Abstract

The utility model provides a circuit breaker with a reminding function and comprises an electromagnet and a reminding circuit. When a circuit of the circuit breaker is cut off, the electromagnet loses magnetic properties, an armature contacted with the electromagnet is pulled up by a spring to be contacted with the reminding circuit, therefore a close circuit is formed and the reminding circuit starts to work. The circuit breaker can automatically alarm users when the circuit of the circuit breaker is cut off.

Description

Circuit breaker with prompting function
Technical field
The utility model relates to a kind of circuit breaker, relates in particular to a kind of circuit breaker with prompting function.
Background technology
Circuit breaker is that a kind of can closing closed, carried and cut-off electric current under the normal loop condition, and can close close, carrying and cut-off the switching device of the electric current under the unusual loop condition (comprising short circuit condition) in official hour.It can carry out protection to power circuit and motor etc.; when serious overload or short circuit and fault such as under-voltage take place in power circuit and motor etc.; the circuit breaker automatic shutdown circuit; and behind the disjunction fault current, generally do not need to change parts; just because of its protective effect, make that circuit breaker has obtained to use widely to circuit.
But because circuit breaker is very responsive to circuit, the unusual of circuit often causes the circuit breaker open circuit, if people under non-electric situation because the circuit breaker that wire short-circuiting causes has cut off circuit, people be difficult to find out the outage root at the possible time; Add that circuit breaker generally is installed in people and is difficult to the place that contacts usually, after therefore circuit breaker cut off circuit sometimes, people did not still know.
The utility model content
The utility model provides a kind of circuit breaker with prompting function, when circuit breaker cuts off circuit, informs that by equipment such as indicator lights this circuit breaker of people has cut off circuit.
The utlity model has the circuit breaker of prompting function, comprise electromagnet, armature, insulator foot, alert circuit; Described electromagnet is arranged on the described base; Described armature is parallel to electromagnet coil and is positioned over described electromagnet top, and fixes by the insulation bracing frame, and armature one end is by insulating bar bonding conductor sheet, and the armature other end connects base by spring; The conductor piece top is two conductive contacts; Described alert circuit comprises power supply, the bulb of series connection, and alert circuit contacts with described conductor piece by two described conductive contacts and forms the closed-loop path.
Wherein, described alert circuit also comprises sound-producing device, and described sound-producing device is in parallel with described bulb.
Wherein, described power supply is a dry cell.
Wherein, described bulb is wrapped with colored shell.
The utility model can be reminded the operating state of circuit breaker easily by the mode of alert circuit is set to people.
Description of drawings
Fig. 1 is the circuit connection diagram that the utlity model has the circuit breaker of prompting function.
Embodiment
With reference to Fig. 1, the circuit breaker that the utlity model has prompting function is described in detail and describe by specific embodiment, so that better understand the utility model, but following embodiment remarkable the utility model scope.
The utlity model has the circuit breaker of prompting function, except that conventional circuit breaker, also comprise electromagnet 2, armature 3, insulator foot 11 and alert circuit.
Electromagnet 2 is arranged on the described base, and the coil of electromagnet 2 connects circuit breaker power circuit 1; Armature 3 is parallel to electromagnet coil and is positioned over electromagnet 2 tops, and fixing by insulation bracing frame 10, and armature 3 one ends are by insulating bar 4 bonding conductor sheets 5, and conductor piece 5 tops are two conductive contacts 6; Described alert circuit comprises power supply, the bulb 7 of series connection, and alert circuit contacts with conductor piece 5 by two conductive contacts 6 and forms the closed-loop path.
When circuit breaker does not cut off circuit, power circuit 1 energising, electromagnet 2 produces magnetic, thus armature 3 is attracted to make conductor piece 5 to leave conductive contact 6 by electromagnet 2, and alert circuit disconnects, and bulb 7 is not worked.
The other end of armature 3 connects base 11 by spring 8, and when circuit breaker cut off circuit, power circuit 1 was no longer switched on, electromagnet 2 loses magnetism, and under spring 8 pulling force, armature 3 breaks away from electromagnet 2, conductor piece 5 contacts with conductive contact 6, alert circuit closure, bulb 7 work; Thereby play reminding effect.
Above-mentioned circuit breaker with prompting function can also be in alert circuit a sound-producing device 9 in parallel with bulb, to play better prompting function.Outside the bulb 7 colored shell can also be set, it is colored, more bright-coloured making light color, and is found easily.Battery can be selected dry cell for use.
More than specific embodiment of the utility model is described in detail, but it is as example, is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of being done under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.

Claims (4)

1. the circuit breaker with prompting function is characterized in that, comprises electromagnet, armature, insulator foot, alert circuit; Described electromagnet is arranged on the described base; Described armature is parallel to electromagnet coil and is positioned over described electromagnet top, and fixes by the insulation bracing frame, and armature one end is by insulating bar bonding conductor sheet, and the armature other end connects base by spring; The conductor piece top is two conductive contacts; Described alert circuit comprises power supply, the bulb of series connection, and alert circuit contacts with described conductor piece by two described conductive contacts and forms the closed-loop path.
