Embodiment 1

[0054] figure 1 Schematically provides the basic structural diagram of the novel transformer of the embodiment of the present invention, as figure 1 As shown, the new transformer includes:

[0055] a top cover, the top cover comprising:

[0056] a horizontal portion 21, the horizontal portion is fixed on the transformer housing 11 through a second connecting piece;

[0057] The bending part 22, the bending part is arranged at the end of the horizontal part, bent downward; adjacent bending parts are connected together;

[0058] raised seat 81, such as figure 2 As shown, the raised seat is fixed on the horizontal part 21 of the top cover, the central axis of the raised seat is perpendicular to the top cover, the angle between the end and the central axis is an acute angle, and the adjacent end The angle between the normal lines of the parts is an acute angle;

[0059] Insulating porcelain bottle 41, the high-voltage access end 31 of the transformer passes through the throu...

Embodiment 2

[0064] The novel transformer of the embodiment of the present invention is different from Embodiment 1 in that:

[0065]like image 3 As shown, the included angle between the central axis of the raised seat 81 and the horizontal portion 21 of the top cover is an acute angle, the raised seat 81 is inclined toward the same side of the top cover, and the included angle between the end and the central axis is Right angle, the angle between the normal lines of adjacent ends is an acute angle; the insulating porcelain bottle 41 is fixed on the end, inclined towards the same side of the horizontal part of the top cover, and the included angle between adjacent insulating porcelain bottles 41 is an acute angle.

Embodiment 3

[0067] In the box-type substation according to the embodiment of the present invention, the box-type substation includes:

[0068] a box body, the box body includes a first chamber, a second chamber and a third chamber isolated from each other;

[0069] A high-voltage switchgear, the high-voltage switchgear is arranged in the first chamber, and the output high-voltage power is sent to the transformer for step-down (or the boosted high-voltage power output by the transformer is sent to the high-voltage switchgear); as Figure 4-5 As shown, the high-voltage switchgear includes:

[0070] The switchgear and the operation panel 211 are all existing technologies in the art, and will not be described in detail here.

[0071] The closed container 251 is welded as a thick steel plate, the closed container is arranged on the rear side of the operation panel, and the inside is filled with insulating gas, such as sulfur hexafluoride, and the switchgear is arranged in the closed container...

Abstract

The invention discloses a novel transformer and a box-type substation. The transformer comprises a top cover, high-voltage access ends, ascending seats, insulating porcelain insulators, fixed parts and connecting parts, wherein the ascending seats are fixed on the top cover; the insulating porcelain insulators are fixed at the end parts of the corresponding ascending seats; the high-voltage access ends pass through corresponding through holes in the insulating porcelain insulators; an included angle between the central axial lines of the adjacent insulating porcelain insulators is an acute angle; one ends of the fixed parts jack the corresponding ascending seats while the other ends of the fixed parts press the corresponding insulating porcelain insulators; and the connecting parts are used for connecting the fixed parts and the top cover. The novel transformer and the box-type substation have the advantages of good insulating effect, high strength and the like.

Description

technical field [0001] The invention relates to a voltage transformer, in particular to a novel transformer and a box transformer. Background technique [0002] Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. [0003] Existing transformer top covers are flat plates, and in order to improve the protection strength, the thickness of the top cover is about 6mm. In addition, the fixing method of the porcelain bottles on the outer side of the high-voltage access end is: the porcelain bottles are arranged vertically, and the distance between the porcelain bottles is limited on the effective area of ​​the top cover, which reduces the insulation effect to a certain extent.
