Abstract
The utility model relates to a circuit overload automatic alarm device. The device comprises a circuit overload automatic cutout. The device is special in that an output end of the circuit overload automatic cutout is connected in series with a power transformer, and output ends of the power transformer are connected in series with an indicator light, an electromagnetic cut-out, and a resistor. An armature of the electromagnetic cut-out is provided with a contact switch, and a fixed contact of the contact switch is connected with an emergency alarm bell. The other end of the emergency alarm bell is connected in series with a movable contact of the contact switch and a low-voltage power supply. The device can prevent occurrence of electricity accidents, thereby preventing casualties and economic losses caused by overloaded electricity utilization.
Description
Technical field
The utility model relates to circuit protection device, particularly circuit excess load autoalarm.
Background technology
, often there is people's random pull the wire privately in city, particularly fringe area that we live, private connects high-power electric appliance, causes circuit excess load, causes circuit, electrical equipment destruction, even cause the generation of the serious security incidents such as fire, cause casualties and great economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of avoiding and destroys because overload power utilization causes electrical equipment, even causes the generation of the serious security incidents such as fire, causes casualties and the circuit excess load autoalarm of economic loss greatly.
Technical solution of the present utility model is circuit excess load autoalarm, comprise circuit excess load automatic cutout, the output of described circuit excess load automatic cutout is serially connected with power transformer, the output of described power transformer and indicator light, electromagnetic breaker and resistance are connected in series, on the armature of electromagnetic breaker, be provided with contact switch, the fixed contact of this contact switch is connected with emergency alarm bell, and the other end of emergency alarm bell and the moving contact of contact switch and low-tension supply are connected in series.
Above-described low-tension supply can be storage battery or dry cell.
The output of circuit excess load automatic cutout of the present utility model can be serially connected with power transformer, and the output of described power transformer and indicator light, electromagnetic breaker and resistance are connected in series.
Operation principle of the present utility model is when having a people random pull the wire, private connect high-power electric appliance privately, causes circuit excess load
,circuit excess load automatic circuit breaker opens circuit, and automatically cuts off immediately power supply circuits.After the transformation being connected with way circuit, low-voltage regulated power supply opens circuit simultaneously, indicator light---green indicating lamp extinguishes immediately to utilize the circuit normal operation of low-voltage regulated power supply work after transformation, cause the electromagnet being connected with circuit normal operation indicator light (green indicating lamp) to open circuit, electromagnet loses magnetism, armature is had no attraction, and armature pops up under the pulling force effect of spring, and moving contact below contacts with fixed contact above, connect warning circuit, bell ring is reported to the police.About management and maintenance department, user receive after reporting to the police, just can investigate at once, correct a mistake, on-call maintenance, avoids the generation of Electrical Safety accident to greatest extent, thus the casualties of avoiding and economic loss.
The utility model has the advantages that the generation that can avoid Electrical Safety accident, thereby avoid causing casualties and economic loss because of overload power utilization.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Referring to Fig. 1, circuit excess load autoalarm comprises circuit excess load automatic cutout 1, the output of described circuit excess load automatic cutout 1 is serially connected with power transformer 9, the output of described power transformer 9 and indicator light 3, electromagnetic breaker 4 and current-limiting resistance 2 are connected in series, on the armature 5 of electromagnetic breaker 4, be provided with contact switch, the fixed contact 8 of this contact switch is connected with emergency alarm bell 6, and the other end of emergency alarm bell 6 and the moving contact of contact switch 7 are connected in series with low-tension supply 10.
Above-described low-tension supply 10 is dry cells, can use storage battery, also can use the low-voltage regulated power supply after transformation.
