Surge protector of the present invention; its shell, box body, slide block and moving block aerogenesis insulating material or not aerogenesis insulating material making; preferably make of aerogenesis insulating material; because the gas that aerogenesis insulating material produces cools electric arc on the one hand; enhance the air-blowing effect to electric arc on the other hand, the movement velocity of electric arc to arc control device gas outlet can be accelerated.Aerogenesis insulating material can select polyformaldehyde or nylon, melamine.
The operation principle of surge protector of the present invention:
Surge protector is through to work long hours or after repeat impact, overvoltage protection element (piezo-resistance) is deterioration gradually, temperature raises gradually, or there is especially big overload current to pass through, the temperature of overvoltage protection element (piezo-resistance) is caused to raise fast, when in second pin and release unit of overvoltage protection element, the temperature of metal clips weld reaches fusing or the melt temperature of solder, second pin of described metal clips and overvoltage protection element is disconnected from each other, relieve the active force that moving block in arc-control device is applied and the active force that stage clip in release unit is applied, thus the second limited wall direction arranged on box body under the elastic restoring force effect that the moving block in arc-control device produces at torsion spring is rotated, with the first limited wall direction motion that metal clips is set on box body under the elastic restoring force effect that slide block in release unit produces at stage clip, along with the rotation of moving block, metal clips after separately and overvoltage protection element second pin are carried out electrical isolation, both the electric arc that metal clips and the separation process of overvoltage protection element pin produce was cooled simultaneously, again the Shock-Motion backward that described electric arc produces is reflected, because reflected wave is consistent with the direction that electric arc moves towards arc control device gas outlet, electric arc is discharged from described gas outlet as early as possible, elongates.When moving block turns to the second limited wall place set on box body, the second pin of overvoltage protection element covers by the arcing chamber that moving block is arranged; Along with moving upward of slide block; the distance of metal clips and overvoltage protection element second pin constantly increases; when slide block drives metal clips to move to the first limited wall place set on box body, complete the electrical separation of metal clips and overvoltage protection element second pin.
The present invention has following beneficial effect:
1, the structure of the arc-control device in surge protector of the present invention makes it have the function extinguishing hard arc, release unit in surge protector of the present invention can make metal clips leave the second pin of overvoltage protection element fast, complete the quick electrical separation of metal clips and overvoltage protection element second pin, thus release unit is separated with circuit or device security when with the combination of arc-control device, ensure that surge protector breaks down, solve surge protector and be applied to the technical barrier that the thermally-stabilised disengaging of small area analysis in ac and dc systems and big current overload depart from, especially the alternating current circuit of higher system voltage and larger short circuit current or equipment (such as wind power plant) and higher system voltage and compared with the DC circuit of small short-circuit current or equipment (such as photovoltaic power generation equipment) application in there is very high fail safe.
2, experiment shows; when slide block drives metal clips to move to the first limited wall place set on box body; complete metal clips and overvoltage element second pin electrically separated after; namely surge protector departs from AC-DC Circuit or equipment completely; when applying maximum continuous operating voltage at its two ends; do not have and flow through more than the electric current of 0.5mA, thus fail safe improves.
3, owing to being provided with indicating device in surge protector of the present invention; thus the state residing for convenient operation personnel control overvoltage protection element; after overvoltage protection element breaks down, energy Timeliness coverage and replacing, guarantee the safety of protected circuit or equipment.
