Engine fire explosion:

The inside of the generator has a strong abnormal sound, on both sides of the end cap has burnt smell. The generator internal cooling of the gas pressure increased or decreased substantially increased, the outlet air temperature. Drop of hydrogen purity, with purity and hydrogen pressure drop, the abnormal fluctuation.

Engine fire treatment:

Quickly generator emergency solution column demagnetization. Report the value of long, cut off the source of hydrogen. When there is a fire, should immediately use fixed fire extinguishing device (carbon dioxide). If there is no fire extinguishing device fixed or fire extinguishing device failure and can not be used, we should take advantage of all the fire-fighting equipment to the fire in time, but do not use foam fire extinguishers or fire with dry sand. When an oil fire on the ground, can use dry sand fire, but pay attention not to make the bearing dry sand falls to the generator exciter or on. During the engine fire its cooling water system to normal operation, should continue to run not to stop water supply, but note that pressure should be in a proper range. Until the fire is put out completely so far.

The generator is determined after the fire, immediately splitting demagnetization, report the value of long. Fire extinguishing device and open (carbon dioxide), prohibited the use of foam fire extinguisher and sand to put out the fire.

The generator internal explosion, fire fault phenomenon:

A strong explosion inside the generator, on both sides of the end cap of smoke, a burnt smell; large amplitude wave generator internal hydrogen pressure (increase or decrease), increased export hydrogen temperature, hydrogen purity lowering, generator meter indicating action may be internal protection of basic normal or generator.

The generator internal explosion, fire fault treatment:

Protection of non action, should be immediately hit the gate shut down, removal of excitation; quickly cut off the supply of hydrogen generator is filled into the door, to CO2, the speed of the generator is reduced to 200 300r/mil, according to the regulations of fire extinguishing fire.
