Overview of Transformer Insulation Sleeve

The transformer insulation sleeve is the primary insulation device outside the transformer box, used to ensure the insulation of the transformer winding wires. It consists of multiple parts, including the central insulated capacitor core, external insulated upper and lower porcelain components, etc. According to the voltage level, there are various forms of bushings, such as pure ceramic, oil-filled bushings, and capacitor bushings. During the operation of a transformer, the insulation sleeve through which the winding leads is one of its current-carrying components, which needs to withstand the load current and short-circuit current.

Characteristics of Transformer Insulation Sleeve:

1. Excellent electrical insulation performance: It can effectively prevent the adverse effects of current on wires, cables, or equipment.

2. High-temperature resistance: Made of high-temperature resistant materials, it can maintain excellent performance in high-temperature environments.

3. Corrosion resistance: It can effectively prevent chemical substances from causing corrosion damage to wires, cables, or equipment.

4. Antiaging performance: Maintain stable performance in long-term use and effectively extend service life.

5. Good mechanical strength and sealing performance: able to withstand instantaneous overheating in the event of a short circuit, with a small appearance, small weight, good sealing performance, strong versatility, and easy maintenance.

Application of Transformer Insulation Sleeve

1. Insulation protection: The insulation sleeve of the transformer can provide insulation protection for the connection terminals of the transformer, prevent the degradation of the insulation performance of electrical equipment, and ensure the reliable operation of the equipment.

Storage Conditions for the Transformer Insulation Sleeve

1. Environmental requirements: Transformer insulation sleeves should be stored in a dry and clean environment to prevent moisture and pollution. A humid environment may decrease the insulation sleeves' performance and even cause electrical faults.

2. Temperature control: The temperature of the storage environment should be kept stable to avoid being too high or too low. Temperature fluctuations may affect the performance and service life of insulation sleeves.

3. Avoid direct sunlight: Long periods of direct sunlight may accelerate the aging of insulation sleeves and affect their insulation performance. Therefore, direct sunlight should be avoided.

4. Avoid mechanical pressure and impact: During storage and transportation, excessive mechanical pressure and impact should be applied to the insulation sleeve to avoid damage.

5. Regular inspection: The appearance and performance of the insulation sleeve should be checked regularly to ensure its normal operation. Any abnormalities or damages should be promptly addressed or replaced.

FAQ

Q1

What is the role of transformer insulation sleeves in the power system?

Re:The transformer insulation sleeve plays a crucial role in the power system, mainly serving as an insulation protection device for transformer winding wires to ensure the regular operation of transformers.

Q2

How can transformer insulation sleeves ensure the regular operation of transformers?

Re:The transformer insulation sleeve ensures the regular operation of the transformer by providing reliable insulation and current carrying capacity. It can withstand complex environmental factors such as voltage, present, and temperature during operation, effectively preventing existing damage to the transformer winding wires and ensuring the stable operation of the transformer.

Q3

What are the differences in the application of transformer insulation sleeves at different voltage levels?

Re:The form of transformer insulation sleeve varies according to different voltage levels. For example, pure ceramic bushings are mainly used in transformers of 10kV and below, oil-filled bushings are commonly used in transformers of 35kV level, and capacitor bushings are used in high-voltage transformers of 100kV and above. These different types of sleeves use other materials and structures to meet the insulation requirements of varying voltage levels.

Q4

How do you install and maintain transformer insulation sleeves correctly?

Re:When installing and maintaining transformer insulation sleeves, it is necessary to follow specific operating procedures and precautions. Firstly, before installation, the casing should be inspected to ensure its appearance is intact and undamaged. Secondly, installation should be carried out according to the prescribed procedures to avoid accidental operations. Thirdly, regularly maintain and inspect the casing, including reviewing its appearance and insulation performance, to identify and address potential issues promptly. Finally, the casing should be kept clean and dry to prevent the impact of dirt and moisture on insulation performance.

Q5

What is the development trend of transformer insulation sleeves?

Re:With the continuous development and technological progress of the power system, transformer insulation sleeves are also constantly being improved and perfected. The development trend of future transformer insulation sleeves may include more efficient materials, more advanced manufacturing processes, higher voltage levels, and more comprehensive maintenance management. At the same time, the demand for environmental protection and energy conservation will also have a significant impact on the research and application of transformer insulation sleeves.
