Abstract
The utility model relates to a transformer bushing; a conductive pole is arranged in the middle of a ceramic bushing; a copper nut in the middle of a ceramic cap is in spiral connected with the conductive pole provided with the ceramic bushing with a matched spacing; the plane protruding platform on the conductive pole and the inner plane in the ceramic bushing is closely arranged through the sealing ring on two sides of the inner plane in the ceramic bushing and locked together by a gasket and a nut screwed on the conductive pole. A ceramic cap comprises a ceramic lid, filling material and a copper nut from outer to inner; a circular spring is embedded into a groove of the ceramic bushing and pressed into the groove by a pressing board. A bolt presses an outer protruding step, a sealing ring and an oil box wall together by the pressing board and the circular spring. The utility model has the advantages of providing a transformer bushing, in which the electriferous part is not directly exposed, the accidents does not happen due to the weather factors or human factors, at the same time, the ceramic lid is not easy fallen in high-altitude installation.
Description
Affiliated technical field
The utility model relates to a kind of bushing shell for transformer, belongs to the power transformer technical field.
Background technology
In the existing power transformer technology, the input terminal of 6-10KV power transformer sleeve pipe all is open use, outside charged position is directly exposed to.Often accidents happened because of weather conditions or human factor for this structure, and short circuit hopscotch outage sometimes when serious personal injury accident can take place.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned technology, provides outside a kind of charged position is not directly exposed to, can be because of weather conditions or the human factor bushing shell for transformer that accidents happened, and porcelain covers and is not easy to fall down when installing in the high-altitude simultaneously.
The technical solution of the utility model is: a kind of bushing shell for transformer, conducting rod are contained in the middle of the porcelain bushing, and the porcelain cap is screwed on the conducting rod and with the porcelain bushing matched in clearance and installs.
Described conducting rod is provided with a plane boss, an alignment pin and a strip wiring hole, and conducting rod also joins with copper conductor.Be provided with inner plane in the porcelain bushing, be provided with notch in the inner plane.Inner plane in plane boss on the conducting rod and the porcelain bushing is installed by the sealing ring tight fit on porcelain bushing inner plane both sides and by being screwed in packing ring on the conducting rod, nut check together.Alignment pin on the conducting rod is inlaid in the notch on the porcelain bushing inner plane.
Described porcelain cap outer ring is the porcelain lid, and inner ring is a copper nut, is filled with inserts between porcelain lid and the copper nut, and described inserts is a cement.The porcelain cap is screwed on the external screw thread of conducting rod by the copper nut of centre.
Described porcelain bushing cylindrical is provided with groove, evagination step and wire-netting aperture, one coil component spring is inlaid in the groove of porcelain bushing and by pressing plate and is pressed in the groove, and bolt closely is pressed against evagination step, sealing ring and oil tank wall together by pressing plate and coil component spring.
Grid line is inserted in the wiring hole of conducting rod and passes wire-netting aperture and electrical network joins during installation.The copper conductor and the transformer coil that join with conducting rod join.
The utility model has the advantages that provides outside a kind of charged position is not directly exposed to, can be because of weather conditions or the human factor bushing shell for transformer that accidents happened, and porcelain covers and is not easy to fall down when installing in the high-altitude simultaneously.
The utility model is described in further detail below in conjunction with drawings and Examples.
