Three methods of maintenance of electronic ballasts

by:MOSO     2020-03-09
Maintenance method of electronic ballasts, basically have the appearance test, waveform observation and multimeter measurement method of the three basic to ballast for repair: 1, the appearance of the test is to open the shell of electronic ballasts, observation components whether there are abnormal. If the 'fat' or blowout, electrolytic capacitor it has spoiled or breakdown. Most of the electronic ballast adopt fine enameled wire to replace the fuse, once burned, will leave black burn mark on the printing plate, and very obvious that the encapsulation body tube burst power switch. Certificate has been destroyed, must be replaced. 2, the electronic ballast of waveform observation with the aid of oscilloscope to observe the important check point of waveform, for internal excitation push-pull oscillation circuit, power switching transistor ( C, E or extremely VDMOS field-effect tube between D and S pole) The square wave output waveform drought, amplitude of about 260 v. 3, multimeter measurement method is known to use multimeter R x 1 n profile is easy to detect the resistance capacity online components or whether the semiconductor device breakdown. In electronic ballast circuit, yu with the resistance method of online measuring power switching device and bidirectional trigger diode for open circuit has the certain difficulty, is a reliable method is to weld down again detection. Because of its power is relatively small, so there is no installation stream ( Protection) Diode, that is, using a multimeter R x 10 ki] , s, G and D to the question of arbitrary polarization resistance, whose hands were not deflect. Electric light up every inch of space for everyone, we can according to customer requirements and the actual use of the environment, customized products and provide integrated solutions for customers, for the general customers to provide quality and efficient products. We look forward to cooperate with customers and friends from all over the world hand in hand, create brilliance. Service hotline: website: ali website, https://
