Abstract
The utility model provides a kind of earth leakage protective device; leakage, breaking unit and alarm unit; described alarm unit comprises power pack, switch, buzzer, indicator light, and described power pack is connected with the output of leakage, breaking unit, and described buzzer is connected power pack with indicator light by switch.Described power pack comprises electromagnetic relay and rechargeable battery.When circuit leaks electricity; circuit disconnects by residual current protective unit; Control rechargeable battery is that buzzer and indicator light supply electric alarm; maintenance personal is reminded to keep in repair circuit; when safeguarding circuit; by the connection open circuit again of switch cutoff power pack and buzzer and indicator light, the generation noise in order to avoid it is reported to the police always.
Description
Technical field
The utility model relates to electric field, particularly relates to a kind of earth leakage protective device.
Background technology
In various civilian electric power network; earth leakage protective device is a kind of conventional equipment; its role is to monitor the leaky in electrical network; once generation leaky; namely by execution unit, open circuit is carried out to electrical network, thus the phenomenons such as various electric device electric leakage, human electric shock are prevented in time.Earth leakage protective device disclosed in Chinese patent CN102403692A, it comprises one end and is connected with power supply, the zero line that the other end is connected with load, phase line and ground wire, at zero line, phase line and ground wire are connected with linked switch, and control the tripping coil of linked switch action, amplifying circuit, controllable silicon and zero sequence current mutual inductor, it is characterized in that: armature winding one end of described zero sequence current mutual inductor is connected to zero line, the other end is connected to ground wire, between described zero line and ground wire, warning circuit is set, described warning circuit is large valued resistor and neon lamp series connection, the secondary winding of described zero sequence current mutual inductor is connected to the input of amplifying circuit, the output of amplifying circuit is connected with silicon controlled trigger electrode, controllable silicon is connected with tripping coil.But circuit can only disconnect when circuit leaks electricity by this structure, and warning reminding maintenance personal can not carry out maintenance and inspection to circuit.
Utility model content
In order to solve the problems of the technologies described above; the utility model provides a kind of earth leakage protective device; comprise leakage, breaking unit and alarm unit; described alarm unit comprises power pack, switch, buzzer, indicator light; described power pack is connected with the output of leakage, breaking unit, and described buzzer is connected power pack with indicator light by switch.
Described power pack comprises electromagnetic relay and rechargeable battery.
The beneficial effects of the utility model are: when circuit leaks electricity; circuit disconnects by residual current protective unit; Control rechargeable battery is that buzzer and indicator light supply electric alarm; maintenance personal is reminded to keep in repair circuit; when safeguarding circuit; by the connection open circuit again of switch cutoff power pack and buzzer and indicator light, the generation noise in order to avoid it is reported to the police always.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, leakage, breaking unit; 2, alarm unit; 3, power pack; 4, switch; 5, buzzer; 6, indicator light.
As shown in Figure 1, described alarm unit 2 comprises power pack 3, switch 4, buzzer 5, indicator light 6, and described power pack 3 is connected with the output of described leakage, breaking unit 1, and described buzzer 5 is connected power pack 3 with indicator light 6 by switch 4.
Described power pack 3 comprises electromagnetic relay and rechargeable battery.
When circuit leaks electricity; circuit disconnects by residual current protective unit 1; it is that buzzer 5 and indicator light 6 supply electric alarm that electromagnetic relay controls rechargeable battery; maintenance personal is reminded to keep in repair circuit; when safeguarding circuit; the connection open circuit again of power pack 3 and buzzer 5 and indicator light 6 is cut off, the generation noise in order to avoid it is reported to the police always by switch 4.
Be described in detail of the present utility model by embodiment above, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
