This application relates to the field of
electrical equipment technology and provides a method, apparatus, and
system for power-on management of load terminals, including: after detecting a first
voltage, acquiring an unlocking message from a first secondary unlocking device, the unlocking message of the first secondary unlocking device indicating whether the load terminal is connected to a control device; if it is determined from the unlocking message of the first secondary unlocking device that the load terminal is not connected to the control device, then disabling the power supply circuit for a second
voltage of the load terminal, the second
voltage being higher than the first voltage; and sending a circuit disable message to the control device, the circuit disable message indicating that the power supply circuit for the second voltage of the load terminal is disabled. This method helps reduce the probability of safety hazards arising from the activation of the second voltage power supply circuit.
