Description
Technical field
The utility model relates to a kind of transformer station, specifically a kind of night anti-theft early-warning transformer station.
Background technology
Transformer station is one of equipment of each community indispensability, and it carries the supply of the normal electricity of whole community, so will ensure that it normally works, work about electric power personnel generally can regularly safeguard it; Present community transformer station generally all builds the corner remoter in community in order to personal safety, although can ensure that transformer station can not on the impact of community resident so to greatest extent, but due to remoter night due to around do not have light easily make some lawless persons steal transformer station or destroy, but also can not to find in time; Current transformer station mainly adopts the mode increasing illuminating lamp and camera at night, carry out antitheft; This mode not only expends many energy, and expensive.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides the transformer station of anti-theft early-warning at a kind of night, when can have light in power transformation at night casing, sends early warning sound, thus makes surrounding resident Timeliness coverage, process.
To achieve these goals, the technical solution adopted in the utility model is: this at night anti-theft early-warning transformer station, comprise power transformation casing and photoinduction prior-warning device, photoinduction prior-warning device is arranged in power transformation casing, described photoinduction prior-warning device comprises direct supply E, switch S, slide rheostat RP1, slide rheostat RP2, photodiode DL, electrochemical capacitor C1, electric capacity C2, resistance R, light emitting diode D, base integrated chip and early warning chip when 555, the positive pole of direct supply E is electrically connected with one end of switch S, the other end of switch S and one end of slide rheostat RP2, base integrated chip when 555
port, 555 time the VCC port of base integrated chip and one end electrical connection of slide rheostat RP1, the other end of slide rheostat RP2 respectively with 555 time base integrated chip
port is connected with the negative electricity of photodiode DL, the other end of slide rheostat RP1 with 555 time base integrated chip D port be electrically connected and pass through resistance R respectively with 555 time the TH port of base integrated chip and the positive pole of electrochemical capacitor C1 be electrically connected, the negative pole of direct supply E and one end of photodiode DL, electric capacity C2,555 time the GND port of base integrated chip, the negative pole of electrochemical capacitor C1, the positive pole of light emitting diode D and early warning chip be electrically connected, the other end of electric capacity C2 with 555 time base integrated chip CO port be electrically connected, the negative pole of light emitting diode D is electrically connected with early warning chip, early warning chip with 555 time base integrated chip OUT port be electrically connected.
Further, described early warning chip is sound integrated chip KD9310.
Compared with prior art, the utility model is by photoinduction prior-warning device, complete darkness state is in power transformation at night casing, when there being light in power transformation casing, explanation has personnel to enter, and now photoinduction prior-warning device can send sound and light alarm, thus makes surrounding resident Timeliness coverage, and correspondingly process, ensure that transformer station can not stolen and damage.

Fig. 2 is circuit diagram of the present utility model.
In figure: 1, power transformation casing, 2, photoinduction prior-warning device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model comprises power transformation casing 1 and photoinduction prior-warning device 2, photoinduction prior-warning device 2 is arranged in power transformation casing 1, described photoinduction prior-warning device 2 comprise direct supply E, switch S, slide rheostat RP1, slide rheostat RP2, photodiode DL, electrochemical capacitor C1, electric capacity C2, resistance R, light emitting diode D, 555 time base integrated chip and early warning chip, the positive pole of direct supply E is electrically connected with one end of switch S, the other end of switch S and one end of slide rheostat RP2,555 time base integrated chip
port, 555 time the VCC port of base integrated chip and one end electrical connection of slide rheostat RP1, the other end of slide rheostat RP2 respectively with 555 time base integrated chip
port is connected with the negative electricity of photodiode DL, the other end of slide rheostat RP1 with 555 time base integrated chip D port be electrically connected and pass through resistance R respectively with 555 time the TH port of base integrated chip and the positive pole of electrochemical capacitor C1 be electrically connected; The negative pole of direct supply E and one end of photodiode DL, electric capacity C2,555 time the GND port of base integrated chip, the negative pole of electrochemical capacitor C1, the positive pole of light emitting diode D and early warning chip be electrically connected, the other end of electric capacity C2 with 555 time base integrated chip CO port be electrically connected, the negative pole of light emitting diode D is electrically connected with early warning chip, early warning chip with 555 time base integrated chip OUT port be electrically connected.
Further, described early warning chip is sound integrated chip KD9310.
During use, when night every day, photoinduction prior-warning device 2 is opened, owing in power transformation casing being the space of near-hermetic under closed condition, now be in dark state in power transformation casing, if when having light in power transformation casing, illustrate that power transformation cabinet door is unlocked, namely have personnel to enter; Now photoinduction prior-warning device can send sound and light alarm, thus makes surrounding resident Timeliness coverage, and correspondingly processes, ensure transformer station can not stolen and damage; The concrete course of work is: when 555, base integrated chip forms light-operated monostable circuit with photodiode DL and peripheral component thereof, when unglazed photograph or light more weak, photodiode DL internal resistance is comparatively large, base integrated chip when making 555
port be in high level input, therefore, when 555, the OUT port of base integrated chip is low level output, thus makes sound integrated chip KD9310 can not get voltage, so time do not sound.
If when having light in power transformation casing, now light strengthens suddenly, photodiode VDL internal resistance is reduced, now 555 time base integrated chip
port is in low level input, then 555 time base integrated chip OUT port be high level output, be added to the power end of sound integrated chip KD9310, thus make sound integrated chip KD9310 start and send early warning sound; Make light emitting diode D conducting simultaneously, carry out flashing; And then enhancing light intensity, even if lighting device cuts out by the personnel that now enter, this equipment also can due to light emitting diode D send light, continue to carry out early warning.
