Background technology
Surge protector is commonly used in the electric wiring of family, office space, industrial site etc., for preventing the damage to electrical equipment of the instantaneous overvoltage overcurrent in circuit. When producing suddenly peak current or voltage because of extraneous interference in electric loop or communication line, surge protector can turn on shunting within the time of moment, thus avoiding surge to the infringement of other equipment in loop.
Surge protector common on the market is generally all made up of two parts of base and surge protection module, realizes plug-in and connect between surge protection module and base. Wherein, surge protection module includes varistor (MOV), it is possible to be used for shifting unnecessary voltage. But, after long-time use, varistor can become aging and easily generate heat, and may produce safety issue in use procedure. In order to prevent varistor overheated, tripping mechanism generally also can be set in surge protection module. Time when surge protection module is operated in high voltage, big electric current; internal components can produce significantly high heat moment; heat is transferred to tripping mechanism and by the low temperature melts soldering tin in tripping mechanism, and then tripping mechanism can separate with varistor under the pulling force effect of spring. Due to high-tension effect, the air gap after tripping mechanism separation can be produced electric arc by voltage breakdown. And the generation simultaneous high temperature of electric arc, it is possible to the damage of device can be caused, time serious, also affect the safety of lives and properties, therefore be badly in need of a kind of surge protection module with arc-control device and arc insulating apparatus and go to solve above-mentioned problem.

For achieving the above object, the technical solution of the utility model is specifically achieved in that a kind of surge protection module with arc-control device and arc insulating apparatus, including housing, varistor and tripping mechanism, described housing is respectively provided on two sides with first, second terminal, described varistor is located at housing back and has the second electrode extending to the first anterior electrode of housing and being connected with described second terminal, described tripping mechanism includes departing from bar, extension spring and dropout sheet, one end of described disengaging bar and housing hinge, the other end of described disengaging bar is connected with housing by extension spring, described dropout sheet is articulated with on housing, and fix with described first electrode welding, it is connected by wire between described dropout sheet and described the first terminal, the middle part of described disengaging bar is additionally provided with the projection being resisted against on described dropout sheet and promoting at high operating temperatures described dropout sheet with described first electrode separation, described projection is also extended with the holly strip being inserted between both after described dropout sheet and described first electrode separation, described housing is additionally provided with arc-chutes at the welding ends side-lower of described dropout sheet, in described arc-chutes, distribution has some arc quenching plates. dropout sheet described in this utility model and between described first electrode adopt eutectic welding tin welding.
The beneficial effects of the utility model are: pass through to arrange arc-chutes in surge protection module in the technical solution of the utility model and make tripping mechanism be dissipated by the effect of arc quenching plate in arc-chutes at the electric arc that moment of threading off produces; additionally; owing to the low temperature scolding tin between dropout sheet and electrode can at high temperature dissolve; low temperature scolding tin after dissolving can be driven by departing from bar and produce a large amount of electric arc between dropout sheet and the first electrode; therefore depart from the holly strip arranged on bar to play partition electric arc and prevent the produced arcing of scolding tin drippage, thus reaching the effect of arc.
The field ratio used due to surge protector is wide, for instance the DC high voltage that photovoltaic, wind-powered electricity generation use, and during disjunction, produced electric arc is difficult to extinguish, and in order to enable the more effective fire hazard preventing direct current arcing from causing, this utility model is further arranged to:
Described housing back is additionally provided with fuse, one end of described fuse is connected with the second terminal, the other end of described fuse is connected to guide card, and the head end of described guide card extends to housing front portion, and forms conducting with dropout sheet after dropout sheet and the first electrode separation. The setting of fuse, it is possible to avoid, reduce the formation of electric arc.
Loose contact when turning on the head end of guide card after separating in order to avoid dropout sheet, this utility model is further arranged to:
The head end of described guide card is in the shape of the letter V structure, and described housing front portion is provided with a projection, and described projection is provided with the projection inserting V-shaped head end.
For making the purpose of this utility model, technical scheme and advantage clearly, develop simultaneously embodiment referring to accompanying drawing, this utility model is described in further detail.
