And the output end of the driving motor is connected with blowing fan blades. The constant-temperature protection high-voltage transformer with the chassis anti-sedimentation structure is provided with the rotating pull rod and the eccentric wheel, the eccentric wheel is used for driving the transverse supporting arm to vertically ascend and descend, and the height of the positioning chassis is adjusted according to the depth of frozen soil at the bottom of the transformer shell.

Description

technical field [0001] The invention relates to the technical field of high-voltage transformers, in particular to a constant-temperature protective high-voltage transformer with a chassis anti-subsidence structure. Background technique [0002] Permafrost thawing refers to the subsidence phenomenon when the permafrost melts. The volume of various ices in the permafrost shrinks after melting, causing the soil to sink due to its own weight. Subsidence, the rheology of permafrost has a serious impact on the construction of roads and transformers, and it is easy to cause frost heave, thawing and other adverse diseases. The constant temperature protection high-voltage transformer with chassis anti-subsidence structure is supported by the bottom of the transformer to avoid During the transition from winter to spring, the moisture inside the permafrost is discharged, which affects the stability of electrical components and wire connections inside the transformer; [0003] For exa...

Problems solved by technology

[0003] For example, in the CN201820608126.0 transformer, the anti-settling device stirs the insulating oil in the transformer box to prevent the insulating oil from settling, resulting in a lower density of the upper layer of insulating oil and a higher density of the bottom layer of insulating oil, which makes the heat dissipation of the transformer uneven. The transformer in the comparative document shows that the cooling oil inside the transformer is treated horizontally through the internal structure, and during the use of the device, it is difficult to adjust the depth and strength of the bottom of the transformer according to the depth of the permafrost layer at the base of the device. During use, the electrical components and wire connections of the transformer will be affected by settlement;

[0004] When electrical equipment gets damp, the first performance is that the insulation performance of the equipment is reduced, and the insulation aging is accelerated. According to the current medium theory, the increase in ambient humidity will increase the conductivity of the dielectric and the tangent of the dielectric loss angle. After vibration, it cracks and moisture enters the crack. , Secondly, with the increase of humidity, the oxidation and corrosion of exposed metal conductors will generally be accelerated. The existing high-voltage transformers lack moisture-proof and drying structures, which increases the contact resistance at the conductor joints, causing local overheating, and long-term use. The service life of electrical equipment in a humid environment will be greatly reduced, causing serious electrical accidents
