In distribution box, data processing module 2 can be by wire transmission to the control information that alarm module 3 is sent or lead to
Cross and be wirelessly transferred.When equipment works normally, circuit loop closure, i.e. load circuit are powered, and the electric current of performance loop is big, equipment
Or circuit may there are trickle drain conditions；And when equipment does not work, circuit loop disconnects, i.e. load circuit powers off, therefore
Equipment will not leak electricity, but circuit may also can produce a small amount of electric leakage because of natural aging.Therefore, it is different at both
In the case of, the drain conditions of circuit are discrepant.
When the circuit of load equipment disconnects, leakage current that detection module 1 detects, only power cable is between equipment
Line electrical leakage electric current I1；During the circuit closed of load equipment, the electric current in circuit loop becomes larger, the leakage current value in circuit
I3Leakage current including line electrical leakage electric current and equipment, therefore, the leakage current value of equipment is I2=I3- I1。
Data processing module 2 analyzes the current data detected, and specific method is：If detect I3Increase, I1Also it is corresponding
Increase, and the increment value of two values is equal, i.e. I2Value does not change, then the circuit being shown to be in circuit leaks electricity, into
One step is by the current value I of detection1Compared with default first electric current safety value, if I1Less than the first electric current safety value, then control
Alarm module 3 processed is without alarm；If I1More than or equal to the first electric current safety value, then line electrical leakage report is sent to alarm module 3
Alert instruction, control alarm module 3 fail to report police into row line.If detect I3Increase, I2Also corresponding increase, but I1Do not become
Change, then the equipment being shown to be in load circuit is leaked electricity, further by the current value I of detection2Pacify with default second electric current
