Найкращий спосіб контролювати температуру гарячої точки контактів на шинках у розподільних пристроях - через вимірювання температури волоконно -оптичної температури

Навіщо комутаційним пристроям високої напруги потрібно стежити за температурою
As a very important electrical equipment in power plants and substations, switchgear has dynamic and static contacts and bus bar joints that are in high voltage and high current working conditions for a long time. Due to factors such as surface oxidation, корозії, ослаблені кріпильні болти, and contact aging, the contact resistance increases at the junction of dynamic and static contacts, as well as at the connection of the busbar. This causes an increase in temperature at the contact or joint, and the degree of overheating will continue to intensify, which will affect the insulation performance and equipment life.
