Abstract
The utility model relates to a burglar alarm of a power distributing cabinet in the power supply control field, and is provided with the technical proposal as follows: a main power supply circuit is composed of a transformer B, a rectifier DZ, a capacitance C and a voltage regulator diode DW; an alarm raising circuit is composed of an alarm integrated circuit IC, a resistor R, a triode T and a loudspeaker; a starting circuit is composed of buttons AN which are arranged in the doors of the power distributing cabinet, a control box, etc.; and X and Y are connected with the main power supply circuit. The burglar alarm with simple structure and convenient usage can be arranged on the needed power distributing cabinet or the control box, raise alarms along with the door opening of the power distributing cabinet or the control box, and play the roles of safety in production and alarm providing.
Description
Technical field
The utility model relates to a kind of power distribution cabinet burglar alarm in power supply control field.
Background technology
Each manufacturing enterprise and power supply management all use a large amount of power distribution cabinets, control box etc. at present, to lay all kinds of gauge tap or other opertaing devices.Existing power distribution cabinet, control box etc. do not have alarming device substantially, when power distribution cabinet, control box need inspection, maintenance, owing to lack necessary cautionary measure, can cause the electric shock casualty accident because of work carelessness or ignorant once in a while.In addition owing to many power distribution cabinet devices use in the open air, the offender of some theft electric power facilities often at first will open power distribution cabinet, and theft is implemented in the back of cutting off the electricity supply, if lack necessary warning device, the nurse personnel are difficult to find, thereby cause power failure and property loss.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of power distribution cabinet burglar alarm with automatic caution and burglar alarm effect is provided.
Its technical scheme is: be made up of button AN that is fixed on cabinet door inboard and the alarm circuit that is connected behind the button AN, described alarm circuit is to connect to form the circuit supply circuit by transformer B, rectifier bridge DZ, capacitor C and voltage stabilizing diode DW, is connected with phonetic warning integrated circuit (IC), resistance R, triode T and loudspeaker L composition phonetic warning and sends circuit behind the circuit supply circuit.On loudspeaker L, also be parallel with the flash of light warning lamp.
The utlity model has simple in structure, install additional conveniently, be installed on the power distribution cabinet that needs, the control box, can play and send the caution audio alert with the unlatching of doors such as power distribution cabinet, control box, play the effect of keeping the safety in production and warning being provided.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.X, Y connect power supply among the figure; Knob AN is installed in the door inboard of power distribution cabinet, control box etc., and AN disconnected when door was closed at ordinary times, connected when door is opened.
Embodiment
Be further described with regard to its principle of work below in conjunction with accompanying drawing: connect the input end of rectifier bridge DZ by transformer B, the be connected in parallel output terminal of rectifier bridge DZ of capacitor C and voltage stabilizing diode DW is formed main power circuit; Form the oscillatory circuit of IC by phonetic warning integrated circuit (IC) parallel resistance R, IC connects triode T and loudspeaker L and forms the caution voice and send circuit; X, Y connect in the electric power main circuit; Knob AN is installed in the door inboard of power distribution cabinet, control box etc., and AN disconnected when door was closed at ordinary times, connected when door is opened.On loudspeaker L, also be parallel with the flash of light warning lamp, report to the police and carry out flashing light alarm simultaneously.
AN disconnected when door was closed at ordinary times, forming main power circuit by transformer B, rectifier bridge DZ, capacitor C and voltage stabilizing diode DW does not work, so the caution voice of being made up of phonetic warning integrated circuit (IC), resistance R, triode T and loudspeaker L send the circuit non-transformer and sounding not.AN connects when door is opened, form main power circuit work by transformer B, rectifier bridge DZ, capacitor C and voltage stabilizing diode DW, at this moment, the caution voice of being made up of phonetic warning integrated circuit (IC), resistance R, triode T and loudspeaker L send circuit and obtain working power and send caution.
Claims (2)
1, a kind of power distribution cabinet burglar alarm, it is characterized in that: form by button AN that is fixed on cabinet door inboard and the alarm circuit that is connected behind the button AN, described alarm circuit is to connect to form the circuit supply circuit by transformer B, rectifier bridge DZ, capacitor C and voltage stabilizing diode DW, is connected with phonetic warning integrated circuit (IC), resistance R, triode T and loudspeaker L composition phonetic warning and sends circuit behind the circuit supply circuit.
2, power distribution cabinet burglar alarm according to claim 1 is characterized in that: also be parallel with the flash of light warning lamp on loudspeaker L.
