Power-saving controller for automatically detecting states of power device and supply network and delaying outage

Abstract

The invention discloses a power-saving controller for delaying outage. The power-saving controller is capable of automatically detecting shutdown or abnormal power-off signals of a power device with high power and enables the power device to be disconnected with a supply network in the set time, and the requirement of users for using a power device with small power in a short time can be met while the power is saved and used safely. After being triggered, at first, the power-saving controller connects the supply network with the power device, and meanwhile, an outage delay progress in the power-saving controller starts working; the outage delay progress is used for timing, and in the timing process, if the power of a supply line is smaller than a preset threshold value all the time, the power device and the supply network are disconnected when the delay time t is reached; if the power is larger than the threshold value, the outage delay progress is automatically stopped; hereafter, the power of the supply line continues to be detected, and once the power is smaller than the threshold, the outage delay progress is restarted again.

Description

technical field [0001] The invention relates to the fields of safe electricity utilization, energy saving and environmental protection, and in particular to an electricity-saving controller that automatically detects the state of an electricity-consuming device and a power grid and can automatically cut off power after a delay. Background technique [0002] Electric devices such as TVs, computers, speakers, printers, game consoles, etc. are in a standby state all year round if the power supply is not cut off when they are not working. LCD TVs, game consoles, computers, printers, speakers and other equipment consume between 1W and 7W of power when they are in standby mode. Moreover, although some electrical equipment is powered off, its internal circuits are not completely isolated from the power grid. If maintenance is performed without unplugging the plug, there will be a danger of electric shock. In addition, some electronic components will accelerate aging if they work fo...

Problems solved by technology

Moreover, although some electrical equipment is powered off, its internal circuits are not completely isolated from the power grid. If maintenance is performed without unplugging the plug, there will be a danger of electric shock. In addition, some electronic components will accelerate aging if they work for a long time , or even suddenly damaged to cause fire and other safety accidents

[0003] Some low-power electrical devices (such as electric soldering irons, chargers) have great potential safety hazards if they are not in use and powered on for a long time after charging.

For example, when a charger quickly charges a battery (such as a mobile phone battery), it consumes less than 7W of power, but the charging can be completed in 2 to 3 hours. Bring safety hazards such as battery explosion

The power of the electric soldering iron used for soldering circuit boards is 16W~50W, and the temperature of the soldering iron tip is about 250°C. It works immediately when it is powered on. People often forget to unplug the plug after use, which brings great safety hazards.

[0004] In some areas where there are frequent power outages, the electrical appliances do not turn off the power after the power outage. Once the power comes in, they will power on and work by themselves, resulting in empty power consumption, shortened equipment life, and even major accidents such as electric shock and fire.
