Plug-in type bushings for 72,5 kV with 630 A and 1 250 A for electrical equipment
This document is applicable to plug-in type bushings, according to ENÂ 60137, 72,5Â kV, rated currents from 630Â A up to 1Â 250Â A and frequencies from 15Â Hz up to 60Â Hz for single or three-phase arrangements in electrical equipment like liquid filled transformers or gas insulated switchgear and controlgear. It complements and amends, if necessary, the relevant EN standards.
The application of such plug-in type bushings is derived from ENÂ 50180 and ENÂ 50181 but applied for higher voltages with described deviations to ENÂ 50299-2 and ENÂ 62271-209.
This standard does not cover the connection assembly as described in ENÂ 50299-2 and ENÂ 62271-209.
ENÂ 60137 and HD 632 series outline the qualification, type test, routine and sample test of plug-in type bushings according to this standard.
This document establishes essential dimensions and testing procedures, to ensure adequate mounting and interchangeability of mating plug-in separable connectors of equivalent ratings.
