Product Applications
Product advantages
Improve arc extinguishing
The permanent magnet blowing arc extinguishing technology generates a strong magnetic field near the arc, so that the arc is wound into a spiral shape, increasing its length and resistance, thereby accelerating the dissipation of energy and achieving the purpose of quickly extinguishing the arc. This technology can significantly improve the arc extinguishing performance of the relay and the service life of the contact.
Enhance contact impact resistance
In the high voltage DC system, because the DC current does not exist zero crossing, the arc is more difficult to extinguishment, which is easy to lead to serious contact ablation, reducing the electrical life and reliability of the product. By speeding up the breaking speed of the contact and improving the blowing magnetic field, the arc blowing technology of permanent magnet can effectively reduce the damage of the arc to the contact and improve the impact resistance of the contact.
Adapt to high voltage
The high voltage DC relay needs to cut off the circuit at high voltage, and the permanent magnet blowing arc technology can quickly cut off the high voltage DC load, avoid the occurrence of abnormal conditions such as contact adhesion or relay explosion, and ensure driving safety. This technology is especially suitable for high voltage applications such as new energy vehicles and charging piles.
Improved reliability
The combination of the permanent magnet blowing arc technology and the design of the HVDC relay enables fast and reliable circuit switching. This is particularly important for applications under complex working conditions such as new energy vehicles, because these occasions usually require the relay to be able to successfully cut off the circuit at the limit of large current.
Miniaturization & lightweight
High-voltage DC relays using permanent magnet arc blowing technology can be miniaturized and lightweight, while filling hydrogen with high arc cooling capacity through sealing technology to further improve their arc extinguishing performance and reliability.
