GOST 17494-87

ГОСТ 17494-87

Rotating electrical machines. Classification of degrees of protection provided by enclosures for rotating machines

Машины электрические вращающиеся. Классификация степеней защиты, обеспечиваемых оболочками вращающих электрических машин

Status: Not effective - Superseded. IUS 2-2013

The standard classifies the degrees of protection provided by the shells of electric rotating machines without limiting power, speed and voltage. The standard establishes the degree of personnel protection against contact with current-carrying or moving parts inside the machine, the degree of protection against the penetration of solid foreign bodies and water into the machine, as well as the designations and test methods for the degrees of protection. The standard establishes the requirements that protective shells must meet. The standard applies only to shells, which in all other respects correspond to their purpose, the materials and design of which, under normal operating conditions, ensure the invariance of any degree of protection prescribed by this standard. The standard does not establish the degree of protection of machines against mechanical damage or against such effects as moisture (resulting, for example, as a result of condensation), corrosive vapors, mold fungi, etc., and also does not indicate ways of protecting machines intended for use in an explosive environment. .

Стандарт классифицирует степени защиты, обеспечиваемые оболочками электрических вращающихся машин без ограничения мощности, частоты вращения и напряжения. Стандарт устанавливает степени защиты персонала от прикосновения к токоведущим или движущимся частям, находящимся внутри машины, степени защиты от проникновения твердых инородных тел и воды внутрь машины, а также обозначения и методы испытаний степеней защиты. Стандарт устанавливает требования, которым должны удовлетворять защитные оболочки. Стандарт распространяется только на оболочки, которые во всех других отношениях соответствуют их назначению, материалы и конструкция которых в нормальных условиях эксплуатации обеспечивают неизменность какой-либо степени защиты, предписанной настоящим стандартом. Стандарт не устанавливает степени защиты машин от механических повреждений или от таких воздействий как влажность (возникающая, например, в результате конденсации), коррозионные пары, плесневые грибы и т. п., а также не указывает способов защиты машин, предназначенных для использования во взрывоопасной среде.
