The improved structure is that the conducting rod is sealed by sealing elements on the inner side and the outer side of the oil tank, and the double sealing effect is achieved.
Description
Technical Field
The utility model belongs to the technical field of the transformer, concretely relates to inside and outside seal structure of modular transformer low pressure conducting rod.
Background
The low-voltage conducting rod of the existing combined transformer is fixed on the wall of the tank through a sealing element, a pressure plate and a bolt (as shown in figure 2). The structure is a unilateral fixed sealing structure, if the sealing element is damaged, the sealing element can be replaced only by discharging the insulating oil of the combined transformer, and the insulating oil is added into the oil tank of the combined transformer after the sealing element is replaced to be continuously used. A large amount of labor hour is wasted in the process, and insulating oil is deteriorated, polluted, moistened and the like in the oil discharging and refueling process. Thereby causing great potential safety hazard to the operation of the combined transformer.
Disclosure of Invention
In order to overcome the shortcoming of the prior art, the utility model provides a modular inside and outside seal structure of transformer low pressure conducting rod, the structure after the improvement is that the conducting rod will have the sealing member to seal in the oil tank inboard and the outside, plays double seal's efficiency.
The utility model discloses a realize through following technical scheme: a magnetic shield plate is fixed on the outer side of a box wall of a combined type transformer low-voltage conducting rod, the conducting rod penetrates through the box wall and the magnetic shield plate to be installed and fixed, a sealing element I is installed on the outer side, located on the box wall, of the conducting rod, a pressing plate I is placed on one side, far away from the magnetic shield plate, of the sealing element I, and a bolt I penetrates through the pressing plate I to be in threaded connection with the magnetic shield plate; the conducting rod is located the inboard of tank wall and installs sealing member II, and sealing member II keeps away from clamp plate II has been placed to one side of tank wall, and bolt II passes clamp plate II and tank wall threaded connection.
Further, the magnetism isolating plate is a rectangular plate.
Further, the magnetism isolating plate is welded on the outer side of the box wall.
The utility model has the advantages that: compared with the prior art, the conducting rod of the application is sealed by the sealing element on the inner side and the outer side of the oil tank, and the double-sealing effect is achieved. That is, the inner sealing element alone can make the conducting rod oil-tight, and the outer sealing element alone can make the conducting rod oil-tight. And when maintaining, changing external seal spare, need not take apart the oil tank, guarantee that inside conducting device is motionless. This structure can save a large amount of costs of labor, and has guaranteed the insulating effect of insulating oil, and then has guaranteed the operation safety of combination formula transformer.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic diagram of a prior art structure;
in the figure, 1, a conducting rod 2, bolts I and 3, pressure plates I and 4, sealing elements I and 5, pressure plates II and 6, sealing elements II and 7, bolts II and 8, box walls 9 and a magnetism isolating plate.
Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in fig. 1, in the internal and external sealing structure of the low-voltage conducting rod of the combined transformer, a rectangular magnetic isolation plate 9 is fixed on the outer side of a box wall 8, and the magnetic isolation plate 9 is welded on the outer side of the box wall 8. The magnetic isolation plate with the tapping blind wire is welded on the outer side of the box wall 8, so that the internal and external sealing structural effect can be achieved. The conductive rod 1 penetrates through the tank wall 8 and the magnetism isolating plate 9 to be installed and fixed, a sealing element I4 is installed on the outer side, located on the tank wall 8, of the conductive rod 1, a pressing plate I3 is placed on one side, away from the magnetism isolating plate 9, of the sealing element I4, and a bolt I2 penetrates through the pressing plate I3 to be in threaded connection with the magnetism isolating plate 9; and the conducting rod 1 is positioned on the inner side of the box wall 8 and is provided with a sealing element II 6, the sealing element II 6 is far away from one side of the box wall 8 and is provided with a pressing plate II 5, and a bolt II 7 penetrates through the pressing plate II 5 and is in threaded connection with the box wall 8.
The inner side and the outer side of the oil tank of the conducting rod are sealed by the sealing parts, so that the effect of double sealing is achieved; that is, the inner sealing element alone can make the conducting rod oil-tight, and the outer sealing element alone can make the conducting rod oil-tight. And when the sealing element outside the oil tank is maintained and replaced, the oil tank does not need to be disassembled, and the inner conductive device is ensured to be fixed. This structure can save a large amount of costs of labor, and has guaranteed the insulating effect of insulating oil, and then has guaranteed the operation safety of combination formula transformer.
