Automatic electrical controls - Part 2-22: Particular requirements for thermal motor protectors

IEC 60730-2-22:2014 applies to the partial evaluation of thermal motor protectors as defined in IEC 60730-1 for household and similar use, including heating, air conditioning and similar applications as well as for sealed (hermetic and semi-hermetic type) motor-compressors. A thermal motor protector is considered an integrated control since its protective functionality is dependent on the correct mounting and fixing in or on a motor and which can only be fully tested in combination with the relevant motor. This dependency is illustrated by: - the ability of the thermal motor protector to accurately and reliably sense the heat of the motor windings; - thus, addressing the over-temperature protection due to motor overload conditions; - the ability of the thermal motor protector to accurately and reliably sense the current due to motor locked-rotor conditions; - thus, reducing the response time and not being adversely affected by heat-sink at the assembly spot in the application and the influence of the motor's electromagnetic field on the switch behaviour of the thermal motor protector; - particularly, affecting the arc direction between the contacts resulting in uneven wear of the contact material and eventually leading to failure of operation. Requirements concerning the testing of the combination of sealed (hermetic and semi-hermetic type) motor-compressors and thermal motor protectors are given in IEC 60335-2-34. This standard applies to thermal motor protectors using NTC or PTC thermistors, additional requirements for which are contained in Annex J. Key words: Thermal, Motor protectors, Integrated control

Automatische elektrische Regel- und Steuergeräte - Teil 2-22: Besondere Anforderungen an thermisch wirkende Motorschutzeinrichtungen

Dispositifs de commande électrique automatiques - Partie 2-22: Exigences particulières pour les protecteurs thermiques

L'IEC 60730-2-22:2014 s'applique à l'évaluation partielle des protecteurs thermiques tels que définis dans l'IEC 60730-1 pour usages domestiques et analogues, y compris pour le chauffage, l'air conditionné et applications analogues, ainsi qu'aux motocompresseurs étanches (de type hermétique et hermétique accessible). Un protecteur thermique est considéré comme un dispositif de commande intégrée, sa fonction de protection dépendant de son montage et de sa fixation correcte dans ou sur un moteur, et qui ne peut être complètement soumis à essai qu'en association avec le moteur concerné. Cette dépendance est illustrée par: - l'aptitude du protecteur thermique à détecter de manière précise et fiable la chaleur des enroulements du moteur et donc à assurer, la protection contre la surchauffe en raison des conditions de surcharge du moteur; - l'aptitude du protecteur thermique à détecter de manière précise et fiable le courant en raison de conditions de rotor bloqué et donc, à réduire le temps de réponse et à ne pas être affecté par le dissipateur thermique sur le lieu d'assemblage dans l'application; - l'influence du champ électromagnétique du moteur sur le comportement du commutateur du protecteur thermique, affectant, en particulier, la direction d'arc entre les contacts résultant d'une usure inégale du matériau de contact, et donnant éventuellement lieu à une défaillance de fonctionnement. Les exigences relatives à l'essai de la combinaison des motocompresseurs étanches (de type hermétique et hermétique accessible) et des protecteurs thermiques sont données dans l'IEC 60335-2-34. La présente norme s'applique aux protecteurs thermiques utilisant des thermistances CTN ou CTP, dont les exigences supplémentaires sont contenues dans l'Annexe J.
