Complete Package Mounted on Trailers.
Contact Milt Fyre milt@rmaglobal.com 503-351-9898
Each generating set consists of and Avon-powered gas turbine driving A/C generator and exciter through a speed reducing gearbox supplying 10.3 mw base, 16 mw peak (depending on ambient temperature) at 13.8 KV. 60 Hz and is designed for starting without and external A/C supply.
The complete installation is mounted on a main and auxiliary trailer designed for transporting all the necessary equipment by road to any site where it is desired to provide and additional or emergency mains power supply. The plant controls are located in a control room at the front of the auxiliary trailer.
The gas turbine is a liquid fueled Rolls-Royce Avon maxi type 1533-10LL.
For starting the gas turbine is rotated by a 120V D/C motor enclosed within the intake hub fairing. The starter drive incorporates a self-engaging ratchet mechanism.
The power turbine is a single stage unit driven by Avon gas generator exhaust gases.
Power turbine is a single exhaust gases pass through an exhaust duct and silencer to and exhaust stack which discharges the gases to the atmosphere. A splitter type silencer reduces exhaust noise to an acceptable level.
The speed-reducing gearbox is driven by the power turbine through a shaft with flexible couplings. The gear is suitable for full continuous running and can withstand 10% overloads for abort periods. It uses single helical, inviolate gear supported by plain white metal bearings.
The A/C generator is a horizontal salient pole, brushless machine. Excitation is by a revolving armature brushless generator complete with rotation rectifiers and a plot exciter integral with the main exciter. The generator is totally enclosed and cooled by a closed air system. The gas turbine is a fuel-controlled engine, so that the constant conditions of load and ambient atmospheric qualities, engine speed is directly related to the amount of fuel supplied to the gas generator. A Change load requires a related change in fuel supplied to maintain a constant output system and constant A/C frequency the system embodies and electronic governor unit, which monitors critical performance qualities.
