Abstract
The invention discloses the syndeton of a kind of oil-filled transformer low pressure connector lug and conducting rod, comprise conducting rod and connector lug, radial through installing hole is provided with on the top of conducting rod, connector lug is provided with the wiring head bore suitable with installing hole, connector lug is sleeved on conducting rod, and by being arranged on the fastening bolt locking in installing hole and wiring head bore; Conducting rod is set with adjustment pad, and adjustment pad is positioned at below connector lug.This structure installment is reliable, is connected firmly, and cost savings raw material, meet the needs of production, adapted to the requirement of national policy.
Description
Technical field
The invention belongs to transformer manufacture technology, specifically the syndeton of a kind of oil-filled transformer low pressure connector lug and conducting rod.
Background technology
All the time, the low pressure connector lug of oil-filled transformer, conducting rod are all the structures continuing to use Shenyang Transformer Research Institute Uniting.Fig. 1 is the syndeton schematic diagram of traditional oils immersion transformer low voltage connector lug and conducting rod, and Fig. 2 is the vertical view of Fig. 1.During assembling, conducting rod 11 is installed below case lid 14, case lid top cover low voltage porcelain bottle 15, then compresses with plain cushion and clamp nut 16, plays the effect compressing and seal.Be inserted in connector lug 12, finally locked assembling with fastening bolt 13, retaining part is in the side of conducting rod.Conducting rod top and the bottom are polished rod, and middle part processes one section of screw thread and screws in for clamp nut.Along with the paces building economizing type, energy-efficient society are carried out by country, power transformer product design is also at past minute design, and the direction produced that becomes more meticulous strides forward.The shortcoming of this structure is: greatly, the length of conducting rod is long for clamp nut and the exposed span access location length of conducting rod; Because fastening bolt is in conducting rod side, need material many, cost is high.
Summary of the invention
In order to overcome prior art Problems existing, the object of this invention is to provide the syndeton of a kind of oil-filled transformer low pressure connector lug and conducting rod, this structure installment is reliable, is connected firmly; And due to without clamp nut, cost savings raw material, meet the needs of production, adapt to the requirement of national policy.
The object of the invention is to be achieved through the following technical solutions:
The syndeton of a kind of oil-filled transformer low pressure connector lug and conducting rod, comprise conducting rod and connector lug, it is characterized in that: be provided with radial through installing hole on the top of conducting rod, connector lug is provided with the wiring head bore suitable with installing hole, connector lug is sleeved on conducting rod, and by being arranged on the fastening bolt locking in installing hole and wiring head bore; Conducting rod is set with adjustment pad, and porcelain vase is pressed on case lid by adjustment pad by connector lug.
In the present invention, be processed with screw thread on the top of conducting rod, porcelain vase is pressed on case lid by screw thread by connector lug.Conducting rod is provided with two installing holes, and connector lug is sleeved on conducting rod by two fastening bolts.
In the present invention, connector lug removes the retaining part installing fastening bolt; Conducting rod top machining screw, bottom is polished rod; Another connector lug bores with conducting rod screw thread corresponding position the hole that two are worn clamp nut.
During assembling, conducting rod is installed below case lid, case lid top cover low voltage porcelain bottle, then adds adjustment plain cushion, is then threaded into connector lug until be arranged on case lid by porcelain vase consolidation from conducting rod, ensures sealing, finally penetrate fastening bolt and locked assembling.The effect of adjustment pad suitably increases and decreases to ensure that thrust enough seals when wiring head bore and conduction rod aperture are not overlapping, and the effect of fastening bolt is that locking connector lug follows thread pitch between conducting rod to ensure that contact is tight, reliable, to guarantee contact resistance.
The present invention decreases clamp nut and the exposed position of conducting rod about 20mm length on the basis of original structure, effectively reduces the length of conducting rod, and owing to saving clamp nut, reduce further cost; The retaining part that another former connector lug installs fastening bolt have also been obtained to be deleted.By comparing the conducting rod of different model specification and weighing of connector lug, average weight is reduced in about 28%.
The present invention installs reliably, is connected firmly, and cost savings raw material, meets the needs of production, has adapted to the requirement of national policy.
Accompanying drawing explanation
Fig. 1 is the syndeton schematic diagram of traditional oils immersion transformer low voltage connector lug and conducting rod.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is structural representation of the present invention.
Fig. 4 is the vertical view of Fig. 3.
Embodiment
A syndeton for oil-filled transformer low pressure connector lug and conducting rod, is shown in Fig. 3 and Fig. 4, and this syndeton comprises conducting rod 1 and connector lug 2.Conducting rod top machining screw, bottom is polished rod.Two radial through installing holes are provided with on the top of conducting rod, connector lug is provided with the wiring head bore suitable with installing hole, also the screw thread suitable with conducting rod top is provided with in connector lug, connector lug, and to be locked by two fastening bolts 3 be arranged in installing hole and wiring head bore by thread set on conducting rod; Connector lug eliminates the retaining part of traditional installation fastening bolt.Conducting rod is set with adjustment pad 6, and adjustment pad is positioned at below connector lug.Porcelain vase 5 is pressed on case lid 4 by adjustment pad by connector lug.
During assembling, conducting rod is installed below case lid, case lid top cover low voltage porcelain bottle, then adds adjustment plain cushion, is then threaded into connector lug until be arranged on case lid by porcelain vase consolidation from conducting rod, ensures sealing, finally penetrate fastening bolt and locked assembling.The effect of adjustment pad suitably increases and decreases to ensure that thrust enough seals when wiring head bore and conduction rod aperture are not overlapping, and the effect of fastening bolt is that locking connector lug follows thread pitch between conducting rod to ensure that contact is tight, reliable, to guarantee contact resistance.
