as common theft substation transformer, low pressure service conductor or the like.The thief often utilizes crime in the late into the night, and at this moment everybody is difficult to find at resting state, more can't drive and catch.If there is a kind of method can detect the sign in early stage of theft distribution facility; and remind the common people in sleeping soundly, and just can accomplish to unite the arrest of driveing or report to the police, just can protect distribution facility not stolen; guarantee the normal electricity consumption of client, the utility model is researched and developed this.
Summary of the invention
Problem to be solved in the utility model is: at the distribution facility theft situation of present existence, need a kind of warning device of civilian distribution facility, reduce the stolen of distribution facility.
The technical solution of the utility model is: the distribution facility burglar alarm, comprise phase inverter, modulating oscillator, alarm module and power module, the power supply of distribution facility connects phase inverter, the output terminal of phase inverter connects modulating oscillator, modulating oscillator connects alarm module, and power module provides power supply to phase inverter and modulating oscillator.
The utility model alarm module comprises hummer and light emitting diode.The power supply of distribution facility connects power module, the built-in trickle automatic charger of power module.Be the convenience and the safety of guarantee use, according to the civil electric appliance standard phase inverter, modulating oscillator, alarm module and power module concentrated to be encapsulated in all insulation closed shell that power module is provided with external plug, described external plug and shell are whole.
Life of urban resident has possessed the domestic installation of 220 volts of single-phase ACs.The theft distribution facility must be through the process of an outage, certainly will cause residential customers electric terminal power interruption like this, by detecting residential customers electric terminal power source voltage, get its inversion signal and trigger alarm work, just can remind the common people in sleeping soundly, realize that the antitheft sign in early stage of distribution facility detects and early warning.The utility model is simple in structure, is easy to realize, can be widely used in the burglar alarm of all kinds of distribution facilities.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model circuit diagram.
Embodiment
As Fig. 1, be structural representation of the present utility model, comprise phase inverter 1, modulating oscillator 2, alarm module 3 and power module 4, the power supply of distribution facility connects phase inverter 1 and power module 4 respectively, the output terminal of phase inverter 1 connects modulating oscillator 2, modulating oscillator 2 connects alarm module 3, and power module 4 provides power supply to phase inverter 1 and modulating oscillator 2.
Fig. 2 is a kind of concrete enforcement circuit of the present utility model, when voltage is normal, distribution facility only can charge by trickle automatic charger 41, when the voltage of distribution facility is lower than the alarm preset threshold, then phase inverter 1 triggers modulating oscillator 2, makes alarm module 3 work.
In order to guarantee operate as normal of the present utility model, at technological layer to strengthen:
1), alerting pattern: the flashing light of blowing a whistle is reminded but power-off time is had a rest, up to restoring electricity or manually suspending and remind;
2), warning volume :≤60 decibels;
3), high voltage withstanding design: but the circuit design long-term work of specialty is in 280V, even line voltage exceeds standard also not fragile after midnight;
4), super wide monitoring voltage: AC110V～265V, in this scope, can guarantee every function of alarm and can false alarm, the scope of application is wider;
5), automatically charging: built-in trickle automatic charger, both can use common batteries, can use rechargeable battery again;
6), change battery: the energy storage section of power module design drawer type battery cover on the shell, switch is convenient, can change battery at an easy rate.
Claims (5)
1, distribution facility burglar alarm, it is characterized in that comprising phase inverter, modulating oscillator, alarm module and power module, the power supply of distribution facility connects phase inverter, the output terminal of phase inverter connects modulating oscillator, modulating oscillator connects alarm module, and power module provides power supply to phase inverter and modulating oscillator.
2, distribution facility burglar alarm according to claim 1 is characterized in that alarm module comprises hummer and light emitting diode.
