The difference between self-starting and self-switching of the four protections of diesel generator sets

With the continuous improvement of automation in recent years, automation assistance in various industries has become more and more mature. Among them, the automatic programs used in diesel engines and diesel generator sets are more and more accepted and trusted by the environment and users. Relying on years of little experience, sum up the differences between the four protections, self-starting and self-switching procedures in the generator set, and help our users of automated generator sets to better understand and master the application.

The editor below will analyze the differences and characteristics of these three commonly used operation methods other than manual:

One and four protection modules

The four protections of the generator set include: water high temperature protection, low oil pressure protection, over current protection, and overload protection.

1. When the water is high, when the temperature of the water tank of the generator set reaches 98 degrees or more, the control module of the generator detects the high temperature of the water and shuts down for protection.

2. When the oil pressure is low, when the oil in the generator is insufficient or reaches the warning level, the generator set will also send out a low oil pressure alarm and shut down.

3. In the case of overcurrent, when the load of the user of the generator set exceeds the rated current of the gasoline generator set, the generator set will also have a shutdown alarm.

4. In case of overload, the generator will also alarm and shut down when the user's load of the generator set exceeds the rated power of the generator. In addition, the gasoline generator set has many other protection parameters such as: low voltage, short circuit, etc., according to the customer According to different needs. Two: self-starting module

The self-starting switch has a signal line input. When the mains power fails, the generator will automatically start the generator when it receives the signal. When the mains power comes, the generator will automatically stop.

Three: ATS self-switching cabinet

Automatic switching control

1. Switch the control switch to AUTO, and cooperate with the automatic power switch (ATS) control switch to be set to the automatic position for use. When the mains power is stopped, A•T•S will give the start signal to the generator control System, the generator will start automatically.

2. When the control switch is switched to STOP, or remains at automatic, but the mains power has been restored, ATS will send a stop signal, and the diesel generator set will automatically stop. Note: When the diesel generator set in operation automatically stops due to a fault (over speed, high water temperature, low oil pressure, etc.), after troubleshooting, the fault reset button must be pressed to prepare for restart. Summarizing the above points: we can see that the realization of the functions from the four protections to the self-starting to the automatic switching of the generator set reflects a stage of increasing automation and technological innovation. From the simple control of diesel engine protection, to the realization of automatic start, to automatic power transmission and closing after automatic start, automatic conversion of mains power to power failure.
