Small size high security of the present invention full mould protection surge protector, its shell, box body aerogenesis insulating material or not aerogenesis insulating material making, preferably make of aerogenesis insulating material.
The operation principle of small size high security of the present invention full mould protection surge protector:
Surge protector is through to work long hours or after repeat impact, voltage restricted type element group (piezo-resistance) in overvoltage protection element group is deterioration gradually, temperature raises gradually, or there is especially big overload current to pass through, the temperature of voltage restricted type element group (piezo-resistance) is caused to raise fast, when voltage restricted type element group pin with depart from the temperature of welding contact-making surface weld with metal clips in screening arc device reach fusing or the melt temperature of solder time, the welding contact-making surface of described metal clips and the pin of voltage restricted type element group disconnected from each other, relieve departing from and hiding the active force that in arc device, sliding part and spring apply, under the effect of spring restoring force, sliding part produces motion, when sliding part moves to set restraining position place, away from the pin after being separated with it under the effect of the auxiliary disengaging plate of welding contact-making surface in sliding part of metal clips, screening arc chamber in sliding part cover to weld with metal clips contact-making surface be separated after pin, the pin of the metal clips after separately and voltage restricted type element group is carried out electrical isolation.
When the voltage restricted type element group forming overvoltage protection element group is in normal condition, telecommunication equipment can arrange according to actual needs and be in closed or open-circuit condition, after the voltage restricted type element group of composition overvoltage protection element group is in abnormal condition and causes the welding contact-making surface of metal clips to be separated with the pin of voltage restricted type element group, depart from and hide the move under influence of the sliding part in arc device at spring restoring force, the support strip that sliding part is arranged promotes the swing arm on sensitive switch, the stop motion when sliding part moves to extreme position, the swing arm of sensitive switch is also pushed to required travel position simultaneously, sensitive switch is caused to carry out State Transferring, thus make remote signalling electrode 1, the state of 2 is changed, operating personnel are by remote signalling electrode 1, the State Transferring of 2, the state residing for overvoltage protection element group can be determined.
The present invention has following beneficial effect:
1, because disengaging of the present invention and screening arc device are after overvoltage protection element group is in abnormal condition and causes described welding contact-making surface to be separated with the pin of overvoltage protection element group; pin after the welding contact-making surface of metal clips can be made to be separated with it away from; again can chamber cover to weld with metal clips contact-making surface be separated after pin; thus this device can replace the release unit in patent CN201320177720.6 and the moving block in arc-control device; the device of this device of employing can not only be made to reduce volume, and can be cost-saving.
2, disengaging of the present invention is simple with screening arc apparatus structure, is convenient to processing and fabricating.
3, surge protector of the present invention departs to screening arc device owing to employing and has carried out corresponding improvement to supporting component; thus under smaller size smaller, achieve the full mould defencive function of L-N, L-PE, N-PE, its volume at least can accomplish about 1/5 of the full mould protection surge protector volume formed on patent CN201320177720.6 basis.
4, experiment shows; depart from and metal clips can be made to leave the pin of voltage restricted type element group fast with the sliding part hidden in arc device; when sliding part moves to restraining position; after completing the electrical separation of metal clips and voltage restricted type element group pin; surge protector i.e. complete and alternating current circuit, DC circuit or equipment departs from; when applying high-voltage large current at its two ends, there will not be secondary arcing phenomenon, thus surge protector of the present invention has high fail safe.
5, owing to being provided with telecommunication equipment in surge protector of the present invention; thus the state residing for convenient operation personnel control overvoltage protection element group; after overvoltage protection element group breaks down, energy Timeliness coverage and replacing, guarantee the safety of protected circuit or equipment.
