Description

Technical Field

[0001] The utility model relates to the technical field of oil pipelines, in particular to an oil pipeline for transformer oil processing. Background Art

[0002] Transformer oil, also known as transformer oil, is an oily liquid used as an insulating and cooling medium in transformers and other electrical equipment. Transformer oil is the most important insulating and cooling medium in transformers. Whether it is a power transformer, a distribution transformer or a special transformer, such as an electric furnace transformer, a rectifier transformer, etc., transformer oil is required.

[0003] The specific processing steps of transformer oil are as follows:

[0004] 1. Purchase transformer raw oil;

[0005] 2. Then filter and remove impurities from the transformer raw oil to ensure purity;

[0006] 3. Then the transformer raw oil after impurities removal is deeply processed to form the finished transformer oil;

[0007] 4. Then the treated transformer oil product is tested and inspected. The test items include breakdown voltage, dielectric loss, viscosity, moisture, acid value, etc.;

[0008] 5. Finally, the finished transformer oil is stored and packaged for later transportation.

[0009] Among them, when the transformer raw oil is deeply processed, the transformer raw oil is generally transported to a mixing box through an oil pipeline, and then the transformer raw oil is stirred and mixed with the antioxidant additives preset in the mixing box to form a finished transformer oil with antioxidant properties.

[0010] At present, the existing oil pipeline structure for transformer raw oil set on the mixing box generates friction static electricity between the transformer raw oil and the inner wall of the oil pipeline when the transformer raw oil is transported. The accumulation of static electricity will cause sparks, which will affect the insulation performance of the transformer raw oil.

[0011] In addition, the existing oil pipeline structure for transformer raw oil arranged on the mixing box will accumulate oil scale of one quality on the inner wall of the oil pipeline after long-term use. If it is not cleaned, directly transporting transformer raw oil of another quality will cause mixing with the oil scale, affecting the quality of the finished oil made from the next batch of transformer raw oil of another quality in the later stage.

[0012] The above problems are widespread and urgently need to be improved. Utility Model Content

[0013] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes an oil pipeline for transformer oil processing.

[0014] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0016] Furthermore, the static conductive sleeve is welded on the outer wall surface of the oil pipeline, and the static conductive sleeve is a cylindrical ring structure as a whole and is made of red copper.

[0017] Furthermore, the metal static conductive plate is embedded in the ground, the metal static conductive plate is made of aluminum-titanium alloy as a whole, and the upper and lower ends of the static conductive wire are fixedly welded to the static conductive sleeve and the metal static conductive plate respectively.

[0018] Furthermore, the stable mounting plate is arranged on the outer wall surface of the metal electrostatic conductive plate, and the stable mounting plate and the bolts form a group, with a total of four groups arranged in a circle. The bolts pass through the stable mounting plate and are threadedly connected to embedded nuts embedded in the ground.

[0019] Furthermore, the heating plate is embedded in the inner wall of the liquid storage tank, and the inner wall surface of the heating plate is flush with the inner wall surface of the liquid storage tank.

[0020] Furthermore, the infusion tube is connected to the left end of the liquid pump, and the infusion tube is made of stainless steel as a whole and has an L-shaped cross-section.

[0021] Furthermore, the liquid extraction tube is connected to the lower end of the liquid extraction pump and penetrates into the liquid storage tank, and a gap exists between the lower end surface of the liquid extraction tube and the inner cavity wall surface of the liquid storage tank.

[0022] The utility model provides an oil pipeline for transformer oil processing, which has the following beneficial effects:

[0023] 1.

[0033] Antioxidant additives can be added through the feeding pipe 21, and the stirring group 3 is a common stirring structure.

[0034] In detail, the static conductive sleeve 4 is welded on the outer wall of the oil pipeline 1. The static conductive sleeve 4 is a cylindrical ring structure and is made of red copper. The red copper material has excellent static conductive efficiency and is easy to weld.

[0035] Furthermore, the metal electrostatic conductive plate 5 is embedded in the ground 20. The metal electrostatic conductive plate 5 is made of aluminum-titanium alloy. The upper and lower ends of the electrostatic conductive wire 41 are fixedly welded to the electrostatic conductive sleeve 4 and the metal electrostatic conductive plate 5 respectively. The aluminum-titanium alloy material has excellent electrostatic conduction efficiency, and the body is corrosion-resistant, waterproof and durable.

[0036] Furthermore, the stable mounting plate 51 is arranged on the outer wall surface of the metal static conductive plate 5. The stable mounting plate 51 and the bolts 52 form a group, and there are four groups arranged in a circle in total. The bolts 52 pass through the stable mounting plate 51 and are threadedly connected to the embedded nuts embedded in the ground 20, thereby improving the structural stability between the static conductive wire 41 and the ground 20.

[0037] In more detail, the heating plate 61 is embedded in the inner wall of the liquid storage tank 6, and the inner wall surface of the heating plate 61 is flush with the inner wall surface of the liquid storage tank 6.
