Description
Technical field
This utility model relates to a kind of joint-box, particularly a kind of ladder busbar formula joint-box, it is adaptable to 0.4
Kv cable.
Background technology
At present, urban power distribution network especially downtown area power load is stepped up, and low-voltage cable increases the most increasingly, low
Voltage cable junction box presents the mode of connection the most day by day complicated, the present situations such as looped network situation is numerous.This present situation brought many not
Profit factor, mainly show as following some:
1, connect in joint-box when drawing more than three low-voltage cables, need to install temporary connection plate additional, connect and draw extremely inconvenience,
Reduce work efficiency.
2, connect in joint-box when drawing more than three cables, make tour maintenance extremely complex.As there is low-voltage cable event
Barrier, is difficult to investigate in time fault, reduces power supply reliability.
3, connecing in joint-box when drawing more than three cables, the connecing of cable is drawn and removes work the danger such as maloperation easily occur
Danger, is unfavorable for the person and equipment safety.
Above unfavorable factor has had become as the technical barrier that this area is badly in need of solving.
Utility model content
This utility model is in order to solve above-mentioned technical problem, it is provided that a kind of ladder busbar formula joint-box, it is achieved low
Voltage cable connects draws safety, and it is clear to make an inspection tour, and wiring is neat, and management is in order.When breaking down, maintainer is facilitated to find out event in time
Barrier cable is rushed to repair, and can greatly improve work efficiency.
This utility model is achieved through the following technical solutions:
Ladder busbar formula joint-box, including casing, it is characterised in that be provided with copper bus-bar, low pressure in described casing exhausted
Edge and insulator block, described low tension insulator is arranged on the two ends of copper bus-bar, and copper bus-bar is provided with boring, is used for connecing and draws electricity
Cable-end, low tension insulator is connected with the insulator block being fixed in casing, and the side of casing is provided with chamber door, and chamber door is provided with handle
Hands.
Wherein, described copper bus-bar for be fixed on box house ecto-entad, the most successively by zero, A, B, C three-phase
Four single row of holes copper bus-bars of four-wire system step arrangement.
Wherein, at least provided with six borings on described copper bus-bar.
Wherein, described chamber door is that embedded side opens the door.
Wherein, the corner, the back side of described casing is provided with fixing hole, for being fixed on the wall by casing.
Wherein, described casing is without bottom surface, without the empty steel casing at the back side, connects for long cable section of ingoing line and draws.
Wherein, the quantity of described low tension insulator is eight.
Compared with prior art, the beneficial effects of the utility model are: can reach low-voltage cable and connect and draw safety, make an inspection tour clear
Clear, wiring is neat, manages orderly purpose；Maintainer can also be facilitated to find out failure cable in time enter when breaking down
Rob and repair.It is particularly well-suited to downtown area low-voltage cable looped network and connects use, be extremely easy to power system 0.4kV low-voltage cable and supply
Electric network is promoted.
