Problems solved by technology

[0002] The environment of offshore oil drilling platforms is harsh, and there are many environmental factors that are not conducive to the normal operation of transformers, such as: air relative humidity, condensation, oil mist, salt mist and mold, ship vibration and shock, and the impact of sea storms. The performance of ordinary transformers used in the field is far from meeting the needs of offshore oil drilling platforms

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and concrete example for further description:

[0023] Such as figure 1 , 2 As shown in and 3, 1 is the square iron and insulation, 2 is the steel washer, 3 is the side screw, 4 is the high-voltage side clamp, 5 is the iron core, 6 is the low-voltage side clamp, 7 is the ground plate, and 8 is the clamp insulation , 9 are foot pads, 10 are pad foot insulation, 11 are pads, and 12 are pull screw rods. Two pairs of hanging screws are used for positioning between the upper part of the body and the shell, six-point positioning is carried out between the lower part of the body and the shell through foot bolts, and there is a gap between the welding of the shell side wall and the clamping parts of the body. steel for positioning. That is, the ten-point positioning of the body: the three feet on the lower part of the body form a six-point positioning, which is fixed to the bottom of the shell by bolts and nuts; the hanging scre...

Abstract

This invention relates to a transformer on a sea platform, in which, its winding is formed by multiple transposed conductors, longitudinal gas channels are set between high voltage coils, formation bracing strips are used to isolate the windings and the insulation tube to form axial gas channels, which are formed between low voltage coils and between coils and the high voltage tube, a top-blown cooling fan is set at the bottom of the coils, bracing plates are used to fix many places between a core post and the internal winding filled with insulation bars, the places between internal and external windings are fixed by bracing strips, an U-steel and a square iron are welded to an iron yoke, multiple pairs of screw rods are used to locate the top of the device and the shell and positions between the bottom of the device and the shell are fixed by foot screws and the side wall of the shell is welded with locating round bars.

Description

technical field [0001] The invention relates to a power transformer, in particular to an offshore platform transformer. Background technique [0002] The environment of offshore oil drilling platforms is harsh, and there are many environmental factors that are not conducive to the normal operation of transformers, such as: air relative humidity, condensation, oil mist, salt mist and mold, ship vibration and shock, and the impact of sea storms. The performance of ordinary transformers used in the field is far from meeting the needs of offshore oil drilling platforms. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects of the prior art, and provide an offshore platform transformer that can adapt to harsh offshore environmental conditions. [0004] In order to achieve the above-mentioned purpose, the cooling form of the offshore platform transformer of the present invention is dry type, the high-voltage coil is ca...
