Description
Technical field
The utility model belongs to power equipment interconnection technique field, is specifically related to a kind of switch cubicle adaptive electro connector.
Background technology
The one-time contact electric connection structure of switch cubicle is a significant points in switch cubicle design, the manufacturing, and main use is exactly Mume flower contact, watchband contact, duck-beak type contact in present mesolow switch cubicle industry.Because there is not better electric connection structure to occur, so shortcomings such as interior some heatings for existing electric connection structure of industry are severe, contact instability are compelled to accept.
The Mume flower contact fault of construction of mainly using in the industry now:
1, the maximum characteristics of Mume flower contact are contact quantity relative fixed, and total contact point is less relatively, and only can satisfy the requirement of different ampacitys through the quantity that increases or reduce contact chip.Because can each contact all will be born bigger through-flow thereby each contact and guarantee safe and reliable very greatly to the whole performance impact of contact, for example the use sheet number for the Mume flower contact standard of 1250A is 30.Require average every group need bear the long-term work electric current of about 84A and, account for total through-flow 6.8% greater than the 1666A/3 short circuit current of second.The whole performance of contact depends on the state of each sheet contact, needs each contact all will well contact and guarantees.But it is very difficult effectively controlling these baroque parts from each links such as material, manufacturing, assembling, scenes.If the contact of any a slice contact wherein goes wrong, the local heating up in this place makes the temperature of adjacent contact raise to produce a series of chain reactions further to worsen contact condition finally to cause contact to be lost efficacy very soon thereupon.
2, the Mume flower contact structure is little because of elastic force part volume; Elastic force changes greatly with condition of heat treatment and accumulation timeliness thereof; Bigger in similar annealed condition down spring forfeiture, when the switch starting the arc, very easily there are some inestimable conditions of heat treatment to occur; In 20 years maintenance cycles, whether can keep the designing requirement of original contact pressure, elastic force under what condition, can lose, when can make the pressure of contact to cause contact to lose efficacy and all be difficult to confirm less than design pressure.
3, the Mume flower contact structure can only guarantee the through-current capability of whole contact by increase and decrease contact quantity.The relative position of numerous contacts provides spacing by the geomery of middle part draw-in groove; Each draw-in groove all leaves certain surplus makes contact keep free relatively and adjustment nargin; But; The stressing conditions that influences each contact that receives conditioned disjunction precision such as design, processing and assembling can not be consistent, must make the burden of the heavier contacts of burden of some of them contact lighter.Yet the nargin of each contact through-current capability is all little, and the contact oxidation phenomenon can be more serious, causes vicious circle, and whole contact was lost efficacy, and causes ill effect, and this phenomenon danger in big current circuit is higher.
4, holddown spring is a key component wherein in the Mume flower contact structure, and its quality directly influences the performance of contact.Because the structural limitations of quincunx contact, what it adopted generally is the arc and small size helical spring of monofilament, and its performance very easily receives the interference of factors such as material, process conditions, power poor stability.
