The repair method of HID stabilizer
Technical field
The present invention relates to a kind of motor vehicle illumination with the repair method of stabilizer, is a kind of repair method of HID stabilizer concretely.
Background technology
Stabilizer is the control assembly of HID xenon lamp, and because it is operated in abominable hot environment, inner damage parts is unavoidable, returns goods and central recessiveness or the dominance fault that exists of production, brings serious work load to manufacturer and service personnel.
Summary of the invention
The object of the present invention is to provide a kind of repair method of HID stabilizer, have the damaged location of quick maintenance stabilizer.
The present invention realizes with following technical scheme: the repair method of this HID stabilizer, the instrument of outfit has: multimeter, 12V direct supply, digital electronic ammeter, arcing testing jig, Xe lamp bulb.
The first step is connected the output line of fault stabilizer with the arcing testing jig, the both positive and negative polarity of 12V direct supply is connected with the both positive and negative polarity inlet wire;
Second step, the electric energy of conducting 12V direct supply, the switching tube work of stabilizer, the positive and negative polarities of arcing testing jig must spray spark,
1. if there is not spark, show the high-pressure energy deficiency of stabilizer, must change the turn ratio of more high-tension switching tube or increase high voltage package;
2. spark is arranged, but be less than 2 seconds discharge time, less than normal for the time capacitor volume, the resistance value that needs to change the time capacitor of bigger capacity or increase the time resistor of carrying electric signal;
3. spark is arranged, the fiery arc dia that the range estimation spark produces must reach more than the 3mm, if do not have, the high-pressure fire arc that shows stabilizer is strong inadequately, being not enough to the rapid spread xenon-133 gas, influencing the effect of lighting a lamp, is that energy storage capacitor damages, must change energy storage capacitor, the capacity of two energy storage capacitors is 4.7uf;
4. if no high pressure, and the reometer of 12V direct supply shows up to 10 amperes, is that commutation diode or MOSFET damage, specifically with changing after the multimeter measurement;
5. if no high pressure, and the reometer of 12V direct supply shows only have about 300 milliamperes, is control IC damage;
6. if no high pressure, but switching tube has work, and the reometer of 12V direct supply shows only have about 3.5A, is the damage of high voltage package or ignition capacitor;
7. if no high pressure, but switching tube does not have work or the working time is extreme, less than 0.2 second, for the pipe of switching tube press too high, must replacing;
The 3rd step after more than inspection is passed through, disconnected the output line of detected stabilizer and arcing testing jig, the output line of detected stabilizer was finished with xenon lamp to be connected again; Then, the power supply of conducting 12V direct supply again, stabilizer work,
1. after xenon lamp dodges, extinguish, show that the subsequent current of stabilizer is under-supply, should change the continued flow resistance device, the resistance of continued flow resistance device, a 1K Ω, another 680 Ω is with changing after the multimeter measurement;
2. if light, so, the pointer of reometer should be about 3.5A, drops to about 3A later in one minute, if electric current is too high, it is tired right to cause that vehicle power shortage or xenon lamp start, and must adjust adjustable resistor, makes working current at normal value;
3. after lighting, the shadow of Xe lamp bulb rocks severity, and for the Constant Electric Current container damages, the model of Constant Electric Current container is: thin film capacitor, capacity are 0.15uf ~ 0.22uf;
4. when detected stabilizer work after 15 minutes, be reduced to 2.8A under the electric current, the transformer that shows stabilizer inside heats up too high, must change transformer;
5. after the detected stabilizer work regular hour, the pipe of the xenon lamp of this moment is pressed again in normal scope, and stabilizer quits work, and shows, the control IC of stabilizer damages, and must change control IC;
6. exchange the output both positive and negative polarity of 12V direct supply and the both positive and negative polarity of tested HID stabilizer; namely; the negative pole of 12V direct supply is connect the positive pole of tested HID stabilizer; the positive pole of 12V direct supply connects the negative pole of tested HID stabilizer; at this moment; reometer should not walked about to normally, if reometer is walked about to the reverse protection pipe damages, must change the reverse protection pipe.
The invention has the beneficial effects as follows: have the serviceability of each parts of fast detecting stabilizer, significantly improve maintenance efficiency.
