Abstract
The utility model discloses a multi-end balancing discharge tube which comprises a ceramic hollow cavity (1), line electrodes (4) and a ground electrode (3), wherein the line electrodes (4) and the ground electrode (3) are arranged in the cavity. The multi-end balancing discharge tube is characterized by comprising a plurality of line electrodes (4) and at least one transition electrode (2), wherein the transition electrode (2) is located between the line electrodes (4) and the ground electrode (3) so as to form a first discharge gap between the line electrodes (4) and the transition electrode (2) and form a second discharge gap between the transition electrode (2) and the ground electrode (3). The utility model is a multipath balancing gas discharge tube which has the advantages of simple wiring, strong ability of follow current interrupting and fast response.
Description
Technical field
The utility model relates to the overvoltage arrester parts of using gap, particularly a kind of gas discharge tube that can be used for the instantaneous overvoltage protection of various information systems.Especially refer to a kind of multiterminal balance discharge tube.
Background technology
At present in communication, traffic signal system, computer data processing system, video monitoring system and cable television system; For the infringement that the transient overvoltage of taking precautions against and avoid direct lightning strike, induction thunder to produce brings to system, lightning arrester normally is installed in these systems is solved.And as using main components and parts---the gas discharge tube of lightning arrester comparatively widely; Generally constitute, fill with inert gas in it by battery lead plate that upper and lower two blocks of metal materials are processed, cross sectional shape is " protruding " shape and the hollow cylinder body of processing by insulating material.Originally isolated discharge tube is with the demand of lightning protection in the transmission course of incompatibility multichannel, multi-thread signal, and the data line lightning arresting of 8 lines for example is if accomplish balance between the line line; Need 28 isolated discharge tubes; Not tight volume is big, and wiring is complicated, thereby makes the reliability of system greatly reduce.
Summary of the invention
To the shortcoming of prior art, the purpose of the utility model is to provide the fast gas discharge tube of multichannel balance, reaction speed that a kind of volume is little, wiring simple, the follow current interrupt ability is strong, promptly a kind of multiterminal balance discharge tube.
The utility model solves the technical scheme that its technical problem adopted: a kind of multiterminal balance discharge tube is provided, comprises line electrode and ground electrode in ceramic hollow cavity, the cavity, it is characterized in that; A plurality of line electrodes and at least one transition electrode are arranged, and said transition electrode is between line electrode 4 and the ground electrode 3, makes to form between line electrode and the transition electrode to form second discharging gap between first discharging gap, transition electrode and the ground electrode.
In use what outside line transition electrode need not to take over, and is promptly unsettled, can be used as the sucker of automatic chip mounting owing to cross the plated electrode plane simultaneously, aims at the paster application and the sucker of increase and saved isolated discharge tube.
The beneficial effect of the utility model is: volume is little, wiring is simple, the follow current interrupt ability is strong, multichannel balance, reaction speed are fast.Each breakdown process includes two basic identical discharging gaps of size, makes the puncture voltage of each line consistent; A plurality of line electrodes are owned same discharge cavity together, can eliminate the destruction that lateral voltage is brought between each line; Double gap increases aura/arc light pressure drop and is twice, and can improve breath arc ability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to describe.
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1 is that ceramic hollow cavity, 2 is that transition electrode, 3 is that ground electrode, 4 is line electrode.
Embodiment
Referring to accompanying drawing, a kind of multiterminal balance of the utility model discharge tube comprises line electrode 4 and ground electrode 3 in ceramic hollow cavity 1, the cavity, it is characterized in that; A plurality of line electrodes 4 and at least one transition electrode 2 are arranged, and said transition electrode 2 is between line electrode 4 and the ground electrode 3, makes to form between line electrode 4 and the transition electrode 2 to form second discharging gap between first discharging gap, transition electrode 2 and the ground electrode 3.
In the embodiment of the utility model, 4 line electrodes 4 and 1 ground electrode 3 are arranged.4 bindings form a blanket gas body cavity completely with line electrode with ground electrode 3 transition electrode 2 through ceramic hollow cavity 1.
In the embodiment of the utility model, adopt silver-copper brazing alloy the transition electrode sealing-in in metallized ceramic chamber one end, line electrode and ground electrode sealing-in at the other end.
