Abstract
A kind of connected mode of inlet wire copper bar, including breaker body, described breaker body is installed on base, inlet wire copper bar it is fixed with on described breaker body, described inlet wire copper bar embeds the front side suitable for reading of breaker body, the lower end of inlet wire copper bar is fixed by inlet wire bolt group, and described inlet wire bolt group embeds the inside of breaker body.The present invention is safe and reliable, easy to maintenance, has stopped electrical safety hidden danger.
Description
Technical field
The present invention relates to the connected mode of copper bar, particularly relate to the connected mode of a kind of low-voltage drawer cabinet inlet wire copper bar.
Background technology
The overlap joint of copper bar and fixing, the current-carrying capacity of one use to be met requires (selection of copper bar specification size is wanted rationally), (faying surface to meet the requirement of overlap joint area in requirement that standard specifies that two want faying surface to meet, the i.e. selection of bolt group is wanted rationally, guarantor unit's pressure), three want the overlap joint fixed structure of copper bar rationally, to meet dynamic and thermal stability to installation strength requirement.If the configuration process structure complexity of copper bar is unreasonable, the waste of copper bar can be caused, fixing to meet support strength of support insulators to be increased, meet the requirement of dynamic and thermal stability；Overlap joint is excessively simple or fixed insulation part uses unreasonable, and intensity deficiency is fixed in the installation that will result in copper bar, can not meet the requirement of dynamic and thermal stability, and be short-circuited accident.
Fig. 1 is the connected mode of existing GCK formula low-voltage drawer cabinet inlet wire copper bar, for back connection of circuit breaker, breaker body 1 is located on base 2, inlet wire copper bar 3 is installed on upper end on rear side of base 2, under this Connection Mode, it is necessary for increasing a connecting bolt 4(mono-male between breaker body 1 and the inlet wire copper bar 3 in cabinet female).This connecting bolt 4 is long-term under the high temperature conditions, easily oxidation, cause loose contact and serious vicious cycle of generating heat, the inlet wire binding post phase or the three-phase that eventually cause breaker body 1 burn out, there is great electrical safety hidden danger, and the inlet wire binding post of breaker body 1 once burns out, it is necessary to could overhaul after breaker body 1 place bus is had a power failure, expand power failure range during maintenance, bring strong influence to production.
Summary of the invention
The technical problem to be solved is, overcomes the drawbacks described above that prior art exists, it is provided that a kind of safe and reliable, easy to maintenance, stops the connected mode of the inlet wire copper bar of electrical safety hidden danger.
The technical solution adopted for the present invention to solve the technical problems is: the connected mode of a kind of inlet wire copper bar, including breaker body, described breaker body is installed on base, inlet wire copper bar it is fixed with on described breaker body, described inlet wire copper bar embeds the front side suitable for reading of breaker body, the lower end of inlet wire copper bar is fixed by inlet wire bolt group, and described inlet wire bolt group embeds the inside of breaker body.
Further, described inlet wire copper bar is three-phase copper bar.
Further, described breaker body upper end is provided with the bolt hole suitable with inlet wire bolt group.
Further, described inlet wire bolt group is made up of inlet wire binding post bolt and nut.
Further, the centre of described breaker body is provided with close/open machine.
Further, the downside of described breaker body is provided with the outlet binding post symmetrical with inlet wire binding post bolt.
The present invention compared with prior art has a characteristic that on front side of chopper and fixes copper bar, and inlet wire bolt group embeds circuit breaker internal, will the wire leading method of chopper by wiring before wiring changes plate into after plate, avoid because connecting bolt loose contact, heating effectively cause the fault that chopper inlet wire binding post damages, reduce electrical repair amount, ensure that the seriality of production, reduce cost, stop electrical safety hidden danger.
Accompanying drawing explanation
Fig. 1 is front view and the side view of existing inlet wire copper bar connected mode；
Fig. 2 is front view and the side view of the present embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, a kind of connected mode of inlet wire copper bar, including breaker body 1, breaker body 1 is installed on base 2, and breaker body 1 is fixed with inlet wire copper bar 3, and inlet wire copper bar 3 is three-phase copper bar, inlet wire copper bar 3 embeds the front side suitable for reading of breaker body 1, the lower end of inlet wire copper bar 3 is fixed by inlet wire bolt group, and it is internal that inlet wire bolt group embeds breaker body 1, and inlet wire bolt group is made up of inlet wire binding post bolt 5 and nut 6.
Breaker body 1 upper end of the present embodiment is provided with the bolt hole 7 suitable with inlet wire bolt group；The centre of breaker body 1 is provided with close/open machine 8, for separating brake and the combined floodgate of breaker body 1；The downside of breaker body 1 is provided with the outlet binding post 9 symmetrical with inlet wire binding post bolt 5, and outlet binding post 9 is for fixing the three-phase copper bar (not shown) of breaker body 1 end opening.
Inlet wire copper bar 3 embeds the front side suitable for reading of breaker body 1, the lower end of inlet wire copper bar 3 is fixed by inlet wire bolt group, it is internal that inlet wire bolt group embeds breaker body 1, form inlet wire before breaker plate, with shown in Fig. 1, inlet wire copper bar 3 is located at upper end on rear side of base 2, and wiring is compared after passing, by connecting bolt 4, the plate that breaker body 1 is fixed with base 2, avoid the frequent grafting because of connecting bolt 4, the shortcomings such as hot conditions is oxidizable cause loose contact, heating is serious, in turn result in the fault that chopper inlet wire binding post damages, reduce electrical repair amount, reduce cost, stop electrical safety hidden danger.
Claims (4)
1. the connected mode of an inlet wire copper bar, including breaker body, described breaker body is installed on base, inlet wire copper bar it is fixed with on described breaker body, it is characterized in that, described inlet wire copper bar embeds the front side suitable for reading of breaker body, and the lower end of inlet wire copper bar is fixed by inlet wire bolt group, and described inlet wire bolt group embeds the inside of breaker body；Described breaker body upper end is provided with the bolt hole suitable with inlet wire bolt group, and described inlet wire bolt group is made up of inlet wire binding post bolt and nut.
