Abstract
The utility model relates to a no-contact capacitance energy-storage locomotive mercury xenon lamp trigger, which is composed of an electric voltage detection and trigger pulse generating circuit, a switching circuit, a storage capacitor, and a first and a second booster transformers. The switching circuit which is composed of thyristor switches on the thyristor by triggering pulse control, and electric is discharged for the booster transformer by means of the storage capacitor. The utility model has the advantages of low failure rate, long life length, simple wire connection, small operating current, high efficiency, and low cost, which is widely used in various kinds of steam and internal combustion electric locomotives at home and abroad.
Description
The utility model relates to locomotive mercury xenon lamp trigger, relates in particular to a kind of contactless capacitance energy storage type locomotive mercury xenon lamp trigger.
The mercury xenon lamp trigger that is used for railway locomotive at present, be traditional mechanical contact-type trigger, because the deficiency on circuit and the structural design, it is serious to make that mechanical vibrator produces spark, make traditional trigger exist always failure rate height, operating current big, can not continuous trigger, defective such as efficient is low, the life-span is short.For this reason, some professional production factories and locomotive depot have carried out research and have improved, but only be on intrinsic basis, to have added the improvement oscillator of electronic circuit or to the trigger process control of delaying time, the contactless trigger of locomotive mercury xenon lamp (notification number is CN20705023U) as Chinese Patent Gazette for Utility Models bulletin, be about to circuits for triggering and change the contactless oscillating circuit of time control into, but do not break through in essence, still have limitation.
The purpose of this utility model is: overcome the above-mentioned defective of prior art, long locomotive mercury xenon lamp trigger of a kind of contactless, safe and reliable, life-span is provided.
The technical solution of the utility model is: utilize silicon controlled triggering and conducting principle, step-up transformer is discharged by controllable silicon by storage capacitor, thereby realization is to the startup of mercury xenon lamp.The utility model produces circuit, switching circuit, storage capacitor and first and second step-up transformer by voltage detecting and trigger impulse and forms.Its switching circuit is made of controllable silicon, and voltage detecting and trigger impulse produce circuit by voltage stabilizing didoe, and diac and other Resistor-Capacitor Unit constitute.
The utlity model has following advantage:
1, adopts contactless capacitance energy storage working method once to boost, greatly reduce failure rate, fundamentally prolonged the trigger life-span;
2, after arc automatic starting triggered (but the sample trigger is in laboratory continuous trigger work 3 hours) mercury xenon lamp work continuously, this trigger just stopped automatically;
3, locomotive control circuit and wiring have been simplified;
4, operating current little (≤80mA), the efficient height;
5, suitably adjust relevant parameter, can be widely used in various steam, internal combustion, electric locomotive.
