Overview
SIST EN 50180-3:2016 is a European standard that specifies requirements for bushing fixations used in liquid-filled transformers with voltage ratings above 1 kV up to 52 kV and current ratings from 250 A to 3.15 kA. This standard is part three of the EN 50180 series and supplements the general and component requirements outlined in EN 50180-1:2015 by providing detailed constructional design requirements for bushings' fastening elements. It is essential for utilities and manufacturers to ensure compatibility and interchangeability of bushings and their fixations, especially when dealing with high-voltage transformer installations.
This standard was approved by the European Committee for Electrotechnical Standardization (CENELEC) and mandates harmonized fixation dimensions and materials, aiming to enhance safety, reliability, and ease of maintenance for transformers using bushings within the specified voltage and current range.
Key Topics
Scope and Compatibility
EN 50180-3 should be applied in conjunction with EN 50180-1. It specifically addresses fastening details including flange rings and clamping paws for bushings. The standard covers fixations for transformers with voltages up to 52 kV and currents between 250 A and 3.15 kA.Fixation Components and Dimensions
The fixation system consists primarily of flange rings and clamping paws. The standard defines sizes, dimensions, and tolerances ensuring fit and interchangeability:- Flange rings are categorized as types A, B, C, and D, each tailored for specific current ratings and mechanical stability requirements.
- Clamping paws, designated E and F, come in different sizes to suit various bushing ratings and voltage classes.
- Dimensions and tolerances for these components align with EN 22768 general tolerances to guarantee precision.
Materials and Construction Details
The standard recommends the use of non-corrosive materials for flange rings and clamping paws, mainly aluminum sheets and non-magnetic metal sheets, to ensure durability under operating conditions. The thickness and material specifications vary according to the type of flange ring and application.Compatibility and Interchangeability
Detailed dimension tables and figures facilitate clear understanding for utilities and manufacturers, helping them to ensure compatibility between bushings and transformer connection points. Certain diameter deviations are allowed but require agreement between purchaser and manufacturer to maintain interchangeability.Referenced Standards
EN 50180-3 mandates normative references such as EN 50180-1 for general bushing requirements and EN 22768 series for tolerance standards, ensuring comprehensive and aligned implementation.
Applications
Transformer Manufacturing and Installation
The standard is critical for transformer manufacturers involved in designing and supplying bushings for liquid-filled transformers rated above 1 kV and up to 52 kV. It guides the construction of robust and compatible fastening systems, which are vital for transformer reliability.Utility Companies and Maintenance
Utilities rely on EN 50180-3 for standardization in bushing fixations to facilitate maintenance, replacements, and upgrades without compatibility issues. This leads to reduced downtime and safer operations, especially in medium voltage power transformers.Quality Assurance and Standard Compliance
Adhering to EN 50180-3 ensures compliance with European safety and technical standards in transformer components, supporting quality certification processes and market acceptance across the EU.
