Abstract
The utility model relates to a soft connecting line of a vacuum circuit breaker of a locomotive. The soft connecting line uses 0.1 mm stamping formed red copper sheets as a conductive main body with two ends crimped with binding posts, forming a soft connecting line with parallel two ends. The soft connecting line main body is formed by stacking copper sheets. The copper sheets are stamped as structure with specific shape. Because of stacking stamping formed members, the soft connecting line of a vacuum circuit breaker of a locomotive has characteristics of good integral performance, and dispersing and fracturing resistance. U-shaped structure enables parallel two binding posts to coincide with required motion trail, preventing the soft connecting line from colliding with other objects, prolonging mechanical life and increasing security. The soft connecting line is suitable for cases sustaining frequent motion of a high-speed locomotive.
Description
Technical field
The utility model relates to a kind of soft on line, the soft on line of particularly a kind of locomotive vacuum circuit-breaker.
Technical background
At present, the inner soft on line of the electric locomotive vacuum circuit-breaker that moves on the railway all adopts litzendraht wire to make, and its state is random big during motion; Often take place easily and other local collisions; Producing discharge in the high pressure effect, secondly is that litzendraht wire is to be formed by many tiny metal wire knitted, is easy to generate local fracture; Under the effect of long-time big electric current, cause the on line scaling loss easily, cause the locomotive trouble of shutdown.Therefore with litzendraht wire as the soft on line of locomotive vacuum circuit-breaker, cost is high, it is big to consume, maintenance frequently, inefficiency.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, aims to provide the soft on line of a kind of locomotive vacuum circuit-breaker safe and reliable, not easy fracture, long service life.
The technical scheme of the utility model is: the soft on line of a kind of locomotive vacuum circuit-breaker; It is made up of the binding post of soft on line main body and two compactings; It is characterized in that the binding post of described first compacting and the binding post of second compacting are to be parastate, promptly two binding posts are to be parastate, and said soft on line main body is made up of the stack of 0.1mm copper sheet; This copper sheet upper end is up big and down small arc transition structure, and the lower end is a U type structure.Said soft on line main body is made up of 32 0.1mm copper sheet stacks.
The soft on line of this locomotive vacuum circuit-breaker is owing to adopt the stack of punch forming part to form, and overall performance is good, can not disperse, rupture; Adopt U type structure simultaneously; Two binding posts become parastate, conform to the movement locus that requires, and can not bump with other places; Make mechanical endurance and fail safe obtain arriving very much raising, be applicable to the frequent movement of express locomotive.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of the utility model;
Fig. 3 is the stamping parts copper sheet structural representation of the utility model main body.
Among the figure: 1-binding post, the soft on line main body of 2-, 3-binding post, 21-copper sheet.
Embodiment
Referring to above-mentioned accompanying drawing; The soft on line of a kind of locomotive vacuum circuit-breaker; The binding post 3 that the binding post 1 and second that it is suppressed by soft on line main body 2, first is suppressed is formed; It is characterized in that the binding post 1 of described first compacting and the binding post 3 of second compacting are to be parastate, promptly two binding posts are to be parastate; Said soft on line main body 2 is made up of 0.1mm copper sheet (21) stack, and this said copper sheet 21 adopts and strikes out a kind of given shape, and promptly copper sheet 21 upper ends are up big and down small arc transition structure, and the lower end is a U type structure.Soft on line main body (2) is made up of 32 0.1mm copper sheets (21) stack.
The soft on line of this locomotive vacuum circuit-breaker adopts stamping forming 0.1mm copper sheet as conductive bodies, and crimping binding post in two ends constitutes the soft on line that two ends become parastate; The copper sheet that its characteristics are to adopt moulding conducts electricity very well as conductive bodies, and periphery is smooth; Be difficult for producing discharge, and pre-molding, movement locus is regular; Frangible not; Can long-time tolerating high voltage, the impact of big electric current, stopped the burning phenomenon that causes because of the on line breakage, improved the global reliability of product.
Claims (2)
1. soft on line of locomotive vacuum circuit-breaker; It is made up of the binding post (1) of soft on line main body (2), first compacting and the binding post (3) of second compacting; It is characterized in that the binding post (1) of described first compacting and the binding post (3) of second compacting are to be parastate, promptly two binding posts are to be parastate; Said soft on line main body (2) is made up of 0.1mm copper sheet (21) stack, and this copper sheet (21) upper end is up big and down small arc transition structure, and the lower end is a U type structure.
2. the soft on line of a kind of locomotive vacuum circuit-breaker according to claim 1 is characterized in that said soft on line main body (2) is made up of 32 0.1mm copper sheets (21) stacks.
