When AL phase current load data of the three-phase circuit breaker 31 exceeds a tripping threshold and load shedding is required, the three-phase circuit breaker has no communication capability, and no direct remote tripping capability for the three-phase circuit breaker, but each phase line of the three-phase circuit breaker installed on a transmission line is indirectly connected with a single-phase ammeter device, and the corresponding monitoring device of the three-phase circuit breaker has communication capability, so that the tripping object of the three-phase circuit breaker 31 to be warned is not itself, but is a single-phase ammeter device indirectly connected with each phase line, the load shedding object is the three-phase circuit breaker 31 to be warned, according to a formula of a tripping rate defined by total number X of the single-phase ammeter devices directly or indirectly connected according to a computer profiling preset tripping number = 8 single-phase ammeter devices and a self-defined tripping rate set to 55%, and further, as the corresponding three-phase circuit breaker 31 to be warned has no single-phase ammeter device to be warned, the corresponding 2 steps computer device 1 is required to directly connect 5 single-phase circuit breakers to the single-phase devices, and the corresponding three-phase circuit breaker 21a is distributed to the three-phase current level 21, and the corresponding three-phase circuit breaker 1 is distributed to the real-phase current 21 is distributed to the real-time value of the three-phase circuit breaker is calculated according to a real-time value of the average value of the three-phase circuit breaker 21, and the corresponding three-phase circuit breaker is distributed to the three-phase circuit breaker is calculated to be 21, and the real-phase current value is distributed to the device is distributed to the real-time value is 21 according to a value of the real-time value of the average value is calculated to the value of the value is 21 to 20: indirect switching-off name = [ number of indirect switching-off preset by the computer of the alarmed three-phase circuit breaker being alarmed (first 0) ] X the three-phase circuit breaker being alarmed with calculated result, average real-time current load value of the alarmed phase +.total of all three-phase circuit breakers being alarmed average real-time current load value = (5-0) X23.75A +.23.75a+20.75a) ≡3, the 3 names being assigned by the 2-step computer device 1 to the total three-phase circuit breaker 22 being monitored by the 1-step computer device 2 in the 1 st order of average real-time current load value; according to the principle that when 1 three-phase breaking devices are allocated and the number of remaining breaking operations is totally equal to the number of the three-phase breaking devices, the 2-step computer device 1 allocates 2 names to the total three-phase breaking devices 21 monitored by the 1-step computer device 1, which are ordered by the 2 nd of average real-time current load values.

Since the three-phase circuit breaker 22 changes roles at this time, the allocated object is changed to the allocated object, the 3 switching names are changed to the number of switching operations to be allocated at this time, the monitoring device is changed from the 2-step computer device 1 to the 1-step computer device 2, and since the centralized devices 3 and 4 correspond to the real-time current load value=52a of the alarmed AL phase of the total three-phase circuit breaker 13 uploaded respectively, the average real-time current load value=26a is greater than the real-time current load value=43a of the alarmed AL phase of the total three-phase circuit breaker 14, the average real-time current load value=21.5a, and the calculation formula of the indirect switching names allocated to the total three-phase circuit breaker monitored by the three-phase circuit breaker and the centralized device monitored by the computer device is as follows: an indirect switching-off name = [ number of indirect switching-off preset by the computer of the three-phase switching-off device to be alerted being alerted (first 0) ] X the three-phase switching-off device to be alerted with average real-time current load value of the three-phase switching-off device to be alerted being calculated ] X sum of average real-time current load values of all three-phase switching-off devices to be alerted = (3-0) X26A +.21.5a) ≡2, the 2 names are allocated to the total three-phase switching-off devices 13 monitored by the concentration device 3 with average real-time current load value 1 rank by the 1-step computer device 2, and when the residual switching-off number is equal to 1, the 1-step computer device 2 directly allocates the residual 1 switching-off names to the total three-phase switching-off devices 14 with average real-time current load value 2 rank by the concentration device 4;

Since the total three-phase circuit breaker 13 monitored by the centralized device 3 is allocated 2 names by the 1-step computer device 2, the centralized device directly and successively issues switching-off power-off instructions by the centralized device 3 according to the rule that the real-time current load value of the corresponding-phase single-phase electric meter monitoring device is ordered from large to small and the real-time current load value 22A uploaded by the alarm phase AL 09 of the single-phase electric meter device is smaller than the real-time current load value 30A uploaded by the AL10 after the centralized device receives the corresponding switching-off names of the corresponding phases of the total three-phase circuit breaker allocated by the computer device;

since the total three-phase circuit breaker 14 monitored by the centralized device 4 is allocated 1 switching-off name by the 1-step computer device 2, the centralized device directly issues switching-off power-off instructions by the centralized device 4 according to the rule that the real-time current load value of the corresponding phase single-phase electric meter device is ordered from large to small and the order that the real-time current load value 20A uploaded by the alarm phase AL 13 of the single-phase electric meter device is smaller than the real-time current load value 23A uploaded by the 14 after the centralized device receives the corresponding phase switching-off name of the total three-phase circuit breaker allocated to be monitored by the computer monitoring service device;

Since the three-phase circuit breaker 21 converts the roles at this time, the allocated objects are changed into the allocated objects, the 2 switching names are changed into the numbers of switching operations to be allocated at this time, the monitoring device is changed from the 2-step computer device 1 into the 1-step computer device 1, and since the centralized devices 1 and 2 correspond to the alarm AL-phase real-time current load values 43A of the total three-phase circuit breaker 11 uploaded respectively, the average real-time current load value=21.5a is greater than the alarm AL-phase real-time current load value 40A of the total three-phase circuit breaker 12, the average real-time current load value=20a, and the calculation formula of the indirect switching names allocated by the three-phase circuit breaker monitored by the computer device and the total three-phase circuit breaker monitored by the centralized device is as follows: an indirect switching-off name= [ number of indirect switching-off preset by the computer gear of the three-phase circuit breaker to be alerted (first 0) of the number of indirect switching-off names of the computer gear to be alerted) X of the calculated result is allocated to the three-phase circuit breaker to be alerted (average real-time current load value of all three-phase circuit breakers = (2-0) X21.5A ++20a) ++1, the names are allocated to the total three-phase circuit breakers 11 which are ordered by the 1 st order of the average real-time current load value by the 1-step computer device 1, the 1-step computer monitoring service device 1 directly allocates the remaining 1 switching-off names to the total three-phase circuit breakers 12 which are ordered by the 2 nd order of the average real-time current load value by the centralized device, if the calculation is performed, the indirect switching-off names = (2-1) x20a = (21.5a+20a) ++20a) ++1 are allocated to the three-phase circuit breakers which are ordered by the 1-step computer device 1, and the three-phase breakers are ordered by the 2 nd order by the centralized device 2-step computer device 2;

Because the total three-phase circuit breaker 11 monitored by the centralized device 1 is distributed with 1 switching-off name by the 1-step computer device 1, the centralized device orders the real-time current load values 18A uploaded by the corresponding phase single-phase ammeter device AL phase 01 to be smaller than the real-time current load values 25A uploaded by 02, and the single-phase ammeter device 02 is directly given a switching-off instruction by the centralized device 1;

because the total three-phase circuit breaker 12 monitored by the centralized device 2 is distributed with 1 switching-off name by the 1-step computer device 1, the centralized device orders the real-time current load values 19A uploaded by the corresponding phase single-phase ammeter device AL phases 05 to be smaller than the real-time current load values 21A uploaded by 06, and the single-phase ammeter device 06 is directly given a switching-off instruction by the centralized device 2;
