The utility model can realize the power supply stop of branch circuits in a plurality of unmanned rooms, on the premise that a centralized power supply on a power limiting cabinet is not cut off, and the normal and reasonable power utilization of individual branch circuit is not influenced. In this way, the utility model provides the further reinforcement of the management of saving power consumption and safe power consumption in group living places with vigorous technical measures. The utility model can be widely used for group dormitories of enterprises and institutions.
Description
The utility model relates to a kind of breaker device.
Just at present, the all kinds multichannel automatic electric limiting cabinet operating position that domestic production producer makes, all there is a common weak point, work as the maximum electric power of branch road user's power consumption if be exactly less than regulation, as daytime or night, the student goes to class or studies by oneself in scheduled time, in the room under the unmanned situation of opening lamp again on the scene, at this moment the cabinet of rationing the power supply wants these electricity consumption branch roads are cut off the power supply, just must disconnect the centrally connected power supply power supply cashier's office in a shop of rationing the power supply, doing like this and can bringing thereupon influences the normal rational utilization of electricity that other has people branch road user on the scene individually.
The object of the invention is, a kind of branch road breaker device is provided, it can accomplish not disconnect the centrally connected power supply power supply cashier's office in a shop of rationing the power supply, do not influence under the normal rational utilization of electricity prerequisite of indivedual branch roads, just can stop power supply to some unmanned branch roads in room, thereby can avoid the consumption in vain of electric energy, reach energy-conservation purpose.
The technical scheme that the utility model is taked is, a kind of branch road breaker device of pressing generator (5), electric power sampling detector (7) and photoelectricity coupling unit (6) to connect to form by main DC voltage generator (4), relay (3), amplifier (2), auxiliary direct current, its special character is, this device also comprises and forces operating part (1).
The further special character of the utility model also is, forces the clamping diode D of operating part (1)
7Positive pole be connected to electrochemical capacitor C
6Negative pole, be connected to simultaneously transistor T again
1, T
2On the convergence point of collector electrode and relay J one end, D
7Negative pole be connected on the terminal Z, be connected on the cabinet N line of rationing the power supply by master switch K again after all terminal Z tandems.
Effect of the present utility model is, because the utility model is on the basis of conventional branch road breaker device, has increased a kind of branch road breaker device that forces operating part to constitute.It can accomplish not disconnect the centrally connected power supply power supply cashier's office in a shop of rationing the power supply, do not influence under the normal rational utilization of electricity prerequisite of indivedual branch roads, stop the power supply on some on-the-spot unmanned branch roads, thereby strong technological means is provided for the further electrical energy saving in reinforcement collective livelihood place and the management of safety utilization of electric power.As if it is unmanned but still opening the situation of lamp that the collective livelihood place of dormitory and so on is easy to exist in daytime or the night room.If there are 100 rooms in a dormitory, wherein have 20% room student do not go night to study by oneself in scheduled time and daytime also dodge a lesson, and be that 80W adds up by the electric power in each room, the dormitory in 100 rooms so, the electric energy of saving in a year is: 80W * 80 (room number) * (nobody room on 2 hours+daytime of time, room in night nobody 4 hours time) * 365 days=14016 degree.Description of drawings:
Accompanying drawing 1 is a kind of branch road breaker device theory diagram.
During normal power supply, exchange the input general supply and deliver to branch road electricity consumption output L ' through normal make contact of relay (3) and electric power sampling detector (7).
When certain branch road electric power surpassed regulation, electric power sampling detector (7) provided one to transfinite and use electrical input signal just for amplifier (2), made the latter export a low level and removed the power supply that drives relay (3) adhesive, cut off this branch road.
If when having n bar branch road electric power to surpass setting now, need only the momentary connection public master switch K of all branch roads once, be generally turn-on time more than 0.2 second.At this moment, force the operating part (1) just can be with A point pincers to ground level and force n relay (3) adhesive, disconnect normal make contact.Meanwhile, auxiliary direct current is pressed generator (5) to constitute the loop by branch road with electric loading and is obtained AC-input voltage, generation auxiliary direct current pressure is passed through photoelectricity coupling unit (6) again and the electricity consumption transducing signal that transfinites is provided for amplifier (2), make amplifier (2) output terminals A be in ground level, relay (3) forever keeps adhesive, thereby branch road electricity consumption output is stopped power supply, so compartment lamp does not work.But for people room on the scene is arranged, as long as the branch road load switch is disconnected, just can make auxiliary direct current press generator (5) to lose the supply of alternating voltage, so auxiliary direct current is pressed also and is disappeared simultaneously thereupon, thereby make photoelectricity coupling unit (6) lose drive signal, cause transfiniting of amplifier (2) input also just and then to disappear naturally with the signal of telecommunication.So, amplifier (2) output is returned on the high level of original main direct current supply voltage, relay (3) is resetted again.At this moment, exchange the input general supply and restore electricity for again this branch road again through relay (3) and electric power sampling detector (7), if this branch road load switch is connected, just can obtain supply regular power again, promptly the lamp in the room is lighted.
Accompanying drawing 2 is shape assumption diagrams of a kind of branch road breaker device.Among the figure, (8) are branch road power supply switch installing hole, and (9) are the automatic power failure lamp D of branch road
4Installing hole, (10) be branch road power supply fuse box installing hole, (11) on move stop self-tapping screw installing hole, (12) be plastic front board, (13), (15) use screw hole for branch road breaker device printed circuit board (PCB) and plastic front board (12) install and fix, (14) are branch road breaker device printed circuit board (PCB).
Accompanying drawing 3 is multichannel automatic electric limiting cabinet shape assumption diagrams.Among the figure, (16) for partly keeping in repair, the cabinet major loop uses button fly front, (17) be branch road breaker device installation site, (18), (19) be supporting slide track, (20) be handle, (21) be voltmeter, (22) release the button for the cabinet general supply, (23) are the cabinet total power light, and (24) are cabinet general supply X button, (25) be floor public place normal power supply button, (26) be floor public place normal power supply indicator light, (27) are that the power supply button is pressed in floor public place half, and (28) are that the power supply indicator light is pressed in floor public place half, (29) be the floor public place button of stopping power supply, (30) are branch road outage master switch K.
