Abstract
A kind of bus device of low-voltage distribution system, it includes low-voltage circuit breaker, switch bracket, binding post, bus, bus support, bus structure, contact, described low-voltage circuit breaker is fixed by switch bracket, binding post one end is connected by screw with low-voltage circuit breaker, the other end is connected to contact, the contact is connected with bus, and bus is fixed outside low-voltage circuit breaker by bus structure.Described bus using circular hollow tubular line.Described contact and bus contact site are semi arch structure.Bus uses tubular bus, and advantage is electric field, homogeneous current distribution, and dynamic stability is good.Bus material is preferably saved, and is easily achieved the standardized production of whole system；Contact is arc, and contact area is big, and resistance is small, and switch bracket is directly installed on tubular bus, without branch bus, greatly reduces copper material usage amount.
Description
Technical field
The present invention relates to power system low pressure electrical power trans mission/distribution system field, a kind of bus of low-voltage distribution system is specifically related to
Device.
Background technology
The generally rectangular cross-section bus of bus of conventional low-voltage distribution system, is divided into main bus-bar and branch bus again.Branch bus will
Low tension switch connects with main bus-bar.Its shortcoming is that space-consuming is big, and busbar usage amount is big, is taken during the processing installation fee of busbar
Work, maintenance not easy to install, cost are high.
Low-voltage drawer cabinet（Such as MNS, GCS, GCK）Use and rectangular bus bar, its advantage are that the replacing of drawer is convenient
Fast；Shortcoming is the increase in drawer, guide rail, connector etc., cost is high, volume is big, busbar usage amount is big, not easy heat radiation,
Fault rate is high.
Similar to Vinal's bus distribution system using I-shaped（Low current）Or " king " font（High current）
Bus, its shortcoming are：The electric current distribution of bus is uneven, thus the current-carrying capacity of copper busbar is not fully utilized, and causes copper
Material wastes；Such a bus Electric Field Distribution is uneven, unfavorable to the insulating properties of distribution system；Bus adaption device and bus contact area
Small, contact resistance is big, easily heating, and installation strength, insulating properties to whole system leave potential safety hazard.And such system ratio
Both above cost is higher.
The content of the invention
For the above situation, to overcome prior art defect, the purpose of the present invention is just to provide one low-voltage distribution system
Bus device, can effectively solve that existing product volume is big, it is high to waste copper material, cost, Electric Field Distribution is uneven, safeguards that inconvenience etc. is asked
Topic.
The technical scheme is that：A kind of bus device of low-voltage distribution system, it includes low-voltage circuit breaker, switch branch
Frame, binding post, bus, bus support, bus structure, contact, described low-voltage circuit breaker are fixed by switch bracket, binding post
One end is connected by screw with low-voltage circuit breaker, and the other end is connected to contact, and the contact is connected with bus, and bus breaks in low pressure
Road device is outer to be fixed by bus structure.
Preferably, described bus has three, has been respectively coupled contact outside every bus, has passed through between described contact
Winding displacement is connected, and is connected on binding post, and bus is fixed by bus support phase each other in low-voltage circuit breaker.
Preferably, described bus using circular hollow tubular line.
Preferably, described contact and bus contact site are semi arch structure.
Preferably, described bus support forms for epoxy resin pressure pouring.
The beneficial effects of the present invention are：1）Bus uses tubular bus, and advantage is electric field, homogeneous current distribution, is moved
Stability is good.In the case where not changing external diameter, only need to change wall thickness can change its current-carrying capacity, preferably save bus material
Material, and it is easily achieved the standardized production of whole system；2）The contact contacted on switch bracket with tubular bus is arc, contact
Area is big, and resistance is small；3）Distribution components can be installed on bus both sides, distribution system volume is reduced by about 50%, bus usage amount
Reduce 50%；4）Switch bracket is directly installed on tubular bus, without branch bus, greatly reduces copper material usage amount；5）It is applicable
It is wide, box-type substation, low-tension switch cabinet, low-tension distribution box etc. can be widely used in.
