Automation of Electrical Isolators/ Disconnector using Electrical Motor and Gearbox
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 4
Abstract
Electrical Isolators have been used primarily before circuit breakers in a power transmission substation. Circuit Breakers are used to isolate the circuit. The break points cannot be viewed externally as they lie within the circuit breaker. Electrical Isolators are therefore physical switches that are in place to ensure that the complete connection or disconnection to the whole circuit is made. It is very essential safety switch. These Electrical Isolators used in substations are manually handled, to open or close the Electrical Isolator/ Disconnector switch. This process is hazardous for the person operating the Isolators/ Disconnectors. Therefore, to automate the operation an electric motor can be used. This motor can be used to operate the Electrical Isolator/Disconnector switch remotely. A gear box needs to be designed to give necessary output speed needed to operate the electrical Isolator/Disconnector switch mechanism. Hence, in this project a speed reducer gearbox has been designed for two electrical motors with powers: 0.5 HP and 1 HP. The gearbox uses spur gear pair and worm gear pair to get the necessary output speed.
