While various types of household appliances have solved many problems in people’s lives, appliances that have been on standby for a long time have consumed considerable amounts of electricity. According to the latest data from the National Energy Administration, in 2017, the electricity consumption of urban and rural residents in China was 869.5 billion kWh. 7.8% year-on-year growth. If the set-top boxes, induction cookers, washing machines and other appliances in the home are on standby for one day, they will consume about 0.45 kWh electricity, and more than 80 bucks in electricity fees in one year. If there are 100 million similar households, one day is wasted The power of up to 44 million kwh.
Cai Guoxiong, deputy chief engineer of the China Electric Power Academy, told reporters that electrical switches are usually divided into soft switches and hard switches. Soft switching appliances include induction cookers, washing machines, etc. They receive signals through the touch device, and are still in the standby state after the switch is turned off; Including the refrigerator, usually without the main switch, will always be in standby after plug in. Its power consumption is related to the frequency of use, and there is no inevitable relationship with the size of the electrical appliances, some appliances are in the home when they are on standby. ', need special attention.
The set-top box itself has little power, and its standby power consumption is very impressive. The data shows that the power of the set-top box in standby is about 15.2 watts, which is almost the same as the working power (15.4 watts), and much higher than the air conditioning (1.11 Wa), Microwave oven (0.32 watts), TV (0.21 watts) standby power. Although the screen is dark, but it also has some features to keep, such as the remote control wake-up function, indicator light display.
Devices that have remote control devices, such as televisions, air conditioners, etc., are equipped with sensor monitoring devices or remote control signal receiving devices. Without disconnecting the power supply, the remote control switch needs to be in standby mode in order to receive signals at any time. Many homes use air conditioners. The TV, after turning off the remote control, is still plugged in, leaving it in standby mode for a long time, and it consumes a lot of power.
Mobile phone chargers are also large household power consumers. Many people are accustomed to charging their mobile phones, or charging cables, and stealing a lot of power unconsciously. Too long charging time will accelerate battery aging and shorten the service life. Fire, explosion and other accidents.
Cai Guoxiong suggested that when the appliance is not in use, turning off the switch of the outlet or unplugging the power plug can effectively reduce standby 'stealing'.
