Study low-voltage AC contactor switch arc arcing process change in diameter

In the low-voltage AC contactor is closed and breaking electrical circuits, it will produce an arc between the contacts. Low-voltage AC contactor switch arc in its arc instantaneously reaches a high temperature, and thus would adversely affect low-voltage AC  electri cenergy meter  product performance, reduce the reliability of their products and reduce their electrical life. The main low-voltage AC contactor switch arc arcing during the arc diameter variations and temperature variations and  electric meter  and low-voltage AC contactor switch arc was simulated. Research can improve the contact material, improve the structure and enhance electrical low-voltage AC contactor electrical performance to provide support.
