Description
Technical field
The utility model relates to a kind of Gas Turbine Generating Units high energy ignition units.
Background technique
Currently, the combustion engine unit for production is mainly used for emergency power generation, starts band and carry speed and start success rate
It is the performance indicator extremely paid close attention to using side.In generating set starting process, after lighting a fire successfully, fire at different ambient temperatures
Fuel delivery needed for machine is different, and still, startup of unit curve is solidificated in combustion engine controller, is adaptable to adjust in factory
Environment temperature and atmospheric pressure when examination, therefore in actual operation, after often there is winter speed hang-up and summer turbine
The phenomenon that fuel gas temperature overtemperature, influences startup of unit success rate.In order to better adapt to market needs, it is necessary to improve startup of unit
Success rate, can input for safety emergency in the in case of emergency shortest time.
Utility model content
The purpose of the utility model is to provide a kind of Gas Turbine Generating Units high energy ignition units.
Above-mentioned purpose is realized by following technical scheme:
A kind of Gas Turbine Generating Units high energy ignition unit, composition includes: igniter, firing cable and semiconductor
Sparking plug, it is characterized in that: the igniter is connect with one end of the firing cable, the other end of the firing cable
It is connect with the semiconductor discharge plug, the igniter DHZ-72A is low pressure point firearm, and the semiconductor discharge plug is
BDZ-53F sparking plug.
The Gas Turbine Generating Units high energy ignition unit, the semiconductor discharge plug is interior to be arranged combuster, institute
There is light diesel fuel, the ignition end and insulator joint of the semiconductor discharge plug are to use semiconductor in the combustion chamber stated
Material wraps up central electrode, and the semiconductor material is filled between central electrode and shell.
The Gas Turbine Generating Units high energy ignition unit, the semiconductor discharge plug material are titanium dioxide.
The utility model beneficial effect achieved is:
1. the utility model can better adapt to market needs, unit starting success rate is improved, it can be urgent
In the case of input for safety emergency in the shortest time.The utility model has single spark energy height, surface carbon deposit and tide
The wet influence very little that arc discharge is formed to semiconductor surface, and in discharge process, carbon deposit will be burned off, and humidity also will be automatic
The advantages that removing, not will lead to spark energy decline.
2. the utility model generates spark using the high electric field pulse of igniter, indoor fuel (the light bavin of burning is lighted
Oil).The DH-7 ignition coil used originally is replaced to add SDZ-2A erosion igniter igniting system with low pressure point firearm with semiconductor discharge plug
System.The advantages of this improvement is to engine original design change amount minimum, and igniter is constant, and startup program is constant.Pass through improvement
Ignition system, ignition energy greatly improve, and other parameters and program are constant.The improved single spark energy of ignition system reaches
1J or more is far longer than the spark energy of original system.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Attached drawing 1 is the igniter interface diagram of the utility model.
Attached drawing 2 is the appearance schematic diagram of the semiconductor body sparking plug of the utility model.
Attached drawing 3 is the top view of attached drawing 2.
In figure: 1, igniter, 2, firing cable, 3, semiconductor discharge plug.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1:
A kind of Gas Turbine Generating Units high energy ignition unit, composition include: igniter 1, firing cable 2 and partly lead
Body sparking plug 3, the igniter are connect with one end of the firing cable, the other end of the firing cable with it is described
Semiconductor discharge plug connection, the igniter DHZ-72A low pressure point firearm, the semiconductor discharge plug be BDZ-53F electricity
Mouth.
Embodiment 2:
According to Gas Turbine Generating Units high energy ignition unit described in embodiment 1, it is arranged in the semiconductor discharge plug
Combuster has light diesel fuel in the combustion chamber, and the ignition end of the semiconductor discharge plug connects with insulator
Place is to be wrapped up central electrode with semiconductor material, and the semiconductor material is filled between central electrode and shell.
Embodiment 3:
The Gas Turbine Generating Units high energy ignition unit according to embodiment 1 or 2, the semiconductor discharge plug material
For titanium dioxide.
Embodiment 4:
Ignition system matches low pressure point firearm using semiconductor discharge plug.The reason of selecting semiconductor discharge plug is semiconductor
The breakdown voltage of sparking plug is lower, is usually no more than 1000V, and breakdown voltage is unrelated with air pressure, spark energy is not with air pressure
Change and change.Semiconductor discharge plug does not have spark gap, and ignition end and insulator joint are with semiconductor material (two
Titanium oxide TiO2) central electrode is encased, electric discharge is carried out along semiconductor surface.Semiconductor material is filled in central electrode and shell
It is very close to each other for sealing between body, between them.Since semiconductor adulterates more, electricity close to sparking plug ignition end surface portion
Subnumber amount is big, and when two electrodes of sparking plug add voltage, semiconductor surface will have larger current to flow through, to make sparking plug table
Face fever, heat decline the resistivity of semiconductor, further increase electric current, and sparking plug surface temperature further increases, thus
So that semiconductor surface is generated hot dissociation, generates arcing events, this electric discharge along semiconductor surface between final electrode
Phenomenon is formed in the steam ionosphere by semiconductor surface, is not the punch-through of the air gap.Semiconductor discharge plug is hit
It is very low to wear voltage, without specific rated value.The experiment proved that: it is existing that 55V can just make the surface of semiconductor discharge plug generate electric discharge
As.If applied voltage reaches 800~2000V, semiconductor discharge plug electric discharge is exceedingly fast.
