Abstract

The power supply disconnection apparatus disconnects a power supply from an electrical appliance when the monitored current falls below a disconnection level, indicating that the appliance is in a standby mode. When the appliance is operating in its non-standby mode, the power supply disconnection apparatus allows current to flow from the supply equipment to the appliance. When the appliance goes into standby mode, and requires smaller current flows from the supply equipment, then the power supply disconnection apparatus initiates a disconnection sequence which includes a grace period of time in which a return to a higher power demand is allowed, preventing disconnection from being activated. An audible or visible indication may be given prior to disconnection.

Description

Power Supply Disconnection Apparatus The power supply disconnection apparatus is a device located in an electrical power supply circuit between an appliance demanding electrical power and equipment supplying electrical power to the appliance.
When the appliance is operating in its non-standby mode, the power supply disconnection apparatus allows current to flow from the supply equipment to the appliance.
When the appliance goes into standby mode, and requires smaller current flows from the supply equipment, then the power supply disconnection apparatus initiates a disconnection sequence to stop any current flowing from the supply equipment to the appliance. This is low power detection.
The level of power at which low power detection occurs is the disconnection level.
The disconnection sequence includes a grace period of time to allow a return to higher power demand.
If higher power is not demanded at a level above the disconnection level before the grace period ends, then disconnection is activated, stopping all current from flowing from the supply equipment to the appliance.
This apparatus is fundamentally different to a residual current circuit breaker since it disconnects the power supply when the monitored current falls below a disconnection level.
Whereas a residual current circuit breaker disconnect the power supply when the monitored current rises above a disconnection level.
A power supply disconnection apparatus can have one or more disconnection levels.
A power supply disconnection apparatus can have a non-disconnection mode which would allow any low power supply situation to be ignored. The power supply disconnection apparatus *... would not initiate a disconnection sequence.
A power supply disconnection apparatus can supply one or more appliances from one or more supply equipments.
Where a power supply disconnection apparatus is supplying more than one appliance: I. *S * . the or each disconnection level may be set individually for each appliance or : * combined for two or more appliances; **: * the disconnection sequence andlor including grace periods may be set individually * for each appliance or combined for two or more appliances.
A number of examples of embodiment will now be described.
Example 1: An automatic shut-off mode in which low power consumption is detected. The power supply is disconnected immediately or after a grace period.
Example 2: The mains power switch stays on for a pre-determined time period. This time period is positioned after switch-on, or after detection of low power.
Example 3: A power disconnection warning in which an audible and/or visible indication is given prior to disconnection. A disconnection count-down is started when the disconnection warning is given. Disconnection will not occur until after the completion of the count-down.
This is a grace period to allow the user to prevent the disconnection from taking place.
Example 4: Disconnection is prevented by the user manually pressing the main activation switch. In this scenario, the grace period is reset.
Example 5: Disconnection is prevented by the appliance demanding an increased amount of power. In this scenario, the grace period is reset. *... * * * ** * *** S * * **.*
