Abstract
The utility model discloses a new flexible connection structure for connecting moving conductor lever and conductor saddle inside the fixation poles vacuum breaker in the power distribution system. It includes several thick copper straps (1), lower copper block (2) and upper copper block (3). The thick copper strap (1) is formed with several long laminated thick straps. The lower copper block is the plane structure with regular polygon shape, whose top is equipped with tapered bore (4). The upper copper block is the plane structure with round shape, and its top has step holes (5), and its edge has a rectangle gap (6). Both sides of the thick copper strap (1) are fastened with the edge of the regular polygon and the gap of the rectangle respectively, and both are formed into the ''lantern'' shape by rounding the same center. Conductor saddle and moving conductor lever inside the fixation poles vacuum breaker are connected with bolts through tapered bore(4) and step holes(5). The connection, which is reliable, of small resistance, of low heating and of good heat dissipation, can meet the requirements of different current level and is flexible.
Description
Technical field
The utility model relates to the indoor high-voltage vacuum circuit breaker in a kind of electrical power distribution system, and special syndeton with the pole of electric current indoor high-voltage vacuum circuit breaker greatly is relevant.
Background technology
In the domestic electrical power distribution system, moving conductive rod mostly adopts by the direct-connected mode that is flexible coupling with the connection of conductive seat down in the pole solid sealed pole of vacuum circuit breaker of rated current 1250A and following current class.And rated current is at 1600A and when above, and along with the increase of electric current, cross-sectional area of conductor also will increase, and this moment, the wall scroll direct-connected mode that is flexible coupling can not realize linkage function.At present domestic most producer adopts the sliding contact ways of connecting in the connection of great-current fixed sealed pole moving conductive rod with conductive seat down, promptly in the conductive seat elasticity fingertip is being set down, and moving conductive rod is by contact with fingertip and slide relative realization linkage function.This mode contact resistance is big, and heating is serious, the heat radiation difficulty, and temperature rise, and elasticity fingertip performance is unreliable, and difficulty of processing is big.
The utility model content
The utility model be at moving conductive rod in the present great-current fixed sealed pole solid sealed pole of vacuum circuit breaker is connected difficulty with following conductive seat problem provide that a kind of contact resistance is little, heating less, the novel pole syndeton of good, flexible, the easy processing of radiating condition.
The technical solution of the utility model is: many strip thin copper belts are superimposed constitutes soft, very thick copper strips, is separately fixed at the two ends of several thick copper strips on two copper billets and surrounds " lantern " shape around same center.The copper billet of top is the circular sheet structure, and there is a circular hole centre, and some stepped holes are arranged on the circumferencial direction, is convenient to the connection with quiet support in the pole; Following copper billet is the regular polygon thin-slab structure, in the circular hole of band tapering is arranged, be convenient in pole connection with moving conductive rod.The thickness of copper strips and quantity are decided by the size of electric current, and the big more copper strips of electric current is just thick more.
The novel pole flexible connection structure that the utility model provides is connected by conductive seat and moving conductive rod under conical bore and the stepped hole use bolt realization pole, connect closely, reliably, contact resistance is little, heating is few, radiating condition is good, has greatly improved the electric conductivity and the reliability of operation of great-current fixed sealed pole.Compact conformation, processing is simple, and is safe and reliable, can satisfy the requirement of different current classes, and flexibility is strong.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model pole flexible connection structure;
Fig. 2 is the structural representation of following copper billet embodiment illustrated in fig. 1;
Fig. 3 is the structural representation of last copper billet embodiment illustrated in fig. 1;
Fig. 4 is the rigging position schematic diagram in pole embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, conductive seat 8, pole moving conductive rod under thick copper strips 2, time copper billet 3, last copper billet 4, conical bore 5, stepped hole 6, rectangle gap 7, the pole
As shown in the figure, the utility model pole flexible connection structure is gone up copper billet 3 by several thick copper strips 1, following copper billet 2 and one and is constituted.Thick copper strips 1 is formed by stacking by the soft tire thin copper belt of several strips, and the two ends of several thick copper strips 1 are fastened on down on copper billet 2 and the last copper billet 3 respectively and surround " lantern " shape around same center, and the quantity of thick copper strips 1 and thickness are decided by the size of electric current.Following copper billet 2 is the regular polygon slab construction, which is provided with conical bore 4, is used for the connection with pole moving conductive rod 8, and thick copper strips 1 is welded on the edge of regular polygon.Last copper billet 3 is circular slab construction, and rectangle gap 6 and stepped hole 5 are arranged on its edge, and rectangle gap 6 is used for the welding with thick copper strips 1, wears bolt when stepped hole 5 is used for 7 connections of conductive seat under the pole.This is flexible coupling being connected by conductive seat 7 and pole moving conductive rod 8 under conical bore 4 and the stepped hole 5 use bolts realization poles in solid sealed pole of vacuum circuit breaker.
