Utility model content
Based on above deficiency, the technical problems to be solved in the utility model is to provide a kind of electric safety in dormitory system, and it can realize electric safety in dormitory, and can promote electrical energy saving.
For solving above technical problem, the utility model have employed following technical scheme:
A kind of electric safety in dormitory system, comprise 220V input power, transformer, leakage switch, bridge type insurance pipe and pre-paying kilowatt-hour meter, described 220V input power, pre-paying kilowatt-hour meter, leakage switch, transformer, bridge type insurance pipe and 36V lead-out terminal are sequentially connected in series, and described pre-paying kilowatt-hour meter comprises for the electric energy metering module of electric energy metrical and measures for reading the electricity that prestores and deducting electric energy metering module the data processing module that the electric energy drawn obtains dump energy.
Also comprise air switch, described leakage switch, air switch and 220V lead-out terminal are sequentially connected in series.
Also comprise display module, for showing dump energy.
Also comprise alarm module, for reporting to the police when the electricity that prestores remains 5%.
Adopt above technical scheme, the beneficial effect acquired by the utility model is:
1,220V input power is drawn 220V lead-out terminal and 36V lead-out terminal respectively, meet the needs of different electrical equipment, can electric energy be saved, electric wire and electrical heating amount can be reduced again, prevent dormitory power excess load;
2, use leakage switch and bridge type insurance pipe series connection can the security performance of intensifier circuit;
3, pre-paying kilowatt-hour meter is used, adopt the mode of pre-payment, monthly give the electric amount that civilian worker is certain, use exceedes amount and just needs to supplement magnetic card with money, supplement with money and pre-paying kilowatt-hour meter device could be used to carry out plug-in card power taking, there is crucial effect for the electricity consumption transparency of workman and electrical energy saving, effectively can ensure safety and stability and the low consumption of accommodation electricity usage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technology of the present utility model is described in further detail:
Fig. 1 is the circuit diagram of the utility model electric safety in dormitory system;
Fig. 2 is the structure chart of the utility model pre-paying kilowatt-hour meter.
Embodiment
A kind of electric safety in dormitory system, comprise 220V input power 1, transformer 2, leakage switch 3, air switch 4, bridge type insurance pipe 5 and pre-paying kilowatt-hour meter 6,220V input power 1, pre-paying kilowatt-hour meter 6, leakage switch 3, transformer 2, bridge type insurance pipe 5 and 36V lead-out terminal 7 are sequentially connected in series, and described pre-paying kilowatt-hour meter 6 comprises for the electric energy metering module 61 of electric energy metrical and measures for reading the electricity that prestores and deducting electric energy metering module the data processing module 62 that the electric energy drawn obtains dump energy.The output of bridge type insurance pipe 5 control 36V safe voltage, for the electric fan of USB charging socket, 50W power, the LED illumination lamp of 9W power, prevents that equipment heating amount is too high to go wrong.Pre-paying kilowatt-hour meter, adopt the mode of pre-payment, monthly give the electric amount that civilian worker is certain, use exceedes amount and just needs to supplement magnetic card with money, supplement with money and pre-paying kilowatt-hour meter device could be used to carry out plug-in card power taking, there is crucial effect for the electricity consumption transparency of workman and electrical energy saving, effectively can ensure safety and stability and the low consumption of accommodation electricity usage.
Native system also comprises air switch 4; leakage switch 3, air switch 4 and 220V lead-out terminal 8 are connected successively; the high-power output of the direct control 220V of air switch 4; as air-conditioning; leakage switch is for preventing the generation of electric leakage accident; air switch is used for overload protection, and leakage switch and air switch are combined can the security performance of intensifier circuit.
Pre-paying kilowatt-hour meter comprises electric energy metering module 61, data processing module 62, display module 63, alarm module 64, electric energy metering module 61 adopts large-scale application-specific integrated circuit, electric current and voltage amount is converted with active power to directly proportional pulse, realize electric energy metrical; Data processing module 62 is is also read and write the electricity that prestores in magnetic card and preserves, magnetic card can a certain amount of magnetic of preliminary filling, the number of degrees of the corresponding electricity of magnetic volume, data processing module reads the electricity that prestores in magnetic card, measure according to electric energy metering module the electricity that the umber of pulse obtained calculates consumption, and obtain dump energy by the electricity that the electricity removal that prestores consumes.Data processing module 62 is for carrying out electric energy meter degree according to the umber of pulse in the unit interval, such as, in a period of time T 1, the pulse stored count value that electric energy metering module is converted to is 32, data processing module carries out electric energy meter degree according to umber of pulse, and the electric energy value accumulative total obtained is 0.01kWh; In a period of time T 2, the pulse stored count value that electric energy metering module is converted to is 320, and data processing module carries out electric energy meter degree according to umber of pulse, and the electric energy value accumulative total obtained is 0.1kWh.Namely instrument constant meets such relation: K=Δ i/ Δ k, and wherein K is instrument constant, and the numerical value change amount of Δ i indicating impulse accumulated counts value, Δ k represents the numerical value change amount of electric flux accumulated counts value.Data processing module 62 can also control the number of degrees of display module to electricity remaining in magnetic card and show, and when remaining electricity is less than 5%, controls alarm module and reports to the police, prevent because electricity in magnetic card uses up unexpected power-off.
Mode so is adopted to carry out power taking, can effectively limit civilian worker and arbitrarily waste electricity consumption, monthly give the electric amount that civilian worker is certain, use exceedes amount and supplements electricity card with money with regard to needs, supplement with money and pre-paying kilowatt-hour meter 6 could be used to carry out plug-in card power taking, there is crucial effect for the electricity consumption transparency of workman and electrical energy saving, effectively can ensure safety and stability and the low consumption of accommodation electricity usage.Meanwhile, in whole system, be equipped with the authority card of keeper, can under emergency case, use management person's authority card is dormitory power transmission, prevents the power-off of emergency case, ensures the convenient of electricity consumption.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
