Abstract
The invention discloses a television power circuit. The television power circuit comprises a power input end, a surge protection circuit and a lightning protection circuit, which are sequentially connected, wherein the input end of the power input end is connected with an external power supply; and the output end of the lightning protection circuit is connected with an operating circuit of a television. By adoption of the circuit structure, the using safety of the television can be improved and the service life of the television is prolonged.
Description
Technical field
The present invention relates to household electrical appliance, particularly be used for the power circuit of television set.
Background technology
People's culture life has greatly been enriched in the appearance of television set; Yet television set in use also exists potential safety hazard; As at thunder and lightning weather,, then might endanger personal safety as well as the property safety because of inserting thunder and lightning if continue to use television set; So much human is selected the closing television machine at thunder and lightning weather, so just lost the use meaning of television set; In addition, the operating circuit of television set haves much room for improvement in use if during faults such as overcurrent, excess temperature, also can damage operating circuit.
Summary of the invention
The object of the invention is to provide a kind of television power circuit, and the safety in utilization that it can improve television set increases the service life.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of television power circuit comprises the power input, surge protection circuit and the lightning protection circuit that connect successively, and the input of power input connects external power supply, and the output of lightning protection circuit connects the operating circuit of television set.
Above-mentioned power circuit also comprises current foldback circuit and temperature protection circuit, and the input of said current foldback circuit connects the output of surge protection circuit, and the output of current foldback circuit connects the input of lightning protection circuit via temperature protection circuit.
After adopting such scheme; The present invention can avoid the influence of thunder and lightning weather to television set work through lightning protection circuit is set, and has both exempted the potential safety hazard of television set operating circuit; Also make people can watch television set, improve the service efficiency of television set at thunder and lightning weather; In addition, the present invention also increases surge protection, overcurrent protection and overheat protector, further improves the safety in utilization of television set, prolongs the useful life of television set.
Description of drawings
Fig. 1 is a structured flowchart of the present invention.
Embodiment
Below will combine accompanying drawing, technical scheme of the present invention and beneficial effect will be elaborated.
As shown in Figure 1; The present invention provides a kind of television power circuit; Comprise successively the power input, surge protection circuit, current foldback circuit, temperature protection circuit and the lightning protection circuit that connect, insert the operating circuit of television set by the output of lightning protection circuit, wherein; Power input connects external power supply, for the operating circuit of television set provides voltage; Surge protection circuit is used to prevent that television set from causing damage in the surge voltage of opening moment to components and parts; Current foldback circuit is used to prevent the damage of overcurrent fault to components and parts; Temperature protection circuit is used to then prevent that components and parts from influencing operate as normal because of working temperature is too high; Lightning protection circuit then can be avoided the influence of thunder and lightning weather to television set work, makes people also can watch television set at thunder and lightning weather, does not influence the use of television set.
Above embodiment is merely explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of on the technical scheme basis, being done all falls within the protection range of the present invention.
