A kind of constant temperature protection high voltage transformer with chassis anti-settling structure

Abstract

The invention discloses a constant temperature protection high-voltage transformer with a chassis anti-settling structure, comprising a transformer shell, an insulating terminal and a first lifting chassis. An outer heat dissipation box is arranged on both sides, and a solar panel is connected directly above the outer heat dissipation box. The insulating terminal is installed directly above the transformer shell, and a vertical support is welded and fixed directly under the transformer base. The outer side of the vertical support column is welded and fixed with a rectangular guide rail, the inside of the transformer casing is placed and fixed with an instrument box, and the output end of the drive motor is connected with a blower fan blade. The constant temperature protection high-voltage transformer with chassis anti-settling structure is provided with a rotating pull rod and an eccentric wheel. The eccentric wheel is used to drive the lateral support arm to vertically lift, and the height of the positioning chassis is adjusted according to the depth of the frozen soil at the bottom of the transformer shell.

Description

Technical field [0001] The invention involves high -voltage transformers technology fields, which are specific to a constant temperature protection high -voltage transformer with a constant temperature protection structure with a chassis anti -sedimentation structure. Background technique [0002] Frozen soil melting refers to the sinking phenomenon when the frozen soil is melted. After the various ice melting in the frozen soil is reduced, the volume is reduced, so that the soil is sinking due to self -sinking, and the ice becomes after the water becomes water. Sinking, many years of frozen soil has a serious impact on roads and transformer construction, and it is very easy to cause adverse diseases such as frozen and bloating, melting, and the constant temperature protection high -voltage transformer with a chassis anti -sedimentation structure. During the transition in winter and spring, the excretion of water inside the frozen soil affects the stability of the electrical comp...

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
