The utility model has the characteristics of simple structure, convenient to use, safe and reliable etc, be suitable for power line and transformer theftproof and use.
Description
The utility model belongs to the AC dump warning device, especially a kind of power circuit, transformer power failure alarm device of being applicable to.
For a long time, the rural area low-tension transformer is owing to lack effective safe precaution measure, often stolen and tear open by the offender, cause large tracts of land to have a power failure for a long time, economic loss is huge, having had a strong impact on local resident's productive life, is one of rural power service safety three big hidden danger (robber tears the tower material open, the robber cuts electric wire, steals and tear transformer open).In recent years, this type of incidence of criminal offenses is also on the rise.Patent gazette the 7th volume discloses a kind of rheostat power line anti-theft alarm device No. 7, by equal energy burglar alarm under impedance conversion sensing circuit, comparator circuit and warning circuit, power failure and the electric power thus supplied, to not interference of electrical appliance on every side, and be provided with phase failure power failure demonstration.Its complex structure, poor reliability only is applicable to three-phase alternating current, is not suitable for rural power circuit and transformer anti-theft.
The purpose of this utility model provides a kind of simple in structure, good reliability, has the multifunction power transformer and the circuit power-off alarm of illumination, warning function concurrently.
The purpose of this utility model is achieved in that a kind of multifunction power transformer and circuit power-off alarm, it comprises housing, the cut-offing alarming circuit that is provided with in the housing, cut-offing alarming circuit comprises the socket that is connected with power supply, transformer B, pilot lamp with transformers connected in parallel, rectification circuit, filtering circuit, relay J is in parallel with rectification circuit, lighting circuit is connected with the relay J normally closed contact, the accumulator in parallel with lighting circuit, the charging control circuit that is connected with rectification circuit is set, it is composed in series by three terminal regulator and diode, and diode is connected with the contact of relay J; The news in parallel with illuminating lamp are rung circuit, and news are rung circuit and comprised music-integrating block, the triode that links to each other with music-integrating block, loudspeaker, resistance R
5In parallel with music-integrating block.
Because the utility model charging control circuit, lighting circuit, news are rung warning circuit, have characteristics such as simple in structure, esy to use, safe and reliable, therefore can be installed in the user family, and have the light demonstration, advantages such as power-cut emergency lighting are suitable for power circuit and transformer anti-theft and use.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is circuit theory diagrams of the present utility model.
The circuit theory explanation:
Multifunction power transformer and circuit power-off alarm, it comprises the cut-offing alarming circuit that is provided with in the housing, housing, cut-offing alarming circuit comprise the socket that is connected with power supply, transformer B, and the pilot lamp LED1 of transformers connected in parallel, by diode D
1, D
2, D
3, D
4The rectification circuit of forming, by the filtering circuit that capacitor C is formed, relay J is in parallel with rectification circuit, lighting circuit is connected with the relay J normally closed contact, the accumulator in parallel with lighting circuit is provided with the charging control circuit that is connected with rectification circuit, and it is by three terminal regulator 7808 and diode D
7, D
8Be composed in series diode D
8Be connected with the contact of relay J; The news in parallel with illuminating lamp are rung circuit, and news are rung circuit and comprised music-integrating block, the triode, the loudspeaker that link to each other with music-integrating block M, resistance R
5In parallel with music-integrating block.
LED1 (red) is a charge indicator, LED2 (green) is for opening luminous lamp switch or opening news and ring circuit indicators, BG is common NPN type triode, as 9013 etc., K3 is small-sized button throw switch, D7, D8 are the ordinary silicon diode, and as 1001 etc., accumulator E should select quality 6V3AH maintenance-free battery preferably for use.Constant-voltage charge, charging voltage is about 6.4V.Principle of work is that the alarm plug is plugged AC power, opens K3, when interchange is arranged, and rectification circuit work, LED1 is luminous, and the adhesive of relay J normally open contact charges a battery, and by K switch 3, resistance R
5, R
2With illuminating lamp L1, resistance R
3, with illuminating lamp L2 make pilot lamp LED2 luminous, alarm enters the state of alert; During AC dump, relay J discharges, its normally closed interlock closure, and accumulator rings circuit supply for news by J normally closed interlock, K switch 3, sends police whistle sound.
Resistance R
5For pilot lamp LED2 provides path and protects music-integrating block.
In a single day alarm comes into operation, and should often detect.Can adopt and dial attaching plug down, or (most " it is precious to have a power failure " all are equipped with a normally closed button to press testing button A, principle is to disconnect AC power), listen and whether send chimes of doom, open illuminating lamp, see whether light is bright, check that whether the accumulator electric energy is sufficient, guarantees that alarm often is in good working order.
