Non-electricity protector.
Background technology
Currently, in many household lines, often there is leaky, but user is difficult to find electric leakage in a short time
Position, thus emergency service can not be carried out under the premise of not influencing safe to use.This is also that much users do not install leakage at present
Non-electricity protector, and a major reason of common miniature circuit breaker is selected, such as some electrical equipments leakage current itself is more than
30mA, if underground water draws water water pump, because can not normal power supply, it is necessary to change common miniature circuit breaker into, earth leakage protective device is caused to make
It is suffered restraints with range.
Therefore it needs one kind not only can be with earth leakage protective, but also can make for user with the Household electricity leakage protection device of electric leakage flow-thru electrode
With improving the use scope of Household electricity leakage protection device, more reliable guarantee provided for Electrical Safety.
Invention content
To solve the above problems, the utility model discloses a kind of Household electricity leakage protection device that can be closed a floodgate with leakage current,
Including upper cover and pedestal；The upper cover includes trial jump key, reset key, operation handle, communication interface；The pedestal is controlled comprising CPU
Device, buckle releaser and current transformer processed；The trial jump key, current transformer, buckle releaser, communication interface and cpu controller are electrically connected
It connects；The cpu controller sends electric current, voltage signal automatically, controls the action of buckle releaser；The cpu controller is equipped with logical
Interrogate module.
When, there are when leakage current, cpu controller reads the output current value of current transformer, judges to leak electricity in load circuit
The size of flow valuve, cpu controller control buckle releaser tripping of whether threading off according to the size of leakage current value.
After tripping there are leakage current in load circuit, closing by hand is carried out to operation handle, cpu controller is not to threading off
Device sends electric current, voltage signal, and buckle releaser is failure to actuate, and Household electricity leakage protection device will not again be jumped because of with the presence of leakage current
Lock ensures that Household electricity leakage protection device can be worked with normal power-up, and cpu controller automatically records the leakage current value in load circuit.
When being superimposed a new electric leakage again in load circuit, cpu controller reads the output current of current transformer
Value judges that the size for increasing leakage current value newly, cpu controller are carried out according to whether newly-increased leakage current threads off to trip to buckle releaser
Control.
After the deactivating of electric leakage equipment, leakage current disappears, and creepage protection function automatically restores to original state, i.e., have again and be more than
When the leakage current of 30mA, Household electricity leakage protection device can normally trip.
Communication module on cpu controller, which can utilize, wirelessly to carry out data transmission, and communication interface can utilize
Wired mode carries out data transmission.
The utility model has the advantages that：Pass through the control of cpu controller so that Household electricity leakage protection device can both play leakage
The function of electric protection, it is also possible that there are Household electricity leakage protection devices when leakage current to be greatly improved with normal power supply in circuit
The flexibility that Household electricity leakage protection device uses expands Household electricity leakage protection device to farthest protect life security
Use scope improves the use popularity rate of Household electricity leakage protection device.

Specific implementation mode
A kind of Household electricity leakage protection device that can be closed a floodgate with leakage current provided by the utility model, referring to Figures 1 and 2, packet
Include upper cover 1 and pedestal；The upper cover 1 includes trial jump key 2, reset key 3, operation handle 4 and communication interface 8；The pedestal includes
Cpu controller 7, buckle releaser 5 and current transformer 6；The trial jump key 2, current transformer 6, buckle releaser 5, communication interface 8 with
Cpu controller 7 is electrically connected.
Specifically, when, there are when leakage current, cpu controller 7 reads the output current of current transformer 6 in load circuit
Value, judges whether leakage current value is more than 30mA, and if more than 30mA, cpu controller 7 sends electric current, voltage signal to buckle releaser 5,
Household electricity leakage protection device normally trips, and plays the role of earth leakage protective.Less than 30mA, then Household electricity leakage protection device does not trip, just
Often it is powered on.
Further, it closes a floodgate manually to operation handle 4 at this time, cpu controller 7 does not send electric current, electricity to buckle releaser 5
Signal, buckle releaser 5 is pressed to be failure to actuate, Household electricity leakage protection device will not again trip because of loaded line with the presence of leakage current, protect
The output current value of current transformer 6 can be read automatically with normal power-up, cpu controller 7 by demonstrate,proving Household electricity leakage protection device, and record is negative
Carry the leakage current value in circuit.
Further, when being superimposed a new electric leakage again in load circuit, cpu controller 7 reads current transformer 6
Output current value, judge the size for increasing leakage current value newly, if more than 30mA, cpu controller 7 sends electric current, electricity to buckle releaser 5
It presses signal, buckle releaser 5 to act, Household electricity leakage protection device is made to trip, increase leakage current newly and be less than 30mA, then Household electricity leakage protection device is not
Tripping, normal work.
Further, after the deactivating of electric leakage equipment, leakage current disappears at this time, and creepage protection function automatically restores to initial shape
State after having electric leakage equipment to come into operation again, causes the leakage current value in load circuit to be more than 30mA, cpu controller 7 is to threading off
Device 5 sends electric current, voltage signal, and Household electricity leakage protection device can normally trip.
Further, wirelessly carried out data transmission using the communication module on cpu controller 7, or utilized logical
Communication interface carries out data transmission in a wired manner, to provide valid data with the intelligent management of radio area.
Technological means disclosed in the utility model is not limited only to the technological means disclosed in the above embodiment, further includes
By the above technical characteristic arbitrarily the formed technical solution of combination.
