1) Immediately stop the excitation and voltage increase work
2) Quickly disconnect the excitation system and the secondary power switch once
3) Organize personnel to extinguish the fire (if it is a power line, the switch or carbon brush part can be extinguished with a carbon tetrachloride extinguisher or dry powder extinguisher< /p>
Sand cannot be used to extinguish the rotating part of the exciter)<. /p>
4) Find the cause of the fire after extinguishing the fire Analysis
Do not usefoam fire extinguishersto extinguish the fire fire when the generator catches fire.
Do not use a foam fire extinguisher as it conducts electricity. If the equipment power is less than 150 MW, hydrogen cooling and air cooling are recommended. If it is 150 MW, it is recommended to use the rwater cooling. Water cooling is an independent circuit and has no direct contact with the windings and iron core. It is ducted and the windings and iron core can be cooled externally. When using this type of product, be sure to use it in an area 5 meters from burning objects to ensure personal safety. Of course, if it is a shorter range extinguisher, it can be used in an area of 2. meters. However, when using it, it is best to determine it according to the actual situation on site, so that our personal safety can be guaranteed to the greatest extent.
