Abstract
The invention discloses a cable branch box. The cable branch box comprises a casing, a box door, and an inlet wire bus, an outlet wire bus and a ground bus which are transversely arranged in the casing. The inlet wire bus is provided with inlet wire breakers, the outlet wire bus is provided with outlet wire breakers, and the inlet wire breakers are connected with the outlet wire breakers through a busbar; and the inlet wire breakers and the outlet wire breakers are tripolar breakers, and the busbar is a lamination busbar. According to the invention, through improving the structure, the inlet wire breakers and the outlet wire breakers are connected through the lamination busbar, wiring in the casing is reduced, the requirement for the stress of heat and electricity generated when a possible short circuit occurs in an operation process is met, and reliable and safe operation is guaranteed.
Description
Technical field
The present invention relates to distribution box technical field, be specifically related to a kind of cable branch box.
Background technology
Along with developing rapidly of power industry modernization, the comprehensive startup of electric network reconstruction.Underground backbone cable, when certain distance needs to realize multiloop branch distribution, adopts cable branch box to be not only economy but also convenient and safe a kind of way as the important corollary equipment of distribution.
The structure of existing cable feeder pillar is simple, economical cheap, but volume is larger, clumsy, and casing is on-insulated; Circuit breaker adopts knife switch or isolating switch to control, to going out line user end unprotect.
Summary of the invention
Goal of the invention: for the deficiency of existing cable feeder pillar, the invention provides a kind of cable branch box, and structure is simple, and coefficient of safety is high.
Technical scheme: cable branch box of the present invention, comprise casing, chamber door and the lead-in line row of horizontally set, outlet row and ground row in casing, lead-in line row is provided with lead-in circuit breaker, and outlet row is provided with wire-outgoing breaker, and lead-in circuit breaker is connected with wire-outgoing breaker by busbar.
Described lead-in circuit breaker, wire-outgoing breaker are three-pole breaker, and each described lead-in circuit breaker is connected with three described wire-outgoing breakers, and described busbar is stack bus bar; Lead-in circuit breaker, wire-outgoing breaker and busbar are all with bolts.
Described stack bus bar comprises three layers of copper bar that lamination is arranged, and the centre distance between every layer of copper bar is equal with the center distance between described lead-in circuit breaker three-phase terminal.Described stack bus bar every layer copper bar is provided with an input connecting hole and three output connecting holes, the input connecting hole of every layer of copper bar is corresponding with the three-phase terminal of described lead-in circuit breaker output to be connected, and the output connecting hole of every layer of copper bar is corresponding with the non-inverting terminal of three wire-outgoing breaker inputs respectively to be connected.Setting between stack bus bar and lead-in circuit breaker, wire-outgoing breaker effectively reduces the wiring of box house.
Described lead-in circuit breaker is transparent mode isolation circuit breakers, and described wire-outgoing breaker is electronic type molded case circuit breaker; There is short-circuit protection, ground protection function, function such as isolation overload protection, under-voltage protection etc. can also be realized according to use Object Selection.
Described casing is welded by case lid, sidewall, base plate and bracing frame, and case lid edge extends sidewall, and sidewall is provided with louvre, and bracing frame is arranged on base plate lower end; Described chamber door one side link with described casing be connected, another side is fixed on described casing by hex bolts.Described casing adopts stainless steel to make.Casing adopts stainless steel welded rear pickling plastic-blasting, has the advantages such as dust-proof, fire prevention, corrosion-resistant, insulation; Chamber door upper and lower side adopts hexagonal anti-theft bolt to fix, and has anti-theft feature and anti-misoperation.
Beneficial effect: compared with prior art, advantage of the present invention: the present invention passes through modified node method, connected between lead-in circuit breaker and outlet short-circuiting device by stack bus bar, reduce the wiring in casing, meet the requirement of the stress of heat that the short-circuit conditions that likely occurs in the middle of running produces and electricity, ensure reliable safety; Box house is easy to expansion, and space availability ratio is large; Cabinet design takes into full account ventilation and heat, dust-proof, waterproof and antitheft, misoperation, uses safer.
