Abstract
Provided is a voice warning device indicating keeping off a transformer. The voice warning device comprises a microwave inductive switch, a voltage-stabilized power supply, a voice recording and playing module, an amplifying circuit, and a loudspeaker. The output end of the microwave inductive switch is successively connected the voltage-stabilized power supply, the voice recording and playing module, the amplifying circuit, and the loudspeaker in series. The input end of the microwave inductive switch is connected with an AC power supply from 220V to 380V. Compared with a product in the prior art, the voice warning device has advantages of reasonable design, simple structure, easy production, and easy use. When a person enters a power construction area by mistake, the warning device on a transformer is capable of reminding a passerby such as a child to be far from the electric device installing area through the warning loudspeaker. Therefore, the generation of dangers is effectively prevented.
Description
Technical field
The utility model relates to a kind of power transformer alarming device, is specifically related to a kind of transformer and forbids near the phonic warning device.
Background technology
At present, power department is equipped with guard rail around transformer, is used for preventing that children or other staff are close, in order to avoid cause Danger Electric shock risk.Guard rail of the prior art all is only to hang with the simple corral of railing or at fence to paste the literal warning sign, often do not have tangible warning function, such as children or people that some are not read, mistake is swarmed into fence easily, cause human casualty accident, bring bigger potential safety hazard to executing safety utilization of electric power.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of transformer to forbid near the phonic warning device.
Its technical scheme is: comprise microwave inductive switch, stabilized voltage supply, voice recording-reproducing assembly, amplifying circuit and loudspeaker.Be connected with loudspeaker behind the output terminal of described microwave inductive switch stabilized voltage supply in sequential series, voice recording-reproducing assembly and the amplifying circuit, the input end of microwave inductive switch connects 220-380V AC power.
Wherein, described microwave inductive switch is the radar human induction switch.Described stabilized voltage supply is the AC/DC change-over circuit, and its input voltage is for exchanging 220-380V, and output voltage is direct current 12-15V.
The utility model compared with prior art, have reasonable in design, simple in structure, be easy to make, advantage such as easy to use, when people's mistake is swarmed into the power construction zone, can effectively avoid dangerous generation by passerbys such as caution loudspeaker prompting children away from the power equipment installation region at the warning device that transformer arranges.
Description of drawings
Fig. 1 is the circuit block diagram of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of transformer is forbidden to comprise microwave inductive switch 1, stabilized voltage supply 2, voice recording-reproducing assembly 3, amplifying circuit 4 and loudspeaker 5 near the phonic warning device.The output terminal of described microwave inductive switch 1 stabilized voltage supply 2 in sequential series, voice recording-reproducing assembly 3 and amplifying circuit 4 backs are connected with loudspeaker 5, and the input end of microwave inductive switch 1 connects 220-380V AC power 6.Wherein, described microwave inductive switch 1 is the radar human induction switch, and its model can be selected M5-08A for use.Described stabilized voltage supply 2 is the AC/DC change-over circuit, and its input voltage is for exchanging 220-380V, and output voltage is direct current 12-15V.
During use, this device is installed in the transformer fence, and the connection power supply gets final product.As passerby near or when entering fence, the output terminal of microwave inductive switch 1 namely can out-put supply, this power supply converts direct current to by stabilized voltage supply 2, electric energy is provided for voice recording-reproducing assembly 3 and amplifying circuit 4, to record signal in the voice recording-reproducing assembly 3 of alarm voice in advance after amplifying circuit 4 amplifies, driving loudspeaker warning passerby " high pressure area, danger! Please withdraw rapidly ".
