Abstract
The utility model discloses an oil-immersed transformer low-voltage terminal and conducting rod connecting structure. The connecting structure comprises a conducting rod and a terminal, a radial through mounting hole is formed in the upper portion of the conducting rod, a terminal hole matched with the mounting hole is formed in the terminal, the terminal sleeves the conducting rod, the terminal and the conducting rod are locked by fastening bolts arranged in the mounting hole and the terminal hole, and an adjustable gasket sleeves the conducting rod and is positioned below the terminal. The connecting structure is reliable to mount and firm in connection, raw materials are greatly saved, production requirements are met, and requirements of national policies are met.
Description
Technical field
The utility model 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 of continuing to use Shenyang Transformer Research Institute Uniting.Fig. 1 is the syndeton schematic diagram of traditional oil immersed type transformer low voltage connector lug and conducting rod, and Fig. 2 is the vertical view of Fig. 1.When assembling, conducting rod 11 is installed below case lid 14, case lid top cover low pressure porcelain vase 15, then compress with plain cushion and clamp nut 16, play the effect that compresses and seal.Be inserted in connector lug 12, finally locked assembling with fastening bolt 13, retaining part is in a side of conducting rod.Conducting rod top and the bottom are polished rod, and middle part one section of screw thread of processing screws in for clamp nut.Along with the paces of construction economizing type, energy-efficient society are carried out by country, power transformer product design is also in the past design that becomes more meticulous, and the direction of producing that becomes more meticulous strides forward.The shortcoming of this structure is: the exposed span access location length of clamp nut and conducting rod is large, and the length of conducting rod is long; Because fastening bolt is in conducting rod side, need material many, cost is high.
Summary of the invention
The problem existing in order to overcome prior art, the purpose of this utility model is to provide the syndeton of a kind of oil-filled transformer low pressure connector lug and conducting rod, and this structure is installed reliable, is connected firmly; And owing to there is no clamp nut, save widely raw material, met the needs of producing, adapted to the requirement of national policy.
The purpose of this utility model is 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 the installing hole radially connecting on the top of conducting rod, on connector lug, be provided with the connector lug hole suitable with installing hole, connector lug is sleeved on conducting rod, and by being arranged on the fastening bolt locking in installing hole and connector lug hole; On conducting rod, be set with adjustment pad, and connector lug is pressed on porcelain vase on case lid by adjusting pad.
In the utility model, be processed with screw thread on the top of conducting rod, connector lug is pressed on porcelain vase on case lid by screw thread.On conducting rod, be provided with two installing holes, connector lug is sleeved on conducting rod by two fastening bolts.
In the utility model, connector lug is removed the retaining part that fastening bolt is installed; Conducting rod top machining screw, bottom is polished rod; Another connector lug bores two holes of wearing clamp nut with conducting rod screw thread corresponding position.
When assembling, conducting rod is installed below case lid, case lid top cover low pressure porcelain vase, then add adjustment plain cushion, then from conducting rod be threaded into connector lug until by porcelain vase consolidation be arranged on case lid, ensure sealing, finally penetrate fastening bolt and locked assembling.Adjust the effect of pad and be that suitably increase and decrease is to ensure that thrust enough seals when not overlapping when connector lug hole and conducting rod hole, the effect of fastening bolt is that locking connector lug closely, reliably, is guaranteed contact resistance with thread pitch between conducting rod to ensure contact.
The utility model has reduced clamp nut and 20mm left and right, the exposed position of conducting rod length on the basis of original structure, the length of effectively having reduced conducting rod, and owing to having saved clamp nut, further reduced cost; The retaining part that another former connector lug is installed fastening bolt has also obtained deleting.By the comparison of weighing of the conducting rod to different model specification and connector lug, average weight is reduced in 28% left and right.
The utility model is installed reliable, is connected firmly, and has saved raw material widely, has met the needs of producing, and has adapted to the requirement of national policy.

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.Be provided with two installing holes that radially connect on the top of conducting rod, on connector lug, be provided with the connector lug hole suitable with installing hole, in connector lug, be also provided with the screw thread suitable with conducting rod top, connector lug, and is locked by two fastening bolts 3 that are arranged in installing hole and connector lug hole by thread set on conducting rod; Connector lug has been removed the retaining part of traditional installation fastening bolt.On conducting rod, be set with and adjust pad 6, and adjustment pad is positioned at connector lug below.Connector lug is pressed on porcelain vase 5 on case lid 4 by adjusting pad.
When assembling, conducting rod is installed below case lid, case lid top cover low pressure porcelain vase, then add adjustment plain cushion, then from conducting rod be threaded into connector lug until by porcelain vase consolidation be arranged on case lid, ensure sealing, finally penetrate fastening bolt and locked assembling.Adjust the effect of pad and be that suitably increase and decrease is to ensure that thrust enough seals when not overlapping when connector lug hole and conducting rod hole, the effect of fastening bolt is that locking connector lug closely, reliably, is guaranteed contact resistance with thread pitch between conducting rod to ensure contact.
