Performance Upgrading Of Cummins Diesel Generator Set

1. Applicable scope of Cummins automation unit

Cummins automatic diesel generators are widely used in factories, banks, posts and telecommunications, hospitals, high-rise buildings, commercial buildings, industrial and mining enterprises, oil fields, highways, ports, sports and entertainment venues and other departments as common or emergency power supply for communication, power and lighting.

2. Structure and purpose unit design

The structure and purpose of Cummins automatic diesel generator unit are designed with advanced control system and special program controller. When the mains power is lost, phase loss and undervoltage, it can automatically start the unit and put it into operation for power supply; In case of failure, the audible and visual alarm device will automatically alarm, memorize the failure point, and automatically unload and shut down to ensure the safety of the unit. The control screen adopts full Chinese fluorescent display screen and soft touch switch, which has the characteristics of good hand feeling, clear display and reliable action. At the same time, the control panel of automatic grid connection of more than two units can also be designed for users, so that the regulation process is very fast, accurate and stable, and the performance is stable and reliable.

3. Performance introduction of Cummins automatic diesel generator

a. Automatic start and input function

When the mains power grid stops power supply or the mains voltage is lower than 80% of the rated value, the unit will start automatically. After successful start, power will be supplied to the load. The whole process of successful one-time start is controlled within 15 seconds. With remote interface, the start delay can be set to realize the automatic start and shutdown of the generator unit.

b. Auto exit function

During the self generating output of the generator set in the automatic state, if the mains power is restored and confirmed for 30 seconds, the unit starts to execute the automatic exit procedure, the unit will first cut off the load, restore the mains power supply, and then automatically shut down after 2 minutes of cold operation. If the mains power supply stops during the operation of the refrigerator, the unit will automatically adjust the speed to restore the power supply to the load.

c. Pre alarm / fault protection function

Low battery voltage, charging failure, over-current, low oil pressure and high water temperature, with pre alarm function, that is, the value does not stop when the alarm is given, and the alarm light flashes at this time; When the value exceeds the shutdown value, the oil engine will fail and stop. Low speed, overspeed, frequency overrun, voltage overrun, emergency stop and startup failure have fault protection function. If the input value of a certain analog quantity is greater than the upper limit or less than the lower limit, the corresponding high / low delay will start. After the delay, the value throw does not return to normal, the oil engine will stop immediately and the alarm light will be on for a long time.

d. Automatic charging function

The unit can automatically charge the start-up control battery during mains power or self generation. The charging system adopts switching power supply, which can charge the battery in two stages.
