Abstract
The invention discloses a mixed grounding device introduced from a cable for lightning interruption in a distributed base station. The mixed grounding device comprises a metal box body, a plurality of cable inlet holes and outlet holes formed in the wall of the box body, and an optical cable grounding device, a direct-current feed cable grounding device, a GPS (Global Positioning System) coaxial cable grounding device and a control line cable grounding device arranged in the box body. The mixed grounding device has the advantages that: problem of lightning protection of an optical cable, a direct-current feed cable, a GPS coaxial cable, a control line and the like entering into a distributed communication base station is solved. Cables are respectively connected with cable interfaces corresponding to a housing, and corresponding cables are led out from cable outlets and connected to corresponding equipment. Therefore, various cables are connected to the ground outdoors through the mixed grounding device so as to achieve the purpose of preventing lightning current from entering into a machine room through screening layers of the cables, metal members and the like.
Description
Technical field
The present invention relates to distributed communication base station lightning protection system, especially relate to the hybrid earthing device that distributed base station interruption thunder and lightning is introduced from cable.
Background technology
Distributed base station is generally provided with optical cable, DC feedback cable, GPS coaxial cable and control line.For avoiding the impact of thunder and lightning, current taked mode is: the lightning protection of optical cable adopts optical cable metal outer jacket and optical cable strengthening core ground connection on Shelf; The lightning protection of DC feedback cable adopts ground connection in the direct-current power distribution cabinet in DC feedback cable introducing machine room; The lightning protection of GPS coaxial cable adopts and GPS coaxial cable to be incorporated in equipment ground connection again; The lightning protection of control line adopts control line ground connection in calculator room equipment.Although aforesaid way also can protect calculator room equipment, play the effect of shielding lightning current, lightning current can not be avoided to introduce the problem of machine room by above-mentioned cable, and earth connection is too many, wiring is mixed and disorderly, brings many convenience to constructing operation.
Summary of the invention
The hybrid earthing device that the object of the invention is to provide a kind of distributed base station to interrupt thunder and lightning to be introduced from cable, both safe and reliable, saving cable, constructability operation again.
For achieving the above object, the present invention can take following technical proposals:
Distributed base station of the present invention interrupts the hybrid earthing device that thunder and lightning is introduced from cable, comprise metal case, be opened in multiple cables on described box wall into and out of hole, and be arranged on optical cable ground device, DC feedback cable earthing device, GPS coaxial cable earthing device in box body, control cable earthing device; Have metal ground plate at box body internal fixtion, the earth connection of described metal ground plate extends outside box body; Described optical cable ground device comprises the first metal fixing be arranged on for clamping optical cable metal sheath on metal ground plate, and for the second metal fixing of clamping optical cable metallic strength member; Described DC feedback cable earthing device comprises the metal fastener for connecting direct current cables metal screen layer, with into and out of binding post, metal fastener is electrically connected with metal ground plate, is describedly electrically connected into and out of binding post by wire, and turnover binding post and wire all insulate with metal case; Described GPS coaxial cable earthing device is made up of coaxial cable protector, and described coaxial cable protector earth terminal is electrically connected with metal ground plate; Described control cable earthing device is made up of control line protector, and described control line protector earth terminal is electrically connected with metal ground plate.
Multiple cables on described can body wall are respectively arranged with waterproof grommet into and out of Kong Chu.
The invention has the advantages that the lightning protection problem solving and enter the optical cable, DC feedback cable, GPS coaxial cable, control line etc. of distributed communication base station.The cable interface that these cables are corresponding with on described housing respectively connects, and draws from cable exit the equipment that respective cable is connected to correspondence.Therefore, above-mentioned all kinds of cable by the present invention outdoor ground connection, thus reach block lightning current enter machine room object by the screen, hardware etc. of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
