Abstract

The invention relates to the power field, in particular to a TV power supply. A TV power completely turning-off system comprises a TV body, wherein a transformer is arranged in the TV body, a power leading-in end is arranged on the primary side of the transformer, and an equipment power supply end is arranged on the secondary side of the transformer. The TV power completely turning-off system further comprises a switch-on maintain switch system which can main the switch-on state automatically after switch-on, and the switch-on maintain switch system is located between the power leading-in end and the transformer and comprises a switch-on signal leading-in end used for inputting a switch-on signal. The TV power completely turning-off system further comprises an auxiliary power supply, wherein the auxiliary power supply is provided with an electric signal output end, the electric signal output end is connected with the switch-on signal leading-in end, and the auxiliary power supply is further provided with an electric signal output switch used for controlling electric signal output of the electric signal output end. According to the design, electric energy at the power leading-in end is transmitted to the equipment power supply end through the switch-on maintain switch system and then supplied to an electric device circuit or the transformer connected with the equipment power supply end.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a TV power supply. Background technique [0002] After the TV is turned off, it only cuts off the power supply from the secondary side of the transformer to the electrical equipment, and the primary side is not turned off, so there is still some energy consumption. After the TV is turned off, the power consumption is still 3 to 5 watts. [0003] The voltage on the primary side of the TV transformer is high, and there are some dangers if it is switched manually. If it is controlled by electronic control, it will not be able to be turned on because the power supply has been completely shut off, and the electronic control system that implements the control cannot be powered. Contents of the invention [0004] The object of the present invention is to provide a system for completely cutting off the TV power supply to solve the above problems. [0005] The technical problem solved b...
