Description
Technical Field
The utility model belongs to the technical field of transformer installation, and relates to a transformer grounding structure.
Background
In order to ensure the stability of the safety and the performance of the transformer, the transformer arranged at high altitude has various grounding requirements such as neutral point grounding, lightning arrester grounding, transformer shell grounding (iron core grounding), JP cabinet grounding and the like, each grounding needs to be reliable and convenient to maintain, when the transformer is installed, the grounding guides are generally connected in parallel before grounding, then the grounding guides are connected into the ground through a grounding bus, in the prior art, a conductive bar is generally fixed on a transformer mounting seat or a stand column for supporting the transformer shell, each grounding branch is welded (or connected through a binding post) on the conductive bar, then the conductive bar is grounded through a bus (the grounding bus is not needed when the stand column is a concrete or a metal column), and the method is inconvenient in high-place operation, so that good contact and stable connection between each grounding branch and the line are difficult to ensure.
Disclosure of utility model
The utility model aims to solve the problems existing in the prior art and provide a transformer grounding structure, and the technical problem to be solved by the utility model is how to ensure reliable and convenient connection between each grounding branch and a grounding bus.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a transformer grounding structure, its characterized in that includes the mount pad, fixes the installation section of thick bamboo on the mount pad, bus post and ground connection bus, be provided with a plurality of intubates on the installation section of thick bamboo, each intubate all corresponds a branch post, the upper end of branch post has the branch wire and connects the line loop, the lower extreme of branch post has a breach, have on the bus post and insert the piece of establishing in each breach simultaneously, fix a position through a lock bolt between bus post and the installation section of thick bamboo.
Further, the insertion pipe is in spline connection with the branching column.
Further, a rubber sealing ring is arranged in the insertion tube.
Furthermore, two ends of the bus column are respectively provided with a plug.
During installation, the installation seat can be fixed on the transformer installation stand column or the installation seat, then the grounding bus is buried, after the transformer is installed, grounding branches pulled out of all grounding positions of the transformer are respectively connected with the branch columns, after the transformer is inspected to be error-free, the branch columns are inserted into the insertion pipe one by one, then the bus column is inserted, the bus column is rotated to be in electrical contact with the insertion piece and the notch, meanwhile, the limit of the branch column is realized, and finally the bus column is fixed on the cylinder through the locking bolt.

In the figure, 1, a mounting seat; 2. a mounting cylinder; 3. a bus post; 4. a ground bus; 5. a cannula; 6. a split column; 7. a wire branching and connecting ring; 8. a notch; 9. inserting sheets; 10. a locking bolt; 11. and (5) plugging.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
The transformer grounding structure as shown in fig. 1 and 2 comprises a mounting seat 1, a mounting cylinder 2 fixed on the mounting seat 1, a bus column 3 and a grounding bus 4, wherein a plurality of insertion pipes 5 are arranged on the mounting cylinder 2, each insertion pipe 5 corresponds to one branching column 6, the upper end of each branching column 6 is provided with a branching wire connecting ring 7, the lower end of each branching column 6 is provided with a notch 8, each bus column 3 is provided with an inserting piece 9 which can be simultaneously inserted in each notch 8, the bus column 3 and the mounting cylinder 2 are positioned through a locking bolt 10, and the insertion positions of the corresponding branching columns 6 are conveniently identified by spline connection between the insertion pipes 5 and the corresponding branching columns 6, so that the inserting pieces 9 and the notches 8 can synchronously correspond.
The rubber sealing ring is arranged in the insertion tube 5, so that the tightness between the insertion tube 5 and the branching column 6 is improved. The two ends of the bus bar 3 are respectively provided with a plug 11, one plug 11 is fixed at one end of the bus bar 3, the other plug 11 is connected with the grounding bus 4, and after the bus bar 3 is inserted into the mounting cylinder 2, the plugs 11 connected with the grounding bus 4 are connected with the end of the bus bar 3 in a threaded manner, which is the consideration of the sealing performance in the mounting cylinder 2 and the positioning of the bus bar 3 and the mounting cylinder 2.
During installation, the installation seat 1 can be fixed on the transformer installation stand or the installation seat 1, then the grounding bus 4 is buried, after the transformer is installed, grounding branches pulled out of all grounding positions of the transformer are respectively connected with the branch posts 6, after the transformer is inspected to be error-free, the branch posts 6 are inserted into the insertion pipes 5 one by one, then the bus posts 3 are inserted, the bus posts 3 are rotated to be in electrical contact with the insertion pieces 9 and the gaps 8, meanwhile, the limit of the branch posts 6 is realized, and finally the bus posts 3 are fixed on the cylinder through the locking bolts 10.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
