Description

Melt fault alarm
Technical field
The utility model provides a kind of melt fault alarm, belongs to fuse alarm device field.
Background technology
In order to prevent electric current excessive thus burn out the element of electronic installation inside, often fuse can be installed additional at plant-grid connection place, wire in fuse at high temperature can fuse, thus circuit is disconnected, ensure the safety of electric component, but when there is non-serviceable problem in the equipment that structure is comparatively complicated, often need to investigate accident one by one, if but problem blown fuse, then only need to change fuse, but maintainer has no way of learning, still need the problem investigating each parts one by one, greatly reduce maintenance efficiency.
Utility model content
The utility model object is to provide a kind of melt fault alarm, when meeting after fuse blows and alarm, improves the maintenance efficiency of attendant.
Melt fault alarm described in the utility model; comprise fuse; fuse is installed on live wire; be provided with warning device and controllable silicon; controllable silicon one end is connected on live wire; relative to fuse upper end position, the controllable silicon other end is connected to zero line or another phase firewire mains side by warning device, and controllable silicon gate electrode connects anti-paralleled diode protective resistance successively and electric capacity is connected to the below of live wire relative to fuse.
Described melt fault alarm, be applicable to normal household electricity, when normal power-up, electric capacity is in charged state, and anti-paralleled diode is due to its conducting state, normal household electricity cannot pass through, can be blocked by anti-paralleled diode, make silicon controlled gate electrode no power, gate electrode no power, then controllable silicon two ends not conducting, warning device does not work, when fuse is because circuit occurring abnormal electric current causes it to fuse, dead electricity is caused because fuse disconnects below fuse, in this case the electromotive force of electric capacity can higher than other point, thus electric discharge, the voltage of capacitor discharge is very low, and after protective resistance dividing potential drop, quite low by the voltage of anti-paralleled diode, be enough to make it pass through anti-paralleled diode, controllable silicon gate electrode is obtained electric, controlled silicon conducting, warning device obtains electrician and does to remind maintenance personal, make when fuse disconnection causes electric equipment to work, can learn at once, and change, add maintenance efficiency greatly.
Described melt fault alarm, warning device comprises buzzer and lamp, and buzzer and lamp are connected in parallel between controllable silicon and zero line.Make warning device carry out sound and light alarm, make attendant learn the very first time and find, further increase maintenance efficiency, and lamp is positioned at fuse position, make non-attendant after pinpointing the problems, also can find fuse according to lamp position and change.
Described melt fault alarm, lamp is stroboscopic lamp.Stroboscopic lamp is more obvious relative to common lamp, makes attendant be more prone to find.
The utility model compared with prior art beneficial effect is:
Described melt fault alarm, be applicable to normal household electricity, when normal power-up, electric capacity is in charged state, and anti-paralleled diode is due to its conducting state, normal household electricity cannot pass through, can be blocked by anti-paralleled diode, make silicon controlled gate electrode no power, gate electrode no power, then controllable silicon two ends not conducting, warning device does not work, when fuse is because circuit occurring abnormal electric current causes it to fuse, dead electricity is caused because fuse disconnects below fuse, in this case the electromotive force of electric capacity can higher than other point, thus electric discharge, the voltage of capacitor discharge is very low, and after protective resistance dividing potential drop, quite low by the voltage of anti-paralleled diode, be enough to make it pass through anti-paralleled diode, controllable silicon gate electrode is obtained electric, controlled silicon conducting, warning device obtains electrician and does to remind maintenance personal, make when fuse disconnection causes electric equipment to work, can learn at once, and change, add maintenance efficiency greatly.
Described warning device, makes warning device carry out sound and light alarm, makes attendant learn the very first time and find, further increase maintenance efficiency, and lamp is positioned at fuse position, make non-attendant after pinpointing the problems, also can find fuse according to lamp position and change.
Described lamp, stroboscopic lamp is more obvious relative to common lamp, makes attendant be more prone to find.
Accompanying drawing explanation
Fig. 1 is the utility model electrical schematic diagram.
In figure: 1, fuse; 2, warning device; 3, controllable silicon; 4, anti-paralleled diode; 5, protective resistance; 6, electric capacity; 7, buzzer; 8, lamp.
Embodiment
Below in conjunction with the utility model, the utility model embodiment is described further:
Embodiment: as shown in Figure 1; melt fault alarm described in the utility model; comprise fuse 1; fuse 1 is installed on live wire; be provided with warning device 2 and controllable silicon 3, controllable silicon 3 one end is connected on live wire, relative to fuse 1 upper end position; controllable silicon 3 other end is connected to zero line or another phase firewire mains side by warning device 2, and controllable silicon 3 gate electrode connects anti-paralleled diode 4, protective resistance 5 and electric capacity 6 successively and is connected to the below of live wire relative to fuse.
Embodiment 2: on the architecture basics described in embodiment 1, warning device 2 comprises buzzer 7 and lamp 8, and buzzer 7 and lamp 8 are connected in parallel between controllable silicon 3 and zero line, and lamp 8 is stroboscopic lamp and buzzer 7 is ticking.
Operating procedure and operation principle:
Described melt fault alarm, be applicable to normal household electricity, when normal power-up, electric capacity 6 is in charged state, and anti-paralleled diode 4 is due to its conducting state, normal household electricity cannot pass through, can be blocked by anti-paralleled diode 4, make the gate electrode no power of controllable silicon 3, gate electrode no power, then controllable silicon 3 two ends not conducting, warning device 2 does not work, when fuse 1 is because circuit occurring abnormal electric current causes it to fuse, dead electricity is caused because fuse 1 disconnects below fuse 1, in this case the electromotive force of electric capacity 6 can higher than other point, thus electric discharge, the voltage that electric capacity 6 discharges is very low, and after protective resistance 5 dividing potential drop, quite low by the voltage of anti-paralleled diode 4, be enough to make it by anti-paralleled diode 4, controllable silicon 3 gate electrode is made to obtain electric, controllable silicon 3 conducting, warning device 2 obtains electrician and does to remind maintenance personal, make when fuse 1 disconnection causes electric equipment to work, can learn at once, and change, add maintenance efficiency greatly.
