Electric car headlights began to take LED lighting technology route

All the headlights of electric vehicles have always used halogen lamps. Compared with the first generation of incandescent lamps, halogen lamps are a variant of incandescent lamps. Inject halogen gases such as iodine or bromine into the bulbs, and sublimate tungsten at high temperatures. The wire chemically reacts with the halogen, and the cooled tungsten re-solidifies on the tungsten wire to form a balanced cycle to prevent premature rupture of the tungsten wire. Therefore halogen bulbs last longer than incandescent lamps. Because of its simple structure and low cost, it has been widely used in electric vehicles and economy cars for many years.

However, with the rapid development of LED technology in recent years, most high-end cars have taken the lead in adopting LED high-brightness lighting. However, due to cost reasons, electric vehicles, especially two-wheeled electric vehicles, use LED highlighting lights, which are rare. There have been many electric vehicles that have been equipped with LED lamp bezels arranged in a matrix. The energy saving effect is greatly improved, but the brightness, penetration and illumination distance are not very satisfactory, so they are only used on very few models.

In recent years, Tailing has invested a lot of energy, manpower and material resources in product innovation and R&D; product innovation has been in a leading position in the industry; the “High-tech” cloud electric vehicle series launched this time--- The new Qingfeng Xia, the wolf 18th generation, Hyun Meng uses the industry's highest technology LED high-brightness energy-saving headlights, which can be lit instantly, and the volume is small, the power consumption is only 1/3 of the halogen lamp, the most critical is the illumination More than 100 meters away, it is 3 times the illumination distance of the halogen lamp and 5 times the brightness. It is safer to form a particularly open suburban section at night.

Applications:

The Grounding Transformer is a kind of auxiliary transformer that used to offer an earth point for the Delta-Star system. They are typically used for providing a path to ground for unbalanced load current and for fault currents on system where a suitable ground is otherwise not available.

Design:

The grounding transformers are generally designed with one of the two configurations: Zig-Zag (Zn) with or without an auxiliary winding or a Wye (Ynd) with a delta connected secondary. The Zig-Zag connection is preferred as it is more cost effective and have smaller size than the Delta-Wye unit. For more safety, neutral earthing resistors (NER) are often used in conjunction with the grounding transformer to limit neutral ground fault current magnitude. The rated voltage of the NER should be equal to the line to ground voltage of the grounding transformer. The current rating and duration should match the grounding transformer
