Abstract
The utility model discloses a network line protection device, comprising temperature controllers, gas discharge tubes, current limiting resistors and TVS tubes, wherein lines are respectively connected with a ground line through the temperature controllers, the gas discharge tubes and the TVS tubes, and the current limiting resistors are connected in series between the gas discharge tubes and the TVS tubes. The network line protection device enables each line to be provided with a temperature controller, and the temperature controllers are combined with the gas discharge tubes, thereby greatly lowering a high temperature caused by a high line utilization rate, and avoiding the danger of line combustion.
Description
Technical field
The utility model relates to the protector field, especially relates to a kind of network line protector.
Background technology
At present; the network line protector mostly is to only have gas discharge tube; the TVS pipe, and only have the protection of 4 lines, in practical operation; the protection of circuit is unsound; temperature that can not control circuit, when high temperature occurring, can easy breaking out of fire etc. dangerous situation; and the utility model is provided with thermostat, can effectively solve problems.
The utility model content
The purpose of this utility model is to solve weak point of the prior art, and a kind of network line protector that can the control circuit temperature is provided.
Technical scheme: for achieving the above object, a kind of network line protector, it comprises thermostat, gas discharge tube, current-limiting resistance and TVS pipe, every circuit is respectively by described thermostat, described gas discharge tube and described TVS pipe earth connection, and described current-limiting resistance is connected between described gas discharge tube and the described TVS pipe.
Be provided with described thermostat on described every circuit.
Beneficial effect: the utility model is owing to all being provided with thermostat on every circuit, and the combination of thermostat and gas discharger can greatly reduce because the high temperature that trunks busy causes is avoided the danger of circuit burning.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, thermostat; 2, gas discharge tube; 3, current-limiting resistance; 4, TVS pipe.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
Shown in the figure, a kind of network line protector, it comprises thermostat 1, gas discharge tube 2, current-limiting resistance 3 and TVS pipe 4, every circuit is managed 4 earth connections by described thermostat 1, described gas discharge tube 2 and described TVS respectively, and described current-limiting resistance 3 is connected between described gas discharge tube 2 and the described TVS pipe 4.
The utility model is such implementation: be provided with described thermostat 1 on every circuit.
