SIST EN 60947-8:2003

Low-voltage switchgear and controlgear -- Part 8: Control units for built-in thermal protection (PTC) for rotating electrical machines

Specifies rules for control units, which perform the switching functions in response to the thermal detectors incorporated in rotating electrical machines according to IEC 60034-11, and the industrial application. It specifies rules for that type of system comprising a positive temperature coefficient (PTC) thermistor detector having particular characteristics, and its associated control unit. The PT100 detectors are covered by IEC 60751, where the resistor values are given according to the temperatures of the detector. The present rules lay down the characteristics of association of this particular positive temperature coefficient thermistor detector and its associated control unit (designated "Mark A detector"" and "Mark A control unit""), when they are used in thermal protection systems. NOTE It is not possible to specify all the requirements for the operating characteristics of a control unit, as they are dependent on some aspects of the thermal detectors. Some aspects of the requirements of the thermal protector system can only be specified when account is taken of the characteristics of the rotating machine to be protected and the method of installation of the detector within the machine. For these reasons, for each characteristic it is necessary to specify who is responsible for stating the required values and who is responsible for compliance with the requirement and for carrying out any confirmatory test.

Appareillage à basse tension -- Partie 8: Unités de commande pour la protection thermique incorporée (CTP) aux machines électriques tournantes

Spécifie les règles pour les unités de commande, qui réalisent les fonctions de commutation en réponse aux détecteurs thermiques incorporés aux machines électriques tournantes selon la EN 60034-11, et l'application industrielle. Elle spécifie les règles pour ce type de dispositif comprenant un détecteur à thermistance à coefficient de température positif (CTP) ayant des caractéristiques particulières, et son unité de commande associée. Les détecteurs PT100 sont couverts par la EN 60751, où les valeurs de résistance sont données selon les températures du détecteur. Les présentes règles fixent les caractéristiques de l'association de ce détecteur à thermistance à coefficient de température positif particulier et de son unité de commande associée (désignés par "Détecteur A" et "Unité de commande A"), lorsqu'ils sont utilisés dans des dispositifs de protection thermique. NOTE Il n'est pas possible de spécifier toutes les prescriptions pour les caractéristiques de fonctionnement d'une unité de commande, puisqu'elles sont dépendantes de certains aspects des détecteurs thermiques. Certains aspects des prescriptions du dispositif de protection thermique peuvent seulement être spécifiés lorsque sont pris en compte les caractéristiques de la machine tournante à protéger et le mode d'installation du détecteur dans la machine. Pour ces raisons, il est nécessaire de spécifier, pour chaque caractéristique, qui est responsable de la déclaration des valeurs requises et qui est responsable de la conformité aux prescriptions et de l'exécution de tout essai de vérification de la conformité.

Nizkonapetostne stikalne naprave – 8. del: Krmilne enote za vgrajeno toplotno zaščito (PTC) rotacijskih električnih strojev (IEC 60947-8:2003)

Določa pravila za krmilne enote, ki opravljajo stikalne funkcije kot odziv na toplotne detektorje, vgrajene v rotacijske električne stroje v skladu s standardom IEC 60034-11, in industrijsko uporabo. Določa pravila za to vrsto sistema s termistorskim detektorjem s pozitivnim temperaturnim koeficientom (PTC) s posebnimi značilnostmi in z njim povezano krmilno enoto. Detektorji PT100 so zajeti v standardu IEC 60751, pri čemer so vrednosti upora podane v skladu s temperaturami detektorja. Ta pravila določajo značilnosti povezave tega termistorskega detektorja s pozitivnim temperaturnim koeficientom in z njim povezane krmilne enote (pri čemer sta označena kot »detektor z oznako A« in »krmilna enota z oznako A«), kadar se uporabljata v toplotnih zaščitnih sistemih. OPOMBA Vseh zahtev za obratovalne značilnosti krmilne enote ni mogoče določiti, saj so odvisne od nekaterih vidikov toplotnih detektorjev. Nekatere vidike zahtev toplotnega zaščitnega sistema je mogoče določiti le ob upoštevanju značilnosti rotacijskega stroja, ki bo zaščiten, in metode vgradnje detektorja v stroj. Zato je treba za vsako značilnost določiti, kdo je odgovoren za navedbo zahtevanih vrednosti, skladnost z zahtevo in izvedbo morebitnih potrditvenih preskusov.
