Abstract
A lightning arrester for the communication lines of computer, fascimile equipment and telephone is disclosed. Two communication lines connected with telephone are introduced to its two lead-in terminals and connected with two ends of discharge tube, whose middle point is connected to the ground. Two lead-in terminals are serially connected with two fine fuses and then to two output connected to communication equipment. When lightning stroke occurs, strong current is led to the ground while the fuses are broken.
Description
The present invention relates to the communication line lightning arrester, the communication line lightning arrester of particularly a kind of computer, facsimile machine, telephone set.
At present, the user side of the communication line of the telephone set system that computer, facsimile machine, telephone set are shared is not equipped with lightning arrester basically, like this, and in when, suddenly thunderbolt taking place, tend to burn out computer, facsimile machine, the telephone set of user side, even can cause life danger.
The objective of the invention is to develop a kind of computer, facsimile machine, telephone set communication line lightning arrester, be installed in user side, if be struck by lightning, lightning arrester can be introduced heavy current underground, protection electrical equipment and personal safety.
The object of the present invention is achieved like this: develop a lightning arrester, two leading-in ends of two end introducing lightning arresters of registering one's residence of external telephone set, two leading-in ends are connected with the two ends of discharge tube respectively, and the mid point of discharge tube is connected with ground wire.Two leading-in ends also are connected two outputs respectively respectively with behind two groups of fuse polyphones.Two outputs and the electrical equipment that uses communication line connect as computer, facsimile machine, telephone set etc.During normal the use; electric current in the communication line from the leading-in end of lightning arrester through fuse to output; by output electric current is imported into various electrical equipment; if it is the heavy current that thunderbolt produces takes place suddenly,, underground from the grounding electrode introducing of discharge tube mid point heavy current with the gas discharge in the discharge tube that leading-in end is connected; simultaneously; size fusible circuit, breaker, heavy current can not be passed through, thereby protects electrical equipment effectively, personal safety.
Because the present invention is installed in communication line, the heavy current that can effectively prevent hitting unexpected thunderbolt generation burns out the generation of electrical equipment, life threatening incident.
Accompanying drawing 1 is a circuit theory schematic diagram of the present invention; Accompanying drawing 2 is structural representations of the present invention.
In conjunction with the accompanying drawings and embodiments, further describe structure of the present invention: in lightning arrester shell [8] inside, two fuses [2] are arranged, an end of every fuse [2] is connected with the end of leading-in end [1] with discharge tube [5], the other end of every fuse [2] is connected with output [3].The grounding electrode of discharge tube [5] mid point is connected with earth connection [4].When thunderbolt produces in the heavy current; gas discharge in the discharge tube [5]; the leading-in end [1] and the mid point of discharge tube [5] are connected; heavy current is introduced underground from earth connection [4]; fuse [2] disconnects simultaneously; output [3] does not have electric current to pass through, and protection computer, facsimile machine, telephone set etc. use the electrical equipment of communicating circuit and user's safety.
Claims (1)
