-
The porcelain bushing of power transformers is an important component of power transformers, mainly used to lead the high and low voltage leads inside the transformer to the outside of the oil tank. It not only serves as insulation for the leads to the ground, but also plays a role in fixing the leads. Ceramic bushings must have the electrical strength and sufficient mechanical strength specified in the manufacturing standards, as well as good thermal stability to cope with the load current and short-circuit current during transformer operation.
Types and structures of porcelain bushings for power transformers
According to different voltage levels and usage environments, power transformer porcelain bushings can be divided into the following types:
Pure porcelain bushing: commonly used in transformers of 10kV and below, its structure is simple, mainly composed of porcelain bushing and conductive copper rod, with air insulation inside the porcelain bushing.
Oil filled bushing: suitable for 35kV level transformers, with oil filled porcelain bushing and insulating paper wrapped around conductive copper rods to improve insulation performance.
Capacitive bushing: Used for high-voltage transformers above 100kV, it consists of a main insulation capacitor core, upper and lower porcelain parts, connecting sleeve, oil pillow, spring assembly, base, voltage equalizing ball, measuring terminal, wiring terminal, etc., and has a high breakdown voltage.
Application scenarios and maintenance methods of porcelain bushings for power transformers
Ceramic bushings for power transformers are widely used in transformers of various voltage levels to ensure the normal operation and safety of electrical equipment. The maintenance method includes regularly checking the appearance of the porcelain bushing for cracks or damage, checking the cleanliness and oil level of the insulation oil, and performing necessary cleaning and fastening work to ensure the electrical performance and mechanical strength of the porcelain bushing.
Through the above introduction, we can better understand the definition, types, structure, application, and maintenance methods of power transformer porcelain bushings in the power system.
