Abstract
The invention discloses a connecting structure of a low-voltage connector lug of an oil-immersed transformer and a conducting rod of the oil-immersed transformer. The connecting structure comprises the conducting rod and the connector lug. Radially-through installation holes are formed in the upper portion of the conducting rod, connector lug holes matched with the installation holes are formed in the connector lug, the conducting rod is sleeved with the connector lug and the connector lug and the conducting rod are locked through fastening bolts arranged in the installation holes and the connector lug holes. An adjusting gasket is arranged on the conducting rod in a sleeved mode and the adjusting gasket is located below the connector lug. The connecting structure is reliable to install and firm in connection, greatly saves raw materials, meets production requirements and meets the requirements 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 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
In order to overcome the problem of prior art existence, 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 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 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 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 present invention, 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 present invention, 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 present invention 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 present invention installs reliably, 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.
