The utility model has disclosed the novel cable feeder pillar of function with ground, in casing, be provided with inlet wire cable and outlet cable, described inlet wire cable connects copper bus-bar through air switch, described outlet cable is provided with multichannel, connect copper bus-bar by outlet contact in the middle of double end disconnection switch with ground respectively, under described double end disconnection switch with ground, contact passes through ground connection.The utility model has the advantage of in safeguard protection; make feeder pillar possess earthing switch blade function; in feeder pillar, earth point is set up in outlet; and by being installed, plug-in strip is serially connected between low-pressure line-outgoing and ground connection; utilize the operation of this plug-in strip is realized to line maintenance state; eliminate the potential safety hazard of installing earth connection in feeder pillar, improved personnel's protectiveness, the fail safe of equipment on the one hand, impel on the other hand operation field ground connection simple to operate, quick, reliable.
Description
Technical field
The utility model relates to the technical field of low-voltage power supply, relates in particular to the low-voltage distribution apparatus in low-voltage power supply system.
Background technology
Tend to cause cable to use waste if long apart from the cable (Bundling conducting wire) that uses a lot of root small sizes in supply line, therefore in supply line, conventionally use the large cable outlet of trunk, then in approaching load, use feeder pillar main cable (Bundling conducting wire) to be divided into the cable (Bundling conducting wire) of some small sizes, and then access load.On a longer circuit, the length of cable (Bundling conducting wire) cannot meet circuit and require (the rule of thumb circuit more than 1000 meters), in order to ensure safety, so just must use cable joint or this cable connection box.
Feeder pillar has been responsible for electric energy conversion and has been distributed in low-voltage power supply system.Along with scientific and technological progress, the application of cable (Bundling conducting wire) feeder pillar is more and more wider.According to the development plan of power distribution network, in the time that the little independent load distribution of capacity is comparatively concentrated, can use feeder pillar to carry out branch to connect, be mainly that cable (Bundling conducting wire) is carried out to tap or switching.The development of its development and national economy, science and technology and living standards of the people is closely related.
Feeder pillar is widely used in open air at present, along with the progress of technology, the usage quantity of feeder pillar constantly increases, because feeder pillar back panel wiring is simple, also make the use problem of feeder pillar become increasingly conspicuous, such as, if when wherein branch road need to overhaul, need all branch roads all to accompany and stop, expanded power failure range, greatly affected rural power grids power supply reliability.In addition box house does not have safeguard protection facility, has Danger Electric shock risk.
Utility model content
Technical problem to be solved in the utility model is that realization is a kind of safe and reliable, facilitates the feeder pillar structure of later maintenance.
To achieve these goals, the technical solution adopted in the utility model is: the novel cable feeder pillar of function with ground, in casing, be provided with inlet wire cable and outlet cable, described inlet wire cable connects copper bus-bar through air switch, described outlet cable is provided with multichannel, connect copper bus-bar by double end disconnection switch with ground respectively, described double end disconnection switch with ground passes through ground connection.
Described double end disconnection switch with ground is provided with the error-preventing locking mechanism that prevents on-load drawing plug-in strip.
Described casing is provided with chamber door, and described chamber door is provided with door lock.
Described casing adopts stainless steel galvanized sheet punch welding to make.
The backboard of described box house is provided with the fixed leg of protrusion, on described fixed leg, is fixed with transparent plastic sheet by screw, and described air switch, copper bus-bar, double end disconnection switch with ground are all between backboard and transparent plastic sheet.
The utility model has the advantage of in safeguard protection; make feeder pillar possess earthing switch blade function; in feeder pillar, earth point is set up in outlet; and by being installed, plug-in strip is serially connected between low-pressure line-outgoing and ground connection; utilize the operation of this plug-in strip is realized to line maintenance state; eliminate the potential safety hazard of installing earth connection in feeder pillar, improved personnel's protectiveness, the fail safe of equipment on the one hand, impel on the other hand operation field ground connection simple to operate, quick, reliable.
Brief description of the drawings
Below the mark in content and figure that in the utility model specification, every width accompanying drawing is expressed is briefly described:
Fig. 1,2 is feeder pillar structural representation;
Mark in above-mentioned figure is: 1, inlet wire cable; 2, air switch; 3, copper bus-bar; 4, double end disconnection switch with ground; 5, outlet cable; 6, earth connection.
Embodiment
The utility model is a kind of cable (Bundling conducting wire) feeder pillar of function with ground, in casing, be provided with inlet wire cable 1 and outlet cable 5, general inlet wire cable 1 enters casing by casing top, outlet cable 5 is by bottom half outlet, outlet cable 5 has multichannel, be respectively customer power supply, the figure example of Fig. 1,2 Zhong Shi tri-tunnel outlet cables 5.
Casing preferably adopts stainless steel galvanized sheet punch welding to make, and casing has chamber door, and chamber door is provided with door lock, can avoid inoperative people to open feeder pillar.As Fig. 1, shown in 2, inlet wire cable 1 connects copper bus-bar 3 through air switch 2, copper bus-bar 3 is provided with three, every road outlet cable 5 is connected with the middle outlet contact of double end disconnection switch 4 with ground respectively, double end disconnection switch 4 with ground is provided with the error-preventing locking mechanism that prevents on-load drawing plug-in strip, its upper end contact connects copper bus-bar 3, lower end contact is by earth connection 6 ground connection, obvious cut-off point when double end disconnection switch 4 conducts with ground are overhauled, and improve line maintenance security reliability, and all the other branch roads stop without joining, dwindle power failure range, improve rural power grids power supply reliability.
For avoiding inoperative personnel to operate electric shock, the backboard of box house is provided with the fixed leg of protrusion, on fixed leg, be fixed with transparent plastic sheet by screw, air switch 2, copper bus-bar 3, double end disconnection switch 4 with ground be all positioned at backboard and transparent plastic sheet it, transparent plastic sheet is put the convenient internal components of observing, in the time that needs overhaul, conventionally screw out screw, can unload easily transparent plastic sheet, both easy to use, improve again security performance.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
