Abstract

The invention discloses a surge protector of a telephone network system. The surge protector comprises a first wire, a second wire and an earth wire; a gas discharge tube circuit, an inductive circuit an a diode circuit are successively arranged from the input end to the output end of the protector, wherein the gas discharge tube circuit is a gas discharge tube connected between the first wire and the second wire, the gas discharge tube is connected with the earth wire, and the inductive circuit is two inductors which are separately in serial connection in the first wire and the second wire between the gas discharge tube circuit and the diode circuit. As the invention adopts the technical scheme, the telephone network system can be reliably protected from damages of the lightning stroke and surging current; and the surge protector has simple structure, low cost and convenient use.

Description

technical field [0001] The invention relates to a surge protector. Background technique [0002] Surge voltage will cause great harm to electrical appliances, so a surge protection device must be installed. The surge protection device used in the existing telephone network system has complex structure, high cost and inconvenient use. Therefore, it is necessary to develop a novel telephone network system surge protector to overcome the above-mentioned defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a telephone network system surge protector with simple structure, low cost, high reliability and convenient use. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: the surge protector for the telephone network system includes a first line, a second line and a ground wire, and is characterized in that: the protector is sequentially pr...
