Description
Technical field
The present invention relates to a kind of surge protection device, particularly a kind of distribution system circuit and subsequent use protection module self-coming type surge protection device of communication system data transmission line employing of being used for.
Technical background
Surge protector is to be limited in the instantaneous overvoltage of scurrying into power line, signal transmssion line in the voltage range that equipment or system can bear, or powerful lightning current is let out the inflow place, the device that system is protected.Traditional surge protector; Inside has only a surge protection module; In use, when the surge protection module damage or after wearing out, like untimely replacing surge protection module; To make distribution line or communication data circuit be in no surge protection state, cause potential harm to equipment and personal safety.As: all be contained in power distribution cabinet inside the surge protector of distribution system; Cabinet need be opened and the operating state of surge protector could be found behind the door; When the surge protector body damages fault before the surge protection module that more renews again; The protection loop all is in off-state, and circuit is in the unprotect state.
In the communications industry 3G engineering; Electric power loop and signal data loop in a large amount of outdoor communication cabinets are all protected by surge protection device, because this communication cabinet infield all relatively disperses, the attendant is difficult in time watch the state of surge protector; And the service behaviour of surge protector is mainly pointed out through the change color of panel visual window; Show these three kinds of normal operating conditions, reserve operating state and malfunctions, and the function that does not have audio communication to report to the police, this warning through display panel ignored by administrative staff easily; Thereby, communication equipment is damaged.
In order to solve the problems of the technologies described above; The Chinese patent document discloses a kind of surge protection device, and the patent No. is " ZL200720121141.4 ", and patent name is " an overvoltage auto switching electric source surge protector "; This surge protector comprises control circuit module, first over-voltage protection module, at least one second over-voltage protection module; Said first, second over-voltage protection module connects through switch, after one group of over-voltage protection module breaks down, automatically switches to subsequent use over-voltage protection module; Through the switching between two groups of over-voltage protection modules, equipment is played the better protection effect; But the surge protector cost of this structure is higher, and realizes the switching of first, second over-voltage protection module through switch, and processing ease lost efficacy.
The content of invention
Technical problem to be solved by this invention is; Provide a kind of communication cabinet to use surge protection device; The surge protection device of this structure is through the automatic switchover between surge protection module and the stand-by protection module; Equipment is carried out better protection, improved the fail safe of communication cabinet greatly, and this surge protection device is simple in structure, with low cost.
In order to solve the problems of the technologies described above; A kind of communication cabinet of the present invention is used surge protection device; The stand-by protection module, the said surge protection module that comprise housing, surge protection module and be fixedly installed in the said housing are fixedly installed in the said housing through moving contact and fixed contact; Said moving contact is separately fixed at the end of incoming cables and the leading-out terminal of said surge protection module; Said fixed contact is separately fixed on the inlet wire post and outlet column of said housing, and said moving contact matches with corresponding said fixed contact respectively; Be provided with the module automatic bus between said surge protection module and the said stand-by protection module; Said module automatic bus comprises control contact, elastic device; Said elastic device comprises push rod, power spring; Said push rod one end withstands on the bottom surface of housing, and the other end withstands on the said surge protection module, and said power spring is enclosed within on the said push rod; The orthogonal one that is fixed into of said control contact and said push rod, said power spring one end withstands on the said control contact, and the other end withstands on the bottom surface of housing; Said surge protection module is provided with at least one compression spring, and said compression spring and said push rod laterally arrange, and said compression both ends of the spring withstands on respectively on the cross bar of said surge protection module and said housing.During operate as normal, after the connection of surge protection module puts in place, compress compression spring and push rod, carry out energy storage, and the contact of control contact and stand-by protection module and the outlet column of housing are broken off, make the stand-by protection module be in off-state through the surge protection module; When the surge protection module broke down, surge protection module moving contact and fixed contact contact-making surface melted, and the compression spring releases energy the surge protection module is ejected; After the surge protection module was ejected, push rod lost resistance, under the elastic force effect of power spring; The control contact is upspring, and the control contact is engaged with the contact of stand-by protection module and the contact of outlet column, and the stand-by protection device is inserted rapidly; Thereby, communication equipment is protected, prevent that communication equipment is damaged; Improved the fail safe of communication cabinet greatly; And realize the conversion of surge protection module and stand-by protection module, relatively simple for structure, with low cost and reliable through mechanical structure.
Above-mentioned a kind of communication cabinet is used surge protection device, and wherein, said moving contact is split type member, and said moving contact is made up of horizontal edge and vertical edge, the L-shaped one that is fixed into of said horizontal edge and said vertical edge, and said horizontal edge is processed by high hot melt material; Said fixed contact is the multi-groove type member, and the side of said fixed contact is provided with jack, and the periphery of said jack is provided with a rotating sheet; During connection, the horizontal edge of said moving contact hooks in the said jack, and with the pressing mutually of said rotating sheet.Because said moving contact horizontal edge processed by high hot melt material, can melt receiving under the rush of current situation of certain thunderbolt number of times and specific size, the surge protection module is ejected easily, and when changing as long as the surge protection module is inserted, change conveniently; The rotating sheet that forms through punching press is in addition guaranteed the contact-making surface of dynamic and static contact, make the surge protection module be connected into and out of terminal more reliable.
