Abstract
The utility model discloses a kind of circuit protection devices using light bulb current limliting, including power connection, socket panel, ammeter, light bulb, lamp holder, short switch, master switch, fuse；Socket panel, ammeter, master switch, fuse, power connection, light bulb, lamp holder series connection, short switch are in parallel with light bulb, lamp holder.In use, first making entire circuit be in series connection short switch disconnection and disconnecting master switch, select current limliting light bulb to load onto, electrical appliance to be measured is connected by plug, then plug electricity, opens master switch.If light bulb is in normal brightness, illustrate electrical equipment short circuit to be measured；On the contrary, not shining even as light is very dark, illustrate electrical appliance without short circuit, the numerical value of ammeter can be used for specifically being judged.Judge that the short switch on lamp holder without short circuit, then can be closed by electrical equipment as preliminary, because there is fuse 8 inside device, does not have to worry that machine can be burnt out.
Description
Technical field
The utility model is related to a kind of circuit protection device more particularly to a kind of circuit protection dresses using light bulb current limliting
It sets.
Background technology
The current limliting socket being currently known is mostly complicated, and measurement result is not intuitive enough, and cut-off current is unadjustable,
There is inconvenience when use.
Utility model content
The utility model provides a kind of circuit protection device using light bulb current limliting in view of the above problems, and the device is not only
The electrical equipment short circuit being connected thereto is can effectively prevent, and whether can easily tell electrical equipment short-circuit, and can
To change cut-off current.
In order to solve problem above, the utility model uses following technical solution：A kind of circuit using light bulb current limliting
Protective device, which is characterized in that including power connection, socket panel, ammeter, light bulb, lamp holder, short switch, master switch, guarantor
Dangerous silk；Socket panel, ammeter, master switch, fuse, power connection, light bulb, lamp holder series connection, short switch and light bulb, lamp holder
It is in parallel.
The socket panel is 86 socket panels.
The power connection is the three pin plug of national standard 220V.
In use, first making entire circuit be in series connection short switch disconnection and disconnecting master switch, current limliting lamp is selected
Bubble is loaded onto, and electrical appliance to be measured is connected by plug, then plugs electricity, opens master switch.If light bulb is in normal brightness, say
Bright electrical equipment short circuit to be measured；On the contrary, not shining even if light is very dark, illustrate electrical appliance without short circuit, the numerical value of ammeter
It can be used for specifically being judged.If preliminary judge that electrical equipment without short circuit, can close the short switch on lamp holder
It closes, because there is fuse inside device, does not have to worry that machine can be burnt out.
The utility model can change cut-off current by replacing different current limliting light bulbs, and pass through the light on and off of light bulb and light and shade
Whether degree intuitive judgment electrical appliance is short-circuit, simple in structure.
Description of the drawings
