Embodiment
Below in conjunction with accompanying drawing, and other technical characteristic above-mentioned to the utility model and advantage are carried out clearly and completely
Description, it is clear that described embodiment is only section Example of the present utility model, rather than whole embodiments.
Reference picture 1, the utility model provide a kind of electric leakage alarming method by monitoring, including step S100 and step S200.
In the step s 100, the leakage data of circuit is obtained.
In step s 200, the leakage data of the circuit got and default threshold value are compared, according to circuit
Leakage data and default threshold value result of the comparison, perform actuation of an alarm.
This method is different from using earth leakage protective device.First, this method be the circuit that will be got leakage data with
Default threshold value is compared, and the mode compared has many kinds, can compare in real time, can periodically compare, also may be used
To be that historical data is compared.Secondly, this method is the knot compared according to the leakage data and default threshold value of circuit
Fruit, actuation of an alarm is performed, the mode of actuation of an alarm also there are many kinds, can be turned off circuit, can pass through Client-Prompt.
Hereinafter, row for two example two, elaborate to electric leakage alarming method by monitoring provided by the utility model.
In one embodiment, the alarming method by monitoring that leaks electricity is as shown in Figure 2.The method comprising the steps of S100 and step
S200。
In step s 110, the leakage data of circuit is obtained.
In step S220, the leakage data of the circuit got and default threshold value are compared, if circuit
Leakage data is more than default threshold value, then line disconnection.
As improvements over the prior art, the leakage data of the circuit got and default threshold value are compared.
It is because earth leakage protective device is by when detecting the leakage current more than 20 milliamperes, that is, line disconnection.
As cable, the leakage current more than 20 milliamperes be present is very common phenomenon.It is adjoint especially when cable aging
Leakage current increase, commonly greater than 20 milliamperes.Therefore, earth leakage protective device often malfunctions, and must manually push away lock after tripping,
It is difficult to promote.
In the present embodiment, the numerical value of default threshold value is adjustable, is heightened to 100 milliamperes, or even 200 milliamperes, it can subtract
Some few malfunctions.
In the present embodiment, if the leakage data of circuit is persistently more than default threshold value, cutting line within a period of time
Road.
For example, so that default threshold value is 100 milliamperes as an example, if the leakage data of cable is more than 100 milliamperes, and under
Restore to the original state again within one second.Caused by this phenomenon is probably natural cause, it is not necessary to cut off cable.If the electric leakage fluxion of cable
According to more than 100 milliamperes, and one second is continue for, possible someone gets an electric shock, it is necessary to cuts off cable.
In another embodiment, the alarming method by monitoring that leaks electricity is as shown in Figure 3.The method comprising the steps of S100 and step
S200。
In the step s 120, the leakage data of circuit is obtained.
In step S220, the leakage data of the circuit got is stored, by the leakage of the circuit of history storage
Current data and default threshold value are compared, if the leakage data of the circuit of history storage is more than default threshold value, are entered
Row alarm.
As improvements over the prior art, the leakage data of the circuit of history storage and default threshold value are compared
Compared with.It is because working as cable aging, increases along with leakage current, earth leakage protective device is often malfunctioned.
In the present embodiment, the leakage data of the circuit got is stored, the circuit of history storage can be combined
Leakage data analyzed, draw cable whether aging, so as to carry out corresponding alarm.
For example, the leakage data for the circuit that First Year obtains is 10 milliamperes, the electric leakage fluxion for the circuit that Second Year obtains
It it is 30 milliamperes according to the leakage data for 20 milliamperes, the 3rd year circuit obtained.It is old that the variation tendency of these data meets cable
The phenomenon of change, therefore, in client be relevant to the alarm of cable aging.
Prompt messages include current position of the concrete model of cable, cable etc., in order to administrative staff
Safeguard.
Reference picture 4, the utility model provide a kind of electric leakage monitor and alarm system, including detection module 100 and alarm module
200；Detection module 100 is used for the leakage data for obtaining circuit；Alarm module 200 is used for the leakage current for the circuit that will be got
Data and default threshold value are compared, and according to the leakage data of circuit and default threshold value result of the comparison, perform alarm
Action.
Specifically, detection module 100 includes ZCT.
Main line cable enters from electric leak detecting device 202, and branch cable goes out from electric leak detecting device 202, ZCT quilt
It is arranged on each branch road of main line cable and cable, the leakage current of main line cable and branch cable is detected, generation is corresponding
Leakage data.
Alarm module 200 includes electric leak detecting device 202 and Centralized Controller 201.
Electric leak detecting device 202 obtains the leakage data of main line cable and branch cable, and default threshold value is compared
Compared with if the leakage data of main line cable or branch cable is more than default threshold value, cut-out main line cable or branch road electricity
Cable.
Either, electric leak detecting device 202 obtains the leakage data of main line cable and branch cable, and to centralized Control
Device 201 is sent；Centralized Controller 201 receives corresponding leakage data and stored, by the electric leakage of the circuit of history storage
Flow data and default threshold value are compared, draw cable whether aging, so as to carry out corresponding alarm in client.
As the scheme of an expansion, personal safety is caused to prevent electric leak detecting device 202 from judging by accident, in detection of electrical leakage
Pyroelectric sensor, leakage current mutating detector and electric potential detector are integrated with equipment 202.The basis of electric leak detecting device 202
The testing result of pyroelectric sensor, leakage current mutating detector and electric potential detector determines whether human electric shock.If so,
Then just circuit is cut off without other equipment.If someone, around, pyroelectric sensor be able to certainly will detect, if gone out
Existing drain conditions, leakage current mutating detector certainly will can detect that, if human electric shock, current potential must flow into by human body
Greatly, circuit current potential is close to ground potential, when meeting three conditions simultaneously, illustrates human electric shock, electric leak detecting device 202 without
Other equipment is crossed just to cut off circuit.
Specific embodiment above, has been carried out further to the purpose of this utility model, technical scheme and beneficial effect
Describe in detail, it will be appreciated that these are only specific embodiment of the utility model, be not used to limit of the present utility model
Protection domain.Particularly point out, it is to those skilled in the art, all within the spirit and principles of the utility model, done
Any modification, equivalent substitution and improvements etc., should be included within the scope of protection of the utility model.
