And (3) a third condition: and the network nameplate of the low-voltage intelligent circuit breaker ignores the attribute parameters in the nameplate information of the powered-on and to-be-started electric equipment, and directly sends a 'standard use' instruction to the network nameplate of the powered-on and to-be-started electric equipment.
Step S3: permitted by the capacitance. Judging whether the rated capacity of the powered-on electric equipment to be started can be contained or not by the network nameplate of the intelligent circuit breaker according to the residual available capacity of the circuit breaker, and then sending a start-up instruction, a selective start-up instruction or a capacity shortage instruction to the network nameplate of the corresponding electric equipment to suspend the start-up instruction; the remaining available capacity of the circuit breaker means: the rated electrical capacity value of the circuit breaker is subtracted by the balance after the rated electrical capacity value of the powered device that is started to operate.
The allowable conditions for the capacitance include:
condition one: if the single power is on and the rated electric capacity value of the electric equipment to be started is larger than the residual available capacity of the circuit breaker, the network nameplate of the low-voltage intelligent circuit breaker sends a 'capacity shortage' instruction to the network nameplate of the power on and the electric equipment to be started, and the starting is suspended.
Condition II: if the sum of the rated electric capacity values of all the electrified and to-be-started electric equipment is larger than the residual available capacity of the circuit breaker, and no single electrified and to-be-started electric equipment is larger than the residual available capacity of the circuit breaker, the network nameplate of the low-voltage intelligent circuit breaker sends a selective start instruction to the network nameplate of all the electrified and to-be-started electric equipment. The selective start instruction means that all the powered-on electric equipment to be started cannot start running at the same time, only one of the powered-on electric equipment can be selected for starting running, and the rest powered-on electric equipment to be started can be started according to subsequent instruction information.
And (3) a third condition: if the sum of rated electric capacity values of all the powered and to-be-started electric equipment is smaller than or equal to the residual available capacity of the circuit breaker, the network nameplate of the low-voltage intelligent circuit breaker sends an instruction of 'starting' to all the network nameplates of the powered and to-be-started electric equipment.

The LED lamp is used for indicating the corresponding position as follows:
the electrical property grant command is "enabled" with a green light, and "disabled" with a red light:
the capacity grant command is used to indicate "activatable" with a green light, a yellow light indicates "selectively activated" and a red light indicates "hypo-capacity, suspend activation".
The network nameplate of the electric equipment to be started can control a locking switch, and the locking switch and a manual starting button of the electric equipment are connected in series in a starting loop of the electric equipment. On the premise that the electricity consumption property permission instruction is "enabled", when the electricity consumption capacity permission instruction is "activatable" or "selectively activated", the locking switch is closed, and the manual starting button of the electric equipment can normally start the electric equipment; when the electricity consumption property permission instruction is 'forbidden', or the electricity consumption capacity permission instruction is 'insufficient capacity', the locking switch is disconnected, and the manual starting button of the electric equipment cannot normally start the electric equipment.
Step S5: available capacity adjustment. The powered device is powered on and the powered device to be started or the powered device to be operated is stopped, and the network nameplate sends the equipment state information to the network nameplate of the intelligent circuit breaker, and the network nameplate correspondingly reduces or increases the residual available capacity value of the circuit breaker. The available capacity adjustment strategy includes:
and (3) reducing and adjusting: after the power is on and the electric equipment is started to run, the rated electric capacity value of the electric equipment is correspondingly subtracted from the residual available capacity value of the circuit breaker;
incremental adjustment: after the running electric equipment stops running, the residual available capacity value of the circuit breaker is correspondingly added with the rated electric capacity value of the electric equipment.
