Уход за электрооборудованием

Как правило, электрооборудование работает надежно. Однако это не означает, что оно не заслуживает внимания. Необходимо часто осматривать оборудование, содержать его в чистоте, смазывать и ремонтировать. Следует немедленно устранять чрезмерный нагрев, вибрацию и искрение.

Нагрев может быть вызван перегрузкой или коротким замыканием между витками, недостатком масла в подшипниках. Вибрация может быть вызвана неправильным фундаментом, дисбалансом в движущихся частях машины.

Проводники могут нагреваться из-за перегрузки или повреждения изоляции проводника.

Электрическая машина любого типа требует определенных условий, при которых она может надежно работать: температура и свободный доступ окружающего воздуха, необходимость защиты от грязи, пыли, тип и продолжительность нагрузки и т. д.

Вращающиеся машины должны быть установлены на прочном фундаменте.

Проводники должны быть защищены от механических повреждений.

Необходимо принять все меры предосторожности.
