Abstract
The utility model discloses a fusing alarm for a fuse. The fusing alarm for the fuse comprises a first wire connecting terminal, a second wire connecting terminal, a high-voltage capacitor, a low-voltage capacitor, a current-limiting resistor, and an alarm. The first wire connecting terminal and the second wire connecting terminal are respectively connected with two ends of the fuse. The high-voltage capacitor and the low-voltage capacitor are connected in series between the first wire connecting terminal and the second wire connecting terminal. The alarm is connected in parallel to two ends of the low-voltage capacitor, and is used to send the signals that the fuse is burnt out. The fusing alarm for the fuse not only has a simple structure, but also can immediately send the signals that the fuse is burnt out continuously after the fuse is burnt out, and greatly improves the monitoring automation degree of a power consuming or power feeding system.
Description
Technical field
The utility model relates to a kind of indicating device, especially a kind of fuse blows alarm.
Background technology
At present, people like the safe operation of transformer, switch, motor etc., mostly are connected in series various fuse in order to ensure various power consumption equipments in its loop.Though it is simple in structure that these fuses have, easy to use, but avoid effectively transshipping or short circuit current to by the harm of protection equipment, exist weak point also, at first, whether not directly perceived the fusing of most fuses is, brought inconvenience for operation and maintenance; Secondly; Though indivedual fuses are arranged, the effect of the spring that has because of himself like the fusing of the fuse switch in the high-tension circuit makes fusing whether very directly perceived, and so it is the same with other fuse; The defective that can not automatically provide the signal of telecommunication after the fusing is also arranged simultaneously; Be unfavorable for effective monitoring, so there is defective in prior art, needs to improve fuse.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure for overcoming weak point of the prior art, can send a kind of fuse blows alarm of fusing signal.
For solving the technical problem of the utility model; The technical scheme that is adopted is: a kind of fuse blows alarm; Comprise first binding post, second binding post, high-voltage capacitor, secondary capacitor, current-limiting resistance, alarm; First binding post, second binding post are connected with the fuse two ends respectively, and high-voltage capacitor, secondary capacitor are connected in series between first binding post, second binding post, and current-limiting resistance is in series with alarm and is connected; Alarm is connected in parallel in the two ends of secondary capacitor, is used to send the signal of fuse blows;
Fuse is fuse switch or noninductive current limiting fuse.
Beneficial effect with respect to prior art is, and is not only simple in structure, can also after fuse blows, send the signal of oneself fusing of fuse immediately constantly, greatly improved the monitoring automation degree of electricity consumption or electric power system.
Description of drawings
Figure l is a kind of basic structure sketch map of the utility model.
Embodiment
Be described in further detail below in conjunction with the optimal way of accompanying drawing the utility model.
Shown in Fig. 1; A kind of fuse blows alarm comprises that first binding post 1, second binding post 6, high-voltage capacitor 5, secondary capacitor 3, current-limiting resistance 2, alarm 4, the first binding posts 1, second binding post 6 are connected with fuse 7 two ends respectively; High-voltage capacitor 5, secondary capacitor 3 are connected in series between first binding post 1, second binding post 6; Current-limiting resistance 2 is in series with alarm 4 and is connected, and alarm 4 is connected in parallel in the two ends of secondary capacitor 3, is used to send the signal of fuse 7 fusing; Fuse 7 is fuse switch or noninductive current limiting fuse, and alarm 4 is a LED light-emitting diode or a toy trumpet.
During use, the two ends that only need first binding post 1 and second binding post 6 to be connected to fuse 7 respectively get final product, and when fuse 7 did not fuse, alarm 4 no signals were exported; After when fuse 7 fusing; The voltage at fuse 7 two ends is added on the high-voltage capacitor 5 and secondary capacitor 3 that is connected in series; The circuit of alarm 4 and the two ends of secondary capacitor 3 form electric loop at this moment; Make the LED light-emitting diode send light signal or toy trumpet sends the sound, indicate oneself fusing of fuse.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
Claims (2)
1. fuse blows alarm; It is characterized in that: comprise first binding post, second binding post, high-voltage capacitor, secondary capacitor, current-limiting resistance, alarm; First binding post, second binding post are connected with the fuse two ends respectively; High-voltage capacitor, secondary capacitor are connected in series between first binding post, second binding post; Current-limiting resistance is in series with alarm and is connected, and alarm is connected in parallel in the two ends of secondary capacitor, is used to send the signal of fuse blows.
2. according to the described fuse blows alarm of claim l, it is characterized in that: fuse is fuse switch or noninductive current limiting fuse.
