Abstract
The utility model discloses a self-locking power-off power-saving switch, which is designed aiming at the phenomenon of waste that a lamp is still on when no one in the place which the lamp is installed. The utility model is characterized in that a special self-locking circuit which needs only a phase line without a zero line is adopted. The utility model has the advantages of small size, convenient installation and use.
Description
The utility model relates to a kind of outage power down switch that only needs phase line.
At present, the switch of the unit that ration the power supply the daytimes such as dormitory of each universities and colleges and enterprises and institutions is normally closed, switching lamp is by the unified control of administrative staff, no matter whether therefore formed needs illumination, lamp is just bright as long as administrative staff power, be " altar lamp " phenomenon that ubiquity, cause the huge waste of electric power.And for a long time, this problem never is well solved.
The purpose of this utility model is to provide a kind of power down switch that is used to solve dormitory " altar lamp " problem, realizes the purpose of saves energy, has stopped the phenomenon of " people is not kept burning day and night at lamp ".
Principal character of the present utility model is: self-locking outage power down switch is made up of switch sections and relay control section, and only needs phase line, does not need zero line; Its switch sections is to be composed in parallel by the make contact (2) of push-button switch (1) with relay; Its relay control section is that DC voltage relay winding (6) is in parallel with electric capacity (5), again with the two ends that are connected across resistance (3) after diode (4) is connected.
Advantage of the present utility model is:
1, energy-saving effect is remarkable: be example with the Harbin Institute of Technology, average every day can economize on electricity 2-3 hour in each bedroom, and therefore whole school can save the electricity charge in 1 year and reach more than 80,000 yuan.
2, easy for installation, do not need zero line, only need be associated in switch series in the main line and get final product.
3, the life-span is long: by using three calculating every day, the useful life of every switch is more than 10 years.
Description of drawings:
Accompanying drawing is the schematic diagram of self-locking outage power down switch.
The direction of arrow is pointed to electrical appliance among the figure.
Execution mode:
According to the difference of bearing power, select the switch of different model for use.During use, because of its volume is little, it can be installed in the existing switch on wall, or install in place according to different situations, directly connecting with original switch gets final product.
When the unified power supply of administrative staff, because of switch has auto-lock function, lamp does not work, and when need are turned on light illumination, presses push-button switch, and lamp is promptly lighted.When next time, outage was powered again, because the relay self-locking, lamp did not still work, and repeated said process, realized purpose of energy saving.
Claims (3)
1, a kind of self-locking outage power down switch, its principal character is made up of switch sections and relay control section, and only needs phase line, does not need zero line.
2, according to the self-locking outage power down switch of claim 1, its principal character is that described switch sections is to be composed in parallel by the make contact (2) of push-button switch (1) with relay.
3, according to the self-locking of claim 1 outage power down switch, its principal character is that described relay control section is that DC voltage relay winding (6) is in parallel with electric capacity (5), again with the two ends that are connected across resistance (3) after diode (4) is connected.
