DETAILED DESCRIPTION

[0020] The utility model is further described below in combination with the drawings and examples.

[0021] The transformer is a device for changing AC voltage by using electromagnetic induction principle, which is mainly composed of primary coil, secondary coil and iron core (or magnetic core).

[0022] The main functions of the transformer include voltage transformation, current transformation, impedance transformation, isolation and voltage stabilization (in the magnetic saturation transformer), and its working principle can be simply described as "electricity generates magnetism, and magnetism generates electricity": when AC current passes through the primary coil, AC magnetic flux is generated in the iron core, and this magnetic flux passes through the primary winding and the secondary winding, and according to the electromagnetic induction law, induced electromotive force is generated in the primary winding and the secondary winding respectively, thereby realizing voltage transformation.

[0023] The transformer plays an important role in the power system, which is used for economical transmission, reasonable distribution and safe use of the electric energy generated by power plants. For example, in residential areas and factories, step-down transformers convert high-voltage electric energy into low-voltage electric energy for daily equipment and power equipment.

[0024] The pipeline support structure of the transformer is an important part in the field of transformer manufacturing equipment, which mainly plays the role of supporting and fixing the oil pipe and other pipelines in the transformer to ensure the stable operation of the transformer.

[0025] Specifically, a typical transformer pipeline support structure system includes a transformer oil tank, a radiator, a horizontal oil pipe and an oil pipe support, etc., wherein the transformer oil tank is fixedly installed with the radiator on one side, and the horizontal oil pipe is fixedly installed on the side close to the radiator, and the horizontal oil pipe is also fixedly installed with the radiator. In order to support and fix the horizontal oil pipe, the oil pipe support plate is fixedly installed at the bottom of the horizontal oil pipe, and the bottom of the oil pipe support plate is fixedly connected with the oil pipe support.

[0026] The pipeline support structure of a transformer is one of the important guarantees for its stable operation. It ensures the stability and safety of the oil pipes in the transformer through a series of careful design and installation. However, the pipeline support structure of a transformer often has some problems in actual use. Some common problems and their causes are listed below: 1. Loose or damaged pipeline support structure: The pipeline support structure may become loose or damaged due to long-term operation, vibration or external impact, causing the pipeline to be unstable or displaced. Cause: It may be due to improper tightening during installation, material aging, long-term vibration or external impact. 2. Oil leakage: The transformer bushing or oil tank connected to the pipeline may leak oil, affecting the normal operation of the equipment and the surrounding environment. Cause: It may be due to loose sealing of the bushing, internal oil seepage along the cracks, or excessive oil overflow due to internal oil fluctuations. In addition, damaged pipeline support structure may also indirectly cause oil leakage. 3. Decreased sealing performance: The sealing material around the pipeline support structure may be aged, cracked or hardened, causing the sealing performance to decrease. Cause: Long-term exposure to oil, moisture and other environments, as well as long-term vibration or long service life, may accelerate the aging of the insulation material. 4. Electrical fault: The electrical connection near the pipeline support structure may cause electrical fault due to poor contact, poor connection or poor welding. Cause: It may be due to improper installation, long-term vibration causing loose connection, or poor welding quality. 5. Pipeline blockage: The internal pipeline may be blocked by oil dirt, impurities and other factors, affecting the flow and heat dissipation of the oil. Cause: It may be due to poor oil quality, long-term lack of maintenance and cleaning, or unreasonable pipeline design causing poor oil flow.

[0027] In summary, the pipeline support structure of a transformer may encounter problems such as loose damage, oil leakage, decreased sealing performance, electrical fault and pipeline blockage during actual use. These problems are mostly related to material aging, improper installation, long-term vibration, external impact and insufficient maintenance. Therefore, during the operation and maintenance of the transformer, the inspection and maintenance of the pipeline support structure should be strengthened to ensure its stable and reliable operation.
