The bonitizer is a device that limits the current and generates instantaneous high -pressure equipment. It is made of lacquer cables made of iron cores made of silicon steel. Such a coil with iron core.Self -feeling generated high voltage, which is added to the electrode (filament) at both ends of the fluorescent lamp.The ballast is divided into electronics and inductors.
Ballast price
Overall, the price of a ballast is relatively low, because the ballast is not a high -tech electronic product. He is just an ordinary electrical product.Generally speaking, Philips ballasts are about 25 yuan; Siemenss ballast is about 30 yuan; the price of different brands in the market is different, the price of the Delixi ballast is the priceIts relatively high, get 50 yuan a big one.
What brand of the ballast is good
1. The characteristic of the ABB ballast ABB baller is: energy saving.The electronic ballast of the EEFL ballast lamp of the fluorescent lamp, uses 20 to 60kHz frequency to supply the lamp tube, so that the light effect of the lamp tube is increased by about 10%compared to the industrial frequency (a tube with a length of 4 feet in length), and its own power consumption itself consumes its own power consumption.Low, the total input power of the lamp is reduced by about 20%, which has a better energy saving effect.2. The characteristics of IR international ballast IR international ballast: It can eliminate frequent flashing and more stable glow.It is conducive to improving visual resolution and improving efficacy; reducing visual fatigue of continuous operations is conducive to protecting vision.
Ballast function
The role of the fluorescent lamp ballast is: using the Qihui device to suddenly interrupt the current in the inductance, generate high anti -potential, and lighten the lamp tube after superimposed with the external electricity source; after the lamp tube starts, Avoid excessive current in the lamp, cause damage to the electric light.
Principles of ballast
When the switch is turned off, the power supply adds the voltage between the poles of the Qihui device to discharge the mucus and emit light.The filaments in the ballast coil and the lamp are passed by the current.After the circuit is turned on, the pyropology in the Qihui device stops discharge (the Qihui device is less voltage, the light discharge cannot be carried out, and does not work).At the moment when the circuit is disconnected, due to the sharp decrease in the current of the ballaster, it will generate a high self -sensing motor. The direction is the same as the original voltage direction.Add at the ends of the lamp to make the gas in the lamp began to discharge, so the solar lamp becomes the channel of the current to start glowing.When the fluorescent lamp starts to shine, the coil will generate self -induced electromotive momentum due to the coil of the cross -changing current through the coil of the ballast. It always hinders the changing current. At this timeWork.
