Abstract
The invention relates to a property public electricity management device, in particular to a corridor public electricity current limiting protector. The technical scheme is as follows: the corridor public electricity current limiting protector mainly comprises a power supply input end, an output end, a current limiting resistor, a current on-off control circuit and a signal element, wherein a current on-off control element mainly comprises a photoelectric coupler, a switch controller, a controlled silicon and a triode; the output end of the photoelectric coupler is connected with the controlled silicon, and the input end of the photoelectric coupler is connected with the triode; and the output end of the switch controller controls conduction and cutoff of the triode, and the input end of the switch controller is connected with the photoelectric coupler. The corridor public electricity current limiting protector has the advantages that: by arranging the current on-off control circuit, when the load of corridor public electricity exceeds a set value, the output end can stop power supply to cause a corridor lighting lamp to stop work, and until inappropriate loads are removed, normal power supply is restored for the circuit, so the public electricity can be greatly saved, and electricity stealing and electric leakage of the public electricity are avoided.
Description
Technical field:
The present invention relates to a kind of property common electrical management devices, the public electric limiting protector of particularly a kind of corridor.
Background technology:
Along with the development of community, the precision management of each service for infrastructure unit is also more and more meticulousr, and community has problem to be solved to save the cost enhancing efficiency by relying on tapping internal latent power exactly, through the shared electric tracing of the corridor of part infrastructure management company is investigated.The power consumption of finding some corridor is very surprising, can reach the electricity of degree more than 70 in every month, few 20-30 degree electricity in addition, and normal power consumption should be spent electricity more than 10, and the electric weight that electric company appraises and decides to us is every month each corridor 13-15 degree.
Cause the excessive reason of the public electric consumption of corridor to be: it is public that (1) some resident's private connects corridor; (2) the corridor lamp bulb burns out the back resident and according to the acoustic control lamp load power bulb (general acoustic control lamp bulb is 25w) is not installed; (3) it is public that the workmen has used corridor in work progress; (4) public electric equipment such as acoustic control lamp, building door has leaky, has caused power excessive.
In order to control public electric weight, the measure that property is taked is: the corridor excessive at electricity consumption partly used the ammeter of checking card, and every month only to filling the electric weight of some.When electric weight uses up, cut off the power supply automatically, use the ammeter of checking card to save electric weight, but still brought inconvenience to the resident in the application process: 1, fill electricity with and used in a couple of days that corridor lamp has not just worked; 2, the resident can only feel about in the dark time of being left and enter corridor; 3, brought very big potential safety hazard; 4, reduced the reputation of sub-district property simultaneously.
