Description
(I) technical field
The utility model relates to a partial component of a transformer, in particular to a ground wire leading-out device of a lightning arrester for the transformer.
(II) background of the utility model
At the present stage, in order to prevent the transformer from being struck by lightning, the lightning arrester is often additionally arranged beside a transformer bushing, and a grounding lead of the lightning arrester cannot be directly connected to a transformer oil tank, because if the grounding lead of the lightning arrester is directly connected to the transformer oil tank, the transformer oil tank has certain residual voltage when the lightning arrester is broken down, and thus the transformer is not beneficial to safe operation. Therefore, when the transformer is installed, a support is often installed beside the transformer as a foundation, an insulator is additionally installed on the support, and the lightning arrester grounding lead is led down to be grounded through the insulator on the support. Although the phenomenon that the transformer oil tank is electrified is solved, the workload of installation workers is increased, the using amount of the grounding wire of the arrester is increased, the occupied area of the transformer is increased, and the capital investment of transformer substation construction is increased.
Disclosure of the utility model
In order to make up for the defects of the prior art, the utility model provides the grounding wire leading-out device of the arrester for the transformer, which reduces the installation workload, the occupied area, the cost and the operation and maintenance convenience.
The utility model is realized by the following technical scheme:
the utility model provides a lightning arrester earth connection eduction gear for transformer, includes the transformer body, and the sleeve pipe is installed to transformer body top, and the connection of transformer body lateral part is equipped with radiator, characterized by: the lightning arrester installed on the transformer body is connected to the outer side of the sleeve, the lightning arrester is connected with a grounding lead, the grounding lead is fixed through an insulator and leads to the lower portion of the transformer body to be grounded, the insulator is installed on the welding base, and the welding base is welded to the radiator.
The insulator includes upper insulator and lower insulator, and upper insulator installs on last welding base, and lower insulator installs under on the welding base.
The upper welding base is welded at the upper end part of the radiator, and the lower welding base is welded at the lower end part of the radiator.
The utility model has the beneficial effects that: the workload of field installation of the transformer is reduced, the using amount of the grounding wire of the lightning arrester is reduced, the occupied area of the transformer is reduced, the capital investment is reduced for the construction of the transformer substation, and the operation and maintenance after the transformer is put into operation are facilitated.

The utility model will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention;
in the figure, 1 transformer body, 2 sleeve pipes, 3 radiator, 4 lightning arrester, 5 grounding lead, 6 insulator, 7 welding base, 8 upper insulator, 9 lower insulator, 10 upper welding base and 11 lower welding base.
(V) detailed description of the preferred embodiments
The attached drawing is an embodiment of the utility model. The transformer comprises a transformer body 1, a sleeve 2 is installed above the transformer body 1, a radiator 3 is connected to the side of the transformer body 1, a lightning arrester 4 installed on the transformer body 1 is connected to the outer side of the sleeve 2, the lightning arrester 4 is connected with a grounding lead 5, the grounding lead 5 is fixed through an insulator 6 and leads to the lower portion of the transformer body 1 to be grounded, the insulator 6 is installed on a welding base 7, and the welding base 7 is welded on the radiator 3. The insulator 6 comprises an upper insulator 8 and a lower insulator 9, the upper insulator 8 is arranged on an upper welding base 10, and the lower insulator 9 is arranged on a lower welding base 11. The upper welding base 10 is welded to the upper end of the heat sink 3, and the lower welding base 11 is welded to the lower end of the heat sink 3.
The grounding wire leading-out device of the arrester for the transformer is adopted, the grounding wire leading-out device is completed when the transformer is installed on site, the upper welding base 10 and the lower welding base 11 are respectively welded at the upper end and the lower end of the radiator 3, the upper insulator is installed on the upper welding base 10, the lower insulator 9 is installed on the lower welding base 11, the grounding lead 5 of the arrester 4 is fixed through the upper insulator 8 and the lower insulator 9 and is led to the lower part of the transformer body 1 to be grounded, and the grounding lead 5 of the arrester 4 is insulated from the radiator 3 due to the support of the insulator 6, so that the possibility that the transformer shell is electrified after the arrester 4 is punctured is avoided. The transformer is mainly applied to power transformers with the voltage class of 35kV and above.
