Product Description Main structure of the generator setNatural gas generator sets include natural gas-fueled reciprocating internal combustion engines, alternators, electrical parts, control devices, cooling systems, lubrication systems, exhaust systems, fuel systems, and auxiliary equipment. Except for the exhaust pipe and silencer of the exhaust system, they are mounted on a steel chassis. The generator set is a fixed permanent installed generator set. The steel underframe is mounted to the concrete foundation.The basic structure of the gas engineCummin is the leading brand of engine over the world. We use an original engine manufactured by an authorized Cummin China factory in the USA as a power source for a generator set. The Cummin engine has the characteristics of low gas consumption, low exhaust temperature, great reliability and low maintaining price. The main structure of Cummin engine is high-strength double-walled, improved wide body, significantly increasing the reliability and durability of the engine. The four-valve design effectively increases charging efficiency.2.4 AlternatorThe brushless constant-voltage synchronous alternators are of the self-excited type with an electronic voltage regulator integrated in the excitation system. They are used as main or standby units in land based power installations and for ships' electrical systems and can be driven by internal combustion engines or gas, steam and water turbines and electric motors.Structure: The alternator comprises the main machine exciter and excitation system. The main machine is of revolving magnetic field with cylindrical rotor and damper winding. The exciter is revolving armature machine. The exciter power is supplied to the rotor of the main machine via rotating rectifiers.2.5 Genset controllerThe control panel can detect the current, voltage, speed, frequency, power, engine cooling water temperature, engine oil pressure, exhaust temperature, number of starts, running time, etc. of the unit. The screen also designed a variety of necessary protections for the generator set to ensure safe and stable operation of the unit. The main protections include high water temperature, low oil pressure, overspeed, high temperature, over voltage, under voltage and low frequency. The control panel provides DC power switch, emergency stop button, and unit fault alarm indication.The controller is an easy-to-use control unit containing all necessary functions for protection and control of a genset. It can be used as a single unit for one genset, or it can be connected in a complete power management system with up to 32 controllers for synchronising projects, island or parallel to the mains. The power management system handles the load sharing between gensets and the load-dependent start and stop. The controller contains all necessary 3-phase measuring circuits, and all values and alarms are presented on the sun proof LCD display.
