Fully motorised cubicle leads to more safe, reliable and easy to use AIS switchgear.

Abstract

Full motorization of Air Insulated Switchgear inside primary Medium Voltage cubicle brings a lot of advantage in terms of safety and easiness of operation. It includes electrical operation of circuit breaker, racking device and earthing switch.Proposing more systematically electrically motorized cubicles is the occasion to rethink their control architecture and to get benefit of digital technologies. The aim of this paper is to analyse in a systematic way how they can help to optimize motorization into cubicle with the same level of performance, proposing in the same time new helpful functionalities.
