Description
Technical field
The present invention relates to a kind of overvoltage protecting device, have the overvoltage protection of edge flashing under particularly a kind of vacuum environment.
Background technology
In recent years, along with the develop rapidly of information-based industry, in the system because the harm that atmospheric over-voltage and switching overvoltage cause has caused that people pay attention to greatly.As the spark switch that various electrode shapes are arranged of overvoltage protection element and device, existing a large amount of report.Wherein representational is that German phoenix contacts the clearance type overvoltage protecting device of limited company and the high-energy discharge pipe of French CITEL is the surge protector of core.The characteristics that the technology of Germany phoenix contact limited company relates to have two electrodes for this overvoltage protection element and device; form the spark gap of V-shape; when light a fire in the gap; produce electric arc between two electrodes; under the effect of the effect of electromagnetic force and heat, electric arc moves forward along V font spark gap.Its advantage is to bear bigger rush of current, and shortcoming is that operation voltage is higher, and the operation voltage less stable.Its improved mode is to have placed auxiliary ignition device between the corresponding end of electrode, can cause surface ignition.Its advantage is that auxiliary air flashover spark gap is compared with the air gap that only depends on air breakdown comparatively constant operation voltage is arranged; Shortcoming is a still less stable of its operation voltage.The high energy gas discharge tube of France CITEL be the involved characteristics of technology of the surge protector of core be with two electrode package in earthenware, in this earthenware, charge into rare gas.Generally with two or three in parallel uses of gas discharge tube.Its shortcoming is because the gas discharge tube of several parallel connections generally can not move when overvoltage takes place simultaneously, so this overvoltage protecting device through-current capability can not be very big.The overvoltage protecting device of Germany OBO has comparatively constant operation voltage, and its shortcoming is that insulation resistance is less, and particularly after the protection hydraulic test, insulation resistance descends bigger, and leakage current is big during long-term work, will influence the reliability of its work.The domestic research work that is used for the overvoltage protecting device of power-supply system is started late, and particularly the overvoltage protecting device research level of big discharge capacity is lower.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art; a kind of good, consistent discharge voltage that has is provided; withstand shocks the greatly ability of electric current, long useful life, and the subsequent current that power frequency supply produced had good inhibiting overvoltage protection.
For achieving the above object, the technical solution used in the present invention is: comprise housing, two parallel electrodes are encapsulated in the housing by flange, and the vacuum degree in the housing is 10
-4～10
1Pa, the face that electrode is relative is provided with the electrode contact of being made by the alloy conductive material, and the center of electrode contact offers the installing hole that flashover element is installed, and flashover element is arranged in the electrode contact by installing hole.
Electrode contact of the present invention is a planar structure, and the discharging gap between two electrode contacts is 0.3-2.5mm; Electrode contact is provided with the boss of a diameter less than the electrode contact diameter, and the discharging gap between two boss is 0.3-2.5mm; Electrode contact one end is provided with the concave station of a diameter less than the electrode contact diameter, on concave station, offer the installing hole that flashover element is installed, flashover element is arranged in the electrode contact by this installing hole, and the discharging gap between two electrode contacts is 0.3-2.5mm; One end face of electrode contact is provided with the concave station of a diameter less than the electrode contact diameter, the other end of electrode contact is the plane, on concave station and plane, offer the installing hole that flashover element is installed, flashover element is arranged in the electrode contact by this installing hole, and the discharging gap between two electrode contacts is 0.3-2.5mm; The end face of electrode contact is provided with the installing hole that flashover element is installed, flashover element is arranged in the electrode contact by this installing hole, 30-60 ° angle is fallen in the inboard of installing hole, 15-30 ° angle is fallen in two end face outsides of electrode contact, and the discharging gap between two electrode contacts is 0.3-2.5mm; Offering one or more than one width on the flashover element is 20-200 μ m, and the degree of depth is greater than the annular isolation groove of 0.5mm; Electrode contact is a copper-tungsten, chromiumcopper, stainless steel or graphite; Flashover element is the strontium titanates or the titanium acid titanate series of the high-dielectric coefficient of dielectric coefficient in hundreds of arrives several thousand scopes.
Because the present invention is provided with flashover bar in two parallel symmetry electrode contacts, and be encapsulated under the vacuum environment, when gap breakdown, the gap carries out the transition to arc discharge by field emission, so have good, consistent discharge voltage, withstand shocks the greatly ability of electric current, long useful life, and the subsequent current that power frequency supply produced had very good inhibitory action.
