Overview
This Technical Specification specifies requirements for electric pumps which generate the circulation of insulation liquid in transformers and reactors of rail vehicles and their associated cooling systems. The pumps covered by this Technical Specification are rotodynamic pumps driven by a squirrel cage induction motor which is immersed in the insulating liquid. CLC/TS 50537-2 gives consideration to both technical and normative requirements of the railway environment and restricts the variety provided by industry standards, such as EN 50216-7 and EN ISO 9906. It specifies requirements and tests enabling the interchangeability, especially regarding electrical, mechanical and hydraulic interfaces. Furthermore, operating conditions are described. The responsible Committee is Subcommittee UK 351.1 "Fahrzeuge" ("Rolling stock") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
