Abstract
The invention relates to a surge protection system for a communication line. A circuit breaker is connected with an overload protection circuit in series, and a thermal sensor is connected with a control chip, therefore, when a surge appears in the communication line, even if the overload protection circuit can not realize real-time protection, the thermal sensor can send transient high heat temperature signals caused by overload to the control chip, so that the circuit breaker is cut off to play a role in the protection of electronic components in the communication line, and thus the consequence that the electronic components are burnt can be avoided.
Description
Technical field
The present invention relates to communication technical field, particularly a kind of surge protective system for communication line.
Background technology
The surge protection system that uses at communication line at present mainly still adopts the not high overload protecting circuit of precision that uses on the electric equipment to protect; And the common connection of communication line is to the very sensitive electronic component of current overload; If according to the surge protection system on the electric equipment, be prone to cause that overload is failed real-time guard and the consequence of burning electronic component.
Summary of the invention
The present invention provides a kind of surge protective system for communication line; Through the circuit breaker of connecting, add that heat sensor is connected with control chip, so when surge appears in communication line with overload protecting circuit; Both made the overload protecting circuit can't real-time guard; But through heat sensor the hot temperature signal of instantaneous height that overload causes is sent to control chip, just can cut off the effect that circuit breaker plays the electronic component of protection communication line, the consequence of having avoided electronic component to burn.
For realizing above-mentioned purpose, technical scheme of the present invention is:
A kind of surge protective system for communication line 1; Comprise the surge protection system 1 that has overload protecting circuit 2; In addition with heat sensor 3 of overload protecting circuit 2 parallel connections; Heat sensor 3 links to each other with control chip 4, the control end of control chip 4 be connected with the controlled end of the circuit breaker 5 of overload protecting circuit 2 series connection.
Through the circuit breaker 5 of connecting with overload protecting circuit 2; Add that heat sensor 3 is connected with control chip 4; So when surge appears in communication line, both made the overload protecting circuit 2 can't real-time guard, but the hot temperature signal of instantaneous height that overload causes had been sent to control chip 4 through heat sensor; Just can cut off the effect that circuit breaker 5 plays the electronic component of protection communication line, the consequence of having avoided electronic component to burn.
Description of drawings
Accompanying drawing is represented structural representation of the present invention.
Embodiment
Through accompanying drawing the present invention is further specified below:
Shown in accompanying drawing; A kind of surge protective system for communication line 1; Comprise the surge protection system 1 that has overload protecting circuit 2; With heat sensors 3 of overload protecting circuit 2 parallel connection, heat sensor 3 links to each other with control chip 4 in addition, and the control end of control chip 4 is connected with the controlled end of the circuit breaker 5 of connecting with overload protecting circuit 2.
Through the circuit breaker 5 of connecting with overload protecting circuit 2; Add that heat sensor 3 is connected with control chip 4; So when surge appears in communication line, both made the overload protecting circuit 2 can't real-time guard, but the hot temperature signal of instantaneous height that overload causes had been sent to control chip 4 through heat sensor; Just can cut off the effect that circuit breaker 5 plays the electronic component of protection communication line, the consequence of having avoided electronic component to burn.
