Abstract
The invention discloses a kind of discharge tubes with the anti-short circuit of operating point, it is related to lightning protection discharge tube technical field, it includes electric discharge tube body, the electric discharge tube body includes ceramic tube and electrode, electrode described in two groups and ceramic tube enclosed package are combined into electric discharge tube body, the electrode interior is provided with several electronic powders, is provided with operating point on electrode described at least one set.One or several operating points are added on the electrode, when lasting high current passes through operating point, calorific value concentrates on operating point, so that operating point is breakdown, the inert gas and the gas exchanges outside cavity of discharge tube internal cavity, the operation voltage of discharge tube is higher, discharge tube failure, discharge tube only has the calorific value of very little at this time, will not element to surrounding and shell impact, also avoid discharge tube electrode melting itself and form the phenomenon of short circuit.
Description
Technical field
The present invention relates to a kind of discharge tubes with the anti-short circuit of operating point, belong to lightning protection discharge tube technical field.
Background technique
Discharge tube is using hermetically sealed, and by two or the metal electrode of several band gaps, inside is filled with inert gas composition
(such as Fig. 1).
When the voltage for being added to two electrode tips reaches discharge tube operation voltage, discharge tube just starts to discharge, and by high resistant shape
State becomes on state, and the voltage of two interpolars is usually that good guarantor can be played to late-class circuit between 15~30V at this time
Shield effect, often by the main element as lightning protection device.
Common discharge tube electrode discharge face be plane or toroidal design, it is whole when there is lasting high current to pass through discharge tube
A electrode plane or anchor ring participate in electric discharge so that discharge tube fever is serious, cause discharge tube surrounding component, shell burning or put
The electrode of fulgurite two end electrodes fusing even fusing itself sticks together, and forms discharge tube two end electrodes short circuit phenomenon, limits
The application of discharge tube in many occasions.
Summary of the invention
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of discharge tubes with the anti-short circuit of operating point.
A kind of gas-discharge tube of anti-short-circuit failure of the invention, it includes electric discharge tube body, the electric discharge tube body
Including ceramic tube and electrode, electrode described in two groups and ceramic tube enclosed package are combined into electric discharge tube body, in the electrode
Portion is provided with several electronic powders, is provided with operating point on electrode described at least one set.
Further, the quantity of the operating point on the electrode described at least one set is one or several.
Beneficial effects of the present invention: it is reasonable in design, adds one or several operating points on the electrode, and lasting is big
When electric current passes through operating point, calorific value is concentrated on operating point, so that operating point is breakdown, the indifferent gas of discharge tube internal cavity
Gas exchanges outside body and cavity, the operation voltage of discharge tube is higher, and discharge tube failure, and discharge tube only has the fever of very little at this time
Amount, will not element to surrounding and shell impact, also avoid discharge tube electrode melting itself and form the phenomenon of short circuit.

Specific embodiment:
Embodiment 1:
As shown in Fig. 2, the present embodiment uses following technical scheme: it includes electric discharge tube body, and the electric discharge tube body includes
Ceramic tube 1 and electrode 2, electrode 2 described in two groups and 1 enclosed package of ceramic tube are combined into electric discharge tube body, in the electrode 2
Portion is provided with several electronic powders 3, wherein being provided with operating point 4 on electrode 2 described in one group.
Wherein, the quantity of the operating point 4 on electrode 2 described in the group is one.
Embodiment 2:
As shown in figure 3, the present embodiment uses following technical scheme: it includes electric discharge tube body, and the electric discharge tube body includes
Ceramic tube 1 and electrode 2, electrode 2 described in two groups and 1 enclosed package of ceramic tube are combined into electric discharge tube body, in the electrode 2
Portion is provided with several electronic powders 3, wherein being provided with operating point 4 on electrode 2 described in two groups.
Wherein, the quantity of the operating point 4 on electrode 2 described in two groups is one.
Embodiment 3:
As shown in figure 4, the present embodiment difference from example 1 is that: the quantity of the operating point on the group electrode 2
It is two.
Embodiment 4:
As shown in figure 5, the present embodiment and embodiment 2 the difference is that: operating point on wherein electrode 2 described in two groups
Quantity is two.
The working principle of the invention: when discharge tube inter-electrode voltage is greater than discharge tube operation voltage, the movement of discharge tube interpolar,
Since distance is smaller compared with electrode plane between operating point, lasting high current can be concentrated on operating point by operating point, calorific value,
So that operating point is breakdown, the inert gas and the gas exchanges outside cavity of internal cavity, the operation voltage of discharge tube is higher, puts
Fulgurite failure, discharge tube only has the calorific value of very little at this time, will not element to surrounding and shell impact, also avoid discharging
Electrode melting itself is managed, short circuit phenomenon is formed.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
