Description
Technical field
The utility model relates to a kind of overload protection arrangement, particularly, relates to a kind of overload protection arrangement with alarm function.
Background technology
At present, for avoiding the too high softening phenomenon of causing danger of electric wire that causes of indoor electrical power, in the general family, all can dispose fuse at the battery main switch place.Because the fusing point of fuse is low than electric wire (copper cash), therefore when overload, high heat can be earlier with blown fuse, to stop power supply, danger such as avoids causing that electric wire cocks off.Yet fuse is in case fusing just must be changed again and buy more new using, and this is quite inconvenient something for resident family.Therefore, most battery main switch place has used the spring switch to replace fuse.Its principle is when overload, and the spring switch is upspring automatically and cut off current supply circuit, if desire to restart when powering, just the spring switch must be dialled go back to the position of power supply.Though this design can be avoided danger such as overload causes that electric wire cocks off, service time one is of a specified duration, and the spring switch is just in case the elastic fatigue phenomenon takes place, and consequence is hardly imaginable really.Therefore above-mentioned overload protection arrangement is difficult to can be rated as practicality.In addition, resident family can't learn that present amount of power supply is safe, approaching overload or the state that has transshipped, thereby continues to connect electricity and use, and danger is also just followed.
Summary of the invention
Because above-mentioned shortcoming, it does not reach perfection creator's thoughts, exhausts the concentrated research of its intelligence then and overcomes, and is engaged in this industry accumulating experience for many years with it, and then develops a kind of overload protection arrangement, to reach the effect that has more caution in overload protection.
Therefore, main purpose of the present utility model is to design a kind of overload protection arrangement, can reach the effect that has caution concurrently.
For reaching above-mentioned purpose, realization technology of the present utility model is as follows:
A kind of overload protection arrangement comprises: the power detecting unit is used to detect the power data that external power supply device is exported; Processing unit, itself and this power detecting unit electric property coupling, and be preset with the Power Limitation value; Breaking units with this processing unit electric property coupling; And with the caution unit of this processing unit electric property coupling; Wherein, when this power data during less than this Power Limitation value, this processing unit is controlled this caution unit and is produced first alerting; When this power data during greater than this Power Limitation value, this processing unit is controlled this caution unit and is produced second alerting, and starts this breaking units, continues power supply to stop this external power supply device.
Therefore, overload protection arrangement of the present utility model can provide alarm function in overload protection.

Embodiment
For above-mentioned and other purpose of the present utility model, feature and effect can be become apparent, existing by following specific embodiment, and cooperate appended graphicly, the utility model is described in detail as follows.
See also Fig. 1 and Fig. 2; be respectively the allocation plan and the calcspar of the utility model overload protection arrangement; as shown in the figure: overload protection arrangement 20 of the present utility model mainly is configured between external power supply device (civil power) 10 and the socket 30 and uses, and also configurablely uses on the extended line socket.This overload protection arrangement 20 mainly comprises power detecting unit 23, processing unit 22, breaking units 25 and caution unit 24.This processing unit 22 can determine whether driving this breaking units 25 according to these power detecting unit 23 measured power datas, and the caution degree that determines this caution unit 24.
For instance, power detecting unit 10 and external power supply device (civil power) 10 electric property couplings, and detect the power data that this external power supply device 10 is exported.22 of this processing units and these power detecting unit 23 electric property couplings, and be preset with Power Limitation value (as 1500 watts).This caution unit 24 and this breaking units 25 all with these processing unit 22 electric property couplings, and this to warn unit 24 be light-emitting diode (LED) or loud speaker.The power output data that record present external power supply device (civil power) 10 when power detecting unit 23 are during less than this Power Limitation value, this processing unit 22 will control this caution unit 24 produce first alerting (as light-emitting diode is not worked or only flicker once and loud speaker is not sounded or serge one only); And when this power data during greater than this Power Limitation value (1500 watts), this processing unit 22 will be controlled this caution unit 24 and produce second alerting (as make the flicker that light-emitting diode do not stop and make loud speaker send continuous sound), and start this breaking units 25, continue power supply to stop this external power supply device 10.Can thus, when when outage, the user learn why be de-energized by seeing through this caution unit 24, is power failure or has transshipped? and then do optimal processing.
In addition; for making overload protection arrangement 20 of the present utility model have better alarm function; this caution unit 24 more includes the first indication cresset 241, the second indication cresset 242, the 3rd indication cresset 243 and the 4th indication cresset 244, and this Power Limitation value also is divided into first to fourth power level value (500W, 1000W, 1300W, 1500W) by correspondence.When the power output data of external power supply device (civil power) 10 during less than the first power level value (500W), processing unit 22 promptly drives the first indication cresset 241 in the caution unit 24 and sends radiance as green, with the safety that shows that present electricity consumption is suitable; When the power output data of external power supply device (civil power) 10 are between the first power level value (500W) and the second power level value (1000W), processing unit 22 promptly drives caution second in unit 24 indication cresset 242 and sends radiance as yellow, higher a little to show present electricity consumption, but also be in the safe scope; When the power output data of external power supply device (civil power) 10 are between the second power level value (1000W) and the 3rd power level value (1300W), processing unit 22 promptly drives caution the 3rd in unit 24 indication cresset 243 and sends radiance as redness, higher to show present electricity consumption, can not increase load again and use; And when the power output data of external power supply device (civil power) 10 during greater than the 4th power level value (1500W), processing unit 22 promptly drives caution the 4th in unit 24 indication cresset 244 and sends radiance as flash red, showing that present electricity consumption transships, and stopped this external power supply device 10 and continued power supply.Thus, resident family or user can see through the electric power thus supplied that 10 pairs of loads of present external power supply device are judged in caution unit 24, and consideration is adjusted the quantity of load, quite practicality.
In sum, truly feasible by overload protection arrangement of the present utility model, and improved the various shortcomings of known technology, real for innovation and have the utility model of practicality, and have novelty and creativeness, meet the legal important document of utility model patent fully.
The above is preferred embodiment of the present utility model only, is not in order to limit claim of the present utility model; All other do not break away from the equivalence of being finished under the spirit that the utility model discloses and changes or modify, and all should be included in the scope of following claims.
