An anti-interference energy-saving socket

Abstract

The invention provides an anti-interference energy-saving socket, which includes a socket body having a main control jack and a secondary control jack, and an anti-interference module and an energy-saving module are arranged in the socket body; the energy-saving module is connected to the fire wire of the main control jack, It is used to monitor whether there is electricity on the main control jack; the anti-interference module is connected to the live wire, ground wire and neutral wire of the power supply, and is used to suppress the differential mode interference and common mode interference generated on the power line. The anti-interference and energy-saving socket of the invention can not only effectively suppress the interference on the power line, but also realize zero standby power consumption. By testing the anti-interference ability of the whole socket, the test result shows that the socket of the present invention meets the requirement of attenuation of 50dB in the frequency range of national standard 150kHz-30MHz.

Description

technical field [0001] The invention relates to a socket, in particular to an anti-interference and energy-saving socket. Background technique [0002] With the widespread popularization of electronic equipment, computers and household appliances, the problem of power supply noise interference has become increasingly prominent and has become a serious public hazard, especially transient noise interference, which has a fast rising speed, short duration, and high voltage amplitude. Microcomputers and digital circuits are prone to serious interference. According to statistics, 88.5% of the causes that seriously threaten the safe and reliable operation of electrical and electronic equipment come from electromagnetic interference in the power supply. Therefore, it is necessary to solve the problem of effectively suppressing power supply noise from interfering with electronic equipment, and at the same time preventing power supply noise from entering the AC power grid and interfe...

AI Technical Summary

Problems solved by technology

For household or office appliances, the suppression object of the common mode interference is mainly the common mode noise interference from the power grid, because the common mode noise interference will affect the systemization of the image and sound

At present, the electromagnetic interference suppression sockets on the market can reduce the electromagnetic interference on the power line, but they can only suppress the differential mode interference, but cannot suppress the common mode interference.

[0003] In addition, with the widespread use of household appliances and office appliances, coupled with the fact that people do not have the habit of turning off the power at any time when the appliances are not in use, the power wasted due to the standby of appliances is astonishing. Bad electricity consumption habits cause the waste of electricity due to electrical standby up to 1.2 billion kWh per year
