Specific embodiment
Referring to Fig. 1-10, the utility model relates to a kind of oil duct support components suitable for transformer comprising several longitudinal directions
Stay 10 and several lateral connection sheets 20, the stay and the connection sheet crossover sites be connected with each other, formed in length and breadth
Latticed (or netted, as shown in Fig. 1 and Figure 10) of cross arrangement, the interconnection between the stay and the connection sheet
Mode is grafting.
The stay and connection sheet are made of insulating polymer material, preferably nylon.
The height of the stay should be higher than that the height of the connection sheet, due to the medium flow field direction of oil duct and prolonging for connection sheet
Stretch that direction is vertical, the space that the part that stay is higher than connection sheet is propped up constitutes the medium flow channels above connection sheet.
The bottom of the stay be preferably provided with for pass through the connection sheet lateral through slot 12, the connection sheet with institute
The lateral through slot that the position that stay intersects is embedded on the stay is stated, bottom surface and the bottom surface of the stay are generally aligned in the same plane.
The width of the connection sheet usually can be similar with the width of the lateral through slot on the stay or even be slightly larger than institute
The width of the lateral through slot on stay is stated, i.e., is preferably transition fit between the horizontal line through slot in the described connection sheet and the stay
