Furthermore, standby not only wastes energy, but also increases emissions.
In general, it is advocated that the best way to cut off standby power is to manually turn off the power switch or unplug the plug. However, users feel troublesome to turn off the power supply and unplug the socket, and often leave the electrical apparatus on standby.
For electrical equipment, particularly electrical components in the electrical equipment, the electrical equipment can be aged after long-term standby, the service life of the electrical equipment is shortened, and the electrical leakage and other risks exist in the process of electrifying. Although standby power is small, a large number of such devices are standby for a long period of time, resulting in a significant energy waste.
The world also notices the adverse effect caused by the resource waste, but no effective method is adopted to solve the adverse effect, and some measures, such as limiting standby power consumption of the electronic product to 1W or less, can reduce part of the waste, but complicate configuration of internal elements of the equipment and increase the cost of the product.
The sockets and control devices for individually cutting off standby power have been proposed and studied, but all use complex electronic control technology, and require complex control logic and systems, such as microcomputers, chips, transformers, relays, etc., so that the design and production costs of the devices are high, and users are reluctant to purchase such products at high price from the economical point of view.
