Abstract
The utility model relates to a dry transformer protection shell made from heteromorphic aluminum shape. The dry transformer protection shell is a cuboid case body structure that has a door and consists of four side surfaces, a top surface and a bottom surface, and all upright posts of the case body frame are formed by fixedly connected cubic aluminum alloy shapes 6 with wings 3, and the wings are positioned at the opposite side surfaces and perpendicular to each other. Two cubic aluminum alloy shapes formed into the upright posts are arranged in right angle, with a groove shaped or boss shaped connector 2 on the opposite sides. Two supporting claws of a protecting board 1 are engaged into the connectors to shape the corner into arc shape, trapezoid shape or polygonal shape. The shell can also be formed by four independent side surfaces into a whole, which is simple in production and has strong intensity. The utility model can be packed by stacking to be transported.
Description
Affiliated technical field
The utility model relates to a kind of protector of dry-type transformer.
Background technology
At present, produce and the frame of the dry-type transformer guard shield that uses is that square aluminium alloy extrusions by the band wing is formed by fixedly connecting, promptly two orthogonal wings and side are fixedly linked.When this aluminium alloy extrusions is used as the standpipe corner, be connected with upper and lower frame with exposing threeway usually, the stile of Xing Chenging had both shown thin like this, inconvenient again dismounting.Again because the volume of dry-type transformer guard shield is bigger, general appearance is of a size of: length * wide * height=(1800～2100) * (1200～1400) * 2142mm, and when dry-type transformer is installed, the shell of at first will dismantling, after treating that transformer installs, again shell is assembled.Because the shell that traditional section bar manufactures both had been unfavorable for dismounting, also be not easy to install, repeatedly also influence bulk strength after the dismounting, and time-consuming, obvious edges and corners is also arranged all around.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, intensity is high, the dry-type transformer guard shield of easy accessibility.
The utility model is to realize like this, the rectangular box structure that this dry-type transformer guard shield is made up of four sides and upper and lower bottom surface, have at least one side and open the door, four columns of this guard shield frame all are to be formed by fixedly connecting by two square aluminium alloy extrusions that have wing, wing on this square aluminium alloy extrusions side has two, on the opposite flank, and vertical mutually; Two square aluminium alloy extrusions that constitute column arrangements that meet at right angles has groove shaped or boss shape connector on its opposite flank, two of backplate prop up pawls and snap on this connector and constitute.
Four columns of dry-type transformer guard shield described in the utility model all are by two fixedly connected making of square aluminium alloy extrusions, can make this guard shield manufacture four independently four faces, be assembled into an integral body then, the crown chakra exterior feature that forms after the assembly unit, the profile of going to the bottom also are easy to link to each other with last end face, bottom surface, and making is simple, intensity is high.Backplate of connector plug-in mounting can be passed through in the turning that constitutes after the assembly unit, makes the turning of this guard shield constitute structures such as arc surface, trapezoidal, many prismatics, square, the shell of the dry-type transformer that manufactures like this more attractive in appearance, generous.Also can take stacking form, packing and transporting during transportation.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the enlarged drawing of the A-A section of Fig. 1;
Fig. 3 is another embodiment of the A-A profile of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.This dry-type transformer guard shield is the rectangular box structure that is composed of a fixed connection by four sides and upper and lower bottom surface, and has and open the door.The column of this guard shield frame all is to be formed by fixedly connecting by angle bar or alternate manner by two square aluminium alloy extrusions 6 that have wing 3, and the wing 3 on the side of this square aluminium alloy extrusions 6 has two, and vertical mutually; Two square aluminium alloy extrusions 6 fixedly connected form right angles, have groove shaped or boss shape connector 2 on its opposite flank, through this connector 2 backplate 1 is installed, the outer surface of backplate 1 can be an arc surface, also can be structures such as trapezoidal, many prismatics, square.The side panel 7 of this dry type transformer protecting crust is fixedlyed connected formation completed cases structure with the wing 3 on the square aluminium alloy extrusions 6.For the ease of the side panel 7 of protecting crust is installed, also be provided with button line seat 5 on the side of square aluminium alloy extrusions 6, the line 4 of buckleing that fixation side panel 7 is installed on this button line seat 5 constitutes.
Claims (2)
1, a kind of dry-type transformer guard shield, this guard shield is made up of four sides and upper and lower bottom surface, and have the rectangular box structure of opening the door, it is characterized in that: the column of this protecting sheathing frame all is to be formed by fixedly connecting by two square aluminium alloy extrusions (6) that have wing, the wing (3) that has on this square aluminium alloy extrusions (6) has two, on relative side, and vertical mutually; Two the square aluminium alloy extrusions (6) that constitute column arrangements that meet at right angles has groove shaped or boss shape connector (2) on its opposite flank, two pawls of backplate (1) snap in this connector (2) and go up formation.
