CLC/TS 50537-4:2010

Railway applications - Mounted parts of the traction transformer and cooling system - Part 4: Gas and liquid actuated (Buchholz) relay for liquid immersed transformers and reactors with conservator for rail vehicles

This Technical Specification covers gas and liquid actuated (Buchholz) relays for liquid immersed transformers and reactors with conservator for rail vehicles. The device is intended to detect • gas release from the unit to be protected, • cooling liquid surge from the protected unit to the conservator, • complete loss of the cooling liquid in the conservator. This Technical Specification gives consideration to both technical and normative requirements of the railway environment and restricts the variety in particular provided by the industry-wide standard EN 50216-2. It determines requirements and tests enabling the interchangeability of Buchholz relays by defining the following types of interfaces: • mechanical interface, e.g. flanges for pipe connection, dimensions; • electrical interface, e.g. supply voltage for making and breaking capability; • functional interface, e.g. protective operational behaviour. It is not applicable to flameproof relays. Different liquids may be used, which are typically used for both cooling and insulating. Furthermore, operating conditions are described.

Železniške naprave - Vgrajeni deli za transformatorje vlečnih tokokrogov in hladilni sistem - 4. del: Plinsko in tekočinsko vzbujani rele (Buchholz) za v tekočino potopljene transformatorje in dušilke z raztezno posodo, za vozna sredstva

Ta tehnična specifikacija zajema plinsko in tekočinsko vzbujane releje (Buchholz) za v tekočino potopljene transformatorje in dušilke z raztezno posodo za vozna sredstva. Naprava zaznava . uhajanje plina iz zaščitene enote, . izbruh hladilne tekočine iz zaščitene enote v raztezno posodo, . popolno izgubo hladilne tekočine v raztezni posodi. Ta tehnična specifikacija obravnava tehnične in normativne zahteve za železniško okolje in omejuje število različnih delov, ki jih omogoča standard v industriji EN 50216-2. Z opredelitvijo naslednjih vrst vmesnikov določa zahteve in preskuse, ki omogočajo medsebojno zamenljivost Buchholzevih relejev: . mehanski vmesnik, npr. prirobnice za cevne povezave, dimenzije; . električni vmesnik, npr. napajalna napetost za vklop in izklop; funkcionalni vmesnik, npr. zaščitno delovanje. Ne velja za ognjevzdržne releje. Lahko se uporabljajo različne tekočine, ki se praviloma uporabljajo za hlajenje in izolacijo. Opisani so tudi delovni pogoji.
