With reference to RCD acting characteristic automatic detection flow chart as shown in Figure 4, residual current is moved
The specific steps for making protector acting characteristic automatic testing method are explained.
First, carry out the detection of RCD acting characteristic to prepare, specially count residual current acting and protect
This month tripping operation record of device storage is protected, the information of " this month existing trip operation record " is sent if tripping operation record is stored with simultaneously
Terminate the detection of this RCD acting characteristic to prepare, if record is not tripped, into next step；
Secondly, regulated ground resistance is detected, and is specially read default in RCD " remaining dynamic
Make current value " data, according to the scope of " residual action current value " data, corresponding grounding resistance is automatically adjusted, and will detection
Circuit is correspondingly connected to A phases either B phases or C phases；
It is then detected that and collect RCD acting characteristic detection data, specifically include detection before data,
Data, RCD acting characteristic therein detection data include U after data and detection in detectiona、Ub、Uc、
Ia、Ib、Ic, residual current IΔnWith switching value KGL data；
Finally, data before the detection to RCD acting characteristic, data after data and detection in detection
Contrasted and judged, if meeting Ua1>0、Ua2=0, Ua3>0、Ub1>0、Ub2=0, Ub3>0、Uc1>0、Uc2=0, Uc3>0、Ia1>
0、Ia2=0, Ia3>0、Ib1>0、Ib2=0, Ib3>0、Ic1>0、Ic2=0, Ic3>0、IΔn1>0、IΔn2=0, IΔn3>0、KGL1=1,
KGL2=0 and KGL3=1 condition, then " detection of RCD acting characteristic is normal " information is sent, and terminate this
Acting characteristic detection prepares, if do not met, " detection of RCD acting characteristic is abnormal, it is necessary to existing for transmission
Field is verified " information, and terminate the detection of this acting characteristic and prepare.
Further, it is specially：
Step 1：According to the timing set in CPU processor, start the inspection of RCD acting characteristic
Survey and prepare, elimination CPU processor is data cached, into RCD acting characteristic testing process.
Step 2：CPU processor is tripped using this month in 485 port communications statistics RCD memory
Record, prepare to elapse forward day 29 and counted according to acting characteristic detection, as a result for more than or equal to " 1 " when, into step
3, otherwise into step 4.
Step 3：Trigger gsm module and send " this month existing trip operation record " short message, and terminate into step 17 link
The detection of this RCD acting characteristic prepares.
Step 4：Default " residual action current value " data in RCD are read by 485 ports.
Step 5：It is 50~75mA to read " residual action current value " data, and it is 1k that experimental rig, which automatically adjusts grounding resistance,
Ω shelves, detection circuit are connected to A phases；During 100~150mA, regulated ground resistance is 1.5k Ω shelves, and detection circuit is connected to B phases；200
During~300mA, adjust to 2k Ω shelves, detection circuit and be connected to C phases.During if greater than 300mA, experimental rig sends instruction first,
The residual action current value of RCD is adjusted to 300mA, then adjusts and is carried out on corresponding grounding resistance again
Detection.
Step 6：Data Collection instructs before sending the detection of RCD acting characteristic, gathers Ua、Ub、Uc、
Ia、Ib、Ic, residual current IΔnIt is stored in switching value KGL data in CPU processor caching, and presses Ua1、Ub1、Uc1、Ia1、Ib1、
Ic1、IΔn1And KGL1Form stores.
Step 7：According to CPU processor deliberate action Characteristics Detection timing, by detection circuit phase sequence by relay line
Circle carries out simulating residual current super default " residual action current value " with 0.2s conduction times through connecing resistance to grounding body
80% detection.
Step 8：Data Collection instruction is sent after waiting 10~20s, gathers Ua、Ub、Uc、Ia、Ib、Ic, residual current IΔnWith
Switching value KGL data are stored in CPU processor caching, and press Ua2、Ub2、Uc2、Ia2、Ib2、Ic2、IΔn2And KGL2Form stores,
0.3s and 0.5s circle collections are then using the data replaced in CPU processor caching.
Step 9：Judge Ua2=0, Ub2=0, Uc2=0 and KGL2Whether=0 condition meets, and does not meet by 0.3s and 0.5s
ON time return to step 10 or step 11 successively, meet and then enter step 12.
Step 10：Relay coil is carried out with 0.3s conduction times through connecing resistance to grounding body by detection circuit phase sequence
Simulate residual current super default " residual action current value " 80% detects, then enter back into step 8 and step 9 Data Collection with
Sentence link, do not meet into step 11, it is eligible to enter step 12.
Step 11：Relay coil is carried out with 0.5s conduction times through connecing resistance to grounding body by detection circuit phase sequence
Simulate residual current super default " residual action current value " 80% detects, then according to step 8 and step 9 Data Collection with sentence
Break to sentence and do not meet also, ineligible progress step 16, meet and then enter step 12.
Step 12：Data Collection instruction is sent after 60s again, gathers Ua、Ub、Uc、Ia、Ib、Ic, residual current IΔn2With open
Pass amount KGL data are stored in CPU processor caching, and press Ua3、Ub3、Uc3、Ia3、Ib3、Ic3、IΔn3And KGL3Form stores.
Step 13：In being cached according to CPU processor detect before, detection in (10~20s gathered datas) and detection after (60s
The data of collection afterwards) contrasted and judged.
Step 14：If meet Ua1>0、Ua2=0, Ua3>0、Ub1>0、Ub2=0, Ub3>0、Uc1>0、Uc2=0, Uc3>0、Ia1>
0、Ia2=0, Ia3>0、Ib1>0、Ib2=0, Ib3>0、Ic1>0、Ic2=0, Ic3>0、IΔn1>0、IΔn2=0, IΔn3>0、KGL1=1,
KGL2=0 and KGL3=1 condition then enters step 15, does not meet into step 16.
Step 15：Trigger gsm module and send " detection of RCD acting characteristic is normal " short message, and enter
Step 17 terminates the detection of this acting characteristic and prepared.
Step 16：Triggering gsm module transmission, " detection of RCD acting characteristic is abnormal, it is necessary to live
Verify " short message, and enter step 17 and terminate the detection preparation of this acting characteristic.
Step 17：By CPU processor cache in data conversion storage in data storage, and remove data cached.
